StormSafe™ Anchor Sheet for self-adhered membranes is a tough, non-breathable synthetic anchor sheet designed and manufactured to meet industry and code requirements for self-adhered low slope roofing applications.
It is a polypropylene woven fabric coated on both sides with polypropylene. StormSafe™ Anchor Sheet is designed for use as an anchor sheet for Liberty™ (Modified Bitumen) and Freedom™ TPO self-adhered roof systems.
StormSafe™ Anchor Sheet’s woven fabric creates a tough, durable reinforcement and its polypropylene coating makes it suitable for many applications. StormSafe™ Anchor Sheet is alkaline resistant, making it suitable for use over lightweight insulating concrete systems. The tough woven fabric makes it extremely tear resistant. In addition, the polypropylene coating ensures a good bond with both the butyl adhesive of Freedom™ membranes and the SBS modified adhesive of Liberty™ SA Base/Ply and Liberty™ Cap membranes.
StormSafe™ Anchor Sheet should be applied with the beige color on top (weather side) and white color coating towards the deck side. Suitable substrates include: plywood, OSB, acceptable EnergyGuard™ Insulations, and lightweight insulating concrete. The product is designed to be installed mechanically over approved roofing substrates using acceptable fasteners that include galvanized nails with 1-inch integral heads or Drill-Tec™ fasteners and plates in accordance with applicable specifications. Prior to installing any self-adhering membrane, StormSafe™ Anchor Sheet must be clean and dry. Use care walking on the sheet when it is wet as it may be slippery.
