      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
