Interior Wall Insulation - Advice Needed

    Hi all,

    Basic DIYer here looking to insulate an interior wall in a bedroom and could use some advice.

    There are tiles the far side of the wall. Wall is at at 60 degree pitch internally.

    During the summer the room is a furnace.

    During winter it’s freezing.

    Lot’s of condensation has also led to a recurring mould issue so looking to add a layer of insulation to the wall.

    What would you recommend?

    Would something like the Recticel Polyurethane Insulation boards do the job?

    Something that can be glued / screwed directly to the wall (plasterboard) and ideally painted over is what I’m thinking of.

    Any advice greatly appreciated!

    Hi Murph,

    Condensation can be bad on the pitched wall, particularly under the arrows (in line with window). Tiles on outer side of that wall.

    What type of construction is that? Mansard roof is quite rare in Ireland.

    Knowing how the roof is put together might help plan how you insulate it.

    Now if you are insulating the inside the current finish will go so you might as well take the plasterboard off and start insulating in the wall assuming you can get the required air movement to prevent the frame rotting.

    Wake me up when it's all over.

    Yeah, sees to be a lot of damp in there, are you sure it's not a leak? I'd put a camera in there to have a proper look. Maybe there could be infiltration of warm/damp air from a kitchen too. Needs to be addressed as a whole really as just adding insulated plasterboard isn't going to fix the problem here, but could hide other concerns.
