Which fire propagation and smoke-control test documents must curtain wall suppliers provide for safety compliance?

Curtain wall fire performance must address both structural and smoke propagation risks. Provide: (a) Reaction-to-fire classification for façade materials (EN 13501-1) and NFPA/ASTM flame spread indices (ASTM E84) for relevant jurisdictions; (b) NFPA 285 (multi-story combustible façade) or equivalent façade fire propagation tests indicating whether the cladding system contributes to vertical fire spread; (c) Full-scale façade fire tests and compartment fire studies where required by authorities to demonstrate smoke leakage and vertical flame spread behavior; (d) Smoke generation and toxicity data (ISO 5660 cone calorimeter) for materials to assess occupant and firefighter risk; (e) Details of cavity barriers, vertical/horizontal compartmentation details, and tested interface assemblies demonstrating maintenance of fire performance; (f) Evidence of compatible firestop and joint systems proven in the same tested assembly; (g) Installation constraints to maintain tested performance (e.g., minimum joint widths, required sealants, and closures); (h) Certification scope and limitations, including configuration variations that void the test result. Include accredited lab certificates, specimen photos, and exact construction drawings of the tested assemblies so fire engineers can confirm the proposed curtain wall meets the project’s fire-safety strategy.
