More than 17 years after its release, Engineered Assemblies’ System2 Design Guide continues to set the benchmark for facade detail guidance across North America. By combining proven architectural design with pragmatic installation practices, EA provides a pathway to success.

The guide serves as a trusted framework, detailing how facade systems should be designed and installed to withstand typical environmental conditions. From accommodating thermal movement to preventing moisture entrapment through proper ventilation, System2 addresses the most common causes of failure. Cracked panels, often the result of restricted movement, and moisture damage from inadequate ventilation, remain persistent industry challenges.

Since its publication, over 1,200 projects have successfully followed System2 principles—with no reported material failures due to cracking or insufficient ventilation. This consistency highlights the importance of not just material quality, but correct design and installation.

As extreme weather events increase, improper installations are being exposed more frequently. In many cases, EA is called upon to consult on remediation—even for systems outside its own portfolio.
