What substrate under a laminate is best suited for your base because of its practicality and durability of laminate flooring, these subtleties and discuss in this article.Laminate as construction and decoration material, now at the peak of popularity.After all, it is quite durable and perfectly suited as a floor covering.

Furthermore - laying laminate under force even to those who neiskushen in these cases and do not come across before with this material.What can I say - the laminate has several advantages over other materials.

Why do we need the support and what is required of him?

must be remembered that in order to laminate flooring was

really beautiful, before laying the material necessary to achieve almost perfectly flat surface of the base on which will be laid laminate.It may seem that there is no simple task.IeIt is enough to achieve a smooth surface of the base and start to lay laminate floating method, which yields a "monolithic board" is not associated with the base rigid manner.

However, not all so simple.Try a walk on this floor in shoes with heels as you can hear a loud clatter, as if was not a man and a horse.The service life of this coating is long, 2-3 months in the seams of the laminate will play, and then the floor will start to sag and just knock on the ground.

To prevent such a mishap is usually placed under the laminate substrate whose thickness is in the range of 2-4 mm.The support is intended to smooth out irregularities in the substrate, to be something of a shock absorber between the laminate and the screed, as well as dampen noise, which begin to appear when walking on the laminate.

To date, the majority of porous substrates for laminate and are afraid moisture.The only exception is Tupleks and mastic asphalt.If the substrate is laid on plywood sheets, the extra-proofing is not necessary.If the parquet and laminate flooring laid on the screed, in view of the temperature difference on the screed begins to appear condensate.In this case, it is strongly recommended to enclose a substrate PVC film thickness of not less than 0.2 mm.To determine which substrate is best for laminate consider technical specifications, as well as the advantages and disadvantages of each type of substrate.

substrate made of polyethylene foam

foam polyethylene - the material is fragile and if it is a long time under load, it tends to be compressed.Polyethylene foam sold in rolls.In general, this material is considered to be the cheapest for the substrate and very easy rushing.

After about 10 years of polyethylene foam is starting to disintegrate, and it turns out is not material to the substrate and the powder that bad "holds" moisture and transmits heat.And if we add the fact that these rolls may lie in warehouses for two years, waiting for a buyer, the remaining service life even less.By choosing a material for a foamed polyethylene substrate, it is necessary to pay attention to its density.If the density is good, hence the quality of its on height and lifetime will be long.

Like any material from this type of substrate has both advantages and disadvantages.

+ The advantages of polyethylene foam include:

  • it water resistance;
  • has good sound insulation characteristics;
  • fit easily and quickly;
  • polyethylene foam strips are joined together with adhesive tape;
  • cheap.

- However, this material is not without disadvantages.These include:

  • weak mechanical strength;
  • compaction under heavy loads.

Polystyrene as a substrate

Polystyrene has almost the same characteristics, that is polyethylene, but some options are many times better.Polystyrene thickness of 3 mm and is typically used as a substrate in the houses where the floor covering must have higher insulating properties, such as a private house.Polystyrene sold plates whose dimensions are meter-to-meter.In a pack of 10 sheets typically polystyrene.

In some cases a polystyrene substrate has 2 layers.The first is polystyrene, and the second - aluminum foil.These layers are joined together.During installation it is necessary to make sure that the foil was always on top.Compound sheets, in this case, the adhesive tape is made of foil.

+ The advantages of polystyrene include the following:

  • it water resistance;
  • put him easily and quickly;
  • has good sound-absorbing and sound-absorbing properties.

- However, there are the following disadvantages:

  • when applied to polystyrene excessive force, it can be easy to break;
  • under heavy loads polystyrene simply pressed and loses its characteristics.

cork backing

Such substrates are usually made of balsa wood chips, extruding them.This environmentally friendly material becauseNo harmful components therein is not.Probably for this reason, the material for the substrate is the most expensive among all known.But, being a laminate, such substrate is not pressed, and its sound insulation and thermal insulation characteristics, one of the best.Cork may be sold as a substrate in the form of plates and in the form of rolls, which allows the acquisition of this material to reduce costs and thereby save money.

+ Its benefits include:

  • easy packing;
  • good thermal insulation characteristics;
  • ecology.

- However, it has the following disadvantages:

  • increased moisture is fatal for him, from her this stuff just starts to crumble;
  • cost cork backing can be great for some.

Rezinoprobkovaya substrate

It is a blend of synthetic rubber and granulated cork.According to some information, this material is several times better than cork backing in terms of soundproofing.

Bitumen cork backing

to submit the material, just look at the Finnish material Parkolag by ICOPAL, whose base is composed of kraft paper impregnated with asphalt and the subsequent spilling crumbs cork.This material must be laid cork pouring down.So it is possible to provide micro ventilation beneath the substrate.In other words, this layer prevents the formation of moisture.If such a substrate, the extra waterproofing to do.

It is a composite material with a minimum thickness of 3 mm, which is made in France.Structurally, it has 2 layers of PVC film, which lie between the polystyrene beads.All this is covered by high-strength polyethylene, which is designed for heavy loads and protects the laminate from moisture and dirt.The bottom layer is also covered with polyethylene, but not so strong.But it has a lot of micro-holes that absorb moisture in the volume space filled with polystyrene beads.

It's pretty good stuff, which perfectly absorbs noise.Laying it fast and it can be used in the organization of underfloor heating.It must join with only one hand, using a special overlap, which is applied spetskley.This material is not subject to deformation, but very afraid of moisture.

substrate based on bitumen

Despite the fact that this material can be called new in the construction market in Russia, but its active promotion has already begun.Its advantages include heat, noise and moisture barrier.All this of course is good, but it has one very serious drawback, which is that the mastic asphalt, the underlying substrate that is a "hotbed" of formaldehyde.That is why this material is prohibited in many countries.It is interesting that our domestic manufacturers are silent this fact.

Which substrate is best suited for laminate?

So, how do you determine what kind of support under the laminate is better to use and which parameters to pay priority attention.How can I trace the deficit under the laminate substrates for the moment there is not expected.Maybe that's why the right choice of the substrate is not easy.So, for the correct selection of the substrate must take into account the following parameters:

  • simplicity of its installation
  • long life
  • not too high a price with good quality

With respect to such parameters as the thickness of the substrate, there is in order to avoid excessive depreciation andsagging fabric sent experts recommend the use of a substrate thickness of no more than 2 - 3 mm.

also need to know that quality substrate as an intermediate material that is able to increase the service life of the laminate.Whatever modification of the component composition had a laminate panel, will it include polymeric additives or include fiberboard or MDF, in any case, it is the floor covering can be attributed to the wooden floor.That in turn means that it is necessary to ensure certain conditions installation, which are dependent on the substrate.
