Total Systems


Cover all the angles for efficiency

Heat. Cold. Condensation. Enemies of building efficiency come at you from all sides. It pays to have a plan to fight back, and DuPont has put together a systematic approach for staying a step ahead.


Combining the strengths of our high-performance water barrier, air sealing, and thermal protection products, DuPont provides a total-package approach to commercial building envelopes. With our portfolio of building materials, you can take create comprehensive solutions that stand their ground in all kinds of conditions.

Commercial Wall² system

DuPont building scientists have worked out all the details for delivering high-performing building envelopes.  Our Commercial Wall “Power of Two” system defines the products and the installation processes that, when used together, can qualify for a 10-year product and labor warranty.

Wrap OVER ci

A solution for either CMU or steel stud frames, our Wrap OVER ci approach applies Tyvek® CommercialWrap® or CommercialWrap® over Styrofoam™ Brand XPS or Thermax™ Brand Rigid Insulation. As a combination, you get a rugged air and water barrier made for commercial job sites along with the proven energy efficiency of continuous insulation.

Inverted Wall

With a layer of exterior gypsum between insulation and wrap, the Inverted Wall assembly is designed for steel stud frames. On one side is the thermal efficiency and durability of Styrofoam™ Brand XPS or Thermax™ Brand Rigid Insulation. On the other side you’re protected by the high-tear strength and UV resistance of Tyvek® CommercialWrap® or Tyvek® Fluid Applied WB+™.

Wrap UNDER ci

We’ve flipped the script, layering the thermal properties of Styrofoam™ Brand XPS or Thermax™ Brand Rigid Insulation outside the building wrap. This approach starts by fastening exterior gypsum sheathing to the steel stud frame, then installing Tyvek® CommercialWrap® or CommercialWrap® D. Assembly is complete using Rodenhouse Grip-Deck® TubeSeal™ Fasteners to secure continuous insulation.

Fluid Applied UNDER ci

By using Tyvek® Fluid Applied WB+™ with continuous insulation, you’ll get the added benefits of a weather barrier made for heavy commercial construction. With Silyl-terminated polyether (STPE) technology, the Fluid Applied system providing advanced air and water holdout and vapor permeability. Similar to Wrap UNDER ci, assembly requires Rodenhouse Grip-Deck® TubeSeal™ Fasteners.
