Loft insulation is a simple and effective way to improve the energy efficiency of your home and lower your bills. Materials used for loft insulation are typically glass fibre or renewable wood fibre, which when installed into your loft space, prevent heat from escaping.
Loft insulation can be installed between the joists of your loft floor or in between the rafters that support the roof.
If you have easy access to your loft then take a look at the current floor space of your loft, between the rafters or joists. If there is a thick layer of insulation between 270mm and 300mm in situ it may be that loft insulation has already been installed.
