What is CWI?
A Cavity Wall is a double wall consisting of two vertical layers joined together by metal ties and a space between them. Installing cavity wall insulation into that space is a great energy efficiency measure to help save on heating bills. It’s installed by drilling into the external walls and blowing insulation materials into the air space, reducing heat loss.
CWI has low thermal conductivity and closed-cell technology, meaning it doesn’t absorb moisture and provides maximum insulation. It’s definitely worth considering to improve your homes energy efficiency.
