Cavity Wall Insulation
In the UK, a significant source of heat loss in homes stems from uninsulated cavity walls. Exploring the reasons behind this issue and strategies to prevent it is crucial for maintaining optimal insulation and energy efficiency in your home.
What is Cavity wall Insulation?
A cavity wall is created from two separate walls with a hollow space in between. Cavity walls are insulated by a heat-retaining material which is placed in the gap between the two walls. The insulated material traps the warm air from the inside of the building and prevents it from escaping through the outer wall.
How Does It Work?
Typically, cavity walls can be insulated by injecting insulation material into the cavity from the exterior. This involves drilling small holes along the outer wall of your home. Using specialised equipment, the installer then inserts insulation into the cavity. The drilled holes are then filled so that you can’t notice them.
How do I know if my home needs cavity wall insulation?
Some older properties may not have wall cavities, or they may be too narrow to be insulated. At Mantis Energy our team of expert Energy Consultants can carry out a cavity wall borescope inspection for your home. This will determine the cavities depth and if any existing insulation is present. Fortunately, alongside the UK government, some Major energy companies provide free or low-cost grants for home insulation, as part of schemes to reduce carbon emissions and help low-income or vulnerable households. Our team can also check the eligibility of your home for these grants.
