I don't know what we're required to have, SE PA, but I have at least an inch so I think I'm safe. I will find out soon enough.i am required to have a 1" air space between the insulation and the bottom side of roof sheathing here......
Last year, around July-ish. Per my township the homeowner is allowed to produce their own drawings. I was checking them out the other day and there's nothing on there stating anything about insulation, etc. The only thing called out is with regards to needing permits for anything else, i.e. electrical, plumbing, mechanical, etc.wen was your permit aproved?on your drawings did they call out the r values on the wall and roof sections? my permit was pulled last year prior to them updating the code so i fall under the older values. on my permit drwaings he highlighted te note on wall sections and wrote R13 and such. i had a long conversation with the building inspector on this as mine was stick framed with 2x12 rafters for a cathedral cieling- and how to insulate this properly and to achieve the r factor. under the current code this is impossible and now requires te rafter to be padded out or a scissor truss to be used to achieve this......
great links by the way....
