The Gunyama Park Aquatic and Recreation Centre redevelopment is now Sydney’s largest pool complex since the Olympics in 2000. The project included the construction of a triple-layer ETFE pneumatic cushion roof over the centre. The ETFE cushioning system is clad amongst Glulam timber beams to create a uniquely architecture roof feature for the centre.
The top and bottom layers of ETFE are 200μm thickness with 80% and 63% frit respectively, with a 100μm middle layer. ETFE was selected for the roof due to its chemical stability (it will not degrade under UV or chemical exposure), it’s durability (expected life of 50+ years) and its acoustic transparency. This means that when noise is created within the pool environment, 70% of the sound will pass out through the roof, creating a comfortable internal environment. 16003
