Customer Questions & Answers

What side should the reflective side face, towards outside or inside?

Asked by: jm
Easy way to remember is, shiny side (foil) outside toward sunshine. Inside face outside, it's much easier to work with that way.

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

Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.
