Dual-Zone Indoor Shades

Dual-zone indoor shades reduce glare and heat gain by integrating two separate daylight control strategies into a single unit.

An upper louvered blind that maximizes daylight harvesting
A lower roller shade that controls glare and reduces heat transfer

Research by the Lawrence Berkeley National Laboratory (LBNL) found that the shades offer increased daylight and unobstructed views, which increase occupant satisfaction and productivity.
