many, going to change the flooring, laminate to stop - and it is not very expensive, and looks better than the parquet, and serves regularly for many years.But there is one important point - you need to choose a laminate, which complies with the conditions of use.Just about the technical characteristics of the laminate will be discussed in this article.

What is laminate flooring and how his device

This flooring can often be very similar to the floor, a massive wooden board, a ceramic tile.Some manufacturers produce a laminate "under the skin", "under a rock", "under the metal."Over time, perhaps, there will be even more interesting species.

There is a misconception that an inexpensive laminate floors in all quality par

ameters significantly inferior to the parquet floor.But this opinion is erroneous.After all, the creators of the laminated cover just wanted to save him from some of the shortcomings inherent in the parquet.By the way, they have it bad happened, but the technology HPL, used at the beginning, turned out to be costly.Therefore, the first time the price of the laminate were high - only at the end of the last century thanks to the appearance of DPL technology of its production was more budget.

device board laminate material

this multi-layered - or rather, four-layer.If you take a cross section of the board, you can see the following components:

The device layers of the laminate board

1. The lowest layer is called stabilizing, because it increases the rigidity and protects the board from damage, without letting it deform.Sometimes under this layer there is another - acoustic, but with such a laminate substrate is produced only in a number of collections.

2. The middle layer is called the carrier - he is the main part of the structure.Its quality depends on thermal and sound insulation properties of the laminate, as well as its ability to hold water.Made carrier layer of HDF - dense fiberboard.A distinctive feature of this part of the board that it is located on the lock to connect to other boards.

3. Next, moving higher, we'll see a decorative paper layer.His drawing determines what will be like flooring - on wood, parquet, stone or ceramic tile.

4 .The top layer is called protective - he does not give the laminate rapidly deteriorate and spoil from the blows.This coating consists of an acrylic-based resin or melamine.The thicker it is, the higher the grade laminate showing its resistance to wear.Modern design manufacturers have made adjustments to this layer.Now it can be not only protective, but also and decorative.For example, to simulate the maximal tree may be marked irregularities.

locks laminate Click and Lock: compare and their characteristics

Who adhesive laminate virtually placed - it locks much easier.Applying them, not only can quickly assemble flooring, and disassemble it easily.But such a need may sometimes arise - for example, the need to change the floor when you move.This dismantling of the laminated cover will not cause problems, and all boards will remain intact.

laminate produces a large number of producers, and each of them has its own system of interlocks.But you should not be afraid of it - because of the principle of work they are divided only into two groups: Click and locks Locks Lock.And now tell you more about each of the two types.

Lock lock for laminate

1. Lock Lock - latch with a spike and a groove.Castle-type lock is called the pile.It is very simple in construction and economical.Such a compound is used for a long time, so many consumers choose a laminate with him.

principle of its operation is that in the groove, available on a laminated board, a spike is inserted, acting on a nearby board.For the strength of the joint is equipped with a spike combs, which are held in the groove, firmly locking the lock.Glue is not needed, and all so well kept.

pile called the castle of the fact that when laying laminate board hammer at each other, their pristukivaya wooden or rubber mallet.But better that it makes the master - professionally laid laminate flooring last longer.However, in this connection consumers usually do not complain - it is sufficiently reliable and long-lived.Although shortcomings latch locks also not deprived.

Most of all do not like locking-type lock constant load on the floor.After all, at the same time and tenon and groove included in the compound, rub against each other, gradually istirayas and thinned.Inevitably there are cracks, then the lock will not be restored.But laminate manufacturers are trying to fix this flaw - everyone uses it for his own method.

Slick lock for laminate

2. Castle Click - suitable for non-professionals.This lock connection is collapsible.It came later than the previous one, regardless of the more "advanced" and quality.DIY particularly pleased that such locks could handle even a person with no experience.

ease of assembly and disassembly allows quick and excellent result.So - do not necessarily call professionals for laying laminate.Manage on their own, at the same time you can save.

Works click lock type as follows: docked at an angle of 45 degrees two laminate planks need to gently press the lock connection.It snaps into place without much effort.It is very convenient, you do not need any lock mallet rap, nor even any instruments used.Everything is done by hand, and it is easy and fast.And the disadvantages of the previous lock is eliminated - at a load of friction is not observed, since the compound undergoes compression.Accordingly, it becomes even stronger.

understand the technical intricacies of the laminate

inspected and tested the material in different ways.For example, in Europe, made to follow the standard EN 13329 - Laminate floor coverings - Specifications, requirements and test methods (multi-layer coatings for floors. Specifications, requirements and test methods).In accordance with these standards is supposed to check the following features laminate:

  • Abrasion resistance (otherwise, abrasion resistance);
  • ability to carry long loads and heavy blows;
  • resistance to temperature increase (the material should not deteriorate when in contact with hot objects - such as a lit cigarette);
  • resistance to delamination and anti-slip;
  • color fastness;
  • no stains on contact with chemicals used in everyday life;
  • antistatic properties;
  • levels of formaldehyde;
  • speed and magnitude of the swelling when wet.

Upon successful completion of all tests laminate, fully conforms to EN 13329, to be labeled.Include the following basic parameters:

  • room standard to which the test material;
  • the manufacturer;
  • name of the product;
  • color number or the name of the figure;
  • batch number;
  • grade laminate (21 to 33);
  • one board dimensions in millimeters;
  • number of boards in one pack;
  • coverage area.

What classes laminate and Association EPLF

To classify laminate flooring is used all the same European standard EN 13329.

It identifies the following classes of laminate:

Classes 21 to 23 are only suitable for usein an apartment or house.Now they have stopped releasing due to low strength.

Class 31 also designed for domestic use.

Class 32 can be used in the rooms of the apartment, where there is an increased load (entrance hall, kitchen, hallway).This laminate is suitable for office space with a small cross.

Class 33 for public, office and industrial premises.Able to withstand heavy loads.

Class 34 - especially durable coating (sports), has a high resistance to abrasion.

right to belong to a certain class of products receives only those producers who are affiliated with EPLF - European Producers of Laminate Flooring.In Russian abbreviation is written this way: AEPLNP (Association of European manufacturers of laminate flooring).And if the manufacturer is not included in this organization, the class specified on the packaging often does not correspond to the technical characteristics of the laminate.After testing properly (in accordance with European standards) have been conducted.So it turns out sometimes that the specified class of 32, or even 33, but in fact this cover does not hold up to class 22.

A similar dishonesty sin not only many Chinese manufacturers, but also some Russian.If you go into a huge construction hypermarket, it certainly can be seen in the windows of its laminate class 33 and a thickness of 7 mm.It would - nothing special, but this fact shows a clear discrepancy standards.According to European standards, this class laminated coating should be at least one millimeter thickness, t. E. 8 mm.

And to avoid such incidents and not to be deceived even in the details, check out a list of producers, members of the association EPLF.Details - here: is the site of the organization.

Here is a list:

But it should be noted that the separation of the laminate classes - it is relative.For example, in Austria, Germany and Belgium, wear resistance determined by the index of speakers, demonstrating the strength of the protective layer of the laminate.The classes themselves laminates exhibit the density fibreboard HDF and its resistance to corrosion.Therefore, on the label to the value of the class (31 to 34) will certainly add value AC.If you see in the store laminated covering class 32 index AC5, we must understand that this material is intended for residential applications with a high load.

Manufacturers from China are trying to wrap this ambiguity in their favor - they show only the class, and nothing more.But class 33 may have a different protective coating - from AC3 to AC5, but this is not the same with respect to durability.From the side it seems that a laminate with different indices of the AU absolutely identical, but in fact it turns out that the life they have different.

on to talk about the three main characteristics that are worth paying priority attention, choosing laminate flooring for the home.

These are the "three pillars»:

wear resistance


resistance to moisture




Durability laminate

As mentionedNow laminate is produced four major classes: 31, 32, 33 and 34. It is believed that the class is suitable for 31 bedrooms, 32 class - rooms for those apartments, where the load on the floor more, and 33 and 34 classes are used in areas such as commercial.However, this division is still somewhat superficial - you need to look more deeply.For clarity, we consider how the test laminate, check for wear.Sample

laminated cover attached to a special device and then act on a rotating abrasive disk.First, measure the speed at which the coating is scratched.After a while, the protective coating will be erased completely and the number of revolutions is measured again.Adding the two measured values ​​is the mean value - this is the wear resistance, which is indicated in revolutions.Here are some examples.

assume that scratch the protective coating abrasive may within 200 rpm, and for the complete destruction of his grinding wheel have to rotate longer - about 4000 rpm.We get an average value equal to 2100 RPM.And other brand of laminate may have different values: scratches appear after 1200 revolutions, and complete erasure - through 3000 rpm.The average value is the same again - 2100 rpm.It turns out that both of wear resistance of floor coverings are of the same class.However, in the first case, the laminate is scratched faster - because it does not have a protective layer composed of corundum, which prevents scratches.An increase in the thickness of the melamine can reduce abrasion.

but adds corundum quite expensive, and therefore you can find laminate class 32, which is more expensive than that of the 33 classes.And if, tempted by the low price, the landlord will choose a budget option for Class 33, that soon he may regret it.Sex too quickly scratched, lost marketability.But to remove the flooring will be a pity - because its top layer for a long time will not rub off.It happens that another 10 years people use such flooring - solid, but having a completely unpresentable form.

can imagine and more development - buy laminate class 32, more expensive, having a part of corundum.Such a floor for a long time not lose the appearance, but it must be remembered that it is inferior to the material abrasion class 33.The apartment has a laminate would have "to the court", after serving 15 to 20 years, and long remain attractive.And here at the hotel or store where there's a lot of people, he quickly goes down - rub.

Practice shows that in residential areas 32 and 33 classes of laminates show approximately the same durability.After all, in all respects, except for resistance to wear, they are very close.In particular, HDF plate and of a different class and has similar characteristics.And she, by the way, wear out faster than a solid protective coating (which is in the apartment starts to wear off no earlier than in 15 years).

note that the characteristics of the laminate by class, according to EN 13329, include a few important parameters.This, in particular, heat resistance, moisture resistance, shock resistance, which will be discussed hereinafter.Just note that the standard laminate, produced in China and Russia, have such severe restrictions.After all, these two countries are not members of the association EPLF.

Durability laminate

strength and moisture resistance of the laminate - from which they depend

HDF board with carved locking compound - the main element of the laminate board.It is a large share of the cost of the laminate.The denser HDF plate, the less wet laminate, are the longer and stronger hold interlocks, preventing the appearance of cracks between the boards.It is also important, so precisely manufactured plate, whether she deviations from geometry.If all the dimensions are met "on the nose", the laying laminate will not be particularly difficult, and subsequently formed the slot.

for its quality, of course, have to pay.So often in DIY stores can see several brands of laminate of the same class, but at different prices.And the difference between these prices may be even several times.

Many believe that the wax coating on the locks - this is all that is needed to protect the laminate from moisture.But it is not - in this case, moisture-resistant material can not be named.Although the benefit of wax treatment brings hope but it is not necessary.It merely postpones the moment when the water enters into the material.And if you take a normal (not waterproof) laminate and leave it in a humid room, the waxing will protect it from the water for only a few minutes.A otpilivaya pieces of boards during installation, we leave them without protection at all.

real reason for impregnation ends waxed boards - relief laying laminate.It was not clear moments?
