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.

GAFGLAS built-up and RUBEROID® modified bitumen roofs. It is suitable
for nailable specifications, such as plywood, where bleed-through is a
concern.
Advantages
• Extra strength for excellent nail-holding ability. Superb tensile
strength and resilience and no bleed through, thereby reducing risks of
splitting and cracking of membrane.

membrane performance.
