Mastic Intumescent Strips

Our fire-rated intumescent strips are here to help keep businesses and homes as fire-safe as possible, using a self-adhesive backing to offer quick solutions and installations to all of our buyers. We offer a wide range of intumescent strips, all of which are available in fire and smoke options - or plain fire options. We offer all of these in a range of lengths and thicknesses, so no matter your buying needs, Builder Depot has you covered.
