It is no secret that many rooms in the house have excess humidity that floor does not make favorable impact on walls, ceiling and, of course. Floor is exposed to the strengthened influence as, damp cleaning is done, at least, once a week.
To equip flooring when humidity high, rather not simple task. If the decision floor is made to close laminate, then it is necessary to get acquainted with criteria of water resistance of material in detail.
The basis of laminate is formed by the HDF plate made with use of wood fiber. Wood fibers fix in form by means of the fastened formaldehyde resin. Availability of binding components does not assume hit of moisture in inside adherend plate. But water as speak, sharpens stone therefore among fibers it can find the thinnest courses too.
Floor types of waterproof products
There are types of coverings which are resistant to moisture:
HDF - panels have density up to 900 kg/m3. Such density allows to contact to water three hours without destruction consequences. But more than this time the covering will not resist – after drying-out it will undergo deformation.
PVC laminate is not what other as plastic panels. Feature of their material – lack of susceptibility to moisture. Such panels have also high heat and sound insulation as are executed in the form of hundreds with emptiness from airbags.
HDF – panels with strengthening. Have the increased level of content of resinous substance. Water is kept by nearly 6 hours. But after this time begin to bulk up, and then when drying also change form.
Remember that weak spot of panels are connecting "locks" which are processed on the machine and have weak moisture resistance.
As well as what to choose
There are factors which define degree of protection of products:
- pitch impregnations,
- paraffin protection of castle system,
- strengthening by pitch of the lower and top layers.
The low-quality products should not even be considered. It will want to undergo to nobody anew in several months the procedure of repair of floor.
Upon purchase it is worth paying attention to means of the increased protection to moisture at each type of the pleasant laminatny plates.
It is possible to execute the simple test - to measure thickness of sample of product and to put it in water for 6 hours, and then to check, the product became how thicker. Thickness should not become more, than for 18 percent.
