How does a curtain wall system perform under strong wind and sandstorm conditions?

Curtain wall systems designed for regions experiencing strong winds and sandstorms—frequent in parts of the Middle East such as the Arabian Peninsula and Sinai—address these hazards through structural engineering, material choice and detailing. Structural calculations establish wind-pressure ratings and deflection limits specific to project location and building height; façades in Doha, Riyadh or Abu Dhabi are tested and specified to meet or exceed local wind codes. Metal frames are sized and anchored to transfer lateral loads safely into the primary structure; flexible connections and slip joints accommodate building movement without compromising water or air seals. Glass selection matters: laminated glass with PVB interlayers resists impact from wind-borne debris and retains integrity if cracked, while tempered glass reduces catastrophic breakage risk. Sandstorms demand abrasion-resistant coatings on frames and careful detailing of seals—high-performance gaskets and concealed drainage paths prevent fine sand infiltration that can abrade seals or mechanisms. Operable elements (vents, windows) are designed with robust locking and sealing hardware to remain watertight and airtight under pressure. Where exposure is extreme, fritted glass or frit patterns can reduce sand spotting and glare, and sacrificial external sunshades can be used to protect the primary glazing. Routine maintenance plans—more frequent inspections after storm seasons in Kuwait and Oman—ensure that seals and gaskets remain effective. When engineered and installed to appropriate standards, metal-glass curtain wall systems provide reliable resistance to wind loads and sandstorm conditions typical across Middle East cities.
