Insulate stud wall

BarraOG · 06-11-2019 12:24pm #1

I have a room in the attic where the roof part is insulated but there is a stud wall at the far end that for some reason is not insulated. So this wall consists only of plaster board attached to the 100mm stud. How should I insulate this wall? I was thinking of buying 100mm loft insulation and fitting this between the studs. Is this what you would do?

There are also sockets on the wall. They are mounted onto a piece of timber attached between two studs. Something like this:

Should the area behind the socket be free from insulation or can the insulation cover this board?

Can you get access to the rear of the studs or will you have to tear off the plasterboard ?

Ok you can get metac from isover thet has better insulating values than the equivalent rock wool. Not sure in relation to back of sockets. Rockwool metac etc meant to be highly resistant to fire. Will let someone else answer that for you though ...

I have a similar query to BarraOG.

Stud walls have the plasterboard on the room side and on the attic side there is aeroboard insulation between the studs. Could the insulation be improved by replacing the aeroboard with something else, or by putting plasterboard over the aerobaoard?

Aeroboard is probably the best stuff you can use, provided its fitted tightly.

If you want to improve it, fix some more rigid insulation to the outside of the studs, in a continuous line, as airtight as possible.
However its only of use if you can join it up properly to the roof and floor insulation.

There are far better insulations than aeroboard on the market. Aeroboard is 70s technology

what a difference an "A"

If the whole lot was fitted so well, that the only loss was through the insulation, then, well, maybe we could get to 0.02 :rolleyes:
otherwise the difference is so small, it couldn't be measured.
