Bloc-Baie Chrono one Undercover: the invisible shutter by Soprofen

An invisible chest… and yet accessible from the inside!

This new safe stands out for its aesthetics: the hatch on the inside of the safe disappears. The safe is hidden in the wall to become invisible. Chrono One Undercover thus knows how to be forgotten, favoring the interior design and a refined finish. In the event of intervention, access is easy from inside the home, via the underside of the safe.

Chrono One Undercover retains all the advantages of the bay unit such as assembly on joinery in the workshop, installation in one go without going back to the site and compatibility with the majority of implementations (ITE, ITI, wooden frame), in new construction and renovation. With its apron safely accessible from the inside, it adapts to individual houses as well as to multi-storey collective housing, in complete safety.

Made from 60% recycled PVC, this trunk features:

• an innovative under-surface access hatch with integrated sealing,
• of a honeycomb underside inside which there are removable hinges,
• of a fixed heel allowing the passage of manual maneuvers,
• polystyrene insulation located in the cheeks and in the trunk.

Chrono One Undercover adapts to joinery up to 92 mm thick and the passage width of the inspection hatch (up to 100 mm) makes its apron easily accessible.

The best of Chrono One combined in the Undercover version

In developing Chrono One Undercover, SOPROFEN's R&D teams have risen to the challenge of reconciling aesthetic requirements and performance. Thus, the Chrono One Undercover retains most of the features that make the Chrono One the best bay unit on the market.

Its patented design gives the Chrono One Undercover exceptional performance in terms of thermal insulation (up to Uc < 0,8 W/m²K* – Delta R 0,31 W/m².K), soundproofing (Dne Atr 50dB* as standard) and air permeability (class 4* certification). The Chrono One Undercover apron acts as a real thermal shield, allowing a window displaying a Uw of 1,4 W/m2.K (open shutter) to go to a Uws 0,98 W/m².K (closed shutter)*.

Benefiting from all the advantages of the Chrono One bay unit, the Undercover stands out with:

• a robust mechanical connection thanks to an aluminum adapter,
• a wide range of reinforcements allowing excellent resistance to wind load,
• an inertia recovery at the lintel compensating for the deflection of the upper crosspiece of the joinery,
• very easy to implement on windows, allowing assembly in less than 8 minutes flat,
• backstage with Goodnight innovation for optimal blackout,
• a wide range of colors (50 coatings under technical advice for PVC, the entire RAL palette for aluminum and other colors on request).

So many possibilities for customization that allow it to integrate harmoniously with all styles of architecture, without forgetting, as an option, the "seaside" powder coating of the slides, the final blade and the aluminum exterior face of the apron. Enough to ensure high anti-corrosion resistance to the whole, guaranteed for 5 years for homes located from 0 to 10 km from the seaside and up to 7 years beyond 10 km!

Finally, let us recall that, like the Chrono One, the SOPROFEN Undercover can be produced in large dimensions thanks to the installation of storm hooks (up to 3 meters or 3,50 meters in a single apron, depending on the 37 or 50 mm ALU blades), regardless of the size of the box (200 or 230 mm). Patented, Chrono One Undercover has everything you need for an ideal bay block box, a real concentrate of performance, with the added bonus of invisibility.
