Underfloor insulation is a brilliant approach to maintaining warmth as well as preventing up to 310kg of carbon dioxide from being released annually as a direct result of energy-use in your home. Sealing the gaps between flooring and skirting will further endorse insulation, preventing draughts and saving you energy costs. Underfloor insulation should be installed beneath the ground level only, as well as any other floors that sit above an unheated space.
Suspended floor insulation
Suspended floors are built over horizontal joists, allowing for a gap between the floorboards and the ground. Installing insulation beneath a suspended floor is a simple upgrade with great long-term benefits, allowing your property to better retain heat for years to come. In these instances, mineral wool is fitted between the joists underneath your floorboards and is supported by netting.
Solid floor insulation
Unlike suspended floors, solid floors exist as a solid concrete or flagstone surface without underfloor ventilation.
There are two ways in which a solid floor can be insulated. The first involves adding two layers of insulating board over the existing floor, allowing for more protection. The second approach involves the removal of the existing solid floor to install a damp-proof membrane, a new insulating layer and an updated solid floor material in its place. This is more costly than the first method and is therefore most often completed alongside another area of home refurbishment.
