Sheet backing for laminate polystyrene foam 5 mm. Extruded polystyrene foam laminate backing

Special meaning among additional material during final installation of any flooring has a special backing. Its immediate tasks are to ensure sound absorption and warmth of the floor, hide its minor irregularities, etc. The market offers a huge range of substrates made from a variety of materials. But polystyrene models occupied a special niche.

Polystyrene is, in simple words, polystyrene foam or one of its types. It is produced in the form of slabs of sheets with small-fine pores, the product has a pleasant to the touch smooth surface or corrugated. The preparation of polystyrene is carried out by the process of foaming a certain substance, and when using water steam and volatile petroleum products, an almost weightless material with a cellular structure is formed. In everyday life it is called "sheet substrate"

Advantages of polystyrene backing

However, its airiness is ostentatious, since the strength, hydro- and thermal insulation are ideal. Despite the fact that the material contains volatile petroleum products, it is absolutely safe for human health.

In addition, such a substrate will stand guard over your floor covering and protect it from moisture, mildew or mold. It will withstand any load and will not lose its quality properties, just like the floor covering itself. The cellular structure and foil layer guarantee almost 100% low thermal conductivity of the material.

Its main advantages are:

• Very high degree protection against the formation of fungus and mold;

• the highest level of thermal insulation;

• good degree of noise protection;

• strength and reliability;

• protection from moisture.

However, such products also have some disadvantages. This is a high cost, low shock absorption properties and lack of microventilation.

Types of polystyrene foam substrates

There are numerous types and sizes available on the market today. of this material. It is sold in sections, which are connected using foil fabric. Products are available in several types. There is foamed polyethylene, and there is foamed polystyrene. However, these types should not be confused.

The first one belongs to the budget and cheapest segment, and accordingly, the quality does not differ. Yes, it is not afraid of moisture, mold or mildew, but it is not very good at sound insulation and durability, i.e. short-lived.

The second option has a durable structure and lasts quite a long time. It is also not afraid of moisture, fits perfectly, filling small irregularities, and has acceptable sound-absorbing and heat-insulating qualities.

In addition to these two types, there is also a foil composite. This substrate will be an excellent and optimal choice under the floor covering, especially under the “warm floor” system. The foil layer applied to foamed polystyrene reflects heat rays and significantly increases the efficiency of the “warm floor” system. At the same time, electricity and heating costs are significantly reduced.

Another type is extruded composite. His distinctive feature from the previous version is the production technology. It also stands out for such advantages as a high degree of sound insulation, ease of installation, and excellent resistance to moisture. The material is not afraid of chemical or biological influences and is ideally resistant to stress. Despite its synthetic nature, it is absolutely safe for human health.

The ideal thickness of this product is 3 mm, but you can also find substrates with a thickness of 2 mm and 5 mm. The substrate under the laminate is usually chosen with a thickness of 3 mm, and during installation parquet board use 5 mm.

Features of laying a substrate made of extruded polystyrene

Video "Laying polystyrene sheet substrate"

Laying this substrate is quite simple, but requires additional training. It is necessary to level the subfloor as much as possible. For increase soundproofing properties The floor must be covered with a special film that has thermoacoustic properties. And then you should lay the polystyrene backing. It is secured at the joints with masking tape.

In my work, when laying laminate flooring, I encounter various types materials. As insulation, a sheet substrate made of extruded polystyrene foam is regularly found, which will be discussed in this article.

Polystyrene was invented and patented in France in 1930. Extruded polystyrene foam first created in the USA in 1941, the product belongs to the petrochemical industry.

Polystyrene is formed by the polymerization of styrene. A viscous mass is driven through stirred reactors with benzene with a gradual increase in temperature in stages. Unreacted styrene is removed by vacuum. The output is a pure product, stably inert. That is, it is safe in a normal, non-aggressive environment.

The density of polystyrene is just over 1000 kg/m3. It is obtained in the form of cylindrical granules. Polystyrene is used for further processing: plastic disposable tableware with a sign (PS), sandwich panels, decorative baguette, backing and much more.

Expanded polystyrene - brief characteristics and composition

Expanded polystyrene is produced by the gasification method. A multiple increase in volume occurs due to the filling of granules carbon dioxide or natural. The flammability of polystyrene foam depends on this.

We get the material various densities from 40-150 kg/m3. The strength of the composition and vapor and air permeability depend on the specific gravity. Please note that this is not a finished substrate yet. Further processing will reduce the density of the material.

Extruded polystyrene foam - characteristics, composition

Actually, we got to the material from which the insulation is made. High pressure extrusion molding machine and high temperatures polystyrene is supplied through a narrow nozzle using a foaming agent. Gasification of the mass occurs. At the output we get, depending on the type of machine, finished product. In our case, this is a substrate for a laminate made of foamed polystyrene.

The density of extruded polystyrene foam is low - about 30-40 kg/m3. With a given specific gravity, the material has relative hardness, fragility, and high thermal insulation.

Polystyrene sheets for flooring

The substrate can be supplied in the form of rolls and more compactly - sheet slabs.

Extruded polystyrene foam (XPS) laminate underlay comes in two types:

• leafy
• roll

The sheet substrate, in turn, can be divided into types:

• individual plates
• harmonic

The main difference between them is only in the installation method. The name of the substrate - accordion - speaks for itself.

Laying must be done carefully, the connection of the plates is gentle. In case of a tear along the seam, you need to fasten the panels with tape. The requirement to fasten the material is due to the lightness of the litter and its mobility from gusts of air. The accordion substrate is faster than its usual sheet counterpart in terms of installation speed.

The material is supplied in cellophane packages. The width of the plates is 500-600 mm, and the length is 1000-1200 mm. The color of the lining directly depends on the dye: blue, pink, green, gray - for every taste.

The thickness of the substrate is varied: 2, 3, 5 mm.

Sheet backing for “Solid” laminate 2 mm

For example, we will take a sheet substrate for a laminate under a warm floor. About the best insulation for heated floors.

The “Solid” sheet substrate has a thickness of 2 mm and a density of about 40 kg/m3. The sheets are perforated to distribute incoming flows warm air from underfloor heating.

One well-known large retailer, Leroy-Merlin, has different data on the leveling ability of the lining. The description says one thing, the characteristics have other information. I should note that any insulation 2 mm thick has little ability to remove unevenness in the base. So think about what to believe - you can break your head from research.

The second contradiction from one trading company is the impossibility of using most brands of laminate for water-heated systems. The annotation of the “Solid” substrate states that it is suitable for warm water floors.

Manufacturers of laminate floors may need to undergo appropriate certification, worth the money and they are in no hurry to invest them. Or maybe they are afraid of condensate vapor escaping, which could ruin the floor covering. In any case, it is beneficial for the manufacturer to be less able to provide a warranty, which is what they do.

There is no guarantee for laying laminate flooring without using a 200 micron or 0.2 mm thick film..

The electric floor is hidden under cement screed. Therefore, its use will not harm either the laminate or the insulation, as long as the recommended temperature is observed, which for most laminate floors is 28 degrees Celsius.

However, polystyrene foam is a poor thermal conductor and I am not sure that perforation in positive side will have a significant impact on energy savings in your home. Moreover, to maintain the guarantee, there is a need to lay a vapor barrier film.

In this case, any substrate can be used under the laminate, without the use of ventilation holes.

Infrared heated floors, currently the most popular, are laid directly on the substrate. Then, on the contrary, the holes will theoretically serve as an outlet for thermal energy into the floor screed. And the thickness of this “Solid” lining, 2 mm, is too thin and the terminals will need to be recessed into the concrete base.

Price sheet substrate“Solid” with perforation for underfloor heating starts from 60 rubles/m2. Sold in packs of 8.4 m2.

Summary of “Solid” 2mm underlay with perforation for heated floors

You should pay attention to the substrate when using warm electric or water floors. However, low leveling ability and the need to use vapor barrier film makes warranty compliance difficult.

Sheet backing for “Solid” laminate 3 mm

It is more comfortable to work with a sheet substrate 3 mm thick. The main point is the greater leveling capability. If the base is uneven, under the weight of the laminate and furniture, the bumps are pressed down over time. This is how alignment occurs. Surface ribbing, which regularly occurs on the surface, contributes to shrinkage. back side at various types substrates 3 mm thick.

For example, let's take the Solid 3 mm substrate in the well-known Petrovich store. Packaging area 10.5 m2. The length is 10 meters, width 1050 mm. Folds out like an accordion.

What particularly interests me about extruded insulation is the density of the material. The specifications indicate that the density is 45 kg/m3. This is the average.

In one RuNet summary table it is indicated minimum value for extruded polystyrene 33 kg/m3, in our case 45 kg/m3, in well-known specialized markets they sell a substrate without specifying the manufacturer with a density of 55 kg/m3, which leads to some thoughts about a possible substitution of characteristics. Since hardly anyone will bother to measure the density of the substrate, and it is quite difficult to do this. The weight of the package is not indicated everywhere, and the presence of ribbing reduces the possibility of measurement to zero.

The accordion substrate does not have ribbing, therefore, using the indicated characteristics, in the Petrovich store, beloved by many builders, we can easily recalculate the density of the material.

Compound: extruded polystyrene foam (XPS).

Dimensions: thickness 3 mm, width 1.05 m, length 10 m.

Density: 45 kg/m³

Color: Orange.

Manufacturer: Russia.

Gross weight: 1.39 kg.

10*1.05=10.5 m2 – substrate area

10.5*0.003 (3mm thickness converted to meters) =0.0315 m3 – resulting volume

45*0.0315=1.4175 kg – the package must weigh net

1.39/0.0315=44.12 – actual density of the lining

As you can see, the difference is just over two percent. This difference is of no significance.

However, sellers of extruded polystyrene foam insulation argue in favor of this underlay over . Higher material density and longer service life are good reasons.

According to various sources, the foamed substrate has a density of 20-50 kg/m3. Which in maximum values ​​is comparable to extrusion. If we focus on the density of comparable materials, they are almost the same, with extruded polystyrene having a slight advantage.

Summary of the substrate “Solid” - accordion 3 mm

The underlayment is quite quick to install compared to conventional sheet insulation, but is inferior to foam insulation. roll material. I consider this point important for those who want to install laminate flooring themselves for the first time. It is always difficult to do something for the first time and spend too much time on any simple aspect. To put it bluntly, you can lose patience with flooring without even starting to do anything.

The price of “Solid” 3 mm is about 55 rubles per m2. Which is significantly more expensive than foam underlayment, but inferior to the more expensive ones: Tuplex, Profitex, cork... For the calculation, it is necessary to take into account that the sheet underlay from craftsmen is usually not included in the cost of laying floor coverings, so the total price rises to 75 rubles per square meter, which is comparable to expensive insulation.

Sheet backing for Aberhof laminate 5 mm

As an example, I present a sheet substrate for Aberhof 5 mm laminate. It is already difficult to write anything at all about the material about which almost everything has been said above.

The substrate is made of polystyrene foam by extrusion. The official website contains modest information about the characteristics. The package consists of 10 sheets, with an area of ​​5.25 m2, dimensions 1050 mm by 500 mm and a thickness of 5 mm.

The 5 mm substrate has higher sound insulation and thermal insulation properties compared to 3 mm lining, on average by 20%.

The density of the slab is 35 kg/m3.

The 5mm pad has high leveling performance up to 3.5mm.

For extruded polystyrene foam specific gravity Aberhof lining is quite low. It is depressing that there is no information on the website about fire certification, compliance with sanitary and hygienic requirements, or a PCT certificate of conformity.

Summary of Aberhof underlay 5 mm

Please note that laminate manufacturers do not extend the warranty to floor coverings with a used underlay more than 3 mm thick.

I can see the use of sheet Aberhof 5 mm on a limited budget to level the floor level between rooms. Keep in mind that the lining will shrink over time.

The material being tested is indispensable when laying laminate or parquet boards in rooms with an uneven base. When there is no time or opportunity to level.

Rolled backing made of extruded polystyrene “Solid”

This product is supplied in rolls with an area of ​​16.5 m2. The length of the canvas is 15 meters, width 1.1 meters, thickness 2 mm.

A density of 50 kg/m3 is considered high.

The flammability class of the material is G4 – highly flammable.

The numbers are not documented on the website. No certificates found.

Summary of roll substrate “Solid” 2 mm

Rolled backing is extremely difficult to work with. It breaks easily and rolls back into a roll. Have to press against concrete base with improvised means.

It is realistic to use 15 square meters. Closer to the base, the lining, when viewed in profile, takes on a spherical shape. To be able to lay it, you need to cut it into pieces. This all looks extremely unprofessional.

The price of a roll of extruded polystyrene 2 mm is about 35-40 rubles/m2.

I express my deep conviction. It is better not to buy this insulation.

Pros and cons of extruded polystyrene foam sheets

For comparison, we consider sheet insulation, since it is more widely used than roll insulation.

Advantages of sheet extruded substrate

• Higher density and likely lifespan of the material compared to foam litter.
• Relatively low price from 35 rubles/m2.
• The insulation is not susceptible to rotting and mold.
• Compact storage.

Cons of Sheet Extruded Backing

• High flammability of the material.
• Longer laying time compared to rolled Plenex.
• The curved shape of the sheets is regularly found.
• Fragility of the material.
• The lining is “not indifferent” to a poorly prepared base. Small stones tear the “body” of the extrusion.
• To comply with the warranty, laminate manufacturers require laying vapor barrier foam.

When installing flooring important role It is not only the high-quality finishing material that plays a role, but also the entire pie, starting from the base. An important role is played by the substrate, which compensates for the load when walking, reduces the “ringing” of the coating and protects it from moisture. Expanded polystyrene under laminate is used quite often and this is due to its unique performance properties.

Expanded polystyrene has several varieties depending on the method of its manufacture.

Table 1. Types of polystyrene foam

Name	Description
	Expanded polystyrene labeled PSB (EPS) is used for wall insulation. Its variety marked PSB - C is less fire hazardous.
	Material marked EPS (XPS) has high strength for compression.
	Material marked PS-1, PS-4 has a high density.

Characteristics of extruded polystyrene foam

More often, substrates made from this particular material are used under the laminate. The peculiarity of its structure lies in evenly spaced closed cells, which ensures the moisture resistance of the material. The substrate is manufactured using an extrusion molding machine, where polystyrene along with a foaming agent is fed through a narrow nozzle under high pressure and high temperatures. The result is a material with low density (30-40 kg/m³).

The material does not rot and does not absorb moisture. When wet, water does not penetrate further than the open side honeycombs at the cut. It is distinguished from its analogues by its greater strength and thermal insulation properties. Substrates made from this material are produced in rolls and in the form of sheets, measuring 1000 x 500 x 3 mm.

Table 2. Characteristics of polystyrene foam

Advantages and disadvantages of the material

The advantages of polystyrene foam substrates include the following:

1. The high strength and durability of the material make it possible to create high-quality flooring that will maintain its integrity and aesthetic appeal for many years.
2. The porous structure guarantees high thermal insulation properties of such a substrate.
3. The relief surface provides natural circulation air between the substrate and the base, while moisture and condensation will not penetrate further than the substrate.
4. The thickness of the substrate allows you to hide minor unevenness of the base.
5. The material is not afraid low temperatures, therefore can be used in unheated rooms.
6. Laminate is a rather loud coating, and the substrate with a porous structure in the form of sealed cells filled with air perfectly absorbs noise.
7. The material is lightweight and convenient in size, which makes it easy to transport and install.
8. The cellular structure and homogeneous composition make this material resistant to ammonia, alcohol, propane, salts and alkalis.
9. Expanded polystyrene does not change its physical properties even under heavy loads.
10. The material is not subject to rotting, it is environmentally friendly and safe for humans and the environment.

One of the disadvantages is the small thickness of the substrate, due to which it has low leveling ability. Therefore, the base must be leveled with special compounds or slabs. Otherwise, if the difference exceeds 1 cm, after some time a squeak will appear when walking on the laminate.

Another disadvantage is that the material is not sold in parts. If the room is small, you will still have to buy the entire package.

Types of substrates

Expanded polystyrene is used to make several types of materials that can be used as a substrate for laminate flooring. They differ in thickness and performance characteristics. Expanded polystyrene boards are often equipped with milled end grooves, ensuring a tight fit of the elements to each other.

Note! Due to the low coefficient of water absorption, a substrate made of extruded polystyrene foam can be safely used in rooms on the first floor, without focusing on the depth of groundwater.

To ensure thermal insulation of a laminate flooring, it is enough to use a three-millimeter underlay. It is produced in the form of sheets of 20 pieces per package. A convenient backing is folded into an accordion. Between such sheets a minimal amount joints due to the fact that the material, when unfolded, is laid along the entire length of the room.

Polystyrene sheets for flooring

As noted earlier, polystyrene foam backing can be rolled or in the form of sheets. The second variety is available in the form of separate plates or an accordion. They differ only in the installation method.

When laying sheets with an accordion, be careful not to damage the joint of the sheets. If this happens, the gap is sealed with ordinary tape. Also, using tape, the individual sheets are fastened together so that they do not fly apart. The advantage of an accordion is that its installation is much faster.

With a sheet length of 1000 - 1200 mm and a width of 500 - 600 mm, the thickness of the product can vary from 2 to 5 mm. There are several types of sheet substrates.

"Solid" 2 mm thick

This variety can be used in a heated floor system. The density of the “Solid” sheet substrate with a thickness of 2 mm is 40 kg/m³. To prevent the substrate from being an obstacle to the heat flow coming from the coolant, it is perforated.

Note! Since the leveling ability of a material with such a thickness is minimal, and the laminate must be laid on a flat base, it is necessary to carefully consider the preparatory stage.

When installing the coolant (pipes with water or electric cable) into the screed, during the operation of the heated floor, make sure that its temperature does not exceed 28 degrees. When creating a vapor barrier layer, the substrate may not have perforations.

If you are installing an infrared heated floor, when the heating elements are laid directly on the substrate, you should choose a material without perforation to avoid heat loss.

The cost of this type of polystyrene foam substrate starts from 60 rubles/m². The package contains material to cover a surface area of ​​8.4 m².

It is recommended to purchase “Solid” polystyrene foam substrate with a thickness of 2 mm for electric or water heated floors.

"Solid" 3 mm thick

The 3 mm thick substrate is more comfortable to use and has a better leveling effect. Ribbed surface on back side The sheet promotes shrinkage of the material under load.

The accordion-shaped type of polystyrene foam backing is 10 meters long and designed for an area of ​​10.5 m². Its average density is 45 kg/m³. There is no ribbing on the back side. Compared to foam substrates, which are also often used when laying laminate flooring, this option has greater density and durability.

As previously noted, accordion-shaped material is laid faster than sheet counterparts. The cost of the material starts from 55 rubles per m² and exceeds the price of a foam roll analogue.

"Aberhof" 5 mm

Aberhof 5mm sheet substrate is sold in 10 sheets per package, designed for a surface area of ​​5.25 m². The size of one sheet is 1050 x 500 x 5 mm. This variety is characterized by higher sound and heat insulation properties (higher than the three-millimeter one by about 2%). The sheet density is 35 kg/m³. The advantage of the material is its high leveling ability (3.5 mm).

When using such a substrate on an uneven floor, it must be taken into account that it shrinks over time. However, this type of underlay is best suited for laying laminate and parquet flooring where the substrate is uneven.

Advantages and disadvantages

Extruded sheet polystyrene foam substrate has the following positive properties:

1. High density and long service life when compared with a foamed counterpart.
2. Relatively low cost, which starts from 20 rubles per 1 m².
3. The material does not rot or mold.
4. Available in a convenient format and packaging, which facilitates the process of transportation and installation.

Disadvantages include:

1. Flammability of the material.
2. The package may contain defective sheets of curved shape.
3. Due to their fragility, sheets must be laid carefully.
4. You need a perfectly flat and clean base without small pebbles that could disrupt the integrity of the sheet.
5. The need to use a vapor barrier film.

Review of the best of the most popular

To recommend you the best substrates, we took into account the opinions of representatives of manufacturers of the most popular laminate brands, analyzed reviews of craftsmen and users on specialized Internet resources and construction forums, and technical characteristics of materials.

Selection criteria

We made the selection based on the parameters below, which we suggest you use as a guide when making your choice.

Noise absorption

This means the absorption of “impact” (reflected and transmitted) noise. Reflected noise is what you hear when you walk on the floor; transmitted noise is what your neighbors below hear. Let’s be clear right away: NO underlayment will save YOU from the noise of your neighbors underneath you, it’s YOU who saves them from the rumble of your heels.

Relation to moisture

Substrates from different groups react differently to moisture. Please note that an indispensable condition for the warranty on laminate from the manufacturers is the presence of a waterproofing film with a thickness of 200 microns.

Thermal insulation

This indicator is important if the floors are located above basements, unheated garages, or passageways.

Density, thickness

For laminate flooring, the ideal is the most solid base possible. In this case, wear on the locks will be minimal. The softer and thicker the substrate, the faster the coating will deteriorate. If the thickness is greater than the optimal(!) 3 mm, then there is a high probability of cracks appearing due to wear of the locks.

Reaction to unevenness of the main floor

The denser the material (and cork has the highest density), the worse its leveling abilities and the more carefully the base should be leveled. You can’t even out a large radius curvature with anything!

Lifetime

Under an expensive laminate with a lifespan of 15 years, it is not economically feasible to lay a cheap polyethylene backing that will wear out in a couple of years.

Suitable for use with heated floors

This characteristic is relevant for those who plan to lay laminate flooring on heated floors.

Ease of installation

Some types of rolled substrates (cork, in particular) tend to curl up when laid. In this case, it is better to take sheet material.

The best manufacturers (brands) of substrates

Famous manufacturers laminates, it is strongly recommended to use branded substrates for your products. Otherwise, they reserve the right to refuse to consider a claim if one arises. However, they all favor cork substrates from Portugal and VTM brand extruded polystyrene. Excellent reviews of Parkolag and Isoplin from both installers and buyers. NPE substrates from Quick Step have proven themselves well in operation. But the domestic analogue will provide you with “bubbles” and “waves” after installation. We also do not recommend extruded polystyrene from Russian and Chinese brands: their product descriptions overstate their characteristics.

Average price in Russia: 90 rub./m2, thickness 2 mm (145 rub./m2 - thickness 3 mm)

Advantages: One of the best substrates made in Portugal, Spain. Very high density means that both itself and the laminate locks are resistant to deformation under load. Due to its high damping properties, the floor will not “play” over time. Due to its very low thermal conductivity it is good insulation floors above unheated rooms. Since it dampens noise well, it will be an excellent solution for children's, game rooms. Can be used with laminate high class, without requiring replacement, 25 years. Unlike its Chinese counterpart, it does not crumble, is easy to install and use, and does not harm the laminate.

Flaws: High price. Noisy on a poorly leveled base. Best used on wooden floor, plywood, chipboard. Absorbs moisture, therefore requires waterproofing of concrete and is not recommended for wet rooms and kitchens.

Typical reviews
“We need to remove the base under the cork more carefully! I encountered this..."
“...hard to lay down. When the roll ends, the cork tends to move back strongly, and there is a fear that it, crumpled, will fall under the laminate.”

Parkolag
Rating 9 out of 10

Photo: strmnt.ru

Average price in Russia: 95 rub./m2, thickness 3 mm

Advantages: High noise absorption, wear resistance, and very high moisture insulation make this ventilated substrate one of the best. Cork powder, which retains its elasticity, promotes long service laminate, and bitumen prevents the penetration of moisture from concrete screed. The presence of air exchange prevents the formation of condensation, fungus, and mold. Saves linear dimensions under very significant pressure and with changes in temperature and humidity conditions. A reliable substrate that will be an excellent solution for expensive brands of laminate and will serve for many years without causing problems.

Flaws: Cannot be used under heated floors.

Reviews:
“Compared to technical cork, the mixed version is more versatile and more wear-resistant. Benefits in terms of a barrier to excess moisture.”
“As a substrate, I always liked Pargolag, about which I heard a lot of stories, like it stinks of bitumen in a way that is not childish, etc. All this is nonsense.”
“I bought a parkolag for laminate flooring. Great! And there’s no smell, and thiiiiiiho...”

Isoplat (Isoplaat startfloor barlinek)
Rating 9 out of 10

Photo: bug.ua

Average price in Russia: 55 RUR/m2 (thickness 5 mm)

Advantages: An ideal substrate for heated floors due to its absolute safety when heating. Thanks to its porous structure, it has good noise- and sound-absorbing, acoustic and heat-insulating properties, and heat resistance. The special structure of the bottom layer allows air to circulate freely, providing ventilation properties. Moreover, thanks to antiseptic impregnation protected from fungus and mold. In terms of elasticity, thermal conductivity, resistance to compression, sound absorption, durability and naturalness, it is similar to cork. As for thermal insulation, due to the thickness of Izoplat it is 3 times higher and comparable to soft insulation.
Flaws: Slabs of smaller thickness are not available.
Reviews:
“I have 5 mm isoplaat under 33 laminate. Elastic, warm to the touch, dampens noise well. With two small children, the neighbors downstairs simply don’t hear us (their opinion).”

Rating 10 out of 10

Photo: skill-spb.ru

Average price in Russia: 55 rub./m2 (thickness 3 mm)

Advantages: A stable base for laminate floors, making it comfortable even diagonal laying laminate Thanks to its closed, moisture-proof pores, it is ideal waterproofing. Optimally selected density is expressed in a sufficiently high resistance to external pressure and at the same time the absence of strong rigidity. The latter quality compensates for floor unevenness up to 3 mm and enhances sound insulation: the impact noise absorption rate is close to cork. Specifications similar to Isoplat plates. Mechanical pressure does not have a destructive effect on the structure, so VTM and IsoPolin substrates do not lose their high heat and sound insulating properties over time. Service life more than 10 years.

Flaws: Not suitable for rooms with high intense traffic and load (dance halls, fitness clubs, etc.). Not suitable for heated floors.

Reviews:
“In terms of laying properties and resistance to subsidence, XPS substrates and Isoplats are almost identical.”
“As a builder, I will say: it’s pleasant and easy to work with; many customers require just such a substrate.”
“In the Olympic Village ... there is a huge demand for this substrate among understanding people.”

The best polyethylene substrates

Tuplex
Rating 9 out of 10

Photo: ekopol.kiev.ua

Average price in Russia: 99 rub./m2 (thickness 3 mm)

Advantages: Tuplex underlay adapts to the shape of the base, smoothing out small defects. Perfectly absorbs impact noise, muffling the sound of heels. This quality allows us to recommend Tuplex for both residential premises and offices. Due to low compression (14 times less compared to foamed polyethylene), it retains its shape well and prevents the laminate from sagging. The unique structure of the material allows moisture to be removed naturally, but this advantage is reduced to zero in the presence of a waterproofing film. Suitable for heated floors.

Flaws: The heating efficiency of heated floors is lower compared to traditional thermally conductive substrates due to the dissipation of part of the air.

Reviews:
“The best...thing I've worked with is Tuplex. Very easy to install."
“I heard complaints about him. The main idea: polystyrene foam balls deform over time... This may not be true, but it’s worth thinking about.”
“...tried compression, but it doesn’t recover. Although the annotation says something else.”

Izolon PPE
Rating 8 out of 10

Average price in Russia: 35 RUR/m2 (2 mm)

Advantages: Good heat and noise absorption parameters of “cross-linked” polyethylene with closed pores, its environmental friendliness, elasticity and elasticity, increased moisture resistance and hydrophobicity, inertness to “chemistry”, bacteria and relative cheapness make the Izolon PPE substrate (not to be confused with Izolon NPE!) preferable for use in residential and public spaces. These qualities can be maintained by Izolon PPE for a long time under any operating conditions. Does not deform under load, does not burn and does not emit toxic substances. Over time, it does not collapse, does not lose stability and strength, unlike gas-filled polyethylenes Izolon NPE, Penofol, Poliizol, etc. Service life in normal conditions more than 25 years. Optimal solution for heated floors.

Flaws: Despite the good thermal insulation properties, you should not count on thermal insulation of the floor with a material thickness of 2-4 mm.

Reviews:
“If you take Izolon, then PPE is white with very dense small bubbles, but not our NPE!”
“Compared to cork, Isolon has much worse compression and recovery.”

Foil Izolon PPE
Rating 6 out of 10

Average price in Russia: 56 RUR/m2

Advantages: In addition to the advantages of Izolon PPE, the foil layer, which is a reflective thermal insulation, enhances heat and vapor barrier properties and reduces heat loss by 97%. Important: the higher the temperature difference between the subfloor and the room, the higher the effectiveness of foil thermal insulation. For the first floor with a concrete floor, foil-coated Izolon PPE is useful; for an apartment on the fourth floor there will be no gain in temperature. But as insulation, it combines perfectly with infrared heated floors.

Reviews:
“For the foil to give a noticeable effect in heat reflection, the temperature must be around 60° C. Therefore, foil on foam...successful marketing ploy…».
“...living in a plastic bag requires constant ventilation.”

Which underlay is best to buy?

Even professionals often have a diametrically opposed attitude towards the same group of materials, and most often it is poorly reasoned. Our rating of the best substrates does not give a clear answer to this question—the choice is yours. Study the characteristics of the material and choose the one that best suits your tasks, the degree of evenness of the base and your financial capabilities. However, keep in mind that thicker does not mean better; the thickness of the substrate should not exceed 3-4 mm, unless greater is allowed by the laminate manufacturer.
