Uninsulated properties generally lose 45% of the heat generated by their central heating system. Most of the heat loss happens in the loft of your home because of the fact that warm air rises. This means that keeping your loft insulated is essential to keeping your home warm and your energy bills low.
Loft insulation is the process of laying down insulation material between the joists of your loft. This prevents heat from escaping during winter, as well as preventing it from penetrating your living spaces in the summer.
Due to the relative simplicity of the process, loft insulation is one of the cheaper insulation methods out in the market. Add a 40 year lifespan into the mix, and you have an effective insulation method that essentially pays for itself several times over, thanks to lowered energy bills.
