Install Step by Step
-
Assessment – A surveyor inspects your property to check wall types, condition, and suitability for insulation.
-
Preparation – Fixtures, fittings, and radiators are removed from the walls being insulated. Any repairs or damp issues are addressed before work begins.
-
Fixing Insulation Boards – High-performance insulation boards are securely fixed to the inside of your external walls, either with adhesive or battens.
-
Sealing Joints & Gaps – All joints, edges, and gaps are carefully sealed to prevent draughts and ensure a continuous thermal barrier.
-
Plasterboard Finish – A layer of plasterboard is fitted over the insulation, ready to be skimmed and decorated like a normal wall.
-
Reinstating Fixtures – Radiators, sockets, and other fittings are reinstalled neatly.
-
Finished & Efficient – Your walls are now fully insulated from the inside, helping your home stay warmer, more energy-efficient, and comfortable for years to come.

Who is this for?
✅ Homes with solid or poorly insulated walls – Perfect for internal wall insulation, as it adds a strong thermal barrier where none currently exists.
✅ Properties with enough internal space – Best suited for homes that can comfortably accommodate the small amount of room lost when insulation boards are fitted to inside walls.
✅ Properties in good structural condition – Walls should be sound and free from damp or major damage to ensure the insulation performs effectively.
✅ Homeowners looking to improve energy efficiency and cut heating costs – Ideal for anyone who wants a warmer home, lower bills, and lasting energy savings.
