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. On Tuff-R™ insulation, one facer is a continuous sheet of aluminum foil, the other is a durable tri-laminate facer consisting of aluminum foil, Kraft and metalized polyester film. Tuff-R™ helps reduce air infiltration through the wall by covering cracks between the framing members and sealing tightly against the studs.
