Building envelope services for performance and compliance Field tests can help you mitigate risk, reduce unexpected costs from potential performance issues and establish trust in your building envelope systems.

Work with UL to gain confidence that installed fenestration and building enclosure components and assemblies meet performance requirements and identify the sources of issues that need remediation. 

The value of Field and On-Site testing

UL’s full-service independent laboratories in the U.K. and North America, staffed by field testing experts, can conduct on-site assessments to determine compliance with key building requirement standards, including the Centre for Window and Cladding Technology (CWCT), Canadian Standard Association (CSA), American Society for Testing and Materials (ASTM) and American Architectural Manufacturers Association (AAMA). We test in accordance with the requirements of warranty providers such as National House Building Council (NHBC), Premiere Guarantee, Tarion Warranty and Local Authority Building Control (LABC).

We conduct testing at varying stages of building construction and throughout the lifetime of the building. This allows us to evaluate elements of the building enclosure installation performance and compliance to industry standards, warranty requirements and project specifications. We also conduct testing on existing structures to identify the sources of air and water leakage to allow for remediation of any potential issues.

Experience the UL advantage

UL’s highly qualified and adaptable building envelope teams can provide you with the expertise you need to experience a seamless testing process.

Our longstanding relationships with the design and construction community, regulatory authorities and industry technical leaders has enabled us to test a multitude of building types and build trust within the industry.
UL LLC is accredited by IAS as an ISO/IEC 17025 Testing Laboratory and by the American Architectural Manufacturers Association (AAMA) Laboratory Accreditation Program.
