Foam board insulation is flammable and code here says we have to cover it. I have it in my basement and it really helped. If you also have to cover it you can use paneling. I used 1/2" (31.75mm) foam board and it worked.

For the ceiling You might want to investigate 2"x6" (50.8mm) studs, 6" (152.4mm) fiberglass insulation covered with dry wall:

This should keep the room warmer.

FWIW I would solve the heat loss problem first then attack the acoustic problem second.

PS - I am assuming that all of the products that I mentioned are available in the UK.


Thanks MarioD, as mentioned above, I'm concerned how narrow the room will get if I pack the walls with insulation and acoustic foam or boards as well.
