About Louvered Glazing

Vision Control® is the market-leading louvered glazing solution that can be customized to virtually any shape in interior or exterior glazing applications for unmatched function and performance.

Its advanced louvered glazing technology eliminates strings, ensures alignment and requires no maintenance. In interior applications, Vision Control® and Vision Control® Mini offer complete adjustable privacy and visibility and reduce the risk of spreading infection.

When installed in exterior applications, Vision Control® significantly reduces energy consumption in support of LEED certification requirements.

Let’s discuss your Vision Control® project

Vision Control® offers unprecedented control over:


Vision Control® and Vision Control® Mini manage the quantity and quality of light transmission through fenestration. Thanks to the precise control mechanism, the louvers can rotate 180 degrees, installed horizontally or vertically.


Vision Control® and Vision Control® Mini are the ideal glass solutions for hospitals, clinics, schools, correctional facilities and private offices that require adjustable privacy and visibility levels.


Vision Control® and Vision Control® Mini offer the ideal approach for controlling heat flow resulting from conduction and solar exposure. In exterior applications, Vision Control® provides significant thermal performance and substantial energy savings.


Vision Control® uniquely controls sound far more efficiently than with any other insulating glass unit in the market. Using Vision Control® can help achieve STC requirements that other sealed glass units with separate window treatments cannot meet.

Cord & String-Free Design

Vision Control® and Vision Control® Mini louvers are made of standard baked-enameled Duracron, available in the following colors:

Duracron Metallic Gray K-20794
Duracron Glossy White K-1285

Best suited for exterior applications.

Custom Colors, color-matching

For exterior applications, colors must remain light, not dark, to avoid heat build-up inside the units.


Vision Control® is available in double or triple glazed units and custom-manufactured with any of these glazing types:
– Tempered glass
– Laminated tempered glass
– Low-E glass
– Fire-rated glass
– Lead glass
– Laser protective glass
– Security glass
– One-way mirror glass
– Tinted glass
– Glass-clad polycarbonate
– Standard Polycarbonate and scratch resistant polycarbonate
– Ceramic frit of sandblasted glass
– Printed glass

Various airspaces are available for adaptability in vertical and sloped conditions for a wide range of interior and exterior applications. The spacer houses high-quality desiccant that dehydrates the airspace, ensuring absolutely no condensation inside the hermetically sealed glass unit.

Vision Control®’s primary seal is made of polyisobutylene, which provides high resistance against UV rays. The secondary seal is made of high-quality silicone that acts as an effective moisture and vapor barrier. The contact of both sealants creates perfect adhesion and provides a tight hermetic seal.
