GlasGrid® CG50


 

GlasGrid CG products are high strength, high modulus fiberglass meshes that reduce the potential for thermal and stress-related cracks through to the surface of a new asphalt overlay.

From the regular GlasGrid products there is one significant enhancement: the non-woven fabric layer is saturated with bitumen in order to provide an effective moisture barrier.

GlasGrid CG 50 provides a grid tensile strength of 50 kN/m (280 lbs./in.) across the width and length.
