Details
FyreFlange Firestop Angles consist of galvanized steel retaining angles with a layer of bonded intumescent material designed to be installed around the perimeter of non-dampered square or rectangular steel ducts. Powder coated red for easy inspection and identification; FyreFlange Firestop Angles meet the exacting criteria of ASTM E814 (UL1479) and CAN/ULC S115.
Unlike traditional duct firestopping methods utilizing backer or packing materials, sealants, and angles installed and inspected in stages, FyreFlange Firestop Angle can be installed as the duct is installed and inspected just once after the installation is complete. FyreFlange is available as a pre-firestopped angle or as intumescent gasketing for field fabrication with 2 in (51 mm) by 2 in (51 mm) min 20 GA (or heavier) steel angles.
- Single stage installation
- Economical—saves labor
- No additional firestop or backing material required
