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
