Built-Up Roofing (BUR) - GAFGLAS #75 Base Sheet

GAFGLAS® #75 Base Sheet


Description

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.


Uses
