Description
Intumescent Vents for Soffit Board
Intumescent vents for soffit board to fit as new grilles, or also to replace existing plastic vents fitted to soffits. Designed to allow ventilation to loft spaces, whilst preventing external flames from entering roof space from fires in rooms below. Circular or rectangular grilles containing intumescent material that seals the vent openings in the event of a fire. Therefore protecting the roof space from flames and hot gases. Otherwise, flames could burn through plastic soffit vents and enter the roof space. Ideal for loft conversions, particularly for use over high-risk rooms such as kitchens
