Laminate is a new high-quality coating that meets the many requirements.But to properly perform its functions it will be only when the proper line technology of its styling, which is not only in the preparation of the base, but also the type of backing material.A substrate which select a laminate depends on the subfloor and additional functions.For example, heating.

substrate Purpose

substrate for its intended purpose executes lots of different functions.Although it would seem, the support - is needed in order to put under anything and everything.Not so simple, because the base material can be any concrete, old wooden floor, tiles, etc. All of this requires a certain respectively lamination, but there is one requirement that must fulfill all of them religiously - ventilation..Accordingly, the best substrate for laminate - is the one that provides good ventilation of both the base and topcoat.What is the ventilation, you probably should not specify, but recall will still be relevant.It is necessary to carry out the drying of the coating and sub-floor from condensation, dampness and possible rottenness.Thereby eliminating the possibility of the appearance of mold, mildew and other malice.It is not only damaging to the laminate itself, but also very dangerous for human health, which will breathe these spores malicious entities.

Besides ventilation lining material performs several important functions:

  1. Noise.The second most important feature that more than anything else it is important for a relaxing stay.Laminate is a very dense material, which will be a good conductor of sound, to create on its surface.Due to the dense structure, it will be transmitted to the w / w plate, which is also a good conductor, while a resonator, amplifying the sound repeatedly.
  2. Alignment small irregularities.Any lining under the laminate is soft and elastic at the same time the structure of the material, which makes it possible to compensate for all the pits and projections, creating an ideal front surface.

If you have an unpleasant creaking or flex floor you will help tips to eliminate squeaks laminate.

types of interlining

for sale, there are several types of substrates under the laminate.Each of them has its own specific purpose.For, unfortunately, without paving it is impossible, because it is not the perforated type of sale, and it is not planned to produce.In addition, this floor will not as a decorative and protective coating, and torment for housewives.
So, today in the sale are the following varieties of backing materials:

  • polystyrene;
  • tube;
  • cork rubber or cork bitumen.

most common use of expanded polystyrene is exactly under the laminate.Why?Because it is an extruded closed cell material.In addition, he is one of the cheapest used for sex.It has the following properties:

  • not susceptible to rotting and disintegrating with time;
  • has no interest for rodents and vermin;
  • resistant to moisture.

In addition, polystyrene substrate under a laminate is surprisingly good at trapping heat.Due to the stability to wet environments, it can be used on any basis:. Wood, tile, concrete, etc. naked To increase the effect of heat accumulation and lay the foil layer which reflects infrared rays (heat itself directly) by concentrating them in the inner space of the room.Also
polystyrene substrate does not change its dimensions and thickness with prolonged exposure.This is primarily due to the dense structure, which allows to withstand heavy loads.What makes it possible and necessary to use it in places with high attendance and high noise level, because the porosity of the material effectively isolate the sounds produced when walking on the laminate, even in heels.
next type - the substrate under a laminate cork.It is a material of natural origin and machining.It is an excellent thermal insulator, an even greater extent than the first embodiment.As a material having a sufficiently high longitudinal strength, it will be an excellent basis for a floating floor.It does not lose its shape and does not cease to carry out their direct functions.Cork substrate for the laminate is not affected by the process of decay and mold.As a high-quality material lining of the bark of the cork tree has high environmental performance.This makes it possible to use it in rooms of any type of destination:. Kitchen, bedroom, living room, etc.
Being a good thermal insulator, cork substrate characteristics of aeration is quite low, because of which condensation may form on the bottom surface of the laminate.A second disadvantage of this material is its high cost, which makes it impractical to use cheaper coatings.

next type of lining material is a rubber cork underlay.Due to the technology it has improved performance of air space under the cover and over it.For its production uses kraft paper impregnated with bitumen.In general, this material has good waterproofing properties.On the upper surface of the glued pieces of cork in size from 2 to 3 mm, which, strictly speaking, provides the necessary exchange.At its core, cork rubber is the most suitable material as a lining for the laminate.But there is a drawback that is its high cost.
Considering all of the above options, choose the lining material is not so difficult.But we should take into account the properties of the material for each manufacturing substrate under a laminate, which is better, it will help to understand the parameters of stability and performance.
If properly matched substrate for laminate floor heating is guaranteed.After all, it depends on the health of the entire family.Besides all the above types of substrates can be used in conjunction with underfloor heating systems.
the main criterion in the choice of material is the substrate thickness.From it are directly dependent on parameters such as thermal insulation and soundproofing.

stacking technology

to ensure a comfortable stay and a perfectly flat floor surface of the substrate styling should be carried out by appropriate technology.The first and main condition for laying the material is its location across the direction of the laminate planks.This allows the floor greatest strength and resistance to high loads.The second condition is the observance of waterproofing technology.For this purpose, the substrate must be placed under the plastic film layer, if provided on the substrate itself.Also, very efficient use of the foil.It not only will be waterproofing, but also an excellent reflector of heat.

Foil insulation

Foil insulation

Laying cork substrate under a laminate is perfect without docking it overlaps the edges by gluing a double-sided tape.This tape is glued to the subfloor.Along the edges of the walls is necessary to leave the distance that will be output for moisture during its accumulation under the substrate.This is taken into account when using any of the types of materials.
If you use XPS under the laminate as a substrate, it is necessary to settle the sheets diagonally to the direction of the elements of the facial surface.This makes it possible to counteract the movement of the floor when under load.foam sheets must be stacked in a checkerboard pattern, eliminating the possibility of a match coated joints.The effective thickness of this material is 3 mm, which ensures its necessary stability.
Before laying any type of substrate necessary to line the bottom of the maximum quality.This will have less problems when laying laminate flooring and subsequent use.
Extruded polystyrene substrate under a laminate is by far one of the most popular and accessible thanks to its high performance to mechanical stress on the gripping and resistance to moisture.Its thickness depends on the type of irregularities on the rough field.The more, the thicker should be the material.
