Window treatments are the one technology layer a client sees every single day. Get them right and the architecture reads calmer, the glare disappears, and the house seems to anticipate the hour. Get them wrong and you have expensive fabric that hums, hesitates, and never quite closes at the same time. The first decision — motorized shades or motorized drapery — sets everything that follows. The short answer Motorized roller shades are the correct default for glare and heat control on large glazing. Motorized drapery is the correct choice where the room needs softness, acoustic absorption, and a finished residential silhouette. In most Charlotte estates we design both: shades in the aperture for performance, drapery on the outside for material and warmth. Light control: openness factor vs. fabric weight Shade performance is governed by openness factor — the percentage of the weave that is open. A 3 percent fabric preserves an outward view while cutting most glare; a 1 percent fabric is appropriate for west-facing walls of glass and rooms with televisions; a blackout fabric with side channels belongs in primary bedrooms and media rooms, where any light leak at the edge undermines the whole installation. Drapery does not have an openness rating. Its performance comes from weight, lining, and return. A lined pinch-pleat panel with a proper wrap-around return blocks more light than most people expect, but only if the track extends past the opening and the panels overlap at the center. Acoustics Rooms with tall glass and hard stone sound bright and unforgiving. Drapery is the most effective acoustic tool available that does not look like acoustic treatment: a fullness ratio of 2.0 to 2.5 across a wall of glass measurably shortens reverberation in a great room. Roller shades contribute almost nothing acoustically. This is the single strongest argument for drapery in open-plan architecture. Hardware, pockets, and the details that decide quality Pocket detailing. Recessed shade pockets must be coordinated with the framer before drywall. A 5 to 6 inch pocket handles most roller assemblies; dual-roller (sheer plus blackout) needs more. Power. Hardwired low-voltage motors are the standard on new construction. Battery motors are a retrofit tool, not a design decision — plan on service visits. Alignment. Hem bars across a wall of windows must track within a fraction of an inch. This is a commissioning discipline, not a product feature. Sound. Quiet motors matter most in bedrooms. Specify the low-noise motor line where the shade opens next to a headboard. What each approach costs Pricing varies with fabric, width, and motor line, but the tiers are consistent. Motorized roller shades generally run from the low four figures per opening for standard fabrics to substantially more for wide spans, dual rollers, or specialty weaves. Motorized drapery costs more per opening in nearly every case, because the fabric yardage, workroom labor, track, and installation are all bespoke. A whole-house program combining both is typically the largest single line item in the interior technology budget after the cinema. Integration is the real differentiator Neither product is impressive on its own. What makes shading feel like architecture is scheduling and scene logic: shades that descend as the western sun crosses a threshold, drapery that closes with the Goodnight scene, a Cinema scene that takes every treatment in the room to blackout in one press. That requires the shading system to be a first-class citizen on the control platform rather than a separate app — one of the reasons we standardize on platforms that treat shading, lighting, and climate as a single scene layer. How we specify it We survey solar orientation before selecting fabric, coordinate pockets during framing, mock up fabric samples in the actual room at the actual time of day, and commission alignment as a punch-list item. The result is a house where the light is managed and no one thinks about the machinery. Peters Audio Video designs and installs motorized shading and drapery systems throughout the Charlotte Metro Area. If you are planning window treatments for a new build or renovation, we can review the glazing package before framing.
