Nystrom Acoustical Series smoke vents are a rooftop venting system that automatically opens - releasing heat, smoke, and noxious fumes during a fire. Each smoke vent will open automatically when a fusible link inside the vent reaches its melting temperature. Smoke vents are spring-operated to open against a 10 psf snow load.

SVX Acoustical smoke vents feature:

• Innovative, upward opening, single-layer door construction.
• Energy-efficient R13 insulation for optimal envelope performance.
• Acoustical ratings to STC 45 & OITC 37.
• UL793 Listed and FM 4430 Approved

Nystrom recently developed a new order guide and corresponding model numbering system to help you select and specify product options that meet your specific needs. We are currently updating all of our downloadable information with the new nomenclature but the process is not yet complete. We apologize for any inconvenience this may cause. Please do not hesitate to contact us with any questions or concerns.
