Bilco’s Single-Leaf Smoke Vents Receive UL Approval
NEW HAVEN, Conn. — The Bilco Company’s Type SV Single Leaf Automatic Smoke Vents, available with a metal or domed polycarbonate cover for natural daylighting, have received UL approval per the UL 793 standard for Automatically Operated Roof Vents for Smoke and Heat.
UL is a global, independent safety science company that is dedicated to promoting safe living and working environments by safeguarding people, products and places. The UL 793 fire protection standard for automatic smoke vents designates several different tests to ensure safety for these products. To receive certification, vents are tested to ensure that they fully open against a simulated 10 PSF snow and wind load, remain open and latched under these conditions, and remain closed when subjected to wind uplift pressures. While Bilco’s single leaf smoke vents have always been designed to these performance standards, the products have now been officially tested to carry the UL label.
