The foam due to its physical properties, is a very good heat and sound insulation material. Physical properties: It consists of a ball and each ball is constructed of thousands of cells filled with air. The air enclosed in the cells can not move, and the still air is the best heat insulator. The air is not less than 98% of the foam. Polystyrene balls filled with pentane (pure hydrocarbon) which is a foaming factor, and heated by steam, resulting in changes in pentane volatilize and expand. Under pressure of polystyrene beads also expand, resulting in the formation is familiar polystyrene beads, increased the volume of plates, at least 50 times.

Cells in each expanded plastics balloon filled with air and become elastic, and then stick together under the influence of steam, forming light, uniform, resistant to compression and retains its insulating material dimensions. Almost every one of us once met him, whether in children's games, whether already in adult life. The foam is not sensitive to moisture material does not emit any harmful compounds. It belongs to the so-called "monomaterialam" (consisting of one type of material), and therefore it is ideal for 100% utilization (recycling). In construction, the foam used in as insulation for different designs.

In the production of polystyrene spent relatively little energy, and its insulating properties can save a significant amount. What and How glue foam? Expanded polystyrene is gaining popularity due to its characteristics. Foam is used in many types of structures. There are many ways of fastening the foam – investing in the crate, flooring surface, bonding and mechanical fasteners with anchors, fungi, studs, etc. To glue the foam can be virtually any adhesive. It can glue front bytmorozostoykie TM 'Budmayster' postmark for fixing ceiling tiles, liquid nails TM 'Den Brauen', time-installation, sealant 'Den Brauen', preparations for tile TM 'Budmayster', as long as the adhesive does not contain in its composition of organic solvents (benzene, acetone, esters, etc.), as these substances can dissolve styrofoam. These solvents may be contained in the bituminous mastics, for example. Glue the foam can be almost any material – brick, concrete, drywall, osb, plywood, magnesia sheet, galvanized iron, steel, and many others. For greater reliability, you can use nail-fungus – dowels for insulation. For example, in the case of facade insulation, foam mounting adhesive on solutions, each sheet of foam (50×100 cm) fastened in the middle and at the corners, with the capture of a hat mold adjacent sheets. Next on the foam applied reinforcing mesh and plaster. Related Products, which are effectively marketed with foam: front adhesive for polystyrene, for insulation anchors, anchors, reinforcing mesh, plasters, putty knife, decorative plasters.
