Base and Ply Sheets

StressBase 80 Plus

  • Advanced Rubber Technology
  • Security in Multi-Ply Construction

StressBase 80 Plus is a high-strength puncture and fatigue-resistant, modified roofing membrane that consists of fiberglass reinforcement sandwiched by Styrene-Butadiene-Styrene (SBS) rubber in a high penetration index asphalt mixture. StressBase 80 Plus sheets can be used as a nailable base sheet over approved substrates, as a base flashing for hot- and cold-applied roof systems, or as an interply in Garland's hot or cold-applied systems. StressBase 80 Plus is typically used in two (2) or three (3) ply modified systems and also can be used in three (3) or four (4) ply BUR's.

Security in Multi-Ply Construction

StressBase 80 Plus sheets are the base component of a multi-ply roof system. They combine the inherent advantages and proven performance of multi-ply protection with the strength, flexibility, and elongation of elastomeric systems. This unique combination minimizes dependence on perfect workmanship, contact adhesive seaming, etc.

Advanced Rubber Technology

The modifier utilized is SBS (Styrene-Butadiene-Styrene). When the SBS rubber is properly dispersed throughout the high-penetration asphalt, the rubber provides increased thermal shock resistance, UV protection, heat resistance, elongation, and low-temperature flexibility. A special high-shear mixer is used in manufacturing to ensure proper dispersion.
