In applications where the potential cost of damage from leaks is severe, #80 Ultima Base Sheets offer ultimate leak protection and serve as an effective flame retarder in torch-applied modified bitumen systems. Designed to meet UL Class A ratings, they roll out flat for easy installation and system guarantees are available for up to 20 years.
Benefits of GAFGLAS® #80 Ultima™ Base Sheet include:
Helps prevent splitting and leakage: closed-pore design means asphalt doesn’t bleed through, so system remains independent of deck movement when mechanically attached
Rolls out flat for easy installation
Resists long-term curling and shrinkage that can cause premature roof failure (as can happen with organic products)
Inorganic Micro Weave Core helps prevent decay and provides superior tensile strength with dimensional stability
