How does glass facade durability compare with aluminum or stone cladding in harsh environments?

Durability is a function of material properties, detailing and maintenance regime. Glass facades paired with metal curtain wall systems deliver predictable performance when IGUs, sealants and aluminium finishes are specified for local exposure. Glass is susceptible to edge seal failure and coating abrasion in sandy or saline environments; selecting robust edge seals and sacrificial cleaning regimes mitigates these issues. Aluminium cladding (PVDF-coated) resists UV and salt spray and is lightweight and repairable; however, finish chalking and abrasion occur over decades. Natural stone offers longevity and thermal mass but increases dead load, complicates anchorage and may spall under freeze-thaw cycles common in Central Asian highlands. Repairability favors metal curtain wall systems—spare panels and modular replacements reduce downtime compared to stone. For coastal Gulf projects, corrosion-resistant fixings and duplex stainless steel extend service life across systems. Ultimately, a balanced approach—glass vision areas with durable aluminium spandrels and tested sealant systems—often provides the best combination of aesthetic performance, repairability and lifecycle cost in harsh climates.
