With the Soudal Fire Board Pro firestop board, you reliably seal large service penetrations and structural openings to meet strict fire safety requirements. This double-coated stone wool board provides an effective barrier that stops the spread of flames, heat, and toxic smoke gases between fire compartments. Measuring 60x600x1200 mm, it is easy to cut to size around cables, cable trays, and pipes made of metal or plastic. Seal the perimeter and joints with a fire-rated acrylic sealant to ensure a neat, smoke-tight compartmentation.
