Install plastic windows in the apartment. At what stage of construction should windows be installed? Irreversible consequences of “amateur activity” in installing windows

People have been building wooden houses since ancient times. But not everyone knows what a difficult task it is to build a wooden house. There are many subtleties here. And one of the most important issues is installation in wooden house doors and windows.

First of all, you need to know: if the house is not built from laminated veneer lumber or dried wood, doors and windows cannot be installed in it right away.

Windows in a log house can be installed approximately six months after the walls of the house are built. The reason here, first of all, is the shrinkage of the log house. The thing is that when it dries, the shape and size of the wood changes. If you install windows and doors in just assembled log house, everything may end up with the fact that after a while the house will literally crush the windows and push out the doors.

Shrinkage of a house made of undried wood can generally last up to 7–8 years. Experts believe that windows and doors can be installed in a house in about six months, since the main shrinkage occurs during this period.

However, we must remember: six months is average term. U different houses there may be different shrinkage. This largely depends on what time of year the trees were cut down, the conditions and quality of drying, etc.

All wooden houses can be divided into several categories. It will take 10 to 12 months for the frame of a house built from freshly cut logs to settle. If the house is built from processed profiled timber, the period is reduced to 3 – 4 months. A house built from dried timber practically does not need sludge. It is quite enough to wait 2 - 3 weeks. During this time, under their own weight, the logs will press closer together. After this, you can install windows and doors in the house, carry out finishing premises and move into new house. In order for the house to shrink faster, the house must have good ventilation.

Many people believe that when a house shrinks, its frame may collapse. To prevent this from happening, special notches are made at the joints of the logs. In the presence of such knots, the joints do not lose their density during shrinkage of the house.

From everything that has been said, one conclusion can be drawn: the installation time of doors and windows in a log house depends on the type of house itself. If, when building a house, you follow everything simple rules, which were listed above, you will not have any problems, and your home will serve you long years, delighting you and your loved ones.

No complicated operations when installing a plastic window with my own hands not required. You do not need to have special skills or special expensive equipment for this. The installation technology is simple and consists of cleaning the opening and installing the window. Total installation plastic windows DIY it will only take a couple of hours. Agree, this is not too much.

But at the same time, you will save family budget, for a rather large amount of money on one window for not using the services of specialists. Sometimes the price for installation is calculated as a percentage of the cost of a new window and in some companies amounts to ten to forty percent of the cost of the windows.

Tool for installing plastic windows

So, what tool will you need to install plastic windows on a building under construction, be it Vacation home or cottage:

• level;
• screwdriver;
• gun for easier application polyurethane foam;

polyurethane foam is calculated 1 - 3 cylinders per 1 standard window

• perforator;
• set of hexagons;
• gun for applying silicone;
• stationery knife;
• jigsaw;
• roulette;
• pencil.

Cleaning the opening for a plastic window

Before proceeding with installation, it is necessary to clean the opening for the plastic window.

When cleaning the opening for a plastic window, deep depressions or all kinds of delaminations that arose during the construction of the house are removed; it is better to restore the wall and only then continue further work on installing windows.

Installation of plastic windows and frame alignment

Installation of plastic windows consists of certain actions:

• We make marks with a pencil on the window frame in the places where the fastening will take place (there are 4 of them every 70 cm). The distance from the corner of the window frame of the outer fastener is usually left within 5-15 cm. If your window comes with a stand profile, then you don’t have to fasten the frame from below.
• The next step when installing a plastic window is to attach all fasteners to the window frame. Fastening element(self-tapping screw, diameter 4 mm) is fixed in metal, which is located inside the frame (bent channel). Self-tapping screw, has a drill at the end. If the windows are large, then you will need screws with a diameter of 12 mm. You can also use special anchor plates as fastening elements.
• IN window opening We make recesses in the places where the fasteners will be attached. To perform this action, you need to insert the frame with fasteners already attached to its surface into the prepared window opening. Where the fasteners will be attached to the opening, we hollow out recesses according to the fixed size of the fasteners and approximately to a depth of 4 cm. In these places we will recess the fastener elements. We do this so that there are no problems later when finishing the slopes.

If the window does not have a mounting strip, then when inserting it into the opening, it must be raised in advance to a certain height of the window sill. To do this, place pieces of foam plastic or blocks of wood under the frame. If the window has mounting strip, then this procedure does not need to be done. There is no need to attach the mounting strip to the frame; it is usually supplied already attached.

• Leveling the frame involves a number of steps. To do this, in certain places under the frame we place, for example, wooden wedges (bars established size), which must be located strictly under the transverse parts of the window frame. You need to insert them like this: first, the two lower ones and, accordingly, the upper ones into the horizon. The longest thing to do when leveling the eye is to align the wedges. As a result of the work, your frame should be level, both horizontally and vertically. We check the work with a level. This type It's easier to do the work together. We can finally secure the window in the window opening with anchors or dowels. For fastening to hollow brick, shell rock and foam concrete, it is better to use anchors with a diameter of 6-8 mm. We attach the ebb with metal screws (diameter 4 mm) to the window frame.
• Pre-adjustment window fittings. Window adjustments are made in the hinges using hexagons. During these actions, the sash should move freely. Sometimes, when closing/opening a window, it clicks in the places where the locking hardware is installed. The fix is ​​simple: unscrew the screw on this element and move it 0.5-1 centimeter higher or lower.
• We foam all the gaps that have formed between the window opening and the frame.

Installation of double-glazed windows into the frame

Installation of a double-glazed window into a frame consists of the following steps:

1. We check the presence of linings under the glass unit. If the case is a blind frame, then there should be 2-4 of them on both sides.
2. Installing a double-glazed window into a frame requires experience; if not, then it is better to do the installation together. We place the glass unit on the pads (holding it at a slight angle towards you). Then, when you give it a vertical position, so that it slightly presses the receiving rubber on the frame.
3. Next, we press the package along the plane where it joins the frame, and install glazing beads, first vertical. We press strongly from the ends of the bead, as if inserting it into the center. If you can’t drive it in by hand, tap it with a mallet.

Installation of plastic window sills

Often installation plastic window sills starts with cutting them off, because as they go standard width and length, that is, with a certain margin. To do this you will need an electric jigsaw, grinder or saw with small teeth.

1. When installing a plastic window, we cut the window sill to the required level. Then we push the window sill to the support profile. Next, we level our window sill; to do this, we place wooden blocks, pieces of brick, or laminate cuttings under it.
2. We are in the process of leveling the window sill. It is better to install the plugs so that they fit completely into the wall. And it is better to glue them additionally with super glue, since silicone and acrylic do not glue them.

As a result, your window sill should be level in two horizontal directions and not sag in any place (check by pressing with your hand). Sometimes the window sill is mounted with a slight slope, so that the condensation that forms on the window does not flow all under the window. And if you decide to make such a slope, then make it small, only about 3 degrees.

The next step will be to blow foam into the cavity under the window sill. After this, we evenly load the window sill with some weight (you can put bottles of water) over the entire surface for approximately twelve hours. If this procedure is not followed, the foam will simply bend it upward.

A day after foaming, we remove the remaining foam that came out of the cavity under the window sill in the usual way. stationery knife. Sometimes, due to the unevenness of the window sill, after its installation there is a small gap between window frame and the top of the window sill. In this case, we fill it with silicone. Remove any remaining silicone immediately with a rag.

Consider the fact that silicone turns black over time due to fungus and makes it unsightly. appearance windows and window sills, therefore it is better to prevent such a gap in advance. This can be done by screwing Z-shaped plates made of galvanized steel to the window sill profile before installing it. Also, such plates will come to the rescue when leveling the window sill.

Adjusting plastic window fittings

The final phase of the work on installing a plastic window in a house under construction, which is done only after the covering material and foam has completely dried, is the adjustment of the plastic window fittings (installation and adjustment of locking elements). When the window sashes close and open freely and there is nothing fastened anywhere, this means that you have successfully completed the adjustment of the plastic window fittings.

Better to delete protective film with the company logo right away. It will not add beauty to the window, and in the future it will only turn into almost indelible dirt.

That's it, the whole process of installing a plastic window in a house under construction on your own has been completed, everything, as you have seen, is not as difficult as it seems to someone.

Window production and installation technologies are improving every year. But there is another significant factor that affects the durability and reliability of windows: when they were installed.

General rules. Ideally, it is better to install any window after performing wet finishing work inside the house, before finishing the facade. Installing windows before insulating the house will allow for quality work external finishing slopes and the walls themselves. The ideal sequence is as follows: wet work inside (without finishing slopes); window installation; finishing of slopes; then wet work on the facade.

When to install windows during the construction phase?

Wooden windows. Wet construction works(plastering, pouring screeds) create increased humidity in the room and can cause deformation wooden structures. A special one will not protect them either. acrylic paint(even if manufacturers say otherwise). In addition, moisture evaporating from the surface of finishing materials is chemically aggressive, which is also not good for the wood. Conclusion: you can install wooden windows only when the “wet” work is completed and the room is dried and well ventilated. If the windows need to be installed quickly, but it is impossible to comply with these rules, it is better to replace wet finishing dry (for example, drywall).

Plastic windows. You can install plastic windows before carrying out wet work. And if it happens in autumn or winter, this is the only possible variant. The main thing is to ensure good ventilation and a temperature above “+5” in the room, so that excess moisture does not form or accumulate inside the structure.

We focus on the facade. If the walls are single-layer, windows can be installed both before and after finishing the facade. Although the first option is preferable: you can more carefully trace the connection of the elements and secure them more accurately and reliably. Otherwise, it all depends on what you prefer: protect the windows from plaster or apply a second, cosmetic, layer to the facade after installing the windows. Windows are installed in double-layer walls before finishing with insulation. Its slabs adjacent to the windows are placed so that in the corners of the openings their joints do not coincide with each other. The corners of the slopes are reinforced with reinforcing mesh and corners. 2-3 cm of insulation is applied to window box. If the windows are installed after facing with insulation, some of the work will have to be done again.

When to install windows during renovation?

Before plastering. As already mentioned, at this stage you can install a plastic window - it’s better to wait with a wooden one. Before starting work, the windows and the entire structure are covered with film and first the slopes and corners of the openings are plastered, and then the walls. If renovations take place in the fall, windows protected with film are left open to allow moisture to escape.

After plastering. The walls are finished with plaster without touching the slopes, and after installing the window and the foam has dried, they are also plastered. If it is decided to finish the room with plasterboard, the same team that does the cladding can put the slopes in order.

Is it possible to install windows in winter?

Pros. Usually in winter windows are sold at a significant discount. In addition, in winter, all defects and installation errors, if any, are immediately detected. For example, if the installation seams are poorly insulated, all the cracks, and therefore drafts, are immediately noticeable, and in the summer they are easy to miss.

Minuses. Savings on windows can evaporate during installation if special frost-resistant materials, thermal barriers, etc. are required. Wooden windows better in winter do not mount at all. In principle, it is possible to install plastic windows, but only if the air temperature is not lower than “-5”, even if the polyurethane foam and sealants are designed for more low temperatures. The most resistant polyurethane foam does not “adhere” to the wall in cold weather and takes longer to dry, and PVC becomes brittle: mechanical stress can cause cracks and chips.

PVC windows make their choice both complex and simple. The simplicity lies in the fact that the wide the lineup allows you to select a suitable sample for the exterior of the house and its interior design. However, when purchasing, you may encounter difficulties: what to focus on when choosing? Who should be entrusted with the work so that the installation of plastic windows is of high quality and the structures last a long time and do not lose their beauty?

Consequences incorrect installation plastic windows can be unpleasant. In case of errors during glazing, the properties of PVC structures for heat conservation, protection from noise and dust may be lost. Work carried out incorrectly will lead to the formation of condensation, drafts, cracks on slopes, dampness, and the formation of fungus. In addition, a frame fixed skewed can create excess stress, which disables the locking mechanisms.

Self-assembly of a heavy structure without experience and special knowledge complicated and time consuming. To avoid troubles, it is better to order a service from experienced specialists.

Installation technology

Once you have decided how much it costs to install a window, you begin preparing the openings and premises for installation and finishing work.

• Dismantling of old structures. The standard dismantling option involves the destruction of old wooden frames. However, if necessary, dismantling can be done using gentle technology, after which the frames are kept intact and can be reused. The need for careful dismantling must be discussed in advance with the surveyor and manager at the stage of concluding the contract.
• Installation of windows. All installation work are carried out on the basis of GOST standards and in accordance with the specifics of profile systems. The window is leveled in the opening, secured with anchors or anchor plates and foamed around the perimeter. The foam seam must be sealed using vapor and waterproofing tapes, as well as PSUL tapes.
• Installation of window sill, ebb and mosquito net. The window sill is attached to a special support profile located under the window and carefully foamed. The ebb is screwed on from the street side using self-tapping screws.
• Slope finishing — The final stage. As finishing material We use warm plastic sandwich panels that fit perfectly with a PVC window block and provide excellent thermal insulation and protection of slopes from condensation.

A visible indicator that the installation of plastic windows was carried out correctly is the absence of any gaps or airflow in the assembly seam. At the end, the fittings are carefully adjusted and the closing tightness of the window sashes is tested.

During the process of building a house, many owners have a question about when to install windows. It is important to know that designs from natural wood installed after completion of interior finishing work such as screeding ceilings and plastering.

Before installation begins, the building must dry out a little, since high humidity air can cause swelling natural material and its cracking, as well as damage to the paintwork.

You can reduce air humidity by using gypsum board to decorate walls instead of plastering. In this case, the installation of the window structure can be carried out after screeding the walls and before finishing with gypsum board.

If you prefer plastic windows for your home, they can be installed both after and before finishing, since PVC construction is not susceptible to moisture. However, it is important to remember that if the walls are finished with plasterboard, the windows must be installed before using it, since the material is not moisture resistant.

Carrying out work in winter: basic details

Basic construction processes: laying the foundation, erecting walls, organizing the roof occurs during the warm period of the year. In autumn and winter it is time for interior finishing work. After installation metal-plastic windows needs to be started in the house heating system. In winter, it is recommended to use plasterboard sheets for wall decoration. The choice of this material does not greatly affect the level of humidity in the room, but will significantly speed up the repair work.

If the owners plan to install windows made of natural wood, dry plaster is used for finishing work to avoid swelling of the frames.

Recipe for success: correct microclimate in a room under renovation

The speed and quality of work largely depend on humidity and temperature. In houses where plastic windows are installed, it is necessary to improve the system natural ventilation. To do this, the windows are left slightly open, and ventilation ducts fans are installed.

It is also necessary to control the temperature. Until the screed and plaster are completely dry, the value on the thermometer should not fall below +5°C. As an alternative to traditional concrete screed You can partially use dry prefabricated. This choice will speed up the finishing work by reducing the amount of construction moisture.

We carry out finishing work in the summer

Interior decoration is an important and time-consuming process. Before starting repairs, it is advisable to complete the installation of plastic windows. Especially if the work is planned for the spring.

Window installation involves several stages. Upon completion of installation, repairs and leveling of slopes are carried out. Then they begin to treat the walls with cement mortar.

Installation of wooden windows should be postponed until the interior work is completed.

It is important to remember that a draft causes the wallpaper to peel off and causes the paint to “swell.” You can protect the room from air penetration using film. It is enough to fix it on the window opening.

The slopes must dry after finishing work. Therefore on initial stage, the solution should only be applied to walls. Wooden windows are installed last.

At the final stage you should plaster window slopes. Masters also use alternative method cladding - finishing them with plasterboard.

On walls that are not insulated in any way, the facade can be plastered both before and after installing windows. However, it is still recommended to carry out the work after the windows are installed. This will allow you to perform all subsequent tasks faster and more efficiently. Finishing work. After installing the windows, slopes and external sills can be installed immediately. These works make it possible to avoid further alterations to the façade. If the plaster was applied before installing the windows, then the subsequent plastering of the facade will be very different.

If the plans include the organization of two-layer walls, then initially they carry out
installing windows, and then laying insulation and plastering the facade. In addition, this order of installation allows for better finishing work.
external slopes.

So that after insulating the facade it is possible to apply plaster, slabs
apply 2-3 cm to the window opening. It should not be allowed to be in the corners
windows formed joints from insulation boards. Therefore, the slabs are cut, giving them
"G" shape. And then they attach it with a cutout in the corner of the window.

During the period of plastering the facades, specialists cover the windows with film, which is secured with adhesive tape. Upon completion of work it is removed. It is not recommended to secure the film with masking tape, since after removing it, marks will remain on the window.

Construction installation rules

When ordering windows, you must invite a company specialist who will accurately measure the dimensions of the future structure.

The product is installed at an outside air temperature of at least -5°C. Lower rates can lead to the appearance of microcracks and chips on the plastic elements of the window. In addition, negative temperatures lead to deterioration in the adhesion of polyurethane foam to the wall.

Fixing the window structure to the wall

The window is mounted in the opening using special bars, aligned in the vertical and horizontal directions. It is fixed to the wall using one of two methods - frame dowels and steel anchors.

If an anchor is used, one end of it is fixed to the window and the other to the wall. Such fasteners can be used to fix window blocks made of various materials.

The frame dowel is not such a universal solution, since it forces changes to the design. To fix the frame with its help, a hole is drilled in the window profile and the wall. A dowel is installed into the formed channel and screwed. All work is carried out by installers carefully, since tightening the dowel too much can lead to deformation of the window.

Upon completion of the installation of the window structure, the joints along its perimeter are foamed, and the outside material is protected with vapor barrier tape or a special liquid sealant. It allows you to prevent the influence of negative external factors on the foam.

Placing a window in a wall

It is necessary to correctly position the structure in external wall, since this will prevent the appearance of “cold bridges”.

When installing the structure in a single-layer wall, it is placed closer to the middle, which reduces heat loss. In double-layer walls window unit mounted flush with outer part masonry In this case, it is important that the insulation extends onto the profile at a distance of about 3 cm, covering the joint between the wall and the frame.

In the case of building a house with three-layer walls, the window structure is mounted in the insulating layer, in close proximity to the masonry of the load-bearing part of the wall. The resulting gap is filled with a special tape that prevents the negative effects of moisture and temperature changes on the structure.
