Why insulate your walls?
Wall insulation is one of the most important factors when insulating your home, particularly since an estimated 30-40% of the heat in your home is lost through the walls.
Without wall insulation, air can easily escape through the walls of your home. This means any effort you put into heating or cooling your home can be quickly lost, making it difficult and expensive to maintain a comfortable inside temperature.

Absolute Energy is an authorised CosyWall Insulation installer. CosyWall Insulation is a wall insulation system designed to insulate the walls of older homes. It provides thermal and acoustical insulation to existing wall cavities and is installed without the cost and hassle of removing the internal linings.
Installation is done via small holes through the external cladding, or from inside via holes in the internal linings. The result is high installed R-values and a warm cosy home.
