A traditional cottage or a detached house loses nearly 6% of its heat through the floor.
There are a number of things that can be done to improve this situation.
Ground floor insulation can be installed against a ventilated space under the floorboards.
LBC is required to lift historic floorboards and alter the floor height.
In some cases, sealing gaps and draught stripping skirting boards may be the only solution possible, together with laying a carpet with an insulating underlay. It is important to use moisture permeable materials to prevent timber decay.
Generally it is more difficult and expensive to retrofit insulation to solid floors, especially if existing finishes and floor height must be retained.
