Roof insulation help for shed
Winter has been dreamy in the shed but I’m dreading the return of summer. On a summer arvo the space will hit 35 degrees on a good day, which makes woodworking somewhat unenjoyable. I’ve got insulation in the walls covered with 12mm ply. However, the roof has nothing. The roof is a brown tile and it gets hot! See picture for what it looks like on the inside. Basically I ripped the ceiling out and just have the framing exposed.
I was thinking of getting some R2.0 90mm batts to stick between the framing. 90mm is the width of the framing so any thicker and it would be squished, which I think is not good? Hoping someone can help with a few questions:
Is R2.0 worth it? I think it would make a massive difference even if not the best rating.
What’s the best way to secure the batts? I was thinking some thin metal strips nailed in would suffice?
Is it ok to leave the underside of the batt exposed? I can imagine it collecting mountains of dust in a wood workshop.
There is already this old rubber barrier (sarking?) between the tiling and the frame. Is that enough of a barrier? Is it ok to have the batts resting against that?
