Up to 25% of your home’s heat escapes through the walls and insulation can reduce this significantly, saving you hundreds in energy bills. However, it’s not a DIY job and you will need to choose your installer carefully to ensure you get a professional, registered installation. The process usually takes around two hours for an average house with easily accessible walls, and shouldn’t make any mess. You should be able to recover the installation cost in five years or less through your yearly energy bill savings.Read more:cavity-wall-insulation.uk
Cavity wall insulation installers will drill holes into the mortar line of your outer brick walls at strategic points, then insert the insulating material – usually recycled granulated mineral wool fiber or polystyrene beads (or both) – to fill the cavity and inhibit heat loss. This creates a blanket effect that stops the heat from escaping so your heating doesn’t have to work as hard to keep your property warm and can save you up to £290 per year based on a detached house.
The Importance of Professionalism: Selecting Reliable Cavity Wall Insulation Installers
Before choosing an installer to carry out the survey on your property, check that they are registered with a recognised trade body and have customer reviews, and are compliant with all current fire/safety regulations. Westville only uses a mineral wool product type that has an insurance backed guarantee so you can feel confident your property is safe and secure.
To find out if your property is suitable for cavity wall insulation, ask the installer to carry out a borescope inspection. This involves drilling a hole into the wall to inspect the masonry and brickwork to ensure it’s in good condition and that the cavity is at least 50mm wide, and free of rubble or foreign debris.
