What is the fire rating of aluminum curtain wall systems?
Fire performance of curtain walls in Gulf skyscrapers—common in Dubai or Doha—is governed by local codes (e.g., UAE Fire and Life Safety Code) and international standards (ASTM E119, BS 476). Aluminum framing itself is noncombustible but must be combined with fire-rated glass (20, 45, or 60 minutes) and intumescent glazing gaskets to achieve full system ratings. Spandrel panels containing insulation—such as mineral wool or calcium silicate—must match or exceed the fire-resistance period. Vertical and horizontal fire barriers at floor lines prevent fire spread between stories. Third-party certification from UL or Intertek verifies compliance. Integration with aluminum ceiling systems requires coordinating ceiling tiles and grid components to uphold the same fire-rating at soffits. Maintenance teams in Saudi Arabia and Oman perform annual mock fire tests to ensure integrity.
