The Ferrari^® Précontraint technology is based on the exclusive use of industrial patents and original techniques for the design and manufacture of composite textile membranes.

The Ferrari^® Précontraint textile membranes are subjected to a pre-stressing treatment throughout the entire manufacturing process (one metric tonne per metre). This gives them 2 unique properties:
- extra long life-span,
- exceptional dimensional stability.

The unique properties of the Ferrari^® Précontraint composite membranes
are unanimously recognised by construction professionals for their benefits.

Exceptional stability, retaining their original shape

- The Précontraint® textiles, and in particular the Précontraint® 502 range, are exceptionally resistant to elongation thanks to a very low absorption level.

- Traditional coated textiles are very absorbent in the direction of the weft.

- The Précontraint® textiles retain their original shape.

- Traditional coated textiles: significant distortion of the weft yarns.

The Précontraint Ferrari^®: extra longevity
and a thicker coating on the top of the yarns

- The Précontraint® 502 Textile - 650 g/m2

- The traditional coated textile - 650 g/m2
