UL Enhanced Architectural Services

UL is pleased to announce Enhanced Architectural Services (EAS), a new fee based service in which UL reviews your project parameters and provides a report describing potential design solutions or an engineering judgement. This service is intended to address situations where the design solution cannot be easily located.

UL Designs

Fire resistant designs are periodically withdrawn from the UL directory. Verify that the desired design is included in the UL directory by checking the online database. Please visit our Architectural Services page to learn more.

Frequently Asked Questions (FAQ) on Fire Resistant Designs



Q. Architect - When wood or metal studs are specified for a design, can larger sizes be used?

A. UL Engineer – Wood and/or metal studs specified in UL rated designs are minimum sizes. Larger dimensional studs can be substituted.


To find general information on all UL fire-resistance-rated assemblies and any allowable variances to individual designs: visit ul.com/architects, click on "Self Service Tools", scroll down to "Design Criteria and Allowable Variances" and click on the type of system you need to research.


Q. Architect – Can I specify a stacked bond pattern for the concrete masonry unit wall design U901? The design specifies “vertical joints staggered” (running bond). Is the duration of fire resistance a function of the joint pattern?

A. UL Engineer – Test reports might shed light on the issue, but due to the proprietary nature of these reports they cannot be scrutinized outside of the testing lab. The wall specimens may or may not have been tested with differing joint patterns. They may have been tested and did not reach the desired hourly rating required by the manufacturer who sponsored the test.  Modifying a design like U901 and the joint pattern would not be permissible since the listing is specific on this issue.

Thinking man.jpgUpcoming Events

  • Fenestration Simulation Software Training: UL's technical expert, Dennis Anderson, will present a two-day course on October 24 -25.  Attendees will learn more about computer simulation of fenestration products using Berkeley Lab WINDOW and THERM software while earning AIA credits. 
  • Architects and Passive Fire Resistance for Buildings: This course will be taught at the Association of Licensed Architects Midwest Conference by UL experts on October 3. Attendees will earn AIA credit while learning more about a building’s passive fire resistance system and how it makes up an all important line of defense against fire progression within buildings.
  • Evaluating the Laboratory and Field Performance of Windows and Curtain Walls of Large BuildingsAIA Chicago Chapter presentation, on October 26 will cover the performance requirements for fenestration products, how products are tested to assess performance and information from supplier to assure performance.
