We pride ourselves with quality solutions that enhance the building envelope and enable streamlined energy performance. We stand behind our products with industry leading material and system warranties, including our NEW Wall² System Warranties. 


DuPont Performance Building Solutions will reinforce the trusted performance of DuPont™ Tyvek® Commercial products in combination with the durable thermal properties of Styrofoam™ and Thermax™ through the new DuPont Commercial Wall² Ten Year Product and Labor Warranty.

Our portfolio of solutions is designed for robust, durable product performance combined with easy, fast installation for labor savings. We test our products and assemblies significantly above and beyond the building code requirements to give you peace of mind when you choose DuPont Performance Building Solutions.
