ETFE Membranes at The Village – Al Jawhara Mall
What are ETFE membranes and how are they used?
ETFE membranes are lightweight fluoropolymer foils made from ethylene tetrafluoroethylene, used for roofs, façades and transparent building envelopes. In architectural systems, several layers can be welded into air-filled cushions, combining low structural weight with high daylight transmission. Lightspan ETFE System explained
The Village – Al Jawhara Mall in Jeddah, Saudi Arabia, demonstrates this approach with 222 Texlon® ETFE cushions, each consisting of three layers. Covering more than 12,500 m², the project was developed near King Abdullah Sports City and forms part of a larger destination with more than 132 stores, a five-star hotel and entertainment facilities.
How do ETFE membranes shape the Al Jawhara Mall roof?
ETFE foil cushions and transparent membrane architecture
The mall combines diagrid and barrel vault-shaped roofs. Diagrid structures can be applied across different scales, including canopies, roofs and façades. For retail environments, the geometry works particularly well with lightweight ETFE systems, allowing daylight into the interior while reducing the structural demands associated with heavier glazing.
ETFE membrane roofs for large retail spaces
The barrel vault-shaped areas provide efficient roof geometry and create large covered spaces. A custom print on the inside of the upper ETFE layer adds a defined visual pattern while also allowing the membrane system to influence light transmission. ETFE foil can be printed or treated to control solar and visual performance. Lightspan ETFE in architecture
Why were ETFE membranes chosen for this shopping mall?
Lightweight roofing and natural daylight
The ETFE roof allows substantial natural light into the shopping environment while keeping the roof system lightweight. Compared with conventional glass construction, ETFE cushions can significantly reduce dead loads on the supporting structure. Lightspan ETFE roofing
ETFE membranes and operational considerations
The low weight and surface characteristics of ETFE can also simplify maintenance and reduce structural requirements. The material is resistant to UV radiation and environmental exposure, making it suitable for large architectural envelopes in demanding climates.
What benefits do ETFE membranes provide at Al Jawhara Mall?
ETFE cushions, daylight and visitor experience
The 222 three-layer cushions create a bright interior environment and support the architectural character of the mall. The printed upper layer adds a distinctive appearance without replacing the basic function of the transparent membrane system.
ETFE membranes and structural efficiency
The lightweight roof reduces loads transferred to the primary structure, while the barrel vault geometry distributes forces efficiently. This combination allows large covered areas without relying on the mass of conventional glazing.
How do ETFE membranes support the project design?
ETFE membranes, diagrid roofs and barrel vaults
Al Jawhara Mall shows how ETFE cushions can be integrated with complex structural geometries. The result combines daylight, low weight, controlled solar transmission and architectural flexibility in one roof system. Further information on ETFE building envelopes and applications is available from Lightspan’s ETFE architecture overview and the U.S. Department of Energy.
ETFE membranes for large-span architecture
The project demonstrates why ETFE membrane systems are used for shopping centres, atriums, stadiums and other large-span buildings where daylight, structural weight and roof geometry need to work together.
Client Benefits
- Enhanced shopping environment: Natural daylight creates a bright interior atmosphere.
- Structural efficiency: Lightweight cushions reduce loads compared with heavier roof systems.
- Low maintenance: ETFE surfaces resist environmental exposure and can be cleaned naturally by rain.
- Distinctive appearance: Printed ETFE layers provide controlled visual effects.
- Efficient geometry: Barrel vaults distribute structural forces while covering large areas.
ETFE membranes – what is the key takeaway?
The Village – Al Jawhara Mall demonstrates how 222 three-layer ETFE cushions can combine daylight, lightweight construction and architectural flexibility across a 12,500 m² retail development in Jeddah.
