The ROTATEX™ G915 G50A complex comprises a glass laid scrim affixed to a 50 gsm glass web. The modified SBR adhesive is temperature-stable and compatible with bitumen. This complex can be used on rapid and high-performance impregnation lines, owing to the tensile strength and dimensional stability provided by the glass laid scrim.
The glass web helps to ensure the dimensional stability of the complex and the bituminous membrane. With its greater basis weight and good permeability, this glass web is easily impregnated by all types of bitumen, even those with a high additive content, and on rapid impregnation lines. It allows for control of membrane thickness, even for thick membranes. The glass web improves the fire resistance of the bituminous membrane by reducing dripping during the BRoof test.
This complex has been optimized to obtain bituminous membranes with tensile strengths greater than 1000 N/5 cm.
