OPALVARIO® OV40 L roller blind system

The OPALVARIO® OV40L roller blind system provides effective and attractive protection against sun and glare. Specially developed for light regulation at computer-screen workplaces, the systems allow a clear view to the outside, combined with glare reduction in accordance with EU guidelines. This effect is achieved by the use of special films with outstanding technical sun-protection performance and a highly reflective outside surface that provides effective heat protection.

The OPALVARIO® OV40L roller blind system features a one-piece cassette (dimensions 54x59 mm). The modular construction with a range of different side guide and cassette profiles, mounts and operating systems allows its versatile use as a variable sun protection system in a wide range of room and office situations.

The blinds are operated either manually, by a ball chain, or by an electric motor, using a wide range of Somfy control units.

The screen material can be selected from a wide range of standard OPALFILM® shade films. The films can be ordered with various light transmission rates, tinting options and surface finishes, to satisfy individual technical requirements and design preferences.
