Cavity Wall Insulation Installers carry out surveys and inject or insert insulation materials into properties as part of a home improvement scheme. They may use a variety of different materials including fibreglass, EPS boards, or cellulose, depending on the building type and condition of the pre-existing cavity walls. Getting this work done correctly is essential to ensure the best results. It is important that a surveyor checks the property before the installation is carried out, as damp and structural defects should be addressed before it is possible to fit insulation.

A qualified professional will also inspect the condition of the wall, checking its suitability for cavity filling – not all homes have cavities. It is advisable to get this work done as soon as possible, before the winter weather sets in. It will improve energy efficiency and help reduce carbon emissions, which are responsible for global warming.

It will also prevent air moisture from entering the wall and causing issues like black mould growth. Insufficient or uneven cavity insulation is referred to as cold bridging and can result in higher heating bills, because heat is lost through the walls.

When selecting an installer, make sure they are registered with a recognised body such as the National Insulation Association or the Cavity Insulation Guarantee Agency (CIGA). This will ensure your insulation is installed in line with current building regulations and offers a professional-backed guarantee should any problems arise.
