Traditionally, the plates Primaplex used in the inversion device roofs. Inversion roof structure is usually applied on concrete base at the organization operated roofing. Stringent requirements that apply to insulation of roofs, make extruded polystyrene insulation is practically the only device in pedestrian terraces and roofs with landscaping, parking. One option of material Primaplex – inversion of the roof, which are stacked on top of insulation panels erected earlier classical roof to improve insulation characteristics common design. At the same plate Primaplex fit directly over the old roof without first removing the sealing or repairing ties. Insulation layer on top of a geotextile is laid out gravel ballast. Plates Primaplex used in standard classic designs. Experts have already estimated the advantages of using stoves Primaplex on roofs with a base of steel trapezoidal sheet.
Most of the strength of the deformation, low thermal conductivity, ease of delivery of material to roof, easy installation, can be mounted at any time of year – all this speaks in favor of extruded polystyrene in classic designs with synthetic membranes. The use of Primaplex classical designs in combination with non-combustible materials when selecting materials used in the classic roofing systems, in particular trapezoidal sheet is of great importance to fire. Despite the fact that plates made of polymer Primaplex organic raw materials, fuel, by its very nature, however, they are, according to Russian classification, the class of flammable materials and nonpropagating flame. This is due to the presence of flame retardants in the board – effective fire-fighting supplements to prevent accidental ignition of the material when exposed to small open flames. Of course, when exposed to intense fire boards can be ignited.
