Garden Room Insulation

    Seeking advice on this.

    Supplier of garden room (6m x 3m) is going to use 12ml plasterboard and 100ml earth wool, walls and ceiling. Windows and French doors will be triple glazed.

    Its going in a north facing location where no natural sunlight will enter the doors or windows.

    Will the 100ml earthwool coupled with tripled glazing sufficiently insulate the room?

    Nowhere near enough insulation. You'll freeze in the winter and boil in the summer.

    No, they'll freeze in the winter and freeze in the summer. 😀

    Aside from thickness, is earthwool even suitable for vertical applications? Surely it'll slump? Plus cold bridging through the studs.

    I'd be looking for (solid) insulated plasterboard at least.

    It's made from a fibre cement wall, not wood, a box profile steel roof with anti condensation barrier and felt underlay, if that makes any difference.

    what way are you heating or cooling it? they use the wool, as it is far quicker for them... than cutting out endless pieces to stick between the studs , or it could be sprayfoamed. Certainly from the installer side, the wool is the quickest and least hassle... how long do they reckon it will take to build?

    Not sure how long. It'll be heated using a built in electric heater. Cooled by opening windows (3 windows measuring 1800x750mm).

    I agree, the wool is way easier for them. I could request thicker wool, but then it's eating into the floor and roof space (6x3m), 2 metre high at it's lowest point. I've had mixed responses on this, the guys in the thread above saying 100mm in no where near enough, and some friends who say it'll be fine.
