After having my 12 x 20 Amish-built shed for over three years now, I'm finally getting ready to insulate it and move the rest of my woodworking tools from the basement to the shed. So, insulation is the task and I recently noticed a few 'YouTube' videos pushing radiant barrier products. Sounds good, but I'm wondering about the cost and of course exactly where, if at all I should think about installing foil in relationship to the insulation.
I had considered buying 'Roxul' for both its insulation and sound abatement advantages over 3-1/2 inch fiberglass, but both places I checked locally only sell the Roxul by the pallet (I'm still checking around though) and of course it is about twice the price of fiberglass.... still I'm leaning toward the Roxul, if I can justify it.
The shed as a gambrel roof with lofts at each end,, which I've lengthened to five feet deep and I've doubled the joists. The ceiling sheathing is "LP TechShield" which has a radiant barrier on the underside, but I couldn't get the builder to use that for the wall sheathing too.
So the question is, "Should I add radiant sheathing foil to the wall sheathing, and if so wouldn't that go against the sheathing between the studs before I add the insulation? A couple of YouTube video's show the barrier added on top of the insulation, like vapor barrier. My logic (perhaps wrong) tells me that you should reflect the heat before the insulation, not afterwards... but that defies what I see in the videos.
Of course this shed is for part time woodworking. I'm not going to live out there (so my wife tells me anyway), but I do want it easy to cool (A/C) or heat; and, right now it is getting over a 100? in there.
Any experienced suggestions would be greatly appreciated,
