PIR Tuff-R

Dow PIR Tuff-R™ is as versatile as it is powerful. Dow Styrofoam™ Extruded Polystyrene and PIR Tuff-R™ insulation boards help manage energy loss and moisture, two of the most costly issues facing homeowners today. The Dow PIR Tuff-R™ insulation boards feature the highest insulation value of any foam sheathing available.

Dow Tuff-R™ is a closed cell PIR foam core sandwiched between two durable, aluminium foil exterior facers. The first is a continuous sheet of aluminium foil, the other is Aluminium foil-Kraft Paper-Aluminium foil.

Air cannot penetrate the facers, which also minimises water and water vapour intrusion into the foam insulation core, and allows the foam R-value to stabilise at a higher value.
