Automatic Smoke Vents

The Type SV Single Leaf Automatic Smoke Vents from Bilco have received UL approval per the UL 793 standard for automatically operated roof vents for smoke and heat. The vents are available with a metal cover or a domed polycarbonate cover for natural daylighting. The device is designed to open automatically in the event of a fire to remove smoke, heat and toxic gases from a burning building, which improves inside air quality and visibility.
