Intumescent Sealants

Intumescent sealants reinforce the fire resistance of walls, floors and door frames by sealing linear gap joint seals and metallic pipe penetrations. Acrylic intumescent seals expand to fill a cavity when subjected to extreme heat and provide an extra layer of fire-resistant material to protect the structural integrity of a building. 

Our range of fire resistant sealants resist both fire and smoke for up to four hours and meet the most important European Standards for the fire classification of construction products. We stock the leading intumescent sealant brands, including Lorient, Corofil and Pyroplex. For precise and consistent application, you can use a long-lasting foam applicator gun, which offers an adjustable flow rate and increased speed when using the foam.
