Tensile architecture

STFE

Structural and transparent innovative skin for building envelope.
Advantages
Structural strenght
The polyarylate mesh provides structural strength for large free span and minimizes secondary structure. Easier installation and reduced environmental impact.
Transparency
As a building skin, STFE disappears and becomes transparent to leave room to the horizon.
Light transmission
50% light transmission - Natural light and sun glass effect for user's comfort and to enable plant growth thanks to UV.
Applications
Hall in stfe serge ferrari

No feeling of being enclosed in public buildings: Transportation walkway, Shopping mall, Skylight, Atrium.

Stadium

Natural light and UV inputs: Stadium, sport hall.

Pedestrian protection: Walkway, pedestrian path

Natural light and UV inputs: Zoo & botanical garden, Winter garden...

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.
