Pre-insulated foam Panels

Description

Sandwich panels made of an insulating component in rigid PUR / PIR foam and laminated on both sides with embossed aluminum foil. These panels are suitable for the construction of air distribution ducts in air-conditioning and heating systems. The standard production thickness is of 20.5 mm & 30mm with a tolerance of + / - 0.5 mm (within the tolerance foreseen by ISO 1923 standard). The standard production length is of 4000 mm with a tolerance of + / - 5 mm (within the tolerance specified by ISO 1923 standard). The standard production width is of 1200 mm with a tolerance of + / - 3 mm (within the tolerance specified by ISO 1923 standard). The squaring operation is carried out with an accuracy of + / - 30°C. The fabricated duct can withstand a pressure of 1700 Pa. The rigid foamed PUR / PIR of which these panels are made is a result of a chemical reaction between specifically formulated, first quality polyols and isocyanates. The polymer obtained from the specific reaction (which involves the transition from the liquid to the solid state) is physiologically and chemically inert, insoluble and unable to be metabolized. The density of the panels with a thickness of 20mm foamed PUR / PIR is of 45 kg/m3 with a tolerance of + / - 3 kg/m3 panels with a thickness of 30mm foamed PUR / PIR is of 48 kg/m3 with a tolerance of + / - 2 kg/m3. The sheathing is made up of embossed aluminum with a thickness of 80 μm and 200 μm on both sides of the panels depending on the type: this sheathing is coated with a lacquer based on vinyl resin on one side and on the other by thermo-welding lacquer based on vinyl resin. The panels are antifungal, treated for protection against mold, fungal and bacterial growth. Thanks to the high number of closed cells, exceeding 95%, the foam of the panels has a coefficient of initial specific heat conductivity, measured according to ISO 8302 standard of 0,021 W/ (m K) at the temperature of 10°C. These panels can be used constantly in a temperature range from –30°C to +65°C without any substantial difference in thermo-ventilating insulation specifications. Delivery is made in packs of 10 panels for 20.5mm thick panels and standard packs of 7 panels for 30mm thick, packed with thermo ventilating shrinkable polythene sheets.
