What are the thermal benefits of a curtain wall system?

A curtain wall system built with high-performance aluminum framing offers significant thermal advantages in arid regions such as the United Arab Emirates and Saudi Arabia. First, the low thermal conductivity of modern aluminum alloys, when paired with thermal breaks, prevents heat transfer from the scorching exterior into cooled interiors. This means lower HVAC loads and energy bills—critical for commercial towers in Dubai or residential complexes in Riyadh. Second, integrating insulated glass units (IGUs) with argon filling and low-E coatings reflects up to 70% of solar radiation before it enters the building envelope. Third, curtain walls can be designed for stack ventilation during cooler evenings in Muscat or Doha, further reducing reliance on mechanical cooling. Lastly, curtain walls seamlessly integrate with aluminum ceiling systems—matching finish and thermal performance—to create a continuous envelope that improves overall building comfort and sustainability.
