Siderise CW-FS120 Firestop for Curtain Walls is now being installed at 989 6th Avenue—delivering robust passive fire protection for this dynamic new 73-story development in the heart of Manhattan.
The intricate unitized curtain wall façade was designed, engineered, and fabricated by Bisam Façade, and installed by Marvel Contracting.
Siderise CW-FS120 Firestop was specified to provide floor-to-floor compartmentation, protecting the void space at the perimeter joint between the edge of the floor slab and the internal surface of the external wall assembly. It offers a third-party certified FT rating of up to three hours (resistance to fire spread and temperature rise on the non-fire side) when tested to ASTM E2307 as part of the CW Perimeter Barrier System.
