The ROTATEX™ G900 AL70A complex comprises a glass laid scrim affixed to a 70 gsm hammered aluminum film.
The glass laid scrim provides very high mechanical strength and ensures ease of use of the complex by avoiding breakage of the aluminum film on bituminous impregnation lines.
The bonding agent developed for this complex prevents delamination during use of the reinforcement, even on high-speed lines.
The surface appearance of the aluminum allows for good adhesion of the bitumen and thus good cohesion of the membrane.
ROTATEX™ G900 AL70A offers a good balance between rigidity and ease of use on production lines.
