DuPont™ Tuff-R™ and Super Tuff-R™ Polyisocyanurate Insulation products consist of high-performance, high R-value, closed-cell polyisocyanurate foam core boards sandwiched between a choice of durable exterior foil facers. The polyiso-cyanurate insulation is created by an exclusive free-rise manufacturing process, which produces a uniform, closed-cell foam for better insulation performance.

On Tuff-R™ Insulation, one facer is a continuous sheet of aluminum foil; the other is a Tri-Plex facer consisting of a three-ply laminate of durable kraft with aluminum foil on both sides. When additional durability is required, Super Tuff-R™ is the preferred product. One side blue, the other side reflective foil, its Super Tri-Plex facers feature three-ply laminates of durable polyester, kraft and reinforced aluminum foil.

Tuff-R™ and Super Tuff-R™ help reduce air infiltration through the wall by covering cracks between the framing members and sealing tightly against the studs.
