A heavyweight reinforced vapour control layer with aluminium faces and good fire resistance properties. The multifilament polyester scrim reinforcement gives good resistance to tears and punctures. The exposed aluminium foil on both faces gives a high water vapour resistance and ensures low flame spread characteristics.
