How to install floor insulation
Insulating your floors will not only keep you warmer, it'll help you keep your heating bills down. An un-insulated concrete sub floor can absorb up to 30% of your home's heating.
The method of insulating your floors will depend on what type of floor your have:
If you're having new wooden flooring installed, put a layer of mineral wool insulation under the floorboards first.
If you're having new carpets fitted, consider installing an additional insulating underlay beneath them.
Vinyl floors are good insulators, but can be improved by adding another insulating layer underneath the vinyl. Ensure the vinyl is free from tears and cracks, especially around the edges as this can reduce its insulating properties.
Because of their rigid nature and the fact that they're often laid on a concrete base (which absorbs heat) it is very difficult to insulate a tiled floor. However, placing a rug over the tiles can help keep in the warmth during the chillier winter months. Just remember to invest in some anti-slip rug tape to keep them in place and avoid slips.
