Are you looking to provide safe, efficient, and reliable ventilation to your buildings but have limited options due to noise and building code requirements? Your search stops at BA-BSVZG-Q 48" x 72" Quad Door AcousticMAX Smoke Vent – STC 50 OITC 47!   

This state-of-the-art solution, optimized by Best Access Doors, provides effective sound attenuation and noise control while also boasting top-of-the-line automatic ventilation properties. With a melting fusible link, this double-leaf smoke vent springs into action, unlatching for immediate ventilation while providing a point of attack for firefighters. 

Why Choose BA-BSVZG-Q? 

Superior Acoustical Dampening: With an STC rating of 50 and OITC of 47, BA-BSVZG-Q offers substantial sound isolation, significantly reducing the sound of loud music, aircraft and mechanical noise with the use of sound mats in its cover and curb.    

Automated Ventilation: BA-BSVZG-Q features a positive releasing latch, activated by a rigorously tested UL-listed fusible link, which melts at temperatures over 165°F. Once the fuse melts, you can count on BA-BSVZG-Q's covers to release, expelling flames, fumes, and toxic gases.      

Note: Alternate fusible link temperatures are available; see below.    

Weatherproofed Construction: BA-BSVZG-Q has EPDM rubber gaskets permanently adhered to its cover, providing a tight seal while leaving the elements out of your spaces. BA-BSVZG-Q has mineral wool insulation within its cover for enhanced thermal resistance (R-14) and reduced energy consumption.     

Note: 2" Polyisocyanurate (PIR) insulation (R-12) is available as an alternative; please contact our staff to request.     

Increased Ventilation Capacity: BA-BSVZG-Q utilizes its entire double-leaf design for venting, with four segments, providing reduced pressure buildup, uniform smoke distribution, and a point of attack for fire-fighters.   

EZ Tab for Easy Mounting: BA-BSVZG-Q is a single-wall curb hatch with a mounting flange with EZ tabs that make installations quicker and hassle-free.     

Note: Double wall, curb mount, and double wall with no counterflashing alternatives are available; please contact our staff to request.
