Most older homes with suspended floors in the UK have large amounts of draughts coming into their homes through the floor void and inadequate floor insulation, which can cause cold feet as well as higher energy bills.

How underfloor insulation works is the current floorboards would be lifted, then insulation would be applied, and then the floorboards will then be re-laid accordingly.

The amount of heat retention will be approximately 20% using this method, and this also helps stop the draught from coming as you are essentially creating a layer between external temperatures and your floorboards, which prevents air from coming in through the floor.

With Under Floor Insulation, you would be looking at payback on your investment within five years.
