Underfloor Insulation

Underfloor insulation involves adding insulating material beneath suspended timber floors—a common feature in many older UK homes, particularly those built before the 1970s. These floors often have gaps that allow cold air to enter and warm air to escape, leading to draughts and higher energy bills.

By insulating the space between the floor joists, you create a thermal barrier that keeps the warmth in and the cold out. This is especially beneficial for homes in Waltham Forest, where improving energy efficiency can make a noticeable difference to both comfort and heating costs.

At Kanopiworks, we specialize in retrofit underfloor insulation that enhances comfort, lowers bills, and supports a more energy-efficient home—without major disruption to your daily life.

Benefits of Underfloor Insulation

  • Warmer floors – Say goodbye to cold feet and draughty rooms.

  • Energy savings – Cut down on heating costs by reducing heat loss through suspended floors.

  • Less noise – Acts as a sound barrier between floors, adding peace and quiet.

  • Moisture control – Helps prevent dampness and condensation under your floorboards.

  • Adds value – Improves overall energy performance and appeals to future buyers.

The process for underfloor insulation is the same as our trusted loft insulation method, ensuring quality, efficiency, and minimal disruption.


All materials are BBA-certified and compliant with UK building regulations.
