Select and put the cork under the laminate substrate
to laminate lies flat, and it did not break the locks, and the board did not creak under it enclose a substrate made of a special material.Good substrate and make the floor warmer, and will help the absorption of extraneous sounds.For example, very well demonstrated cork underlay for laminate, which will be discussed below.

substrate Cork: properties and types
One of the undoubted advantages of such a substrate is environmentally friendly.For its manufacturing compacted under pressure finely chopped bark of the cork tree.This crust contains natural glue - Suberin.He firmly connects the pieces of cork, and the material becomes uniform.There is no "chemistry" in it is not contained, so the allocation of poisonous substances can not be.
And cork backing kee
- density - from 220 to 260 kilograms per cubic meter.
- Humidity - not more than 7 percent.
- Thermal conductivity - 0,043 watts per square meter per Kelvin.
- sound absorption coefficient - 0.85.
- Resistance to fire - high.Lights tube with difficulty, and toxins during combustion does not emit.Outside fire resistance (ASTM) - C -209.
- Breaking strength - 2 kilograms per square centimeter.
substrate can be made not only completely out of jams, but in combination with other materials.Consider these options in more detail.
Bitumen cork backing
to take its manufacturing cardboard or heavy paper, one side of which a layer of bitumen.On the opposite side there is a layer of cork.Through this structure, the substrate is not only protected from moisture, and outputs the excess moisture from the laminate.When it is not necessary to arrange laying of additional waterproofing.By the way, this substrate is always put down a layer of cork.At the junction of the sheets it glued tape of sufficient width.
Plus this material is that it absorbs sound better than others.For its production of finely ground mixture of compressed cork and rubber (synthetic).Such a substrate as the previous version, is considerably more expensive than the material made entirely from cork.Therefore, in an apartment of their use is not very practical.
How thick substrate to choose?
Many mistaken, believing that the best choice would be the thickest substrate.Base with defects such as pits and bumps and a thick substrate to align fail.Only with the help of pre-screeds, self-leveling floor or plywood flooring, it is possible to solve this problem.

With regard to protection against noise and heat preservation, then a thick substrate, these figures better.True, there are nuances.
When the substrate has a large thickness, it is deformed and more.This is fraught with the advent of depressions in areas where the load is large.Well, as far from dents and damage to the locks of laminated boards.The best option: cork underlay for laminate - two millimeters.
How to style cork backing
After unpacking the material should be left for 24 hours in the room where it is supposed to change the flooring.This is done in order to plug "get used" to the temperature and humidity environment.Then you can start packing and - first substrate and then laminated.That they are not displaced relative to each other, the substrate is positioned transversely laminate flooring planks.
First of all, we clean the subfloor, if necessary, correct all the irregularities putty composition.If the floor is concrete treated it with a special soil, protects against fungus.Otherwise, that and look - mold appears.
order to protect from moisture take a film of polyethylene.It is cut into strips of desired size, leaving an allowance of 3 centimeters.The edge of the film should extend over the wall at 1 or 1.5 centimeters.The overlap between adjacent sheets of film making 10 or 12 centimeters.To connect them using an adhesive tape.In order not to ruin the waterproofing Never use staples or nails.
stepped back from the wall 1cm, put the first sheet substrate.
Due Date to the first sheet (no overlap) laid next sheet.Adhesive tape to connect them should have a width of 6 centimeters.The last bit of leaf crop, the distance to the opposite wall and was 1 centimeter.
If you stacked laminate wood floor, it is not necessary to produce waterproofing, a plank on the base substrate.
Important: never put two layers of the substrate.Features of this does not improve, but it will wear out much faster.And again, a wholly-owned cork is only suitable for the living room or hallway.The kitchen is better to use a waterproof material.For example, a substrate composed of a combination of cork with bitumen.
Well, now that the styling is completely made of cork under the laminate substrate, and he can begin to lay the laminate.
Choose and laminate, and the substrate is necessary for him according to their own tastes.Another important factor is how much money there is in the wallet.And if you decide to fork out for an expensive laminate, remember that it will last for a long time only with a good substrate.And if it is made of cork, it is about the safety of the flooring will not have to worry about for years to come.Although cork backing can not be called cheap, but the money spent, it paid off.
