Availability

Code compliant perimeter fire containtment systems require FireSpan® 90 at a minimum of 2 or greater and/or FireSpan® 40 at 4 or greater and will have a UL® certification. However, each UL® or Intertek® listing requires a specific thickness. Refer to the design listing for correct thickness. Lesser thicknesses, respectively, should be used for thermal or acoustical applications and will not have a certification.

Installation

FireSpan® products should be mechanically attached to horizontal and vertical mullions based on mechanical fastener requirements per UL/Intertek tested and listed system. Reinforce FireSpan® insulation on the outer insulation surface at the safing line. Typical reinforcement members include hat channels, L angles, and T bars. Thermafiber Inc.s patented Impasse® system is designed to quickly and easily mechanically attach FireSpan® insulation to curtain wall systems.
