GAFGLAS® #75 Base Sheet is a premium roofing base sheet constructed with a strong glass mat that is coated on both sides to assure a closed-sheet design to prevent asphalt bleed-through. The sealed sheet also serves as an effective flame retarder for the application of torch-applied modified bitumen membranes.
GAFGLAS® #75 Base Sheet is engineered for use in the construction of GAFGLAS® built-up and RUBEROID® modified bitumen roofs. It is suitable for nailable specifications, such as plywood, where bleed-through is a concern.
