Terrace house passage insulation - any ideas?

[Postdog]

I'm getting my house insulated - loft insulation and cavity wall. However, my house is a terrace with a shared tunnel passage, and that wall is only a single wall. This wall does get very cold, probably because of the air/wind going through it. My neighbour uses the passage constantly, and without asking I know they would not agree to closing it off with doors.

Has anyone got any suggestions about what I can do to reduce heat loss on my side?

Hi postdog,

Why don't you dry line that wall? stud it out with 2x1 roof battens insulate between the battens with polystyrene,plasterboard and have it skimmed,will make a hell of a difference, guarenteed, Ray

That sounds a good idea. I was figuring I'd have to add something to the wall, just didn't know what. Ta.

Hi postdog,
If you don't want the hassle of battening the internal wall,you can buy plasterboard with the polystyrene already attached you stick it to the wall with adhesive,it won't take long to do,or plaster, good luck, Ray

There are two problems with drylining:
1) you lose a significant width in your hall, which you will really notice as you carry things in and out (will furniture still fit?). Future purchasers will notice too - it will feel poky
2) it will ruin any original features like cornicing or picture rails in the hall.

I would recommend adding the drylining on the outside in the passage, if your neighbour agrees. Internal plasterboard with a backing insulation will also work, but ultimately it's a all a question of depth and quality of your insulation.

It might be worth approaching your neighbour about adding a door, especially if you volunteer to pay for it and supply free keys. Take the security angle - you're concerned about prowlers breaking in at the back. Also, is the shared passage owned by you or him? One of you must own it, so if it's yours, he only has right of access, and you would be within your rights to add a gate.

If done with roofing battens you lose just over 1" hardly make a difference,he only needs to do one wall,agreed no good if cornice in situ but otherwise the ideal solution.
