66" x 144" Acoustical Smoke Vent - Bilco

Commercial and industrial buildings need smoke vents to eliminate smoke within a building during a fire. Note that inhaling the toxic fumes generated from the fire can cause a person to suffocate and cause other severe health complications. One type of smoke vent you can get is the 66" x 144" Acoustical Smoke Vent - Bilco. It comes with a multi-wall polycarbonate cover design that resists UV degradation and offers superior insulation performance over traditional domes.

Other features of the smoke vent include:

• Material: Cover is 14 gauge (2 mm) G-90 paint bond galvanized steel.

• Covers: Brakeformed, hollow-metal design with 4" (100 mm) mineral wool insulation, 5-3/4" (146 mm) beaded, overlapping flange, fully welded at corners, and internally reinforced for 40 psf (195 kg/m2) live load.

• Curb: 12" (305mm) in height with integral capflashing, 4" (100 mm) fiberboard insulation, fully welded at corners, and 6-7/8" (175mm) mounting flange with 7/16" holes (11mm) provided for securing frame to the roof deck.

• Gasket: Extruded PVC gaskets permanently adhered to the underside of the cover and the top of the curb.

• Hinges: Heavy-duty pintle hinges with 3/8" (9 mm) type 316 stainless steel hinge pins.

• Latch: Positive hold/release mechanism controlled by a single UL-listed 165°F (74°C) fusible link with a separate latching point for each cover. Designed to hold the covers closed against a 90 psf (438kg/m2) wind uplift force. Provided with interior and exterior pull release cables to manually open vent covers.

• Operation: When the acoustical smoke vent is released, high performance gas springs open covers against a 10 psf (49kg/m2) snow/wind load and lock covers in the open position. Gas springs have integral dampers to assure a controlled rate of cover opening and have a cyclic durability of 50,000 cycles.

• Performance Ratings: STC-50, OITC 46, and ISO 140-18 (rainfall - 37.5 db) sound ratings. UL-listed.

• Comply with UL 793 and UL 790 Class A (burning brand test).

• Finish: Alkyd base red oxide primer. 

• Hardware: Corrosion-resistant gas springs and hot dip galvanized steel stop cables. All other hardware is zinc plated/chromate sealed.
