Insulation
Insulation is key for a comfortable home. It keeps your house cool in summer and warm in winter. This means less energy use and lower bills. Insulation also cuts down noise and stops mould by preventing moisture. When you invest in good insulation, you save money and live better.
Adding 100mm of insulation to your home could reduce the amount of heat your home loses, meaning lower energy bills, more money in your pocket and increased value to your home. There's a range of insulation types, like PIR insulation boards, insulation rolls, and insulation slab in a variety of thicknesses. Popular brands like Celotex, EcoTherm, and Kingspan offer a range of thicknesses for different insulation applications and most brands, including the likes of JCW acoustics and Cellecta, offer acoustic insulation too.
