What is the best underlay for laminate flooring? Substrate under the laminate coniferous. Substrate under the laminate - how to choose? Substrate under the laminate - which is better Vapor barrier under the laminate
Laminate has become one of the most popular and cheapest floor coverings. It is strong, durable, pleases with a wide choice - from budget to elite models of any color. As a rule, people spend a lot of time choosing a laminate, but they forget about the substrate. In this article, we will figure out which substrate is better, because the durability of the coating depends on its quality.
Underlayment for laminate flooring is required by floating floor technology. This is due to several factors, which we will talk about.
- Soundproofing. If the bedding under the laminate is not used, then each step will be given a booming thud. The presence of a soft even layer will hide small noises, frictions (see article about).
Sometimes in the 33rd and 32nd class of laminate there is a built-in substrate: an insulation layer is already glued on the reverse side. It is more convenient to lay such material than usual, but due to the more difficult production technology, the cost increases significantly.
- Surface leveling. Another function of the substrate is to level small irregularities. This is very important when, because the durability of the locks depends on the evenness of the base. According to technology, the allowable floor differences should be no more than 2 mm per 1 m. However, too much thickness of the substrate under the laminate will rather prevent bumps from hiding, because then it will sag at the joints when walking. So that the seams do not spread in six months, the floor surface is carefully prepared before laying the coating (see article on.
- Moisture isolation. The laminate is made of pressed paper, so even moisture-resistant models do not need to be exposed to high humidity, otherwise the panels will swell. Laying the substrate under the laminate will provide additional protection against moisture from the concrete floor. For the same reason, before laying the coating, it is better to wait at least a month after the installation of the concrete screed.
As a test of the readiness of the screed, you can put polyethylene on the floor overnight. In the morning, there should be no perspiration on the concrete.
- Thermal conductivity. A conventional underlay for a laminate installed under a warm floor reduces the efficiency of its work, since both the laminate itself and the substrate material have good thermal insulation properties. There are special substrates for underfloor heating, which we wrote about in. We also recommend that you familiarize yourself with, which describes the installation process on a wooden and concrete base with further finishing with laminate.
Substrate selection
It's easy to find plenty of options at any hardware store, but how do you choose the right underlay for laminate flooring? After all, they differ in material, thickness, sound insulation.
First of all, you need to find out the condition of the floor. If the base is even, the thinnest substrate will be enough - 2 mm. When small irregularities are encountered, it is worth choosing an insulation thickness of 3 mm. The thickness of the laminate with the underlay will be approximately 10-11 mm (assuming an average laminate floor thickness of 8 mm).
When choosing a substrate and the laminate itself, it is not necessary to give preference to the same manufacturer. It practically does not matter, because the parameters are general, so any company will do.
A brief video review of popular species:
Polyethylene foam
The most common polyethylene foam backing. Its popularity is primarily due to its low price. In addition, it has good moisture resistance, thermal insulation and is not affected by rodents and microorganisms. This material is very easy to use and minimizes waste. Often it is supplemented with a foil layer with aluminum for reflection infrared heat.
However, despite a large number of advantages, the cheapest material also has many disadvantages. First of all, it is a non-environmentally friendly synthetic material, which sags over time and does not hold its shape well. There are cases that after laying the laminate on a polyethylene foam substrate, static electricity is generated (especially in dry rooms), and the owners are periodically shocked. Therefore, think 10 times before saving 500 rubles, is your comfort worth this money? Material is cheaper domestic manufacturers: price per roll 25 sq. m. about 320-400 rubles. Foamed polyethylene from Quick step will cost 60-90 rubles. for 1 sq. m.
Cork substrates
Cork underlayment under laminate flooring is great as a base for a floating floor. Although it is a natural material, cork is not subject to mold and decay, and is an excellent heat insulator. Throughout the entire service life, such a substrate will retain its dimensions and characteristics. This type is available in the form of rolls or sheets. In some cases on reverse side there is a self-adhesive layer (see article about). 
Due to the high cost, it is impractical to use the cork option for cheap coatings, but it is well suited as a durable base. The disadvantage of cork is water permeability, so condensation may appear under the coating.
Bitumen-cork substrates
This material is made on the basis of kraft paper with the addition of bitumen, and then covered with fine cork chips on top. The dressing is made from small pieces of cork 2-3 mm. Thanks to bitumen, this type is devoid of the disadvantages of conventional cork: it does not allow moisture to pass through and retains sounds well; the material breathes, which prevents the formation of condensate. Like the previous option, bitumen-cork substrates are only suitable for expensive types of laminate, due to the high price.
Styrofoam
Often, extruded polystyrene foam is used as an insulating layer. It is optimally suited for high-loaded premises and evens out irregularities well. This is one of the most effective heaters due to the high air content in its composition. Due to its rigidity, it retains its shape well and effectively absorbs sounds, does not let moisture through. When using expanded polystyrene on the floor, a comfortable feeling when walking is provided. The most popular in this form are products from Izoshum, Arbiton. 
Combined options
There are also combinations of polyethylene and expanded polystyrene. The most famous substrate is Tuplex (Tuplex), it consists of two layers of polyethylene, between which there are polystyrene foam balls. 
This combined option Sold in rolls and has a thickness of 3 mm. Due to its structure, it can ventilate the room. The upper layer does not allow moisture to penetrate inside, and a thin lower layer passes it inside to the granules, and from there it comes out through technological gaps.
Coniferous tiles
A novelty of recent years is a coniferous substrate for laminate flooring. It is difficult to find it in stores due to its high cost, but coniferous boards from Isoplat are sometimes sold. The material is completely environmentally friendly and allows air to pass through, so there will be no greenhouse effect under the floor. However, in terms of elasticity, the needles are inferior cork. It is also worth considering that the minimum thickness of coniferous tiles is 4-5 mm, which is contrary to the requirements of many laminate manufacturers. The tiles are laid diagonally.
Substrate laying
Now let's talk about the technology, how to lay the substrate under the laminate:
- If there is a fresh concrete screed on the floor, a layer of thin 0.2 micron polyethylene should be laid before laying. In older houses, this is not necessary.
- Thoroughly clean the floor of debris, vacuum all the dirt. The base must be dry.
- For cutting, use ordinary scissors or a construction knife. They overlap the walls, then the plinth will close it.
- In no case do not lay several layers of the substrate to compensate for irregularities, a layer of 2-3 mm will be enough. If you need more, they are produced with plywood, screed or in another way.
- If the material has a corrugation, it is laid down with this side, so there will be less irregularities. The foil material is laid with the reflective side up.
- Laying is carried out end-to-end, without overlapping sheets on each other. In order not to displace the substrate during work, it is recommended to stick it on a double-sided adhesive tape to the floor.
Summing up
Subject to the technology and the purchase of a high-quality substrate and laminate, they will last more than 10 years at home. Of course, the final choice will depend on material possibilities, but it is better to try to purchase high-quality natural materials so as not to pay twice.
Overview of the best of the most popular
In order to recommend the best substrates to you, we took into account the opinion of representatives of manufacturers of the most popular laminate brands, analyzed the reviews of masters and users on specialized Internet resources and construction forums, specifications materials.
Selection criteria
The selection was made by us on the basis of the parameters below, which we offer you to be guided by when choosing.
Noise absorption
By this is meant the absorption of "shock" (reflected and transmitted) noise. The reflected noise you hear when you walk on the floor, the passing one is the one that is heard by your neighbors below. Let's make it clear right away: NO backing will save YOU from the noise of your neighbors under you, it is YOU who save them from the roar of your heels.
Relation to moisture
Substrates from different groups react differently to moisture. Please note that an indispensable condition for the guarantee for laminate from 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, walkways.
Density, thickness
For laminate, the ideal is the most solid base. In this case, the wear of the locks will be minimal. The softer and thicker the substrate, the faster the coating will become unusable. If the thickness is more than the optimal (!) 3 mm, then there is a high probability of the appearance of cracks due to the wear of the locks.
Reaction to uneven ground floor
The denser the material (and cork has the highest density), the worse its leveling ability and the more carefully the base should be leveled. The curvature of a large radius you will not align with anything!
Lifetime
Under an expensive laminate with a lifespan of 15 years or more, it is not economically feasible to lay a cheap polyethylene substrate, which will wear out in a couple of years.
Suitable for use with underfloor heating
This characteristic is relevant for those who plan to lay laminate on underfloor heating.
Ease of installation
Some types of roll substrates (from cork, in particular) “strive” to curl up when laying. In this case it is better to take sheet material.
The best manufacturers (brands) of substrates
Notable Manufacturers laminate for their products, it is strongly recommended to use branded substrates. Otherwise, they reserve the right to refuse to consider the claim, if any. However, all of them favor cork substrates from Portugal and VTM brand extruded polystyrene. Excellent reviews about Parkolag and Isoplin from both installers and buyers. Well proved in operation of a substrate from NPE from Quick step. But the domestic analogue will provide you with "bubbles" and "waves" after laying. We also do not recommend extruded polystyrene of Russian and Chinese brands: in the product description, their characteristics are overestimated.

The best natural substrates
Let us immediately clarify that the natural origin of the substrate in this case does not give any advantages in terms of ecology, since on top of it there will be a laminate, which, as you know, is artificial material.
Cork underlayment Premium Cork (Cork)
Rating 9 out of 10
Photo: vopros-remont.ru
Average price in Russia: 90 rub./m2, thickness 2 mm (145 rub./m2 - 3 mm thick)
Advantages: One of the best substrates Made in Portugal, Spain. Very high density means that both the laminate itself and the locks of the laminate are resistant to deformation under loads. Due to the high damping properties, the floor will not “play” over time. Due to its very low thermal conductivity, good insulation floors above unheated rooms. Since it dampens noise well, it will become great solution for children's, game rooms. Can be used with laminate high class, not requiring replacement, 25 years. Unlike the Chinese counterpart, it does not crumble, is good in installation and operation, and does not harm the laminate.
Flaws: High price. Noisy on poorly leveled ground. It is best to apply on wooden floor, plywood, chipboard. Absorbs moisture, therefore requires concrete waterproofing and is not recommended for wet rooms and kitchens.
Typical Reviews
“It is necessary to carefully remove the base under the cork! I encountered this…”
“... it's hard to lay. When the roll ends, the cork tends to pull back strongly, and there are fears that it, crumpled, will fall under the laminate.
Parkolag (Parkolag)
Rating 9 out of 10
Photo: strmnt.ru
Advantages: High noise absorption, wear resistance, very high moisture insulation make this ventilated underlay one of the best. Cork powder, which retains its elasticity, contributes to the long service life of the laminate, and bitumen prevents the penetration of moisture from the concrete screed. The presence of air exchange prevents the formation of condensate, fungus, mold. Maintains linear dimensions under very significant pressure and changes in temperature and humidity conditions. A reliable underlay that will be an excellent solution for expensive laminate brands and will serve without causing problems for many years.
Flaws: Cannot be used under underfloor heating.
Reviews:
“Compared to technical cork, as a mixed version, it is more versatile, moreover, more wear-resistant. Wins in terms of a barrier to excess moisture.
“As a substrate, I always liked Pargolag, about which I heard a lot of tales, such as bitumen stinks not like a child, etc. All this is nonsense.”
“I bought a parking lot for laminate flooring. Fine! And there is no smell, and teeeee…”
Isoplat (Isoplaat startfloor barlinek)
Rating 9 out of 10
Photo: bug.ua
Advantages: An ideal substrate for underfloor heating due to its absolute safety when heated. Due to the 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 free air circulation, providing ventilation properties. In addition, 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 Isoplat, it is 3 times higher and comparable to soft insulation.
Flaws: Plates of smaller thickness are not produced.
Reviews:
“I have a 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).”
Best Extruded Styrofoam Underlays
VTM, IsoPolin (Isopolin)
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 flooring, making it comfortable even diagonal laying laminate. Due to the closed moisture-proof pores, it is an 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 irregularities up to 3 mm and enhances sound insulation: the impact sound absorption index approaches cork. Technical characteristics are 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 areas with high traffic and load (ballrooms, fitness clubs, etc.). Not suitable for underfloor heating.
Reviews:
“In terms of laying properties and resistance to sagging, XPS underlay and Isoplat are almost identical.”
“As a builder, I can say that it is pleasant and easy to work with him, 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 (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 it out small defects. Superbly absorbs impact noise, drowning out the sound of heels. This quality allows us to recommend Tuplex for both residential and office use. Thanks to its low compression (14 times less than polyethylene foam), 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 underfloor heating.
Flaws: The heating efficiency from underfloor heating is lower compared to traditional heat-conducting substrates due to the dispersion of part of the air.
Reviews:
“The best… I've worked with is Tuplex. Very easy to fit."
“I heard complaints about it. Key takeaway: Styrofoam balls deform over time… Maybe that’s not the case, but it’s worth thinking about.”
“... I tried for compression - it is not restored. Although the annotation says otherwise.
Isolon PPE
Rating 8 out of 10
Photo: www.web4market.biz
Advantages: Good heat and noise absorbing parameters of “cross-linked” polyethylene with closed pores, its environmental friendliness, resilience 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!) preferred for use in residential and public buildings. These qualities can be maintained by Izolon PPE for a long time under any operating conditions. Does not deform under load, does not burn or emit toxic substances. Over time, it does not collapse, does not lose stability and strength, unlike gas-filled polyethylenes Isolon NPE, Penofol, Poliizol, etc. The service life under normal conditions is more than 25 years. The best solution for underfloor heating.
Flaws: Despite the good thermal insulation performance, you should not count on the thermal insulation of the floor with a material thickness of 2-4 mm.
Reviews:
“If you take Izolon, then the PPE is white with very dense small bubbles, but not our NPE!”
“Compared to cork, Izolon has much worse compression and recovery.”
Foil Izolon PPE
Rating 6 out of 10
Photo: www.dom-laminata.ru
Advantages: In addition to the advantages of Izolon PPE, the foil layer, which is a reflective thermal insulation, enhances the heat, vapor barrier properties, reduces heat loss by 97%. Important: the effectiveness of foil thermal insulation is higher, the higher the temperature difference between the subfloor and the room. For the first floor with a concrete floor, foil Izolon PPE is useful, for an apartment on the fourth floor there will be no gain in temperature. But as a heater, it goes well with an infrared warm floor.
Reviews:
“In order for the foil to give a tangible effect in heat reflection, the temperature should be. around 60°C. Therefore, the foil on the foam ... a good marketing ploy ... ".
"...living in a plastic bag requires constant ventilation."
What is the best underlay to buy?
To the same group of materials, even professionals often have a diametrically opposed attitude, and most often poorly reasoned. Our rating of the best substrates does not give an unequivocal answer to this question - the choice is yours. Study the characteristics of the material and choose the one that best suits the tasks, the degree of evenness of the base and your financial capabilities. At the same time, keep in mind that thicker does not mean better, the thickness of the substrate should not exceed 3-4 mm, unless a larger one is allowed by the laminate manufacturer.
Purpose.
Rolled technical cork GREEN LIFE is used as an underlay for floating floor coverings.
It is an environmentally friendly and natural material with thermal insulation properties, designed to make your home more comfortable. The cork underlay is designed to reduce noise, improve thermal insulation, smooth out minor defects and irregularities in the base. Recommended for mechanical deformation protection and suitable for commercial and residential use on most floor coverings.
Storage.
The cork underlay must be kept in a dry, well-ventilated area protected from direct sunlight and moisture for at least 48 hours prior to laying. During storage and laying, the temperature and relative humidity must be maintained at the level of constant use of the building (temperature 18°C - 26°C, relative humidity 30%-75%).
Screed preparation.
The substrate must be firm, dry, smooth, even, free from dust and any other contaminants. Relative humidity of cement-sand screed< 2,5% (СМ).
Polyethylene vapor barrier film.
Be sure to lay a polyethylene vapor barrier film under the cork substrate, which should go 50 mm onto the wall along the perimeter of the floor. A continuous vapor barrier film is recommended, if this is not possible, then the film is overlapped, with an overlap of at least 200 mm. Mounting to the base is possible, for example, with double-sided tape. It is forbidden to attach by any mechanical means - staples, screws, etc., which can damage the film or cork backing.
Use with floor heating systems.
GREEN LIFE cork underlay is suitable for use with floor heating systems. Keep in mind that cork has a high thermal insulation performance, choose an appropriate floor covering that is compatible with heating systems.
Installation instructions.
Starting from one of the walls, roll the GREEN LIFE cork backing along the longest wall in the room. Cut off the length, leaving about 30 mm of overlap on the wall. Continue loosely laying the next row of rolled cork backing side by side with the previous one so that the side edges touch. Seal the joints with adhesive tape so that they do not open when the flooring is laid. When completed, the GREEN LIFE cork underlay should completely cover the floor area without gaps, with tightly bonded and film-bonded joints.
Attention!!! Never attach the GREEN LIFE cork underlay to the substrate mechanically. Always follow the flooring manufacturer's instructions.
Due to its practicality, laminated flooring became very popular. But in order for such a coating to fully reveal all its positive qualities, a substrate for a laminate is needed. The lining smooths out the unevenness of the floor, is both vapor and sound insulation.
Of course, there are many materials for the manufacture of substrates, all of them have various characteristics and they are all good in their own way. Among other things, the lining performs the function of a kind of shock absorber - so that the floor covering does not bend under loads and does not play when walking. Let's look at what types of substrates for laminate flooring are.
Foamed polyethylene
The most inexpensive roll substrate. In addition to the attractive price, the advantages of this material are:
- Excellent moisture resistance.
- It is not subject to formation of a mold and fungi.
- Good thermal insulation.
- Undemanding to subfloor(permissible difference in height up to 4 mm).
But like most inexpensive materials, polyethylene foam is not without disadvantages:
- Weak mechanical strength - easily torn.
- Relatively quickly sags under the influence of loads.
Basically, this type of lining is used for inexpensive repairs and commissioning of budget facilities.
Foil polyethylene foam
The next type of substrate is also made from foamed polyethylene, but has a base. It is the foil base that makes it possible to somewhat improve the technical characteristics of the substrate. There are two ways to lay this material:
- If it is necessary to protect the laminate from the effects of a damp or cold floor (for example, on the ground floor above a damp basement), the substrate is laid with the foil down.
- To reduce heat loss or when installing underfloor heating, lay foil up.
A version with double-sided foil is also available, but this material is more expensive.
Advice! When installing polyethylene foam pads, the joints must be glued with ordinary or masking tape on both sides. A foil substrate - with aluminum tape.
Extruded polystyrene
Such a substrate for a laminate is the best solution in terms of its properties and pricing policy. This material has the following characteristics:
It is produced in the form of sheets, often a greenish tint. Also, on the basis of extruded polystyrene foam, such a lining as "Isoshum" is known, which is used as an excellent soundproof damper for laminate flooring.
The only disadvantage of this substrate is the high toxicity of smoke during combustion, which makes one more attentive to fire safety.
cork material
The lining made of crushed natural cork tree bark is the most environmentally friendly material of all manufactured linings. In addition, it has such positive characteristics:
Among the shortcomings it is worth noting:
- Afraid of moisture.
- Pretty high price.
- High demands on the surface of the subfloor.
Advice! If you decide to lay a cork damper, then it is necessary to lay a layer of waterproofing on the subfloor (especially concrete). Rolled polyethylene film is suitable for this purpose.
Varieties of cork substrate
Several varieties of this material are also produced, for example, bituminous and rubber-cork linings, each of which has its own nuances:
- Bitumen-cork material has an increased waterproofing property.
- The damper based on rubber and cork has a pronounced depreciation characteristics.
Common to these materials is the fact that it is not recommended to mount them on underfloor heating.
coniferous material
This laminate substrate has appeared relatively recently and reviews about it are mixed. Someone praises, some scold, and we will figure out what technical characteristics it has. Let's start with the positives:
- The environmental friendliness of the material is beyond doubt.
- Large thickness (5–7 mm) contributes to excellent leveling of the subfloor.
- Good heat and sound insulation abilities.
- When wet, it does not lose its properties and retains its shape.
It is worth noting that such a substrate is produced in the form of green mats, which break and crumble quite easily and often.
Advice! In order not to spend your money on a low-quality product, you should consult with the seller about the product warranty. How better material the longer it has a warranty period.
Other materials
Other types of linings are also produced, among which the following materials stand out most noticeably.
fiberglass damper
Although this lining material does not have pronounced flaws, it is rarely laid under the laminate. Among the advantages are:
- Increased strength to various influences, which has a positive effect on the resistance of the material to deformation.
- The environmental friendliness of such a substrate allows it to be used even in a children's room.
This rolled underlay is optimally combined with the thin look of the laminate and laid on a pre-leveled subfloor surface.
Underlay for quick laying
A unique lining is also produced - an accordion. All sheets of this lining are fastened together and stretched like an accordion. This laminate underlay allows you to quickly and easily install any floor covering. This material has the following properties:
- High density, as a result of which the damper does not sag or compress.
- Excellent water-repellent characteristics are combined with the ability of the material to pass air. This allows the laminate to "breathe".
- Acceptable soundproof performance.
- Ease of transportation and installation, because the packaging does not take up much space.
In addition, the accordion pad has a special corrugated packaging, which not only makes it easy to transport and store long time material, but also clearly demonstrate all its advantages.
Advice! For each type of laminate, the manufacturer most often recommends a specific damper. It is important to read and follow these guidelines. In case of gross violation of the instructions, the manufacturer can even remove the warranty period from their products.
Having studied what laminate substrates are made of, you can choose exactly those damper specifications that you need from the whole variety of materials. A wide range will allow you to make the right choice without much difficulty.
