The Sivoia Wired Tensioned Roller Shade is the correct specification for skylights, sloped ceilings, and any window that departs significantly from vertical. The system is engineered to install at any angle from -135 to 135 degrees, meaning it can cover a horizontal overhead skylight or a sharply raked clerestory with the same hardware. Internal cable tension keeps the fabric taut and parallel to the glass at any angle, eliminating the fabric sag that occurs when a standard roller shade is installed off-vertical. The entire system is contained within its frame, eliminating the visible side-cable guides characteristic of other tensioned-shade approaches. Bottom-up operation is supported, which is useful for angled windows where top-down travel would interfere with structural elements. For Florida homes with architectural skylights or complex rooflines, this is the only Lutron product designed for the application.
