Cavity Wall Insulation Installers

Cavity Wall Insulation Installers survey properties and inject or insert insulation materials into homes, often as part of new builds or retrofits. This is one of the most effective ways to cut heating bills and make a home more energy efficient. The work is relatively safe and doesn’t require much prior experience, but GCSEs in subjects like maths, English or design and technology are often useful. Some employers may ask for experience in construction, such as brickwork, lagging or cladding. An apprenticeship with a construction company is another way to get into the industry.

Cavity Wall Insulation vs. Solid Wall Insulation: Which Is Better

The process of insulating cavity walls involves drilling holes into the outside of the house at regular intervals and blowing in the insulation, which is typically mineral wool or polystyrene beads or polyurethane foam. This is a quick and inexpensive way to increase the thermal performance of a property, saving up to PS145 a year on heating bills and helping the environment.

However, not all properties are suitable for this type of installation and it is important to hire a registered installer who can carry out a thorough assessment before carrying out the works. They will use specialist equipment to check the structure of the wall and look for any gaps which could compromise the effectiveness of the insulation.

Ineffective insulation causes heat to escape through the walls, so your heating system needs to work harder to warm the home, which in turn drives up the energy costs. A grant aided cavity wall insulation installation can reduce this by up to 33% and pay for itself in just over a year.
