Underfloor Insulation

Floor insulation is a simple and effective way to keep your home warm and reduce your energy bills.

Many homes, especially newer ones, will have a ground floor made of solid concrete. This can be insulated when it needs to be replaced, or can have rigid insulation laid on top.

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.

Underfloor Insulation

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

Solid floors are insulated using rigid insulation foam, which can be fitted either above or below the concrete. If the concrete is above the insulation it can sometimes store heat during the day, which helps keep the room warm at night. If the insulation is above the concrete the room will heat up more quickly in the morning.

Benefits of Underfloor Insulation :-


  • Reduces heat loss and saves energy;

  • Reduces unwanted draughts;

  • Increases floor temperature by around 3 degrees;

  • Improves your home's energy efficiency rating (EPC Rating).
