Our 1870 house has solid brick walls which have about the same u-value as leaving the window open!
The two normal options are to build an internal stud wall with insulation inside the walls, or to insulate the external walls. The 2nd option we just don't like, certainly not right now - the former loses some room space but would be an option in some rooms.
However our main living room has original, ornate coving and pulling the walls in 6" would ruin that. We would rather keep it than reproduce it.
It looks like we could lose 1-2cm of wall and blend it in just fine so I wondered if there would be any benefit to getting thinner insulating sheet material of this thickness. I don't know what's out there but am thinking some kind of hard foam sheeting we could panel with then skim/paint/paper as normal.
Does such stuff exist and would it make any detectable difference? Maybe it's something worth doing when we redecorate as it wouldn't add much time... in fact if we removed the plaster we might then have a good inch to play with if we affixed such a product to the bare brickwork and could skim on top?
Is this something people ever do? Any products I could look into?
