Enclos Tensile Structures (ETS) exists at the intersection of engineering precision and architectural expression. We design, engineer, procure, and install lightweight tensile membrane structures that redefine what a building can be, transforming roofs, facades, and public spaces into high-performance, visually striking environments.

Our work is driven by the  idea that the building envelope should perform, inspire, and elevate the experience of the people who interact with it. Whether through transparent ETFE roofs, durable PTFE membranes, or long-span cable-supported systems, ETS delivers solutions that balance strength, efficiency, and design freedom.

Formed through the acquisition of PFEIFER Structures America by Enclos in 2022, ETS brings together decades of global tensile expertise with the resources and scale of North America’s leading facade contractor. The result is a fully integrated partner capable of delivering complex building envelope systems from concept through completion with unmatched technical depth and execution certainty.

Today, ETS operates across North America, partnering with architects, engineers, and contractors to realize some of the most ambitious structures in the built environment, from stadium roofs and airport canopies to civic spaces and commercial developments. Our vertically integrated approach ensures continuity from early design through procurement and installation, enabling innovation, efficiency, and quality at every stage.

But beyond the systems we build, our work is defined by what those systems enable. Lightweight structures create places where people gather, travel, perform, and connect. They bring daylight into massive spaces, provide shelter in demanding environments, and turn functional infrastructure into architectural landmarks.
