Around 35% of the heat in your property escapes through the walls.
Save money on your energy bills by reducing heat loss.
Why cavity wall insulation matters
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. At Viridian, our cavity wall insulation installers are fully trained to an NVQ standard, with specialised gas safety training and CSCS cards.
The benefits of cavity wall insulation
Properly installed cavity wall insulation can help with:
- Lower energy bills: Without insulation up to 35% of your home’s heat can be lost through the walls, leading to increased heating costs. According to the Energy Saving Trust, a typical home can save up to £410 each year on heating bills. This amount depends on the size and type of the house.
- Improved comfort: Cavity wall insulation helps to maintain a consistent temperature in your home throughout the day. During summer, it can also keep the heat out, ensuring that your living environment remains comfortable year-round.
- Reduce carbon emissions: Lower energy consumption leads to fewer carbon emissions, so your home will be more environmentally friendly.
- Improved EPC rating and enhanced property value: Energy-efficient homes can be more attractive to potential buyers.
Using premium insulation
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.
Fast and efficient installation
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.
The benefits of using a cavity wall insulation installer
- Long-lasting results: When installed correctly by professional cavity wall insulation contractors, the insulation is designed to last. Once the installation is complete, you can enjoy better energy efficiency and lower heating costs for many years.
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.
- Reduction in condensation: Cavity wall insulation can also help to reduce condensation problems in your home. Keeping the internal walls warmer stops moisture from forming on cold surfaces. This helps prevent damp patches and mould.
