Tunnel boxes

Sunon Blinds offers a system of tunnel drawers for rolling and adjustable shutters with maximum thermal and acoustic insulation. This system, with a thermal coefficient of 0.23 W/(mK) and acoustic resistance up to 50 dB, exceeds traditional systems. Sunon tunnel drawers are easy to adapt to architecture and mounting, ideal for large or heavy blinds.

The ST200 model, made of polystyrene and reinforced with zinc steel, offers great acoustic insulation and is easy to install in any construction. The ST300 and ST400 models are designed for large blinds, with superior thermal and acoustic advantages.

The PVC register covers with polystyrene insulation are easy to extract for maintenance, and the Sunon integral system is compatible with all the doors and windows on the market. This provides optimal insulation thanks to its expanded polystyrene panels and fibrocement finishes.
