NON cavity wall insulation, methods?

(1/3) > >>

Happy new year everyone!

Having recently bought a house which is 1930's built, it is noticeably colder than our previous one. It has 9" solid brick walls and a tendency to grow mildew spots in corners of rooms!

Can anyone recommend a tried and tested method of internally insulating rooms with outside walls........... Please.

I have heard about fixing battens down the walls then plaster boarding over them, leaving an air gap behind or cavity behind. Sounds like a good idea but will the damp not still grow in the cavity on the inside of the external wall?

Any ideas welcome!

Aaron,
we live an even older house so have had similar problems.
Last year we insulated the longest wall in our bedroom by battening with 2" vertical timbers and cross pieces, infilled with 2" thick wool insulating "bats", then covered with silver backed plaster board. This has made a huge difference to the temperature of the room. The wool is unaffected by any damp, but we are told that because the inner face of the wa;ll is now covered it won't get damp anyway.
This year we have just done the same on 2 walls in the kitchen and are noticing the difference already.

Mutz:
Kingspan thermal boards.

You can buy plaster board with insulation already fixed to back. neither of which are cheap, but its the correct way of doing it.

Aaron, your problems are probably caused by the heat you are producing hitting the cold walls and causing condensation/mould, if these are insulated it should stop the mildew; but you would be better having airflow behind the panels.

Are you still in Norwich?

T30CDB:
Your mildew spots are caused by the lack of fresh air ventilation. ncover any air bricks in the wall. If there are none put some in high up in each room. The insulated plaster board is the best method by far but not cheap !

aaron:
Hi guys thanks for your comments.

Llanigraham : this sounds like the way forward!

T30CDB : we have vent bricks, in each room upstairs and venting the floor boards downstairs. Our windows are all on vent too, so we should have plenty of fresh air !

Mutz :Hi how are you? Long time no see! We are still living in Norwich just moved over to Thorpe St Andrew. How is the 90 coming on?
