Floor insulation

What is it?

Insulation can be applied to the ground floor of your home or on any floors that are over an unheated space such as a garage.

For older homes with suspended timber floors, the floorboards will need to be lifted up and the insulation will be installed beneath them. Alternatively, spray foam insulation can be applied directly under the floorboards using a remote controlled robot which will avoid needing to take up the floor boards.

Newer homes with concrete floors can have insulation laid over the top, this can be easily done if the floor is being replaced.
