How to strengthen your garage door and protect your premises

Strengthening garage doors

Strengthening the garage door is one of the components of the room equipment. After all, this is the protection of the premises, so we will consider this work to be the main one. We will tell you how to strengthen a garage door in this article.

Here everything can be done with your own hands and therefore the price of the work is not high. Here the quality of execution will come to the fore. There are a lot of photos on this topic, now we will summarize them and choose the most useful and necessary.

You have to strengthen your garage door even if you purchase an expensive product from a well-known brand. And if your garage is equipped with regular swing gates. then know that the frame of such a structure must be carefully strengthened, so you must understand this.

• To do this, you need to weld a metal belt to the gate; this is done with inside, then the design turns out to be more reliable and practical, as it should be.
• You also need to pay attention to the stiffeners, because the metal should not “play”.

Distribution of stiffeners in the gate

Attention: It is important to remember that the garage door must comply necessary requirements security. For example, on their outer side there should never be handles without protrusions, because thefts of cars and other items often occur in such garages, remember this.

• But in order not to encounter such a problem, and to eliminate the possibility of breaking the lock, during installation you need to prepare a special recess on the surface of the gate, after which you can install the lock.
• If you want to rent out your garage, then know that you must put a reliable and high-quality lock on the gate (see Garage locks with a secret: which one is better), because in any case, then you will find a tenant faster.
• I would like to note that first you need to remove the old gate from the hinges, laying them on a flat surface, as for the fastening, everything old needs to be removed, this also applies to the hinges, then they need to be put in place, but in intact and working condition, of course same.
• The gates need to be covered with sheets of metal, the sheets are usually secured using self-tapping screws, and the screws should be positioned in such a way that they can fit into the middle of the beams; if you notice that the sheets will protrude at the edges, then they need to be bent inward. After all, this is done, first of all, to get a more attractive appearance.
• In those places where the gates will be attached to the walls, it is necessary to install steel corners made of rolled steel, and in the places where the gates are attached, fittings must be installed, because this is an important condition.
• Now you can install gates, doing it efficiently and carefully, without having experience in this area, of course, it will not be possible to do this accurately and correctly.

Garage security: what you need to do

Of course, you want to be able to stay in your garage with special security, but you need to understand that any building has vulnerabilities that can be exploited by intruders, so your main task is to find out where these places are and make sure that no one I couldn't get into them.

Attention: When purchasing ready-made gates, be sure to look at the installation recommendations. There they pay attention to security issues. There are also recommendations there.

• If the garage is a permanent concrete structure, then you should know that additional cementation of the metal hooks is necessary.
• To properly strengthen the walls of the garage, it is customary to make a special metal frame from the corners; they, in turn, must have the appropriate size, remember this.
• The frame needs to be boiled metal mesh, of course, it is best to carry out such work during construction, but if changes will be made to an already finished structure, then the frame is best built indoors, of course, if the space allows this.

Attention: Remember that you must carefully try to strengthen the garage door, because it is through them that intruders often enter such premises, which means pay special attention to this place.

• You can weld special metal rods onto garage hinges, and they, in turn, will seriously complicate sawing, so this condition is important. WITH reverse side The gate needs to be welded with bolts and nuts, while additionally securing the hinges, do not forget about this.
• So that the doors can reliably press against each other, you need to install eccentric locks (see Locks for garage doors: types and features), making sure to do this. On one of the gate leaves, you will need to weld a wide metal strip; it, in turn, will not allow you to insert a crowbar or any other tool between the leaves, so you definitely need to know about this important advice.
• The hinges intended for the padlock must be cut off and completely removed inside the surface of the gate, if, of course, there is such an opportunity, while not forgetting to leave a minimum opening that serves for hanging the lock.
• To protect your garage from uninvited guests, you can install a simple alarm that will go off when the gate is opened.

Conclusion

Every owner wants to properly protect the property of his garage from theft, this also applies to his car. Therefore, it is necessary to strengthen garage doors by any means, now you know how this is done, besides this, it is imperative to think about the safety of the garage as a whole, today such problems are easily and effectively solved, so it all depends only on you.

If you contact specialists, they will always help you choose one or another way to protect your garage. But now you know exactly how you can strengthen the gate from this room, the decision is yours. The instructions will help you in this matter.

Of course it needs to be strengthened. For some reason, there are more and more people wanting to profit “for free” from other people’s goods every day. It is very important to minimize their chances. Even the appearance of a strong and high-quality gate can scare away lovers of easy money. It’s better to forget about padlocks altogether (there are unique ones that have only them in garages) - they are cut off in 3 seconds. Well, it’s best to duplicate all security measures GSM alarm- fortunately they are already cheap.

A garage is primarily necessary for secure storage of a car. In addition, many car enthusiasts set up a workshop, cellar, warehouse in it, and keep numerous spare parts, tools, and seasonal tires in the garage. It is important to know how to protect your garage from being opened. Today we will look at the most significant factors effective methods. Let's find out how the protection of the premises differs depending on the type of materials from which the garage is built. Having learned numerous useful tips, everyone will be able to ensure safety in their garage.

It turns out that the protection of a garage largely depends on what material it is made of. Let's look at all the main types of garages, find out how safe it is to store a car in them, and how you can enhance protection.

• Monolithic reinforced concrete structure. This the best option for the garage, so that it is truly durable, reliable, and ensures safety. This design can be ordered at a Russian reinforced concrete products plant. Of course, you will need craftsmen and appropriate specialized equipment for its transportation and installation. But in this garage it is quite difficult to break through the wall. With good hinges and locks, gates, the structure will become impregnable.
• Brick garages. These structures can also be very durable. But everything depends on the material and the quality of the masonry. In addition, there is a weak spot: the floor slabs on the gates. Criminals lift them with jacks, providing clearance for themselves. Experienced garage workers simply attach such a plate directly to the garage door frame, ensuring the integrity and reliability of the structure.

• Metal buildings. Unfortunately, widespread garages made of corrugated sheets are becoming the least protected. Even teenagers can handle them without much difficulty. The metal panels themselves are vulnerable. In addition, there is a danger that the entire structure will simply be lifted above the ground. The problem is also in the thickness of the metal: if it is thin, the garage is opened with a simple device that resembles a familiar can opener. Therefore, it is important to use thick, durable metal. A good solution is a sectional garage, which is assembled on site. Of course, the floor must be connected to the walls. It is also worth taking care of pouring the foundation so that it cannot be undermined.

When you have the opportunity to choose, it is better to choose a ready-made monolithic reinforced concrete garage. If it is not there, you will need to strengthen the existing structure.

Important points

The following factors are also significant. If you are looking for a new garage, pay attention to the following points.

• It is advisable to have neighbors with safe, well-equipped and secure garages. This is especially true in cooperatives. If the premises adjacent to you are very poorly protected, it is through them that intruders can get into your garage. This risk factor is very serious.
• The specifics of the area, as well as the level of crime in it, play a big role. When a place is poorly lit, rarely visited, it is difficult to see from different sides, the likelihood of criminals appearing increases sharply. It is better to purchase a more expensive garage, but safe place, in a quiet area.
• Finally, having an expensive car next to you can be a negative factor. It happens that an elite car is stored in a garage, but it is well protected, closed, and has an alarm system. And then criminals can try to break into it through the next room. That is, the neighboring garage is under threat.

Be careful. To make your garage more secure, try to eliminate all risk factors and take additional safety measures.

We strengthen the garage

Now we will find out how to protect garages from opening, we will consider various options. We have already found out that metal structure must be welded from thick material. It is necessary to strengthen not only your garage, but also the neighboring ones. It is necessary to prevent undermining and lifting of the box. Now let's move on to the gate.

Gate protection

The weak link is the garage door. Unfortunately, quite often criminals resort to forceful opening of gates: they make jerks using cars, attaching a cable to the doors or gate handle. This method is quite effective, especially if the place is poorly visible and illuminated, and the area is deserted. To increase the level of safety, it is necessary to make the doors solid, without cracks or gaps.

Make additional stiffeners on metal gates Oh. This is a good way to strengthen them. The best option– made of iron with a thickness of at least 3 mm. The frame must also be strong. It is advisable to weld it from channel number 6, just like the box. An additional measure is to fasten the box with a reliable weld to the walls and beams of the garage.

Remember that attackers often press the gate using a crowbar. Here you need to eliminate the gap between the two swing gate leaves. Weld a strip of metal so that it is impossible to push the crowbar into the gap.

Loops

The vulnerability is often associated with loops. They are further strengthened by welding bolts. But this does not always help, since the bolt heads are cut off with a grinder or knocked off with a chisel.

Optimal modern solution- install internal hinges. In their design and structure, they resemble car hinges. Of course, they will be more difficult to install, but it is also extremely difficult for criminals to get to such loops.

Locks

Locks must be extremely secure. It is advisable to use combinations of several locks different types. The external lock protects the metal casing quite well. True, experienced criminals also get rid of casings by threading a crowbar into the shackle. The locking design with hidden rods is more reliable. They have a streamlined shape, which makes it difficult to throw on a chain.

Most effective solution- install one that will be securely closed from the outside. Experts also advise installing several locks, keeping a distance of 30 cm between them. Then, even if you try to break in, the load will be distributed. Be sure to ensure that the locks are well recessed and in no case protrude beyond the gate.

Electronic protection

It is most prudent to install an alarm system with remote control in the garage. Then, when a penetration or attempted break-in is detected, a squad will immediately go to the place. You won't have to run telephone wires because the radio link is now used. If you just want to scare away intruders, install a sound alarm: when someone breaks in, the siren will sound. Carefully mask the alarm switch.

Video: we provide reliable protection for the garage

Worth a look and useful materials on video. Here, car enthusiasts tell how to protect garages from being opened, show everything specific examples. For example, you can make reliable garage doors by equipping them with a special locking hatch. This will significantly improve the level of security.

You also need to pay attention to correct installation modern reliable locks for garage doors. IN next video explains in detail how this should be done.

If you follow the advice, act comprehensively, and do not leave any weak points in the structure’s protection, you will be able to ensure safety in your garage.

From the article you will learn how to strengthen swing and sectional garage doors to increase structural strength and the level of burglary protection. We will look at the most popular and effective ways. Tips and tricks will help you protect your car and other valuable property.

How to strengthen a garage door: increasing the protection of structures with swing doors

Before strengthening a garage door equipped with leaves swing type, reveal everything weak spots, which can be used by attackers.

List of most common problems:

1. loose connection of the valves to each other;
2. protruding loops for padlocks;
3. the presence of handles and other elements to which the cable can be tied;
4. hinges located outside, intended for hanging sashes;
5. weak locks;
6. sashes without stiffeners, made of thin sheets of steel;
7. no alarm.

Ideally, a garage door should be free from all of the above disadvantages. Next, we will talk about ways to strengthen hinges and sashes, as well as the nuances of choosing and installing locks.

How to strengthen the hinges of swing gates

There is only one way to strengthen the external hinges. Weld special metal rods onto them. This will make sawing much more difficult.

Important! This method is used only in cases where it is impossible to install the gate so that the hinges are inside the garage. If the attacker is armed with an acetylene cutter, strengthening will not help.

To prevent the gate from being removed from its hinges, weld metal pins or plates to the gates as shown in the photo below.

Photo No. 1: reinforcement of swing gates to protect them from being removed from the hinges

When the doors are closed, the metal plates move out to the sides and fit into the holes in the walls. In this case, the gate will not open and will not fall out even after cutting off the hinges.

How to strengthen swing gate leaves

Let's start with the fact that for maximum reliability swing gates must be made of steel sheets with a minimum thickness of 3 mm, and the frame and frame must be made of channels No. 6.

To strengthen the sashes, additional stiffening ribs are welded to them. For their manufacture they usually take:

How to further enhance the protection of swing gates from burglary

1. It is better to remove loops for padlocks, handles and other elements to which a cable can be tied, or install them on internal surfaces.
2. Make sure that the sashes fit together as closely as possible. If necessary, weld a metal plate onto one of them. A tight fit is also achieved by installing eccentric locks and vertical bolts.
3. For additional protection of the premises, you can install lattice doors behind the main gate, which will be locked to the person inside. the padlock. Weld a steel plate on the outside to hide the locking device from prying eyes. You will have to open the lock by touch.

Selection and installation features of locks for swing gates

When choosing locks, immediately ask the seller to show you models designed specifically for garages. Such locking devices are marked with the letter “G”. Lever and disc locks are optimal. Burglar resistance must be at least class 3.

Basic rules for installing locks.

• Mechanisms and fastening elements must not protrude beyond the plane of the gate from the outside.
• For fixation, use reliable bolts (thickness - 8 mm and above).

Important! Place 2-3 locking devices of different types at a distance of 30-40 cm from each other. Experts recommend additionally protecting locks with metal windows.

How to strengthen sectional doors

Sectional doors can be strengthened using steel profiles. The need to strengthen structures arises in three cases.

1. The gate is installed in a room where it is possible significant differences temperature or air humidity exceeds permissible values.
2. Sandwich panels are subject to constant high wind loads.
3. The entrance to the garage is located at sunny side(thermal deformations are possible).

Image No. 1: canvas sectional doors with amplifiers

If steel profiles were not included in the package, you will have to purchase them separately. Prices are at a more than acceptable level.

Important! If you order sectional doors with the possibility of remote control, do not skimp on electronics and ask whether the equipment is equipped with remote monitoring systems, protection against signal interception and encryption.

To monitor the condition of structures, connect the automation to the Internet and install the application on your smartphone. This way you can monitor your garage in real time.

The protection of sectional doors from burglary is also enhanced by installing secret locking mechanisms. This method of increasing security is best suited for manual models, since hidden locks are not associated with automation.

Garage Door Alarm

Installing a security system is a great way to protect both manual and automatic sectional garage doors from burglary. In Moscow, alarm systems connected to centralized surveillance consoles of private security agencies are popular. When an alarm is received, rapid response teams go to the sites.

You can also equip the gate with a “howler” alarm that makes loud sounds when unauthorized entry is attempted. Don't forget to install and mask the switch.

For any motorist, a garage is not just an additional room near the house, but a building element that serves to store an iron horse, and is also used as a storage room or workshop. Therefore, here, too, climatic conditions must be provided that will be comfortable for the car. And this may require garage door repair or insulation, since this part is vulnerable. There are simple troubleshooting methods. Knowing them, you can do all the work yourself.

Insulation of garage doors

To properly insulate gates, you must follow certain rules:

• pay attention not only to insulating the door leaf, but also to sealing joints and cracks using a material that is characterized high coefficient extensions;
• carefully select insulation whose thermal conductivity is higher than that of the garage walls;
• compliance with safety regulations;
• thickness thermal insulation material must be the same over the entire area of ​​the gate;
• carry out the process at positive temperatures.

Is it necessary to insulate and why?

As a rule, they are made of metal. Because of this, problems arise. IN winter time year they are prone to frostbite. This happens due to the fact that uneven frosting occurs around the perimeter of the garage, since only the gates are metal. After all, it is metal, not brick, that is the most heat-conducting element. Because of this, the gate condenses moisture from inside the garage, and when negative temperature air, this condensate turns into ice.

Condensation appears at any time of the year due to daily temperature fluctuations. And this threatens to create some problems:

1. Corrosion due to prolonged exposure to moisture. Uninsulated gates rust much faster, and this happens even if stainless steel was used for their manufacture.
2. Condensation settles on all metal objects located in the garage, including the car, which usually drives into a cold garage warm due to constant work. The garage is designed to preserve it, but in the absence of insulated gates, on the contrary, it contributes to its deterioration. In an unprepared garage, a car rots faster, and this, unfortunately, is not a myth.
3. The ice prevents the gate from being opened. Trying to do this quickly may cause damage.

There are many reasons to insulate your garage door as quickly as possible. But it needs to be done correctly.

Material selection

The first issue that needs to be resolved is the choice of thermal insulation material. Each of them has its own specifications, which can be both an advantage and a disadvantage. The table will help you familiarize yourself with them.

Table: insulation materials

Knowing these characteristics, you can form a holistic picture of each material, based on which you can make a choice:

1. Expanded polystyrene is not as resistant to fire, but the advantages are low thermal conductivity and high resistance to moisture.
2. Polyurethane foam allows you to perform insulation without seams, and it can be applied to an unprepared surface. This material is absolutely resistant to temperature changes, exposure chemicals, thereby ensuring the strength and durability of insulated gates. But for this pleasure you will have to pay a considerable amount.
3. Mineral wool does not burn. Since there is a high risk of sparks in a garage, it is worth considering using this material. However, when installing it, you need to take care of additional hydro- and vapor barrier.
4. Foam plastic almost does not conduct heat and has high moisture resistance, which is very important when insulating gates. And also, thanks to its low density, there will be no additional load on the gate. Polystyrene foam is absolutely safe for humans and environment. Moreover, he is quite available material and easy to process. Therefore, foam plastic is considered almost ideal for insulating metal garage doors.

There are other materials that are suitable for this purpose, for example liquid foam- penoizol.

Calculation of the amount of material

For high-quality insulation In advance, you need to carefully calculate the consumption of all the necessary materials. In addition to the selected insulation, you will also need facing material, which will be used to decorate the gate at the end of the work. It could be:

• lining;
• corrugated sheeting;
• Fiberboard or MDF;
• plywood (it is recommended to choose moisture-resistant);
• OSB boards ( perfect option, because it is high-strength, vapor-tight, easy to process, and cheap).

To calculate the quantity facing material you need to know the size of the gate. As a rule, when using OSB boards for insulation, two pieces are enough, since their standard dimensions are 125 * 250 cm.

For cladding you will need to install sheathing. It must be placed on the gate leaf. For this it is better to take wooden blocks minimum 4*2.5 cm. They need to be mounted around the perimeter of the canvas, and can be attached to metal corners. When calculating it general design dimensions must be taken into account load-bearing elements gate, foam boards(or other insulation), while the fastening step of the facing material must be at least 40 cm. The bars must first be treated with an antiseptic to prevent them from rotting.

To install the sheathing, you will also need galvanized self-tapping screws:

• for fastening to the side surface - 3.5*30 mm;
• for end mounting - 4.5*70 mm.

The length of the screw depends on whether the sheathing will be attached to metal corners or a pipe. In the second case, the length should be increased. To calculate their quantity, you need to make a drawing of the gate insulation on paper.

It is better to fasten OSB boards with screws with a press washer 32 mm long. The quantity is calculated in the same way.

For high-quality insulation of metal gates, you must not forget about anti-corrosion protection. A special primer is suitable for this. It must be applied to a degreased surface.

You can’t do without polyurethane foam, which is needed for attaching insulation boards to the gates and sealing cracks.

Tools

To ensure high-quality insulation of metal garage doors, you need a number of tools that almost every good owner has:

1. Electric drill.
2. Drill. It is necessary to take care in advance of the availability of drills for working with wood and metal (if the sheathing is wooden).
3. Screwdrivers of various sections. Can be replaced with a screwdriver.
4. Wood saw. If so, then a jigsaw. It will speed up the work.
5. A metal brush with metal bristles or an appropriate drill attachment.

In addition to these tools, you may need others, for example:

• brush or roller for applying antiseptic;
• hammer;
• core (used for marking drill holes);
• tape measure or meter ruler;
• square;
• construction knife;
• sandpaper;
• clamps (needed to secure elements).

Step-by-step instruction

Once the material has been selected and calculated, the tool has been prepared, you can begin directly insulating the garage door. All work takes place in several stages (in the case of foam insulation):

• Preparatory work. This stage should never be skipped, since it largely depends on the quality of the thermal insulation. If there is rust on the canvas, you need to get rid of it using a special attachment on a drill. It is recommended to walk over the entire surface of the gate sandpaper, and then with a degreaser. Next, an anti-corrosion primer is applied in two layers (the second layer can be applied only after the first has dried thoroughly). Now is the time to install the waterproofing layer. Suitable for this bitumen mastic, vapor barrier membrane, isolon.
• Installation of sheathing. Install the sheathing on the inner surface of the gate. It can be metal or wood. It must be fastened to the base of the metal sheet with self-tapping screws or self-tapping screws. Make fastenings according to the drawing, and for this you need to make markings, and then drill holes without overheating the drill. The bars must all be solid, it is recommended to tighten them with clamps, and then drill them with a thin drill.

If there is a problem with attaching the lower horizontal beam to the frame or gate, then it can only be attached at the end. If it is possible to remove the gate, then this must be done in order to reach the frame with a tool.

If desired, the slabs can be painted in your favorite color, however, even without this, the main goal of insulation will be achieved.

Do-it-yourself garage repair: how and why to do it

Timely execution repair work- a necessity, since cold air can penetrate through the gate, which adversely affects technical condition car. Fortunately, you can carry out routine repairs yourself.

How to raise the gate

Reasons why it is required of this type There may be several repairs. Most often, it is necessary to raise the gate when it is impossible to open it not only in winter due to icing, but also in summer. The most in a simple way The solution to this problem is to trim the gate and then concrete the driveway. However, it is better to carry out a full repair so as not to reduce the dimensions of the structure.

Gate lifting steps:

1. Dismantle them and release the frame. Before removing the gate from its hinges, it is recommended to wash the mortar between the bricks.
2. Remove several rows of bricks from the top of the garage opening. Instead of bricks, lay a channel or a high-strength corner that is fixed anchor bolts. This will save the gate structure from further destruction.
3. In the lower area, raise the fill slightly. You can seal the gap between the gate and the floor in another way, for example, by concreting. You can also make a small threshold. Regardless of the method of eliminating the gap, you need to ensure that the slope is directed towards the street, otherwise excess moisture in the garage cannot be avoided, especially during heavy rain.

How to strengthen the frame on the wall

One of the problems that can affect the ease of use of the garage is the door frame coming away from the wall. Conduct this type You can do the repairs yourself. This is done as follows:

1. Remove the old gate.
2. Weld a metal belt to the gate from the inside.
3. Replace old hinges with new ones.
4. In places where the frame is attached to the wall, it is recommended to install metal corners and fittings.
5. Install the gate, observing all the rules.

It is necessary to carefully strengthen the gate frame to the wall, since this is one of the vulnerable points of the garage.

How to replace a gate

In some cases, a complete replacement of the gate is necessary. This can happen for many reasons, such as when the structure has become unusable due to rust and rot. The gate replacement process only takes a few hours. During this time they are carried out following works(after dismantling the old gate):

1. Frame installation. It will give the gate the necessary rigidity and allow the doors to move easily. First, the outer and inner parts of the frame are installed to the opening. For this, metal pins with a length of 150 to 180 mm are used (it is recommended that their ends be processed with a welding machine, sanded and painted).
2. Provide additional fastening of the gate with iron jumpers. The distance between them should be from 2 to 4 cm.
3. Fixing the sashes on hinges.

How to correct misalignment and adjust correctly

Problems arise when the geometry of the gate is violated. You can solve it depending on the cause of the problem:

Repairing and insulating garage doors is a painstaking task; not every owner wants to do everything themselves. However, if it is not possible to invite an experienced specialist, then these tips will help you do everything quickly and efficiently.

The gate is the face of the garage. The quality of their insulation determines the microclimate in the room. How well they function determines whether you can open the garage and drive your car out of it at any time.

Most car owners can insulate garage doors and carry out routine repairs on their own. The appropriate tools and materials are available in every private household.

Insulation of garage doors

For many car owners, a garage is more than a place to park a car. Here you can equip a small workshop, make a warehouse for useful things, and finally spend time in the company of friends.

Needs maintenance in the garage optimal temperature both in winter and summer. According to building regulations, in a heated room this figure is +5 degrees. This will allow you not to warm up the car before starting and avoid the accumulation of moisture in hidden cavities.

Do I need to insulate garage doors (with an automatic mechanism, swing doors, overhead doors, sectional doors, swing doors, etc.)?

To determine whether your garage door needs to be insulated, just look at the thermal image. She shows that most of heat leaves the room through uninsulated gates.

This factor is especially important for owners of built-in garages. Often the heating of such a room is included in the general house system. And heat loss through uninsulated gates will affect the entire house as a whole. Heat costs will increase.

Let's consider the types of gate structures and evaluate the need and possibility of their insulation.

1. Roller shutter structures consisting of individual aluminum slats. Some models have polyurethane foam inside. The fabric itself is wound on a shaft located above doorway. In view of design features insulation is not possible.
2. Sectional doors. It is based on sandwich panels filled with polyurethane foam. Additional insulation not required, however, you can stick foam on inner part sections.
3. Swing gates. The most common design, consisting of two sashes hung on welded hinges. In the very simple version consist of a metal sheet welded to steel frame. It is advisable to insulate such a structure during the construction stage, however, this can be done independently, after installing the gate.
4. The lift-and-turn design consists of one leaf. You can make it yourself or purchase products from famous manufacturer. Factory fabric is a panel made of durable sheet steel and insulation, which is often polyurethane foam. A thickness of 45 millimeters is enough to prevent heat loss. Homemade gates must be carefully insulated.

Such gates do not require additional insulation

Selecting material for insulation (foam plastic, penoizol, etc.)

Picking up high-quality insulation There are a few things to keep in mind. So, it’s not suitable for insulating garage doors. mineral wool and other porous materials. Most often, the thickness of the walls of a garage is much less than that of a residential building. Often, corrugated sheeting or a similar product is used as the main building material. When using porous insulation, a dew point forms in it. As water accumulates in the pores, its density and thermal conductivity increase. Ultimately, this minimizes the effectiveness of insulation.

Among the most suitable materials are:

1. Styrofoam. Inexpensive insulation, obtained by dry heat treatment of polystyrene granules.
2. Expanded polystyrene. It is also developed on the basis of polystyrene, however, using melting. There are several varieties: extruded, pressed, unpressed. The main advantages are lightness, durability and ease of processing. The disadvantage is poor vapor permeability, as a result of which increased demands are placed on the insulated room in terms of ventilation.
3. Penoizol, which contains elements such as orthophosphoric acid, resins and carbide. Strong and durable material, resistant to combustion. However, low-quality penoizol can release toxic formaldehyde when burned.
4. Polyurethane foam is a sprayed insulation material with excellent heat saving properties. The material is actively used in various industries industry.

Inexpensive insulation for gates and walls

When insulating garage door it makes sense to choose between expanded polystyrene and polystyrene foam. The materials have the following differences:

• Strength. Polystyrene foam is a combination of individual elements. Expanded polystyrene is a single substance. The bending strength of the latter is several times higher.
• Permeability. Standard foam has voids that liquids can penetrate. Water absorption of polystyrene foam is much greater.
• Price. Polystyrene foam is noticeably cheaper.

If resistance to heavy loads is not critical for you and you want to insulate your garage door with a simple and inexpensive material, your choice is polystyrene foam. In other cases - polystyrene foam.

There is no point in saving on insulation. Otherwise, the effectiveness of the work performed will be zero. The thickness of the layer depends on the climate in which the garage is located. So, in the European part of the country the weather is moderate, not too cold, however, sometimes the temperature reaches minus 25 degrees. In such conditions, the following thickness of insulation is sufficient:

• Polyurethane foam: 70 mm
• Extruded polystyrene foam: 80 mm
• Foam: 100 mm

Tools and materials

Before installation, you should carefully measure the garage door and calculate the amount of materials that will be required for insulation and cladding.

There are many facing materials on sale:

For cladding garage doors, 10 mm OSB-3 or OSB-4 boards, designed for rooms with high humidity. The standard product size is 1250*2500 mm. Two slabs are enough for finishing.

The cladding is attached to the sheathing. For this purpose, small wooden blocks of 40*40 mm are used, attached to the supporting part of the gate structure. The boards are installed around the perimeter and on the canvas area.

The dimensions of the insulation may vary. They are selected based on the location of the sheathing: you should avoid a large number of scraps and strive to ensure that entire sheets of polystyrene foam are located between the individual bars.

In addition to materials, for high-quality insulation of gates you will need a set household tools, which most home craftsmen have:

How to insulate with your own hands: step-by-step instructions

The simplest way to insulate a gate is to lay a sheet of insulation directly between the frame posts, without any preparatory work. After which a suitable finishing material. However, the resulting design will be short-lived and will not preserve sufficient quantity heat in the room.

Professional insulation of garage doors occurs in several stages:

Preparation

First of all, you need to treat the bars with an antiseptic in one or two layers. Remember individual means protection: wood impregnations contain aggressive chemicals.

After processing, the bars must dry. At this time, you need to prepare the gate for insulation. The surface of the canvas is carefully inspected, and if rust is detected, it is cleaned down to the metal with a stiff brush or drill attachment. If there is peeling paint, it must also be cleaned off. The resulting surface should not have rust spots and pollution. After this, the canvases are sequentially treated with a solvent and a primer.

After drying, the surface of the garage door needs to be waterproofed. If standard polystyrene foam is used as insulation, this operation is mandatory; when using extruded polystyrene foam, it can be skipped.

Waterproofing can be done using various methods:

1. By gluing isolon - a two-millimeter foil film made of polyethylene foam.
2. By gluing a membrane with a vapor barrier function.
3. Treatment with bitumen mastic.

Installation of sheathing

First of all, the beams are cut required size. Places where ventilation holes and locks are located are circumscribed and will not be insulated.

In the places where the block will be attached to the frame, you need to drill holes with a 4 mm drill. Optimal step- 20–25 centimeters. If you need the screw head to be flush with the canvas, you can make small indentations. An eight-millimeter drill is used for this. It is important not to overdo it and remove only the amount of metal that is necessary to hide the head.

Before fastening, the bars are pulled to the frame using clamps. To prevent the wood from cracking, you can additionally drill holes equal to the depth of the screw. A 2mm drill is used for this.

All bars located around the perimeter of the frame are installed in a similar way. Additional crossbars are attached with self-tapping screws to the end in increments of 20–25 centimeters.

Sheets of insulation will be placed in these cells

Installation of insulation

The space between the sheathing elements is filled with foam plastic or expanded polystyrene. For this:

1. The size of each cell is measured.
2. The insulation is cut according to the obtained dimensions. To do this you will need a construction knife and a ruler. On each side you need to leave a small margin - about 2-3 millimeters. This is necessary so that the elastic foam fits more tightly between the sheathing boards.
3. The insulation is fixed in the cells.

There are several ways to attach foam between the bars:

• Using facing materials. In this case, the foam itself is not attached, but is pressed against OSB boards.
• Using "liquid nails".
• Using polyurethane foam. The material has excellent adhesion. If you choose this method, the surface must be moistened before applying the foam: hardening occurs only through direct contact with the liquid.

After installing the insulation, the remaining joints are sealed polyurethane foam. After it dries, the excess is cut off with a knife.

In this case, the gates are insulated with foam plastic

Gate cladding

IN finishing After insulation of garage doors, OSB boards are often used. The products cover the sheathing and insulation, making the doors more presentable.

The main condition is either the absence of joints or their location on the bars. Therefore, before cutting the sheets, it is necessary to measure all surfaces.

For cutting, you can use either a regular wood hacksaw or a jigsaw, or a powerful circular saw. The finished sheets are tried on at the site of future installation. If necessary, holes for locks are cut in them, ventilation holes etc. After this, you can attach the cladding.

The standard fastening pitch is 12–15 centimeters on racks located around the perimeter, and about 20 centimeters on transverse strips. To avoid cracking the wood, you can drill small holes with a small diameter bit before tightening the screws.

OSB boards can be used as facing material

Repair work: how to fix problems

A quality garage door can last for decades. However, with such a long-term operation, it is inevitable that a number of works on their routine maintenance and repairs. Most operations can be performed independently.

How to Raise a Garage Door That's Sagging

The main reasons why it may be necessary to change the geometry of the gate structure are:

1. General metal fatigue. Usually occurs after prolonged use.
2. Loop subsidence.
3. Possible deformations associated with poor-quality installation.
4. Doorway subsidence.
5. Other factors - for example, in hot weather sunny weather deformation of the structure under the influence of high temperature is possible.

There are other reasons why the gate will need to be raised. The most common is purchasing new car, which is a little short in height.

Each problem requires an individual approach to correcting the geometry of the gate. Many methods are available for independent work using everyday tools.

Elimination of sagging loops. To lift the hinges on the gate leaf, a special spacer washer is used. The work is as follows:

• The sash returns to its place. Using this method, you can straighten minor distortions of the gate leaves, raise the gate and make the structure move more freely. Important: the alloy from which the ball or washer is made must be harder than that used to create the loop.
• A washer of a given thickness is placed on the axis of the lower loop. If a suitable part cannot be found, a metal ball of the required diameter is inserted into the loop hole.
• The canvas is removed.

If you need to change the distance from the ground to the bottom of the sash, you can simply cut off part of the structure with a grinder and attach a rubber strip on top. This will help hide the gap that has formed. This method can be used if the bottom beam is located beyond the edges of the sheathing. If the crossbar is located close to the ground, you need to do the following:

• Carefully cut off the horizontal crossbar with a grinder.
• Trim the gate leaf to the required height.
• if necessary, attach a small rubber strip to the gate, the width equal to the distance from the bottom of the gate to the ground.
• weld the horizontal bar to the frame in a new place.

Sometimes the sashes become warped due to the deformation of the opening. In this case, you will have to either raise the opening itself, or correct the distortion on the sash itself. To slightly raise part of the structure without touching the frame, you need to cut the horizontal beam near the place of deformation, cut off 5–7 millimeters with a grinder, lift part of the sash, press vertical beam and weld. This method is used for small gaps. For reinforcement, a metal strip is attached to the welding site, since the risk of residual deformation remains.

If other methods do not help, you will need to increase the height of the gate opening itself. In practice, such work is associated with certain difficulties. It is necessary to install temporary supports and clarify whether reinforcement passes inside the masonry. If you do not take into account all the nuances, there is a possibility of wall destruction or roof collapse.

Raising the level of the gateway is quite complicated. Additional equipment and bricklaying skills required

Correct strengthening and protection

For installation, durable metal pins up to 20 centimeters long are used. Once installed, they are cut and sanded to ensure smooth opening and closing of the sashes. The gate is hung on the frame.

Additional reinforcement of your garage door makes sense if you are the owner of a permanent concrete building. To strengthen the walls next to the structure, you can use a metal frame welded from corners and welded with mesh. It can be installed both at the construction stage of the building and subsequently, on the inside of the room.

Strong metal rods welded to the hinges make it much more difficult for an intruder to saw through. Additionally, nuts and bolts can be welded on the back side of the blades.

Placement of stiffeners using the example of swing gates with a separate door

To press the sashes more tightly against each other, you can use an eccentric latch. A wide strip of metal is welded onto one of the canvases, thanks to which an attacker will not be able to use a crowbar or similar tool.

To strengthen the sashes themselves, horizontal and vertical stiffeners are welded to the frame. These are transverse metal posts located at some distance from the edges of the canvas. Their number depends on what degree of rigidity is needed. The length of the crossbar is determined based on the dimensions of the canvas as the distance between the opposite posts of the frame.

If one of the doors has a door, vertical stiffening ribs are welded on both sides of it, otherwise deformation of the leaf is possible. If there is no door, horizontal or vertical crossbars are welded to the frame anywhere, most often in the center of the structure.

Replacement

Garage door replacement may be necessary for a variety of reasons. The old structure may have become rusty or warped. Or have you purchased a new gate? best quality or registration.

The first stage is the dismantling of the old structure. Before this, it is necessary to clarify whether there are additional “inserts” from thieves, such as welded to the frame above door hinges bolts, pieces of reinforcement or other similar elements. If they exist, they need to be dismantled.

The easiest way to dismantle metal swing gates. It is enough to open both doors and remove the panels from their hinges. After this, if necessary, remove the hinges themselves (with a sledgehammer, grinder, etc.) and you can install a new gate.

If the hinges become deformed or corroded, it is better to replace them.

To install the canvases into an existing frame, you only need to carry out necessary measurements, weld the hinges and hang the new gate on them.

If the gate is replaced along with the frame, old frame needs to be dismantled. It is better to entrust this work professional builders, as damage to the masonry is possible. After dismantling, a new supporting frame is installed, leveled and attached to the opening with long self-tapping screws. For conventional design 4–6 pieces per side are enough; when installing a reinforced frame, the number of dowels reaches 10.

If garage doors are installed without a frame, on poles, their replacement occurs in several stages:

1. Opening the doors all the way.
2. Removing the canvases from the hinges.
3. Removing hinges (if necessary).
4. Cleaning surfaces from rust, eliminating possible damage. Treatment with anti-corrosion compounds.
5. Welding new hinges.
6. Hanging and adjusting sashes.

Adjustment in case of misalignment

Skewed gates are a problem in older garages. At some point, the doors stop closing and cling to each other and to the ground. Among the main reasons for such malfunctions are the following:

1. Poor quality welding when installing the gate.
2. Subsidence of the soil, the presence of trees nearby, whose roots can swell the foundation.
3. Material corrosion.

As a result of the problems described above, the gate leaves sag and become deformed. The load on the hinges and the opening mechanism increases, as a result of which the gate stops opening.

To fix the problem and prevent similar situations from occurring in the future, you must perform the following operations:

Additional stiffening ribs are installed around the perimeter. These are transverse metal crossbars that strengthen the structure. Their installation proceeds as follows:

1. From profile pipe, fittings or other suitable building materials, blanks are cut. The size of each corresponds to the distance between the opposite frame posts. Stiffening ribs can be horizontal or vertical; therefore, before making them, you need to measure the distance between the horizontal or vertical crossbars of the frame.
2. The workpiece is placed on the canvas and adjusted according to the level and construction angle. Its ends should be adjacent to the frame posts or a few millimeters behind them.
3. Stiffening ribs are welded using welding machine to the frame. They can be attached to the canvas using standard metal screws.

During long-term and active use of garage doors, it is necessary to monitor the position of the hinges, adjust them if necessary, and replace them in case of significant wear.

Garage doors must open, close and allow vehicles to pass through without hindrance.

At self-mounting hinges to swing gates and subsequent adjustment, several nuances must be taken into account:

1. The weld seam that is formed when welding the loop must be directed exclusively upward.
2. Welding occurs with small tacks, twice on each side alternately.
3. All elements are welded flush to the rectangular garage door post.
4. Before work, it is recommended to make a small backing for the bottom of the loop. Its length is half fastening element. The top of the substrate is grabbed from the end.
5. Before welding the gate hinges from the inside, you need to check how easily the doors open and close. If the gate does not operate correctly, it is additionally processed by welding from the outside.
6. Before the gate is finally secured, the doors are closed. To avoid sagging, a small stand is placed under the middle of each sash.

The gates open only some time after the end of work. This is necessary for the loops to cool down. When heated, the metal is very fragile and subject to deformation. If you overload the structure too early, all the work will have to start again.

If your overhead gate is jammed, the reason is in the opening system. In the simplest case, it is enough to lubricate the roller mechanism with oil to ensure the best sliding of the door along the guides. It is also possible that individual parts, such as the shaft or spring, may be damaged. Faulty elements are replaced with new ones that are identical in functionality.
