SCD - Smoke and heat vent
SCD smoke and heat vents are used in public buildings, warehouses, production facilities, etc. They are designed for installation on flat roofs with a slope up to 15°.
SCD vents’ main function is extraction of smoke and hot toxic gases occurring during fire in under-ceiling space. SCD vents openable flaps are filled with translucent materials. Therefore the vents are roof skylights in the same time. Another SCD function is a periodic room ventilation, which requires use of additional gear.
The priority function of SCD vents is in each case the smoke exhaust function. The use of SCD vents allows, among other things, to lower the fire resistance class of the building, enlarge the permissible fire zones, extend escape routes.
