Around 25% of all the heat in your home gets lost through your roof. This is like wrapping your home in wool and can keep warm air retained within so that you require less energy to heat the home. In this way, you can have a more comfortable property and spend less money on energy expenses. As per the Department for Energy and Climate Change, only 16.2 million out of the 28.4 million properties in Great Britain have loft insulation. Thus, 34% of property owners with a loft can save a lot of money with insulated lofts.
