I built my shop ten years ago. At the time it was all that I could afford and I was quite pleased. But over the years my needs and desires have changed and I need to upgrade to a fully heated and insulated structure with good lighting. I can not afford to do it all at once so I will start with the ceiling and the lighting. End and side wall will be done later.
I used an Adams Truss metal frame with wood purlins and girts. The roof and walls are clad with 1" "AgBoard" and a metal skin. All of the joints in the AgBoard were sealed with tape. This
When you look up at the ceiling you see the white underside of the AgBoard and horizontal bays formed by the 2" x 4" roof purlins.
Weight is a big consideration. The ceiling/roof is not engineered to take the load that comes with drywall or OSB sheathing.
My plan is to use the white 28 gauge metal that I used on the exterior of the building.
This will, in effect, create almost air tight chambers between the purlins. I want to insulate this dead space. Can I use unfaced fiber glass bats (the cheapest alternative) or should I use a closed cell foam material in blocks or sprayed in?
