Cavity Wall Insulation

Blown mineral fibre is a fast and cost effective way to significantly reduce the amount of energy needed to heat a home. This process can reduce heating costs by an average of 15%.

The Savings

Around a third of all heat lost in an un-insulated home is lost through the walls. If you have cavity walls, insulating them will make a great difference and could save you around £115 per year on fuel bills (Energy Saving Trust).
