Loft insulation is a protective layer installed within your roof space to improve energy efficiency. It can be fitted between the joists — the horizontal beams along your attic floor — or between the rafters, the angled beams that support and strengthen your roof structure.
In both cases, loft insulation reduces heat transfer between your home and the outside environment, helping maintain a comfortable indoor temperature throughout the year. Insulation installed between the joists retains heat in the rooms below, keeping the loft space cooler, while insulation fitted between the rafters helps preserve warmth within the roof space and enhances overall thermal performance.
