Hi
I currently have a fairly large garage and am looking to make part of it slightly more comfortable as a sort of home office (basically my wife and I are teachers and need to have some quiet time for marking/planning etc and we also want to keep school work out of the house). So this will involve construction of a partition wall and then upgrading the existing within the new “room”.
At the moment the garage is constructed as follows from outside to inside…
Floor – Concrete (unsure of depth and doubt the existence of a DPM although the garage is bone dry
Walls – Prefab concrete section -> 50mm Celotex style board -> Plasterboard -> paint
Flat Roof (well slight pitch…) – Torched on felt -> OSB resting on rafters (there is 50mm Celotex cut to fit between rafters and this is tight up against the roof.
My initial thoughts are
Floor – 75mm EPS -> OSB -> Carpet tiles
External Walls – Add 25mm battens and 25mm of EPS then standard plastboard, plaster and paint add double glazed window (with trickle vents and escape provision) to one wall.
NEW Partition wall – 3x2 frame with 75mm EPS and fireline plasterboard garage side and normal internally
Roof – add 75mm EPS to fill remaining space between rafters then plasterboard (vapour barrier stuff) then plaster and paint…
Can anyone see any issues here?
Would I need to have breathing space anywhere in the ceiling layers? (the garage is currently heated to a very low level and there is no condensation that I can see)
Do I need to add vapour barriers anywhere or use vapour barrier plasterboard as an alternative?
Thanks in advance…
