Cavity Wall Insulation (Wool)

Getting cavity wall insulation installed in your home is by far one of the most efficient ways of saving energy and money. Did you know that without insulation, around a third of your home’s heat escapes through the walls.

Cavity wall insulation acts like a blanket. It traps heat inside your home, keeping your rooms warmer and more comfortable. What’s more, you will be able to turn your boiler down as your house retains the heat.

    Cavity Wall Insulation (Wool) FAQs

    What is involved in the installation process?

    A series of small holes are drilled in the external walls of a suitable property then mineral wool is pumped into the cavity. The holes are resealed, the walls are washed down and any excess dust is cleared away.

    If we are using grant funding to support the cost of your installation then at least 50% of your property will need to be insulated for any work to go ahead. Unfortunately, we are unable to insulate single walls or garages due to funding restrictions.

    How long will the job take?

    Typically an installation will take about 3 – 4 hours for a standard semi detached property. Installation appointments are usually carried out within 3 weeks of an approved technical survey.

    How do you check that my home is compatible with the insulation material?

    Our experienced surveyors will carry out a series of safety checks at your home. We will need to drill a hole inside one of your external walls and use a borescope (a devise that lets you view and measure a cavity) to determine whether or not your home is technically suitable for the work.

    A cavity needs to be roughly 50mm wide in order for it to be filled. Only homes with even cavities that are typically constructed from brick are suitable for mineral wool insulation. There are other insulation materials available for different property types such as spray foam insulation(Technitherm) and external solid wall insulation.

    What guarantees do you offer on cavity wall Insulation?

    All of Edan Homes’ installers provide a 25 year insurance backed guarantee from an appropriate industry body on all mineral wool cavity installations.

    Will my home look different after cavity wall insulation is installed?

    After the holes in your external walls are resealed, our installers will try their best to match the colour of the sealant to the colour of your original brick work. In some cases, air bricks and vents may need to be replaced enabling the insulation material to work effectively and provide a sufficient air flow.

    Our installer’s take pride in their work and will make sure your home is left presentable after hosing down your walls and sweeping up any dirt or dust.
