AUTOTAK GG Broof(t3)
sbs pol - 20 °C



AUTOTAK GG is a self-adhering waterproofing membrane made of distilled bitumen modified with SBS (Styrene-Butadiene-Styrene) polymers, with an adhesive coating on the lower face.

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 and from the selvedge strips, AUTOTAK GG will adhere in place without the need of a propane gas torch or a hot air machine.



The carrier is an high-grade woven glass that combines good tensile strength with excellent dimensional stability. Thanks to this special reinforcement, AUTOTAK GG has specific resistance proprieties to external fire.
