[DRAFT project write-up – awaiting Julian’s approval before going live]
A cold external wall makes a room expensive to heat and pushes up your heating bills. On this job in South Molton, we insulated the inside face of the external wall around a window for a warmer home, then skimmed it ready for decorating.
What we did
- Applied dabs of adhesive to the bare wall (the “dot-and-dab” method), ready for the insulation boards.
- Fixed Celotex insulated plasterboard to the wall.
- Skimmed the new boards smooth and finished the window reveals, ready for decorating.
Step by step



Why it helps
Insulating solid external walls from the inside reduces heat loss through the wall, so the room warms up faster and stays warm for longer. For more ways to cut your bills, see our guide to lowering heating bills in older homes.
