Cavity wall insulation problem-advice please

PJ1

Hi All,
My DH & I live in a house that has been converted into two flats-ground floor and first floor. We live on the ground floor. We have a bit of a damp problem in our bedroom on the walls low down-also the flat is quite cold. We decided it would be a good idea to get cavity wall insulation. Because the entire house is basically shared we had to get permission from our upstairs neighbour (he's not especially friendly). However he point blank refused to have it saying it would make the house damp.
My question is would it be possible for us to have our bottom part of the house done without having to have his upstairs part done, so basically how do they fill the walls, is it top down or bottom up etc etc. If anyone knows about this stuff I'd be really grateful if you could give us some advice. Thank you in advance.

Its possible, when a terrace is done a barrier is inserted to stop the insulation between the houses, the same could be done here. I'm not sure its a good idea though, a barrier again the level of the internal floor might well cause cold spots. You need to solve the damp problem before you think about insulation.

Also who owns the freehold, that will that will determine who is responsible for the external walls.

Sorry Phead but you are wrong. Cavity wall insulation cannot be barriered off between flats.

The barriers are for use between terraces/semis only.

The insulation is installed by drilling a pattern of holes around the property to obtain an even coverage of insulation.

If your neighbour is refusing to have the insulation done then im afraid there is nothing you can do about it except look into a different form of insulation. Internal wall would probably be your best bet but it can be expensive so youd have to weigh up whether its worth it.

If I had the choice I would NOT have cavity wall
The cavity is there for a reason.... If I want insulation I would rather put in insulated plasterboard on the extrnal walls and lose 45mm

What is the arrangement with the ownership of the whole structure? Is there a landlord or agent who you pay charges for for external maintenance of the property, or is ownership specifically defined in your lease/deeds?

When doing a house, the fill tends to be stopped at loft level, so it should be possible. But a firm may not want to do it, or guarantee it. But I can't see why not

Phone a few up and see what they say
