Insulation is a product that can reduce heat loss or heat gain by providing a barrier between areas that are different in temperature.
Home insulation reduces the amount of heat that escapes from a building in the winter and helps to keep it cooler in the summer. It helps to make your home more energy efficient.
Cavity wall insulation uses blown fibre between the inner and outer leaves of brickwork.
Loft insulation uses rolls of fibre that are laid between the joists and then over the top of the joists.
