Cavity Wall Insulation Brittas is used to reduce heat loss by filling the air space with material that inhibits heat transfer. This creates heat-resistant cavity insulation Brittas that locks heat in and keeps moisture out.
Cavity wall insulation Brittas is one of the best and most affordable ways to improve your home's energy efficiency. Cavity walls are made of two layers with a gap or ‘cavity’ between them. Insulating the cavity space between the outside and inside wall adds a barrier to stop the cold from coming in and heat from escaping.
