            Ensure fire doors are fitted to standard with our intumescent mastic, which is an effective fire-retardant sealant.

            Keep your home and family safe with our intumescent mastic, which helps prevent fire and smoke spreading through a building. The intumescent substance swells when exposed to heat. This seals the gaps within walls, floors and ceilings, giving peace of mind that your home is protected.
