Air, Water, Vapor, and Thermal protection all in one.

The DuPont™ Thermax™ Wall System (TWS) 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.

DuPont™ ArmorWall™ Systems incorporate five traditional building enclosure elements into a composite panel product: structural sheathing, fire-resistance, air barrier, water-resistive barrier, and a high-performance continuous insulation layer.

The five-in-one system is available with either DuPont™ ArmorWall Plus Fire-Rated Structural Insulated Sheathing (SIS) or DuPont™ ArmorWall SP Plus Fire-Rated Structural Insulated Sheathing (SIS) and includes ArmorBoard Plus Structural Sheathing Returns and ArmorSeal accessories as part of a complete system. As innovative products in the industry, DuPont™ ArmorWall™ Systems can replace several traditional individual components that, on their own, add cost, labor, and complexity to a project.
