Sandwich panel 18 and 25 mm made of an insulating component in rigid polyurethane foam and sheathed on one side with galvanised sheet and on the other side with pre-varnished galvanised sheet both 0,5 mm thickness. The density of the panels foamed PUR is of 45 kg/m3 with a tolerance of ± 2 kg/m3 (UNI/EN 1602).
Thanks to the high number of closed cells, exceeding 95%, the foam of the panels has a coefficient of initial thermal conductivity, measured according to UNI 8302 std, of 0,024 W/m°C at the temperature of 10°C.
