PIR Tuff-R

Details

Featuring the highest thermal insulation value of any foam sheathing currently available, Dow Tuff-R is a closed cell polyisocyanurate (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 polyisocyanurate foam insulation core, and allows the foam R-value to stabilise at a higher value. Dow Tuff-R thermal insulation can be easily applied to a variety of substrates.

Dow Tuff-R thermal insulation is a rigid board, manufactured with a HFC blowing agent, which has zero ozone depletion potential (ODP) than standard CFC/HCFC blowing agents and is Green Star Compliant.

Applications

Car park soffits, concrete roofs
Tuff-R is not compliant in exposed applications where AS ISO 9705 determined group classification is required. Examples are where required by Melbourne Fire Brigade or buildings approved under the NCC 2015.
Double brick wall, cavity wall, double cavity precast wall, masonry wall external
Underside of slab
