Loft insulation is effective for at least 40 years. The National Insulation Association found that cavity wall and loft insulation could be exceptionally cost effective, with the initial cost of insulation being repaid within just three years. Choose from rolls of mineral wool insulation, rigid insulation board or thermal insulation rolls depending on your needs.
