Siam Center Bangkok
Located near Siam BTS Station in central Bangkok, Siam Center is one of Thailand’s earliest international-standard shopping malls. As part of its rejuvenation, the food court was upgraded with a three-layer ETFE cushion roof, creating a brighter and more comfortable environment for visitors.

Siam Center Bangkok – ETFE Roof Brings Daylight to Retail Dining
The ETFE roof uses a white top foil, allowing sunlight to create a soft natural glow inside the mall during daytime. This reduces the need for artificial lighting and contributes to operational savings while improving the atmosphere of the dining area.
Beyond daylight, ETFE offers acoustic transparency, an important advantage for crowded food court environments.
With a mass of less than 1 kg/m², the material allows sound to pass through rather than reflecting it back into the space, unlike conventional materials such as glass.
This helps maintain a comfortable acoustic environment where large numbers of visitors gather.

Natural Daylight for Retail Comfort
Lightweight Roofing for Mall Renovation
The lightweight ETFE and steelwork system helped deliver structural efficiencies and cost savings. Following the success of earlier ETFE installations for the same client, the material was selected again as the roof solution for Siam Center’s renovation.
