Do I need loft insulation?
Loft or roof insulation acts as a barrier of material within your roof space. Insulation of this type can be laid between the rafters of the roof or laid between the joists. Having roof and loft insulation will slow down the transfer of heat between your living space and the outside.
Having loft or roof insulation will create a warmer home in the winter and a cooler home during the summer. By having insulation installed between the joints of the floor this will allow your living spaces to harness the warmth.
