[Shop-talk] Shop Insulation

[Jeff Scarbrough]

I'm pondering the next phase of shop construction, adding a ceiling.
One part of the shop is a shed-type roof that's fairly low.  It would
be simple to just put R-19 insulation between the rafters and screw
the ceiling to that.  Something in my head tells me that you need to
leave an air space between the insulation and the roof decking...

Is this necessary?
