Hallo,
I'm in the process of acquiring an older mid terrace with solid external walls. We would like to put up internal insulation on the solid walls. There isn't any evidence of damp, I see Kingspan K17 can be dot & dabbed. What are peoples thoughts on this VS putting up batts? If i went with batts and left a void between the wall & the insulation does this have to be vented some way? I don't see the point of an air gap if it's sealed.
Also, see screengrab below, it looks like there'll be a significant thermal bridge at the interface between the existing house & a cavity walled extension that was built. Is this likely to be a major issue or would it be insignificant because it's so small?
picture A here: whatever finish/render is on it is crumbling at the bottom, but it's dry and powdery and doesn't clump or stain. I'm thinking this suggests the wall doesn't have rising damp? I'm assuming with the age of it there's no DPC.
It looks like someone has taken half of a brick out of the neighbor's house for a gander. Same story here; the inside of the brick is quite powdery but it's a dry & dusty rather than sticky / clumpy. I've no idea what a damp brick / render looks or feels like so any thoughts / suggestions welcome.
Finally, the walls to the neighboring house are lined with some kind of MDF-ey looking stuff. Looks like the vendor has removed wallpaper and taken the surface of this stuff with him. It's in bad shape, I was thinking we'd replace with plasterboard. Anything weird or wonderful we should know about this stuff before we take it off?
