Sealed Blinds from Unicel Offer Flexibility, Low Maintenance

Depending on the needs of a project, the extruded aluminum louvers in the Vision Control system can be fixed in place or mounted in a rack-and-pinion system for rotation by crank handle, thumb-wheel, or motor. Motorized systems can be integrated with daylight sensors or other building-automation systems. Vision Control does not offer up-and-down movement of the louvers. Unlike corded venetian blinds, which don’t fully close, the Vision Control louvers interlock when closed, blocking out 99.9% of the visible light, according to Unicel specifications. Glossy white is the standard color, for good light reflectance, but other colors are available on request.

The louvers sit in a completely sealed and moisture-free 2" (51-mm) space between two panes of glass. Unicel fabricates each sealed-glass unit based on an architect’s specifications, using any type of glass required for a project, including glass with low-emissivity (low-e) coatings, although it avoids soft-coat low-e, which could be scratched by the blinds. Depending on the glass specified, costs can range from $50–$100/ft2 ($500–$1,000/m2) of glazing, according to Viviane Chan, marketing and sales manager at Unicel. The company ships about 5,000 units per year.
