Underfloor Insulation for Timber Floors

Heat naturally moves from places of high thermal energy (hot air) to areas of low thermal energy (cool air). In your home, heat continues to move around the inside until the temperature is consistent in all areas of the house.

Without proven insulation solutions such as Expol, this can become an issue in winter when the warm air escapes and leaves your home uncomfortably cold, and in summer when unwanted hot air can sit inside your home.

Retrofitting underfloor insulation for your timber floorboards will help you manage the natural flow of heat throughout your home to achieve a comfortable temperature all year round.

Expol is ideal for retrofitting underfloor insulation in homes with existing timber floors to improve and modernise its insulation properties. The retrofit floor insulation process is quick and straightforward, and each pack comes with a complete set of detailed instructions. Watch our installation video for installing underfloor insulation tips.

Expol can also be used for new builds or homes undergoing renovations, extensions, or knock-down rebuilds where new timber floors are being laid. By adding insulation underfloor, you can significantly enhance the energy efficiency of your new home and ensure greater comfort.

Insulating timber floorboards offers significant advantages, enhancing both comfort and efficiency in your home. Here’s why it’s worth doing:

1. Year-round comfort: Insulation creates consistent indoor temperatures for an always comfortable living environment, regardless of the weather outside.
2. Lower energy bills: By minimising heat loss from below, floor insulation reduces the need for constant heating and cooling, meaning lower energy costs.
3. Reduced drafts: Cold air can rise through gaps and cracks in uninsulated floors, creating uncomfortable drafts. Insulating under the floor helps seal these gaps.
4. Improved air quality: Underfloor insulation helps keep out moisture and dust. This helps maintain clean air inside the home, which is great for allergy sufferers.
5. Enhanced soundproofing: Underfloor insulation foam helps reduce noise. It absorbs sounds, making your home quieter and more peaceful.
6. Increased property value: Energy-efficient homes are more attractive to potential buyers. Under timber floor insulation can increase your property’s value.
7. Sustainability: By reducing the amount of energy needed to heat or cool your home, you lower your carbon footprint, making your home more eco-friendly.
