Specialist Insulation Supplies offer a wide range of fire rated insulation products for both pipes & ducts.

SIS stock and supply Isover U Protect slabs that provide a lightweight solution to providing fire protection to ducts, it is a product that due to its weight (up to 73% lighter than traditional stone wall products) & that it only requires adhesive at penetrations through a wall can offer a very competitive alternative to traditional fire rated duct insulation products. Using this innovative product on ventilation & smoke ductwork you can achieve up to 120 minute’s fire resistance, and this can be achieved using the U Protect product that has a distinctive black aluminium foil facing. Isover have updated and rebranded the product and as a result the product is now supplied with a black foil facing which allows for easy on-site identification.
