How Underfloor Insulation Works

In your home the warmth of your winter heating rises to the ceiling leaving the cold air on the floor. Coupled with the fact that your floor is in contact with the coldest air both inside and out explains why you can lose up to 15% of your heating via the floor.

If your home has a timber floor there can often be large spaces of cold air between the ground and the underside of your floor. The low insulation properties of timber together with possible leakage means that the floor creates a heat sink that takes the heat out of your house. Carpeting and underlay helps to provide some insulation, however, to maximise heat retention underfloor insulation helps creates an effective thermal barrier.
