Overview of building envelope testing
The building envelope is comprised of all the systems that enclose the building to separate indoor and outdoor environments. The control of air, water and heat flow is of paramount importance. We provide a unique array of services to assess and validate the design and performance of building envelope components, products and systems.
Our experienced and knowledgeable staff understand the science behind the building envelope. Partners in the building materials and construction community - architects, manufacturers, contractors, consultants, building owners and regulatory authorities - trust UL for the knowledge and expertise we provide. Our testing services help ensure performance of building envelope products, systems and structures, meet regulatory demands, and protect brand value.
Our team of highly specialized professionals operate out of global Centers of Excellence based in Chicago, Montreal, Toronto and the U.K. We provide a wide range of services including:
- Building envelope testing
- Fire testing
- Building forensic services
- Building system commissioning services
Benefits of building envelope testing
Assessment, validation and problem solving
Our team of experts is comprised of engineers, architects, technologists and specialists who are recognized as industry leaders in the field of building science. Our state-of-the art testing laboratories offer a wide range of professional services including laboratory and field testing, technical assessments and forensic investigations.
Performance testing of building envelope assemblies
Testing helps enable product manufacturers to meet market and regulatory requirements and construction and design professionals to validate the performance of products and systems.
Recognized by AAMA, NFRC, CSA, WDMA, Keystone, NAMI and Miami-Dade, our fully accredited testing laboratories provide performance testing for:
- Curtain walls
- Wall systems
- Full building envelope assemblies
During testing, we evaluate:
- Air infiltration
- Water penetration
- Thermal and structural performance
- Impact from hurricane and tornado winds
- Fire resistance
We can test products and systems in the laboratory, as well as on-site during and after installation.
Our building envelope advisory services include technical assessments and construction commissioning services. Building owners and managers can rely on comprehensive information on the condition of the building envelope, future performance expectations and solutions to maintain acceptable performance for an extended service life.
Why UL for building envelope testing
UL is a single gateway for building envelope testing. We maintain a global network of technical experts, state-of-the-art test facilities, and longstanding relationships with the design and construction community, regulatory authorities, industry technical leaders, trade associations, and universities. This network helps manufacturers gain the compliance credentials they need to compete in a complex global supply chain. It also supports the design and construction community to assess and verify building envelope products, systems and structures before, during and after construction.
“Based upon my experience having been in labs all across the country, the UL lab is state-of-the art. It has the equipment, the people, the overhead cranes and access to Chicago. It has everything you need to test any type of building.”
