Properly installed cavity wall insulation is one of the most cost-effective ways to cut energy bills (often by up to 35%), improve comfort and reduce your carbon footprint. When done correctly it is quick, clean and has almost no impact on your daily life.
At Extract Insulation we specialise in high-quality cavity wall insulation installation across Hampshire and the South of England. As extraction specialists first, we know exactly what goes wrong when insulation is poorly installed. We remove any failed material, prepare the cavity thoroughly, and only then install modern, high-performance insulation that delivers lasting results.
Ideal for homeowners, housing associations and local authorities looking to meet energy-efficiency targets
Our cavity wall insulation eliminates concerns about voids, damp, and mould. It fills cavities consistently, ensuring your energy bills are reduced giving you the biggest return on your investment.
As the cavity wall insulation system does not absorb water and there are no longer voids within the cavity, we cut out any other potential problems that can cause structural damage too.
We are confident that our approach, methods, and choice of materials do work. We are so confident in our insulation system that every customer is given a 25–year guarantee for peace of mind.
