A Systematic Approach The THERMAX™ Wall System is more than an insulated wall – it's a systematic approach to achieving efficiency at every level: simplified design, streamlined construction and optimized energy consumption for a reduced carbon footprint. Dow's three-in-one system with insulation, flashing and air barrier meets all applicable IBC and ASHRAE requirements. Each component of the THERMAX™ Wall System was selected to serve a particular function in the wall assembly. Together, these three simple parts – insulation, flashing and air barrier – work as one integrated system.

Continuous Insulation:
Backed by more than 30 years of proven performance
Features better product consistency, durability and fire performance
Provides one of the highest R-values available
Six-month exposure rating

Air Barrier:
Effectively blocks air infiltration by filling gaps, cracks and penetrations
Exceptional moisture management
Elimination of air infiltration in the wall
Class A fire rated

Flashing:
Protects the wall assembly from moisture entry
Delivers adhesion, maximum quality and performance over a wide temperature range
