Unitized Curtain Walls: Design, Performance, and Construction
Unitized curtain wall systems have become a dominant enclosure strategy, particularly for mid- to high-rise construction, due to their speed of installation, high-performance potential, and aesthetic flexibility. However, these systems also introduce unique challenges related to air and water control, thermal performance, differential movement, and long-term durability. In this webinar, we will provide a technical deep dive into unitized curtain wall assemblies from the perspective of a building enclosure consultant. The session will cover critical design considerations, manufacturing and testing protocols, installation sequencing, common failure modes, and best practices for commissioning and quality assurance. We will also share real-world case studies to highlight lessons learned through design reviews, laboratory mock-ups, and field performance testing.
LEARNING OBJECTIVES
After attending this webinar, participants will be able to:
- Describe the fundamental components and principles of unitized curtain wall systems, including how they differ from stick-built systems.
- Identify key performance requirements related to air and water resistance, thermal bridging, structural movement, and acoustics.
- Explain the role of laboratory and field testing, mock-ups, and site inspections in verifying system performance and quality assurance.
- Recognize common design and installation pitfalls and understand strategies for mitigation during design and construction.
Participants will earn 1.0 AIA CES Learning Unit (LU/HSW) for attending the seminar. Registration is free. Please note that space is limited – email events@sgh.com to join our waitlist if the session is closed when you register.
