Used between furring strips
I didn't use this over sheathing but in my 1950s furring strip on cinder block home. With the furring strips, there is not much room for insulation but when I re-modeled the bathroom, this 3/4" thick insulation fit great in between the cinderblock, furring strips and drywall. It doesn't have much R value but anything helps in my cold house. Ive noticed a slight different in insulation.
I used a utility knife to cut up. The foam is messy despite how sharp your blade is.

Great for blocking knitted items
I needed a surface to block knitted items. This board works great. Accepts pins well. Lightweight and rigid, stores vertically.

The versatility of this product met my needs amazingly well.
It was large, it was ridgid, it was light, it was affordable, it was paintable--it was just what I needed for making two backdrop stages for a vacation Bible school. Admittingly it was an aberrant use of foam insulation, but the kids loved it!
I peeled off the foil, laid 5 piecies on the ground, drew and painted the scene, then turned them over and connected them with duck tape. Then stood them up.

I acquired this Foam Insulating Sheathing to partition off a portion of a space for the reason of creating an environment within an environment . It is light weight, and flexible and is sheet sealed to aid with cleaning, and the mirrored silver finish adds a brightness to the overall effect of the micro-environment . I find this product to be simple to work with and highly effective. I am sure that I will buy more in the next 6 months
