Bedroom Window Treatments

Your body produces melatonin in response to darkness, and even low levels of ambient light can suppress this hormone and fragment sleep cycles. Standard curtains and blinds leave light gaps at the edges, top, and bottom of the window, allowing enough ambient light to disrupt melatonin production. Hunter Douglas Duette shades with LightLock side channels use a U-shaped design that absorbs incoming light at the shade edges, removing the bright halos that standard installations leave. Combined with a blackout fabric, LightLock creates near-total darkness even during the longest summer days in Sonoma County, when sunset may not occur until after 8:30 PM.

Duolite combines two independent shade layers in a single headrail: a light-filtering front shade for daytime and a room-darkening rear shade for sleep. During the day, lower the light-filtering layer to enjoy soft, diffused natural light while maintaining privacy from neighbors. At bedtime, engage the blackout layer for near-total darkness. With PowerView Gen 3 motorization, the blackout layer lowers at your bedtime, and the light-filtering layer takes over at your wake-up time, gradually admitting natural light to support your body’s cortisol response. Duolite is available in Duette cellular shades, Silhouette shadings, and Vignette modern Roman shades.

Insulated bedroom shades reduce overnight heat loss through windows by 40% to 60%. Duette Architella double-cell shades with R-values up to 7.0 and U-factors of 0.23 exceed the 2026 Title 24 requirement, keeping bedrooms warmer in winter without increased furnace runtime. Sonoma County winter nights regularly drop into the mid-30s, and a four-bedroom house with Duette Architella on all bedroom windows can see HVAC cost reductions of 15% to 20% during winter months alone. All cordless and motorized Duette options comply with the ANSI/WCMA A100.1-2022 child safety standard.
