When you cut it, Is this a crumbly type of foam or a high density one.

Asked by: Jk
"superior closed-cell, lightweight and resilient expanded polystyrene...." as stated in the specifications online. I would not describe it is high density. It is appears as small white pieces adhered together and some do come loose when cutting but not anything significant when cutting with a sharp knife, such as a new disposable break-away utility knife using a sawing motion. Minimal loose pieces of the foam core detach when cutting and handling. Having cut many window size pieces to insulate single pane windows lightweight R-Tech has proved very good at not crumbling and remaining rigid.

does the sliver coating go to the outside or inside. ?

does the silver coating go to the outside or inside. ?
Asked by: zero70
It goes on what ever side it will have an air gap. With no air gap between the silver coating and what ever else is there It may as well not be there. Radiant barrier only works with an air gap.
