What are the main considerations for fire-rated aluminum curtain walls in high-density buildings in Bangkok?

Fire-rated curtain walls in high-density urban contexts require integrated strategies that address compartmentation, smoke migration, and structural fire performance. Aluminum curtain walls themselves are non-combustible, but the overall façade assembly must prevent vertical fire spread between floors and adjacent units — an issue especially critical in dense Bangkok or Dubai neighborhoods. Firestopping at slab edges using fire-rated seals, intumescent strips, and fire-resistant mullion covers creates floor-to-floor compartmentation. Spandrel assemblies should employ fire-rated insulation and non-combustible back-up panels to maintain continuity. Smoke control is equally important: pressure differentials and smoke baffles in vertical shafts prevent smoke from entering occupied spaces, and vestibules with controlled openings help contain smoke migration. Egress and access points require coordination with façade openings like doors and operable vents to ensure that life-safety systems are not compromised. For high-rise hotel or residential towers, glazed fire doors, rated vision panels and tested interfaces between curtain wall and internal firewalls must meet local code requirements in Thailand, and similar rigor applies for Singapore and Gulf regulations. Selecting tested products and documented assemblies simplifies approvals; early engagement with local authorities and fire engineers expedites compliance and reduces costly redesigns during construction.
