      Why GAFGLAS® #80 Ultima™ Base Sheet?

      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

      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
