How to choose curtain wall finishes for Middle East heat?

Choosing finishes for curtain walls in regions like Kuwait or Riyadh demands heat- and UV-resistant materials. For aluminum frames, high-performance fluoropolymer (PVDF) coatings in light colors reflect radiant heat and maintain gloss retention over 25 years. Anodized finishes (Class II AE2) offer durable, maintenance-free surfaces that match aluminum ceiling panels for a cohesive interior aesthetic. Glass finishes should include low-iron substrates with spectrally selective tints that block infrared wavelengths while admitting daylight. Ceramic frit patterns provide additional solar shading without mechanical shading devices. Sealants must be silicone-based, conforming to ASTM C920, to endure diurnal temperature swings. For ornate façades—such as those on luxury resorts in Muscat—custom powder-coated colors can be matched to ceiling trims, creating unified branding. Lab testing under accelerated UV chambers verifies finish longevity before field deployment.
