Keeping homes warm while cutting energy bills is the aim of most homeowners, and one way to achieve this is by installing cavity wall insulation. This is a relatively simple process, but there are a few factors to consider when choosing the right installer.

Before the Cavity Wall Insulation Installers begins, the property must be assessed by a qualified surveyor to see whether it’s suitable for the treatment. This will also identify any pre-existing issues. If the property is deemed to be suitable for CWI, an installer can then begin the work.

DIY vs. Professional Cavity Wall Insulation Installation: Pros and Cons

First, the walls must be prepared by cleaning them and sealing any cracks to prevent damp and air leakage. Next, access holes are drilled into the external wall at intervals to enable the chosen insulating material to be pumped or injected into the wall cavity. This is normally a mineral wool, polystyrene beads or polyurethane foam insulation that expands upon injection to fill the cavity and stop heat loss.

Once the insulating material has been pumped or injected into the cavity, it must be sealed and completed with a final fill to ensure no gaps are left. The installer may also fit extra ventilation to help avoid the build-up of moisture within the walls and reduce any potential damp problems that could arise in the future.

Installing cavity wall insulation can significantly cut heating costs, with some households saving up to PS255* a year on their heating bills. It can also improve soundproofing, making your home a quieter environment to live in. In addition, CWI can increase the value of a property, as it’s seen as an energy-efficient upgrade.
