About

Whether you use your basement primarily for storage or as a recreational space, insulating this section of your home with XPS / rigid mineral wool or EPS Insulation can yield significant financial benefits. According to the U.K. Department of Energy, insulating your basement walls can save up to £350 annually in some regions. This is especially true in “tight” homes with a strong seal around upstairs windows and doors, where a large portion of heat loss comes from an uninsulated basement.
