Polyfoam, which has its own qualities, provides high thermal insulation in the house. The main ability is persistent endurance, it is able to withstand high mechanical overload. This gives the foam a chance to participate in construction. Expanded polystyrene in the recent period is gaining popularity among construction companies. This material can act not only in the role of low-rise construction, but also as internal thermal insulation, as well as in monolithic construction. There is a possibility of using expanded polystyrene foam, which has a low density and does not change the load on the foundation over time, for the reconstruction of old brick, tile and wooden houses.
To the outer turn of the wall, plates (heat-insulating), are attached using mounting devices or glued. This material requires careful handling, allowing an open flame will not lead to anything good. For such purposes, non-combustible materials are used: tiles, bricks, steel or aluminum profiles, etc. An excellent effect is achieved when using foam Plex for thermal insulation of walls (from the inside). In such cases, noise insulation qualities are also noticed. The comfort in the room is noticeably increased. The thickness of the expanded polystyrene plates on average ranges from 30 to 40 millimeters into the wall cavity, of course. These slabs are easily anchored using the most common wall anchors from 400 to 500 millimeters on a vertical surface and from 900 to 1000 on a horizontal surface..
There is another option, it consists in attaching these plates to the outer surface. Recommended values for installation are from 51 to 81 millimeters. In such cases, the boards are fixed with adhesives or standard mechanical fasteners. In the same cases, cladding will not be superfluous. For internal installation, plasterboard cladding is required, or plaster for external installation: plaster with two cement layers of mortar, applied to a metal mesh.
The above plates will perfectly insulate the floor of your home. In this case, polystyrene foam tiles are laid on a layer of some material with insulating properties. After sealing, tongue-and-groove wood particle board, concrete mixture with a thickness of 6 to 8 cm are laid on top.
