Installing Internal Insulation On A Hollow Stone Wall With An Original Fireplace

The house is an end-terrace, estimated to have been built in the 1820s. It has stone walls and an early form of cavity that’s roughly 30mm wide, which seems fairly uncommon for homes in that period. After researching online and scrolling some helpful websites, one suggested method for insulating the interior was to build a frame stood off from the walls, fixed to floor and ceiling battens, with insulation and insulation membrane before boarding. I believe this approach should help reduce thermal bridging and allow for air circulation behind the insulation. I’d love some feedback on whether this is the best solution, considering the odd-ball cavity. The biggest concern is how to handle the fireplace. I'd like to keep it exposed as its original and adds character, but i'm unsure how to insulate around it without risking condensation buildup or compromising the aesthetic. Looking for suggestions and inspirations! submitted by /u/WildcardOilTycoon [link] [comments]
