Under floor insulation with lagged pipes and netting to keep insulation in

Under Floor Insulation

Underfloor insulation can be installed in houses that have suspended floors or a cavity underneath. Older homes (pre-1970s) are most likely to have suspended timber floors.  If you have air bricks or ventilation bricks on the outside wall(s) of your house that is below floor level, you probably have a suspended timber floor.

Our surveyors would be able to check suitability at the survey.

Floor insulation can also be installed on solid floors such as concrete but this is a much bigger job and you will need to build on top of the existing floor.

How is the insulation installed?

Timber floors can be insulated by entering the crawl space via an existing hatch or creating a new one and laying mineral wool insulation supported by netting between the floor joists.

You should consider insulating any floors that are above unheated spaces.

How long does it take to install?

Depending on the size of your property, on average our installers would complete the installation within one day.
