If your house was built after the 1920s it is likely to have cavity walls, making it ideal for cavity wall insulation.
Do you want to lower your carbon footprint or make your home more energy efficient? Cavity wall insulation is a great way to reduce heat loss, save energy, and lower your energy bills. As a cavity wall insulation contractor, at Viridian we employ our home insulation installers who are fully trained to an NVQ standard, with specialised gas safety training and CSCS cards.
Properly installed cavity wall insulation can help with:
We use Knauf Supafil® 40 – a non-combustible glass mineral blowing wool system which offers excellent thermal performance. It repels water and is BBA-certified, meaning it is a high-quality and reliable product. Knauf Supafil® 40 is rot-proof, durable and non-toxic even in a fire. The installers do not add any chemicals to the insulation during the installation process.
We can install your insulation in any weather, even when it’s below 5°C. It’s effective even for homes often exposed to rain and wind.
Before our cavity wall insulation installers begin work, the team will do pre-installation checks. This includes tests for combustion appliances and ventilation when needed.
We then drill 22mm holes, about the size of a 20 pence coin, into the wall. We use a diamond pattern to make sure the insulation fills the cavity evenly and consistently. Once drilling is complete, we blow the insulation into the cavity at low pressure, filling the wall.
Once we complete this, we fill the drill holes with a mortar that’s similar to the wall’s type and colour. We can’t promise a perfect match, but we aim to blend the mortar as smoothly as possible. Our installers then perform a post-installation check to ensure that we complete all work thoroughly. This will include repeat combustion appliance smoke tests and to ensure that all under-floor and combustion vents are clear.
All first-time full property cavity wall insulation installations will be covered by an IAA 25-year guarantee. Additionally, many removal and replacement works will be, too.
As a credible business, we are members of the IAA’s ‘CWISC’ scheme. If your cavity wall insulation works have been carried out through this scheme (this means you are eligible for an IAA guarantee), you receive two major benefits:
