Cavity Insulation FAQ's

Cavity Insulation FAQ's

What is the purpose of Cavity Insulation?

Our Cavity Insulation is a great product for reducing heat loss through a cavity wall which on application, fills the air space with material that stops heat transfer.

Cavity Insulation captures the air within the cavity, preventing heat loss and resulting in reduced heating costs.

How long does Cavity Insulation last?

Cavity  insulation is not designed to last for the entire lifespan of the building. If the Cavity Insulation is fitted correctly then it should not need to be replaced for a long period but we’d advise inspecting regularly.

Does my house have Cavity Wall Insulation?

Most houses that have been built after 1930 will have cavity walls, so you should install Cavity Wall Insulation of not already present. It is very rare for houses that were built before 1920 to have cavity walls.
