Expanding Foam

Keep insulation airtight with our range of expanding foam. An ideal addition for your collection of building materials for construction and home improvement, spray foam insulation provides an excellent level of insulation and is easier to administer than traditional insulation methods. Toolstation stocks the highest quality expanding foam with brands such as Dow, Everbuild and Siroflex available for the best foam insulation possible.

To fix plasterboard, insulation board and common building substrates, try Insta Stick Multi Purpose B2 fire rated expanding foam or Siroflex Dry Wall expanding foam fix. For high performance polyurethane foam, try the Dow fire rated expanding foam. Alternatively, check out Siroflex expanding foam for general construction and home improvement or Everbuild Exact Gap expanding foam for precision application.

For trade and building purposes, use a foam gun for faster and easier application by choosing our Trade Applicator foam gun or Professional foam gun with a solid metal body and plastic clad metal handle. To remove expanding foam easily, view our range of expanding foam remover such as the Everbuild Foam Eater or the Everbuild expanding foam cleaner, perfect for removing and cleaning Polyurethane foam from foam guns.
