This product is the cheapest and lightest facing, exclusively proposed for low thickness insulation polyurethane boards. It is basically closed, therefore, in order to limit the creation of blisters and to allow the discharge of blowing gas in excess, punching the facing itself, with a spiked calander, is recommended once the panel has reached the exit of the double belt conveyor.
PACO, available in 400 g/m2 or 500 g/m2 versions, it is the ideal facing for panels meant for roof insulation and for the insulation of attic floors with insulation material between concrete slab and bearing structure. The so-made panel is also used in the separation of cold basements and heated residential rooms.
