Guidance Document
Abstract
This guidance document provides practical interpretation of the BCSA Technical Specification for boundary elevations involving capable members in metal wall cladding systems. It outlines responsibilities for cladding manufacturers, including fire resistance compliance, justification of cladding performance under fire conditions, and coordination with steelwork design. The document emphasizes early collaboration between designers, steelwork suppliers, and cladding contractors to ensure structural integrity and fire safety. It also details typical justification considerations, reduction factors for fixings at elevated temperatures, and design approaches for built-up and composite panel systems, supporting consistent and safe implementation of engineered boundary solutions.
