-Contribution of the PIR-ALU to the "Ideal Duct":

Long-Life Materials

Weight

-The PIR-ALU pre-insulated aluminium panels is compound for two materials:

·External protection: foil pure aluminium embossed in both faces 

·Inside insulation: PIR rigid foam

-Both materials are unalterable in the time and they don't suffer any type of environmental corrosion neither aging

-Light, but very resistant:

·PIR-ALU 20/35 (20mm): weight 1,1 kg/m²

·PIR-ALU 30/35 (30mm): weight 1,4 kg/m²

·PIR-ALU 20/45 (20mm): weight 1,3 kg/m²

-It is equal at 1/6 of the weight of the sheet metal (GI) ducts without isolation

-Easy to transpot, to handle, to build and to install

-Economy of supports: one each 3.000mm
