Bit of an odd one. Helping a friend look for a boat, found an old Malcom Braine Tug in need of a bit of work but with good bones. Thing is as far as I can tell without digging holes in the wall it looks like there’s no insulation layer between the v solid T&G lining and the steel work. Not quite sure what to make of that. Anyone had any experiences or can cast a bit of light?
Not too worried about the warmth aspect to be honest, all small spaces and stoves should do the trick but that’s all I’ve got as far as a perspective goes! Also during my youff I’m fairly sure I was on several boats without insulation but I was young and it’s all a bit fuzzy:)
