The Bilco Co.
The Lumnivent® features flat polycarbonate panels incorporated into a sloped cover design to meet UL 793 and International Building Code requirements. The sloped design encourages burning embers to roll off the covers than burn through, per the intent of fire protection standards. Compliance to both standards provides a high level of defense. The unit is designed to open automatically in the event of a fire to remove smoke, heat, and toxic gases from a burning building, improving inside air quality and visibility to allow building occupants to escape safely.
