Do you have cold solid brick external walls ???
Despite cavity wall construction becoming common place in the 1920's, the bay window wall in this 1930's bungalow didn't have a cavity (unlike the rest of the property). The wall always felt cold and increased the energy required to keep this room warm during winter. Had the wall been straight it would have been relatively straightforward for a builder to install plasterboard faced internal wall insulation, however due to the wall being curved this would make it a little tricky and costly. In addition, the window ledge at the top of the wall didn't protrude enough to accommodate solid insulation and the skirting would need to be reinstalled to the new curved surface.
In the past, polystyrene lining may have been used to provide insulation to the wall, but this dents easily and is now considered a fire risk. So I suggested the use of a modern, safe, alternative - Wallrock Thermal Liner - this was thin enough to not protrude over the top of the skirting so seemed an obvious solution to try before resorting to much more costly alternatives.
It offers:
- 'significantly reduced heat loss and room warm up times'
- 'combats condensation and mould formulation for a healthier home'
- 'covers damaged plaster'
- 'allows your walls to breathe'
- 'sound insulation'
I sanded the wall to remove any significant bumps/imperfections to ensure flat joins at the seams, then using the recommend adhesive, I applied the liner to the wall smoothing it out for even adhesion. Once 24 hours drying time had passed, I trimmed the surplus at either end of the wall and caulked the seams and the top/bottom where it met the window sill/skirting. You could instantly feel a big difference in surface temperature. No more cold wall !!!
