Expol underfloor insulation
Expol Underfloor Insulation is a cost effective and energy efficient way to make your home more comfortable all year round. The polystyrene Expol insulation panels are placed snugly between your floor joists. Enjoy warmer feet and save around 12% on your heating bill*.
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 is a large space of cold air between the ground and the underside of your floor. The low insulation properties of timber, together with possible leakage, mean that the floor creates a heat sink, taking heat out of your house. Carpeting and underlay help provide some insulation, however, to maximise heat retention, Expol Underfloor Insulation creates an effective thermal barrier.

Insulation - Tips and Facts
- Insulating floors and ceilings makes a home cosy and welcoming.
- By saving energy in the home, you are not only helping yourself, you are also helping the planet.
- If a house already has a thin and ineffective insulation, it is worthwhile adding an extra layer on top.
- The money you spend now in insulation will soon pay for itself in reduced energy bills and additional comfort in the future.
- Insulation performance is measured by R-value, the higher the R-value the more effective it is.
- Even if the air temperature is cold, a person standing on a warm floor will feel more comfortable. Damp houses are unhealthy to live in, insulating under your floor will help make your home dryer. If you have a serious dampness problem in your home, correct this prior to insulating your floor.
- If you have cold and draughty floors, you will waste power heating your home.
