ROTATEX™ G550 G35A comprises a glass laid scrim on a 35 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. Owing to its low basis weight, this glass web is easily impregnated by all types of bitumen, even those with a high additive content, and on rapid impregnation lines.
The glass web improves the fire resistance of the bituminous membrane by reducing dripping during the BRoof test.
This complex offers a good balance between performance and cost.
