Firewise Supplies Ltd offer a range of fire-retardant foams, mastics, and compounds. These products all reinforce the fire resistance of walls, floors, and door frames by sealing linear gap joint seals and pipe penetrations. This helps to prevent the spread of fire and smoke through minor gaps and cracks, where conventional intumescent seals may not be fit for application. Also known as expansion sealants, the heat of a fire triggers a chemical reaction which causes the fire expanding foams, mastics, and compounds to expand up to 40 times its original size. Forming a char layer by increasing in volume but decreasing in density. All products are available to buy online with next day delivery.
