How should aluminum French casement windows be specified for high humidity zones?

In high humidity areas of the Middle East—coastal Egypt, parts of Lebanon and southern Iraq—specifying aluminum French casement windows requires attention to condensation control and corrosion resistance. Thermal breaks reduce cold-frame surfaces that can attract condensation when cool interior air meets warm, humid exterior conditions. Using insulating glass units with warm-edge spacers and low-permeability seals lowers internal dew point risk. Ventilated frame cavities and adequate building-level ventilation help manage indoor humidity, reducing the likelihood of surface moisture on frames and glazing. Corrosion-resistant finishes and stainless hardware guard against accelerated degradation where humidity combines with salt. Additionally, correct installation avoiding thermal bridging into the building slab and ensuring perimeter seal continuity prevents moisture ingress. For hospitality and residential projects in humid coastal zones, manufacturer-backed recommendations and accessory details—such as drip edges and shear-resistant drainage—ensure durable, high-performing aluminum French casement windows.
