In brief
Façade materials for Thailand should be selected around sun, rain, humidity, salt, movement, and maintenance, not the colour or material of one panel alone.
Start with exposure
Coastal, urban, and industrial exposures create different corrosion, staining, and sealant risks. Specify for the actual environment.
Evaluate the whole assembly
Glass, panels, framing, fasteners, sealants, and waterproofing must be chemically, mechanically, and operationally compatible.
Plan maintenance
Cleaning, glass replacement, sealant inspection, and drainage access should be planned before construction.
Questions before specifying
Define exposure, expected service life, cleaning method, and future replacement points so material selection reflects whole-life cost, not purchase price alone.
General guidance for product selection. Specifications and engineering details must be verified against each project's drawings and standards.
