Floor insulation

Floor insulationUnder floor insulation is another good way of preventing heat loss through the floor. This method is especially appropriate for older houses. Many older properties have ‘suspended floors’, where there is a gap underneath the floorboards. This gap can be filled by temporarily removing the floorboards and laying rolls of mineral wool insulation.

If you choose to install this type of insulation yourself, it is important to ensure that you do not block ventilation points, as floorboards will rot without adequate ventilation.

Another highly inexpensive way of preventing heat loss via the floor is to fill the gaps between the floor and skirting boards using caulking or a sealant. It is also possible to place a layer of insulation, such as a polyfoam board, below your carpet in order to further improve energy efficiency.
