Hi
My end terrace's front room has a 5m x 3m solid brick 9" side wall which I'd like to insulate via IWI (likely 50mm PIR). EWI not possible due to conservation area. Exact method TBD as I'm still trying to digest the Gov.uk IWI Guidance, lots of threads and all sorts of scary stuff about thermal bridging and moisture control.
The front wall is also solid wall but contains a bay with three secondary glazed sash windows plus a front door - basically lots of "fiddly" bits around already lossy areas with just two <1m x 3m areas of "normal wall". It's going to be significant extra disruption and extended labour time to insulate that as well.
Will leaving the front wall uninsulated cause real problems? Is it really worth the extra labour? Or will just insulating the large side wall be OK (as long as I make sure it's sealed properly etc.)
