Hello!
I live in a 1918 terraced building site. Everything needs to be done. But mould issues with various people on the street is pushing me to the breathable insulation route.
Tile on sand floor, no DPM, and double brick external walls with a gap that's too small for blown-in insulation.
But the neighbours have used cement renders (one half of our shared chimney is covered with the stuff), regular insulation, and have installed new cement floors (that's out of my budget, btw). I'm worried their methods will be pushing more moisture into my own place. I can use external insulation out the back but not the front. I was planning on using wood fibre boards on the inside of the front wall (and for acoustics on the internal shared walls as they haven't bothered (I'm quiet, they're not) in combination with a centralised heat recovery ventilation system. The floor is a problem. As I said, putting in a new floor, let alone a limecrete floor, is out of my budget). I was thinking of getting rid of the old, battered tiles, levelling the sand, and putting a new layer of unglazed tiles with lime mortar down. But the floor's not so damp, so also there's the possibility of a DPM on the floor and first couple of cm of the walls before insulation and laminate. But if the neighbours have concrete slabs and non-breathable wall insulation, would my choice be able to cope? Or am I worrying about nothing because moisture won't move to my place from the neighbour floor/walls?
Thanks!
Sarah.
