Looking for some advice on a smallish rehab project I am about to start. I've read many of the great articles and Q&A discussions here, so I think have bit of direction...but as I am novice, I am interested in some feedback before I moved forward.
I recently purchased a house in south eastern NH (zone 5) which has a 20 x 40 outbuilding that was used as an antique store back in the 50's. The structure is sitting on a slab foundation and is 2x4 framed with very old fiberglass insulation sandwiched between exterior and interior ship lap, hung vertically. The ship lap is pretty beautiful, its true one inch, width's vary between 8 and 24+. There are no interior walls. Ceiling, if you can call it that, that is really just planks nailed to the cross beams. The interior of the (newish) roof is ship lap as well, there is no sheathing or insulation as far as I can tell
My primary goal is turn this structure into a home office for myself. Secondary goal is to be able to utilize as a guest house down the road. I am going to remove the ceiling and frame a lofted space. My goal on this forum is to kindly seek out the best approach at insulating the space appropriately.
I am planning on having a demo crew take down the interior ship lap (carefully) and cleaning the disintegrating rug off the slab floor. If I had too, id be open to removing the exterior ship lap, but only if it was absolutely necessary to meet the goal.
I have read several of Martin's articles that spoke to this scenario. I recall one article in particular that mentioned furring out the studs, creating an air channel with 1x1's and then using a combination of rigid foam and roxul (I think). That approach might ultimately work, though i the idea of ripping that much foam seems daunting.
I've attached a couple of pictures in the event it helps.
Thanks for any feedback!
