The ROTAFLEX NEO PES35/G1100P/PES35 complex comprises a glass laid scrim inserted between two non-woven PET layers.
The G1100P laid scrim offers extremely high tensile strength in the longitudinal direction, and this is even greater in the transverse direction. It is designed to limit the “flared end” effect on the membrane.
The specific ROTAFLEX™ NEO hydrobonding process, combined with the use of a special adhesive, provides extremely high mechanical strength, resistance to static and dynamic puncture, and tear strength. The glass laid scrim stabilizes the composite and ensures excellent dimensional stability, even after coating in bitumen.
The glass laid scrim also contributes to the product’s fire resistance.
The production technique serves to obtain a reinforcement with an excellent visual appearance and high permeability, ensuring quick and complete bitumen impregnation.
This specialist product is the ideal reinforcement to ensure mechanical performance in top-of-the-range membranes.
The visual appearance of the surface can be modified to suit products to receive multiple coatings and/or different coatings on either side.
