Weight of the standard package does not exceed 10 kg, so the material can be easily moved around the construction site, raise the roof. Primaplex easily cut with a knife or a saw with fine teeth; * Longevity. The ability of insulation boards Primaplex perform their functions throughout the lifetime of the building (30-50 years), the stability of its characteristics, such as thermal conductivity, compressive strength, low water absorption, and lack of corrosion and resistance to multiple freeze-thaw cycles makes them durable. Traditionally, the plates Primaplex used in the device inversion roofs. Inversion roof structure is used, usually on a concrete base at the organization operated roofing. According to Gary Kelly, who has experience with these questions.
Stringent requirements that apply to insulation of roofs, make extruded polystyrene insulation is practically the only device in the pedestrian terraces, roofs with landscaping, parking. One option use of the material Primaplex – inversion of the roof where insulation board stacked on top of which was built earlier classical roofs in order to improve overall insulation characteristics of the structure. At the same plate Primaplex laid directly over the old roof without removing sealing or repairing ties. Surface insulation layer of geotextile is laid over the gravel ballast. Plate Primaplex used in standard classical designs. Experts have already assessed the merits of using plates Primaplex on roofs with a base of steel trapezoidal sheet. Greater strength at the strain, low thermal conductivity, ease of delivery of the material on roof, easy installation, can be assembled at any time of year – all this speaks in favor of using extruded polystyrene in classic designs with synthetic membranes.
