We don’t install ourselves, but since the start of our business (2016) we’ve created Network of Partners who know our product and can install it smoothly.

Depending on the work area, we can recommend one or more installers.

Steel frame needs to be protected with plasterboard.

We have a range of details that can be put at your disposal. We also have a building technician on our team who can help you with your choice of compositions.

Since our profiles are very thin, we have more room for insulation, and the overall performance will be better than that of a conventional structure (for equivalent thickness).

This may come as a surprise, but framing can be very effective from an acoustic point of view. There are reports of above-average performance (class A) that can be shared.

We don’t yet have French technical approval, but our products have European certification (CE), and our studies and processes are in line with this.

For projects in France, our design office will take into account the French standard and DTU32.1.
