Soprofen's One cabinet unit certified NF CSTB for an additional guarantee of quality

Made of 60% recycled PVC, this state-of-the-art built-in safe has successfully passed the assessments and controls carried out by the CSTB according to the NF Closures certification standard (NF 202). It thus meets the high level of requirements expected by the NF mark in terms of performance on the basis of 7 criteria (wind resistance, air permeability, thermal insulation, watertightness, acoustic attenuation,... ).

At the same time, true to its continuous improvement approach, SOPROFEN mobilized its teams to further optimize the certified qualities of its bay unit, which now offers sound insulation of 50 dB as standard. For example, a 200 mm box, in a configuration behind the lintel, equipped with a humidity sensitive 45m3/h ventilation grille, guarantees sound insulation of 46 to 55 dB.

In addition, the excellent inertia of the Chrono One, obtained thanks to various reinforcement solutions, is further improved by the addition of a new external lintel recovery flange. This gives additional rigidity to the upper crosspiece. Finally, in order to ensure optimal compatibility with all frames on the market, SOPROFEN has also enriched the range of aluminum adapters.

With this new certification, SOPROFEN makes it possible for window manufacturers to have their own joinery equipped with an even more efficient Chrono One certified NF.
