sbs alu - 35 °C




AUTOTAK ALU is a special self-adhering vapour barrier consisting of a reinforced composite glass-aluminium foil coated on the lower face with an adhesive SBS-modified bituminous compound.

Application is very simple and safe: once aligned the roll in place over a clean and primed substrate, by simply removing the silicone films from the underside, AUTOTAK ALU will adhere in place without the need of a propane gas torch or a hot air machine.



The carrier is a special glass grid coupled to an aluminium foil that makes AUTOTAK ALU ideally suited for applications where a perfect vapour barrier is required.



Intended use according CE Mark Standards
