Thermax™ Wall System (TWS)

The DuPont™ Thermax™ Wall System (TWS) is more than an insulated wall – it’s a systematic approach to achieving an all in one thermal, air, and water barrier system.

Simplified design, streamlined construction and optimized energy consumption for a reduced carbon footprint.
