How should Gypsum board ceilings be specified to meet local Saudi building codes?

Specifying Gypsum board ceilings for projects in Saudi Arabia requires attention to local building codes, fire regulations, and environmental conditions in cities like Riyadh, Jeddah, and Dammam. Start by identifying required fire-resistance ratings for each occupancy — many public buildings require 60-minute or higher rated assemblies — and select fire-rated gypsum boards and tested ceiling assemblies accordingly. In coastal or humid areas, specify moisture- and mold-resistant boards and corrosion-protected suspension hardware. Ensure that acoustical and thermal performance expectations are documented, and use tested assembly STC and ASTM/EN ratings where relevant. Coordinate penetration details for sprinklers, lighting, and HVAC with MEP discipline to maintain firestopping and smoke-sealing continuity. Provide maintenance access panels at logical service points and specify installation tolerances in contract documents. Finally, work with a local gypsum ceiling manufacturer familiar with Saudi authorities having jurisdiction to supply documentation and assembly test reports to support approvals. This approach ensures compliance while delivering the performance and aesthetics expected by regional clients.
