Tensile architecture


STFE is a revolutionary solution for creating light-filled spaces.
Its polyarylate mesh provides structural strength to large free span designs, minimizing the need for additional supporting structure. With light transmission of 50%, STFE provides an outdoor feeling and enables grass and other plants to grow.

Structural strength
The polyarylate mesh provides structural strength for large free span designs
As a building skin, STFE disappears and becomes transparent to leave only views to the horizon
Light transmission
50% light transmission - glass-life effect for optimal daylighting performance and plant growth

For an open-air feeling: Walkways, malls, skylights, atriums.


Natural light and UV transmission: Stadiums, arenas

Pedestrian protection: Walkways, pedestrian paths

Natural light and UV transmission: Zoos, botanical gardens, greenhouses

HANDLING PRECAUTION : STFE membrane is delivered with a protective film which one must keep as long as possible during the STORAGE OF THE JUMBO ROLL. THE FILM MUST BE REMOVED BEFORE WELDING and INSTALLATION. STFE membrane must be packed with care and transported as rolls and not bundles to avoid crushed folds which could generate unsightly marks by transparency.

HF WELDING : consider the STFE COVERT TAPE as part of the STFE Fabrication requirement for the warranty.
