I am soon to embark on insulating my pitched roof garage.
there is no overhang, the pre-formed trusses sit on top of wooden beams sitting directly on top of the single skin walls
I will be plasterboarding a ceiling and piling it with rockwool type insulation.
As there is a lot of wood being sealed away up there I am concerned about ventilation (it's currently open of course).
My plan is to put an airbrick (plus insect screen) in each of the "gable ends" - SEE PICTURE
Any comments guys?
thanks
