Wall insulation is not easy to check or install, but it makes a big difference to the comfort and warmth of your home.

Once you’ve insulated your ceiling and underfloor, installing wall insulation is the next most effective step for reducing heat loss in your home. It’s difficult to check and install wall insulation in existing houses without taking the lining or cladding off, so take the opportunity to do it if you’re renovating.

Blanket or mat (segmented) insulation is available in glasswool (fibreglass), wool, polyester, wool/polyester mix, and mineral wool.
