ETFE
Lightweight. Transparent. High-Performance.
LEAF Structures is one of the only companies in South Africa offering fully integrated ETFE design-build solutions. We specialize in delivering advanced ETFE systems for skylights, canopies, atriums, and specialty façades.
What is ETFE?
Ethylene Tetrafluoroethylene (ETFE) is a fluorine-based polymer formed into a highly transparent extruded film. It can be installed as a single-layer membrane or as a multilayer, pneumatically inflated cushion system.
ETFE offers exceptional performance while maintaining a lightweight and visually striking appearance.
Key Benefits of ETFE
ETFE combines exceptional performance, durability, and design flexibility, making it a high-performing solution for modern architectural applications.
High Transparency & Light Control
ETFE allows abundant natural light while maintaining clarity. It can be digitally printed to control solar gain and light transmission. Custom patterns help optimise energy performance.
Lightweight & Efficient
ETFE is much lighter than glass. This reduces structural requirements and minimises joints. Installation is faster and more efficient.
Durable & Sustainable
ETFE offers strong UV stability and chemical resistance. Its anti-adhesive surface reduces dirt build-up. The material is fully recyclable.
Fire Performance
ETFE performs well in fire conditions. It withstands temperatures up to 200°C and melts at 270°C. It does not significantly add to a building’s flammable mass.
Installation Process
In most applications, ETFE is installed using net systems.
For skylights, canopies, and roofs, nets provide a cost-effective and practical solution, especially for refurbishment projects where work must continue below.
Installation Process:
The primary steel structure is installed.
Nets are attached to the structure, allowing installation teams (secured with safety harnesses) to mount aluminium extrusions and ETFE panels.
Once installation is complete, the nets are removed.
This method ensures efficient installation with minimal disruption to surrounding activities.
