Tuff r polyisocyanurate insulation consists of high performance high r value closed cell polyisocyanurate foam core boards sandwiched between a choice of durable exterior foil facers.

Foil faced rigid insulation fire rating.

On tuff r insulation one facer is a continuous sheet of aluminum foil. Rigid foam insulation packs a lot of r value into a thin package but not all rigid foam performs the same. Iko enerfoil sheathing wall insulation is a rigid polyisocyanurate foam insulation board with high thermal properties. Depending on whether or not the foil backing on the existing foil backed gypsum board is perforated or not the perm rating of that surface could be near zero that is very resistant to moisture movement forming a moisture barrier in the wrong place.
