DynaWeld Cap 180 FR is used as a polyester-reinforced mineralsurfaced cap or flashing sheet in a variety of multi-ply roofing systems.
Ceramic-Coated Roofing Granules: Specifically engineered for optimal embedment in the SBS-blend sheet. The ceramic coating promotes excellent long-term adhesion.
High-Quality SBS Rubber and Asphalt Blend: Lends elasticity and flexibility to the sheet. The elongation and recovery properties allow the product to easily accommodate the continual expansion and contraction experienced on all roofs. The FR blend contains additional fire-retardant additives.
Polyester Reinforcement Mat: Polyester mat with bidirectional glass-scrim reinforcement offers robust tear strength and puncture resistance, allowing for high wind performance and an excellent hail rating. The sheet also exhibits strong dimensional stability and enhanced elongation.
Polyolefin Burn-Off Film: Promotes ease of heat welding.
Colors: White, Black and Tan (Black and Tan may require extended lead times.)
