The Beijing National Stadium, often referred to as the "Bird's Nest," utilizes a translucent, waterproof polymer membrane primarily to allow for natural lighting within the structure.1
This architectural choice complements the stadium's unique design, which features a complex lattice of steel columns and struts that lack a traditional outer facade. By using this translucent material, the designers were able to maintain the building's sculptural, organic aesthetic while ensuring the interior remains functional and well-lit by natural sources.1
