Systems P&R Vapour Control Layer (Pour and Roll)
Systems P&R VCL is a high performance vapour control layer for use in traditional, pour and roll applied built up roofing (BUR) systems. It is composed of a polyester reinforced aluminium core coated with rubber modified bitumen. The membrane has a fine sand finish on both sides to prevent sticking in the roll.
Systems T-O Vapour Control Layer (Torch-on)
Systems T-O VCL is a high performance vapour control layer for use in torch applied BUR systems. It comprises an impervious aluminium core, reinforced with polyester and coated with a specially formulated quick melt SBS modified bitumen. The lower surface has a sacrificial film which rapidly melts during the torching operation.
Systems S-A Vapour Control Layer (Self-Adhesive)
Systems S-A VCL is a high performance vapour control layer for use in self-adhesive / cold applied BUR systems. It is composed of a polyester reinforced aluminium core, coated with a rubber modified, self adhesive bitumen coating. The membrane is protected on the underside with a release film backing and coated on the top surface with a fine mineral finish. A minimum selvedge of 75mm width, protected with release film, provides a quick means of completing side laps.
