Loft insulation is a protective layer installed within your roof space to enhance 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, helping to maintain consistent indoor temperatures and reduce energy costs.
In both cases, loft insulation minimizes heat transfer between your home and the outside environment, helping maintain a comfortable indoor temperature year-round. Insulation installed between the joists retains heat in the rooms below, keeping the loft space cooler, while insulation fitted between the rafters preserves warmth within the roof space, enhancing overall thermal efficiency and comfort.
