Made for new frame walls or retrofit of existing walls in residential construction, Tuff-R™ features a high-performance foam core sandwiched between durable exterior facers. Rigid and water resistant, Tuff-R™ works in both interior and exterior walls.
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 facerconsisting 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.
Standard Thermax™ insulation board dimensions are 4'x8'. Custom lengths are available up to 30'. Please contact your local DuPont representative for additional availability details or call our product support team at 1-833-338-7668
