External walls define the boundary between interior and exterior environments, contributing significantly to fire safety, thermal efficiency, weatherproofing and acoustic comfort. NCC 2022 sets strict performance benchmarks for these elements, requiring external walls to be designed and assessed as integrated systems rather than as a set of individual components. This approach ensures that all compliance requirements are met through the coordinated performance of the complete wall assembly.

External Wall Systems and the NCC: A Guide to Integrated Design and Performance provides a useful and practical guide to the key regulatory requirements that impact external wall design. It defines what an external wall is, outlines the role of each system component, and explores how structural, fire, acoustic, thermal and weathertightness provisions under NCC 2022 shape specification decisions. This paper also provides examples of tested systems where compliance and architectural vision work hand in hand.

CSR equips architects with tools and systems to design compliant external wall systems. The CSR System Selector and Thermal Calculator simplify performance evaluation, while the Red Book provides tested fire and acoustic systems for all building classes. Through brands such as Bradford, Cemintel, Gyprock, Hebel, PGH and Rondo, CSR delivers a comprehensive suite of facade and wall solutions.
