Tri-Ply #75 Base Sheet is a premium roofing base sheet constructed with a fiberglass mat reinforcing that is coated on both sides to ensure 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. Tri-Ply #75 base sheet is engineered for use in the construction of Tri-Ply built-up and modified bitumen roofs.
