The benefits of floor insulation can be significant. 10-20% of heat loss from a building can be through the floors if they’re not insulated to a reasonable standard. According to the Energy Saving Trust you could save between £40-£65 on your energy bill through floor insulation. When you stack that against other savings you can make on insulating the rest of your house plus the length of time you’ll live in your home, the savings can add up.
Reduced heat loss/waste
Heat rises, so insulating your house properly means you keep more heat inside the house. Have a check around the house and see where you can feel any draughts. You can then look to eliminate them with floor insulation. Whilst doing this it’s also worth considering loft insulation so you can get rid of any draughts through the ceilings, for example from loft hatches leaking hot air into the cold roof space. The combination of cold air through the floors and hot air out of gaps in a loft hatch can lose heat very quickly. And what you lose through the floors you’ll pay for in your bill.
By correctly insulating suspended timber floors you can save money (and for some this could mean avoiding or alleviating fuel poverty). As you keep more heat inside your home with floor (and roof) insulation you’ll reduce the amount of energy you use (and therefore your bill) whilst keeping your house snug.
It’s low to no maintenance
Floor insulation is maintenance-free once installed.
It future proofs your home
Unlike newer buildings, many older houses were not fitted with floor insulation when they were first built, so by investing in floor insulation you can bring your house up to date and improve your EPC ratings.
