- living, warm, nice, healthy, ecological… and even more !

- easy to manufacture, simple and quick to implement (without specific tools)



- A unique architectural potential : conceptions with infinite shapes, more than 120 meter long spans (!), an incomparable luminosity with unequal opened areas.

- Exceptional properties
stability and fire resistance (with the growing acknowledgement of the most important insurance companies)
amazing load acceptance regarding concrete material (on traction and compression force) and metal (for the combination span / limited shape)
thermic, phonic and acoustic insulation
chemical neutrality (important in case of ambient contact with some reactive products ).

- As a result, with upper possibilities, a competitive final cost…highly competitive final cost.
