Building Envelope Services

Achieve optimal performance and market access for building envelope components and systems with testing, certification and advisory services from UL’s Built Environment experts around the world.

Building envelope testing, certification and advisory solutions to help you compete in a complex global supply chain

Increasingly erratic weather patterns and difficult environmental situations demand more from today’s building envelope products, systems and structures. Designers, building enclosure consultants and manufacturers must continually innovate to protect against extreme weather conditions while meeting increased performance and energy efficiency demand. At UL, we assist your selection of the optimal envelope system characteristics, test building envelope product and system performance and help you navigate regulatory complexity.

UL combines unparalleled building science expertise with state-of-the-art facilities to deliver the broadest range of building performance testing, certification and advisory solutions. In our fully accredited testing laboratories, we simulate wind-driven rains, hurricane and tornado winds, as well as hot and cold extreme temperatures to assess and verify building envelope products and systems before, during and after construction. 

Our experts maintain long-standing relationships with stakeholders in the building materials and construction community. Architects, manufacturers, contractors, consultants, building owners and regulatory authorities rely on us to assess and validate the performance of building products, systems and structures to meet regulatory demands and protect brand value.
