Cavity Wall Insulation
Insulation
By working with trusted installation partners, we help deliver reliable results that improve comfort and energy efficiency.
Why Retrofit?
Around one-third of heat in uninsulated homes is lost through the walls. Cavity Wall Insulation (CWI) helps trap warmth inside a property, reducing energy consumption and lowering carbon emissions, while also saving money on heating bills.
Modern installation techniques mean even hard-to-treat cavities can now be insulated, including narrow gaps and certain timber-framed buildings. Domna’s role is to assess suitability, advise on the best approach, and connect you with accredited professionals who carry out the work.
Installations are completed by trusted contractors and typically come with long-term guarantees for added peace of mind.
Grants are available UK-wide for homeowners, tenants, and social housing residents, and Domna can guide you through available options.
A simple upgrade with powerful results – from lower bills to a warmer, more energy-efficient home.
Cavity wall insulation typically involves injecting insulating material into the wall cavity, often using recycled mineral wool fibre or polystyrene beads. The result is a thermal layer that reduces heat loss and keeps the home warmer for longer.
Domna advises on the most suitable materials and approaches for your property and ensures that any works are planned in line with the latest industry guidelines. For hard-to-treat properties, we provide guidance on specialist solutions that meet compliance standards.
Installations are carried out by accredited contractors and are usually supported by long-term guarantees. Domna can also help you explore available funding to reduce or cover the cost of the upgrade.
