Window Treatments for Luxury Homes: Winter Drapery and Shades

A wall of glass looks spectacular in October light. In January it's the coldest surface in the room.

That's the trade every luxury home with big windows makes, and mid-October is the right moment to deal with it. A U.S. Department of Energy fact sheet from October 2021, built on Oak Ridge National Laboratory testing, notes that nearly 80 percent of U.S. homes still have inefficient single- or double-pane windows, and only about 2 percent of those homes get more efficient windows each year. Replacing glass is a renovation. Dressing it is a fall project, and the right shade and drapery pairing can be measured, made, and hung before the holidays.

In that same DOE work, insulating cellular shades saved up to 20 percent of heating energy, and up to 15 percent of combined heating and cooling energy, against the same home with no shades at all. Those are best-case numbers. What you actually get depends on two choices: what hangs closest to the glass, and whether anyone lowers it at night.

Read each wall before you pick a fabric

Start with orientation. North glass loses heat all day and never pays it back. South and west glass collect real warmth on clear winter afternoons, and you want that sun in the room until it drops. East glass mostly matters at breakfast.

So the same house usually needs different answers on different sides. We'd put the heaviest insulating layer on north-facing rooms and bedrooms first, then on any tall glass beside seating, where cold reads as a draft on your shoulder even when the thermostat says the room is warm.

Write down which openings face which way before a workroom comes to measure. It changes the order sheet.

Put the insulating layer against the glass

The working layer sits closest to the window. For winter, that's a cellular (honeycomb) shade, mounted inside the frame where the opening allows it, because it traps air in its cells and in the pocket between shade and glass. The DOE fact sheet credits cellular shades with reducing nighttime heat loss and the cold drafts that collect near windows, and it says Lawrence Berkeley National Laboratory simulations found cellular coverings saved more energy than every other type of shading device.

Fit is the whole game here. A shade with wide side gaps leaks the very air it's supposed to hold, so ask for tight inside-mount tolerances, and on tall glass ask about side channels that close the edges.

Look for the Attachments Energy Rating Council label. AERC is the independent rating body the DOE fact sheet points buyers to, and its ratings score a product separately for warm and cool climates, so you can compare two honeycomb shades on more than color.

In street-facing rooms we'd take the top-down, bottom-up version every time. You keep the sky and the privacy at once.

Operation decides the savings

This is the part most window plans skip.

Pacific Northwest National Laboratory tested high-efficiency cellular shades in matched lab homes for DOE and the Northwest Energy Efficiency Alliance (report PNNL-27663, August 2018). When the shades were used the way people typically use them in winter, some up and some down all day, the average heating-season savings were insignificant compared with having no shades at all. The savings showed up when the big south- and west-facing shades were actually worked: up during the day, down at night. PNNL also found that seasonal schedules delivered consistent savings whether a person ran them by hand or an automated system did.

Our read: in a large house, nobody walks every window at sunset. Automate the rooms with the most glass and let the schedule do the remembering.

Designers are already there. Lutron's Luxury Residential 2026 Trend Report, based on Harris Poll surveys of high-net-worth homeowners and residential designers, found that 56 percent of designers now include automated shades in final designs and another 43 percent recommend them, while 38 percent of affluent homeowners said they're interested in adding them.

Power is the practical question. A 2019 DOE Better Buildings Residential Network session on window attachments laid out the options plainly. Hardwired motors give the cleanest result but are best planned during construction, since opening finished walls gets costly. Battery packs install easily in an existing house but need replacing, and they don't suit every large shade. Plug-in motors handle bigger windows but need an outlet near the window and a plan to hide the cord, usually behind drapery or inside a valance or shade pocket. For a fall retrofit, we'd use battery motors on standard windows and bring plug-in or hardwired power to the oversized ones. If the house already runs a control system, tie the shades into it; our guide to smart home features luxury buyers expect covers how that layer should behave.

Let drapery do the warm work in the room

Shades handle the glass. Drapery handles how the room feels.

For winter we'd hang full-height panels on a ceiling-mounted track, wider than the opening so the stack clears the glass when it's open. Interior designer Marie Flanigan, in Good Housekeeping's 2026 window treatment trends roundup, recommends drapery that runs from ceiling to floor and extends beyond the window, and she's right. A panel hung from the ceiling also leaves less of a gap at the top for warm room air to slip behind it.

Line everything that faces a cold wall. An interlining (the soft flannel layer a workroom sews between the face fabric and the lining) gives a drape real weight and a fuller fold, and it's the upgrade we'd pick before a more expensive face fabric. In bedrooms, pair a blackout shade with an interlined drape on a double track, and add a sheer on the front track for daytime if the view deserves it.

The silhouette is up to you, and 2026 gives you good options. In the same Good Housekeeping piece, Carrie Moore makes the case for ripple fold drapery on slim tracks that disappear into the ceiling. Diane Luna champions pinch pleats and warns that pleated panels ordered in a single fabric width come out skimpy, so order double widths. She also says not to go shorter than 18 inches on a valance. Flanigan likes drapery matched closely to the wall color for a fully drenched room. Lutron's report adds that 98 percent of designers say clients ask for custom shade fabrics, with natural fibers and rich textures leading.

Color is the easy win for fall. Wool or heavy linen in a deep shade from the new fall palette for luxury homes looks warmer at night than any white.

Room by room, the order we'd spend in

Primary bedroom first. Blackout cellular shade, interlined drapery, and a motor on whichever layer you'd otherwise forget. Bedrooms are where people feel cold glass most.

Then the living room with the biggest glass wall: an insulating shade on a schedule, plus ripple fold drapery in wool or a heavy linen blend that you can close on the worst nights.

Dining rooms come next if you host through the holidays. Lined panels soften the room's sound and make candlelight read richer against dark glass; we covered the rest of that room in holiday-ready dining rooms for luxury homes.

Rooms with art, rugs, or collection pieces need sun control as much as warmth. Put those shades on the same schedule so a bright south afternoon doesn't sit on a painting for hours.

Guest rooms and secondary spaces can wait for a second round.

Before the workroom measures

• Map every opening by orientation and mark which ones sit beside seating or beds.
• Decide the shade for each room first, then the drapery; the shade's mount depth affects where the track goes.
• Confirm motor power for each window: battery, plug-in, or hardwired.
• Ask for the AERC rating on any cellular shade you're quoted.
• Order pleated or ripple fold panels with enough fullness, and ask the workroom for its holiday cutoff date.
• Set the schedule on day one: insulating shades down at sunset, south and west shades up once the sun is on the glass.

Custom workrooms fill up as the holidays get closer, so the measure appointment is the thing to book this week. Bring the orientation map with you, and the right fabric ends up on the right window the first time.
