48" x 96" Acoustical Smoke Vent

BA-ACDSV 48” X 96” Acoustical Double-Leaf Smoke Vent 

In the event of a fire, a smoke vent can help reduce the spread of fire and ventilate smoke, giving occupants more time to escape, making it a valuable investment. Choosing the right smoke vent is more than just a precautionary measure; this is a critical and indispensable component of your building—smoke vents such as our 48” X 96” Acoustical Smoke Vent (BA-ACDSV) provide an exact solution. Not only does it offer superior ventilation, but it also prevents external sound intrusion in auditoriums, concert halls, and theaters. It also guards against low-frequency outdoor sounds like traffic and airplane noises. 

BA-ACDSV is a state-of-the-art smoke vent that enhances your utility using higher-quality building materials, mineral wool insulation, innovative construction, and a responsive, automatic mechanism minimizing potential damage to your buildings. The unit's insulation provides distinct advantages, with exceptional acoustical dampening properties that comply with building codes! 

Take a Closer Look at the BA-ACDSV 

Double-Leaf Vent Doors: BA-ACDSV utilizes a double-leaf door mechanism for an increased surface area allowing a more efficient smoke ventilation process, ideal for high-square footage buildings.  

Automated Unlatching Mechanism: Our innovative Thermolatch mechanism allows an automatic latch release that is activated using a fusible link, satisfying International Building Code (IBC 910.3.) In an emergency, the fuse will melt at temperatures about 165 degrees Fahrenheit (74 degrees Celsius,) activating the unit's responsive double-leaf doors. 

Built for Streamlined Installations: BA-ACDSV sports a frame that is easily placed and fitted into its prepared fitting for a simplified installation process. 

Soundproofed: BA-ACDSV is ideal for concert and sound halls, theatres, and loud factories due to its insulation and noise-dampening properties. This vent hatch boasts an exceptional OITC-46 and STC-50 rating.  

Durable Construction: BA-ACDSV comprises a robust 14-gauge steel construction for greater strength and durability against corrosion and the elements. 

Stylish Finish: BA-ACDSV has a standard Alkyd base red oxide primer for an elegant and highly aesthetic finish, the perfect accessory to vintage and contemporary roofs. 

We have constructed BA-ACDSV for buildings where exterior noise and safety are central considerations, including applications within auditoriums, concert halls, and theatres. With an Outdoor/Indoor Transmission Class (OITC) of -46 and a Sound Transmission Class (STC) rating of -50, BA-ACDSV offers superior sound control against outside noises while reducing the transmission of interior sound. The unit also boasts an ISO 140-18 rainfall rating, upholding well against ambient and elemental noises such as rainfall sound.  

This vent hatch is also a world-class operator in emergencies, providing safe and efficient distribution of toxic gases and smoke fumes with double-leaf doors for a larger surface area and greater ventilation in the event of an emergency. The mechanism acts as ventilation and limits the lateral spread of fires while protecting against secondary ignitions, contributing to marginal minutes that can potentially save lives. The upward ventilation will minimize the spread of flames to surrounding buildings, minimizing the harmful effects of a blaze. 

BA-ACDSV maintains the highest UL standard, with a Class A rating, ensuring peace of mind and safe integration with your building materials. With rigid 4" wool insulation, tested to satisfy UL790 and UL793 requirements, you can install this vent door with complete peace of mind; whether you require a one or two-hour rating, BA-ACDSV has you covered. 

Our BA-ACDSV's uncompromising, tough, and rugged 14-gauge steel will withstand heat. BA-ACDSV is on the cutting edge of design, incorporating a Thermolatch mechanism that will activate by melting at temperatures above 165 degrees Fahrenheit (74 degrees Celsius.) The powerful opening mechanism of this unit will activate even with loads as heavy as 438 kilograms per square meter (90 pounds per square foot) in the form of snow cover and wind forces. This unit is also weatherproofed with complete insulation and gaskets, reducing the potential internal corrosion to its structural integrity. Invest in the BA-ACDSV Acoustical Roof Vent for a reliable and effective solution to your smoke ventilation and noise reduction needs.
