Bay windows are among the most architecturally generous features a home can have — and among the most technically demanding to dress. Three faces of glass projecting outward at compound angles, each catching light differently depending on the time of day and the orientation of the home. In this Dartmouth renovation, the bay window was treated not as a decorative challenge but as a performance opportunity — and motorized solar roller shades delivered on every front. Why Bay Windows Demand a Different Approach A standard roller shade is designed for a flat, single-plane opening. A bay window is three openings — typically a wide centre panel flanked by two angled side panels — each of which requires its own independently sized and hung shade. The challenge is making three separate shades read as one cohesive installation rather than three mismatched panels competing for attention. The solution lies in precision: every shade must be cut to the exact width of its respective section, the side panels must account for the reduced depth of the angled returns, and all three must hang at the same drop height so the bottom rails align across the full width of the bay. When done correctly — as in this project — the eye reads a single continuous horizontal line across the bay rather than three individual treatments. 5% Solar Fabric on Multiple Angles: Light Behaves Differently, and That's t…
