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.
Dow Tuff-R™ PIR general application board should be described in specifications as:–
The insulation shall be Dow Tuff-R™ General application board ____mm thick comprising a premium performance CFC/HCFC–free rigid PIR (Polyisocyanurate) thermoset insulation core with 12.5 micron tri laminate, autohesively bonded foil facings on both sides conforming to fire tests, AS1530–3,
DOW Insulation Limited and shall be applied in accordance with the instructions issued by them.
