Answer This Question

A:  Absolutely, Not sure if it's recommended but it made a dramatic difference at my old home. Difference being pipes freezing vs a pleasant side room.

by|Dec 6, 2018

A:  Absolutely. Long as your furring strips are as thick or more than the insulation sheet.

          A:  I nailed mine into the studs before applying the siding on my house(cedar planks). But from what I think you're saying you want to do, I don't any problem with it whatsoever. Glue it, cut it tight to fit, etc, lay sides on it. It'll be fine, imho.

            Q:Does the R value double when the boards are stacked? Is the R value proportional to the thickness of the stacked boards?

            Answer This Question

            A:  Thank you for your question. EnergyGuard Polyiso Insulated Sheathing’s superior R-value does not double if the panels are installed in two layers. In fact, we do not recommend doubling EnergyGuard. You may wish to view our various Application Instructions here - gaf.com/Other_Building_Products/Sheathing/EnergyGuard.

                        A:  Happen to be considering the same thing, 28'x60' pole barn, 2x6 frame w/2x4 stringers. Roofer quoted me 8-10k to remove leaking metal and replace with shingles. Considering a DIY. Not sure if this material is dense enough to hold a screw so must ensure a stringer or Ladd board is engaged. Good luck with your project.
