Sandwich panels: How not to make a mistake in choosing?
Thanks to their multi -layered composition, such panels are very popular all over the world. Recently, more and more often they have been used in our country. Depending on the filler, the price of a sandwich panel is determined.
If the sheathing is practically unchanged – a sheet of steel with a protective coating of polymers, then the filler options are not so few. It is he who isolates the structure from heat, noise and sound.
To cover steel, polyester, playsol, or polyvinylenflufluenftoride is used. Thanks to it, the metal is protected from corrosion, ultraviolet radiation and becomes wear -resistant.
Panel lining
Using sandwich panels in buildings with the need for thermo and sound insulation-this is just a find. Moreover, they can be used in the construction of multi -storey buildings, because the length between the supports can be quite large.
They can be made of metal, waterproof plywood, as well as PVC, fiberboard and other materials. For the construction of a house, thermal insulation panels are best suited, consisting of chipping plates and a layer of polystyrene foam.
Filler
How to find and buy sandwich panels with thermal insulation and water resistance? Easily. Foam polysterol, which is used as a filler, is characterized by breathability. In this case, moisture is not allowed, which avoids the appearance of condensate. So, even in a house made of wood will be provided with dry and clean air.
With its help, protection against moisture penetration is ensured, and accordingly dampness is never formed, the consequences of which are well known to everyone (mold, rot, fungus). The service life of this filler is quite impressive – at least forty years.
The fact that sandwich panels are made only from the foam of the polystyrene that self-adjusts is also made and also important. So, you don’t have to worry about his fire safety. The resistance before fire reaches forty -five minutes even if the interior wall decoration is carried out using drywall.
Sandwich panels have enviable strength and resistance. It is thanks to this that their use is allowed both as fencing and bearing elements. Their reliability is checked even where the danger of the appearance of a tornado is constantly. And this is a fairly important factor if the acquisition of a sandwich is implied for the construction of walls (both internal and external) and ceilings.
