Until now, specifiers have treated glass and shade fabric as separate components of the window system. Glass is selected for performance, while shades are picked for aesthetics and typically treated as a furnishing. Shift that paradigm with this online tool that changes the way window treatment fabric is specified. Shading is an integral part of solar management and building performance. Utilizing five years of extensive research with Purdue University, the tool accounts for several variables on a specific project (climate, location, facade orientation) to determine an optimal solution that reduces glare, maximizes daylight, and preserves views.
