Underfloor Insulation

Suspended underfloor insulation refers to the process of insulating the space between the floor and the ground in a building. It is a method used to improve energy efficiency, reduce heat loss, and enhance thermal comfort.


By installing insulation material in this area, it helps to prevent cold air from entering the building and warm air from escaping, resulting in a more comfortable indoor environment and energy savings.

How does suspended underfloor insulation work?

Older homes 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 are below floor level, you probably have a suspended timber floor.

If you have a basement or cellar beneath your house that you can get into safely, take a look down there to see what type of floor you have. If the floor is a suspended wooden floor, you will probably be able to see wooden joists and the undersides of the floorboards.

If you don’t have access to the space underneath your house, you will need to lift a corner of the carpet and underlay to have a look.

Timber floors can be insulated by lifting the floorboards and laying mineral wool insulation supported by netting between the joists.
