Drafty Windows? Why Heavy Draperies Still Work in Old New England Homes

If you own an older home in Portland, Brunswick, Augusta, or anywhere along the coast, you probably love its character: the tall windows, the original trim, the creaky charm. You probably also know the downside. On a windy January night, you can feel the cold from across the room.

Replacing historic windows can be costly, and in some homes it isn’t what you want to do at all. The good news is that a classic solution still works. Heavy, well-made draperies have been keeping New England homes warmer for generations, and they’re making a comeback for good reasons.

Why Old Windows Are Drafty

Older windows tend to lose heat in a few ways:

Single-pane glass has very little insulating value, so the glass itself gets cold.
Aging frames and sashes can leave small gaps where air leaks in.
Worn weatherstripping or glazing lets drafts sneak around the edges.
Tall, large openings mean more glass area, and more area to lose heat through.

When the glass is cold, the air next to it cools, sinks, and spills across your floor. That’s the chill around your ankles, even when the thermostat says the room should be comfortable.

How Draperies Help

Draperies don’t turn an old window into a new one, but they add something it lacks: a thick layer of fabric and trapped air between you and the cold. Here’s how they help:

They slow heat loss. A heavy or lined fabric adds an insulating layer, and the air pocket between the drapery and the glass acts as a buffer.
They block the cold-air spill. Floor-length panels that hang close to the wall can keep cold air from sinking into the room.
They make the room feel warmer. You’re no longer sitting next to a cold surface radiating chill, which is a big part of comfort.
They cut down on noise and glare, which is a nice bonus for street-facing rooms.

What Makes a Drapery Good at Insulating

Not every curtain performs the same. If warmth is your goal, look for these features:

Thick, tightly woven fabric. Heavier materials like wool blends, velvet, and dense cotton or linen blends hold heat better than thin sheers.
Lining. A lined drapery is noticeably more effective than an unlined one. Thermal or blackout linings add even more.
Full width. Panels cut generously, with plenty of fullness, cover the window better than skimpy ones.
The right length. Panels that reach the floor or just skim it stop air from flowing underneath.
Close-fitting hardware. Rods mounted wide and high, with panels that overlap the window frame on all sides, help seal the edges.

Pair Them With Shades for Even Better Results

For the draftiest rooms, layering is the answer. Combine custom draperies with cellular shades inside the window frame. The shade adds an insulating layer close to the glass, and the drapery adds a second one in front of it.

This approach also gives you flexibility. During the day you can open the draperies and leave the shade partly lowered for light and privacy. At night, you close everything for maximum warmth.

If you’d rather not think about it, motorized options can be scheduled to close at sunset and open in the morning.

Draperies That Respect Your Home’s Character

One reason people hesitate about window treatments in older homes is worry about style. They don’t want something that fights with historic woodwork or traditional proportions. That’s where custom work pays off:

Fabrics, colors, and patterns can be chosen to suit your decor, from classic to contemporary.
Heights and fullness can be tailored to your ceilings and window shapes, which in older homes are rarely standard.
Hardware can be selected to complement your trim and finishes.
Tall or unusual windows can be measured and fitted precisely, rather than forced into off-the-shelf sizes.

If you also want to keep historic wood trim visible, wood-toned shutters are another classic option that suits many older homes.

Combine Window Treatments With Basic Weatherproofing

Window treatments work best alongside simple draft fixes. Check for gaps around frames, replace cracked caulk, and renew worn weatherstripping. The U.S. Department of Energy has good guidance for homeowners on sealing air leaks. Efficiency Maine is also worth a look for current programs available in our state.

Don’t Forget Safety and Maintenance

Keep drapery panels away from space heaters and baseboard heaters.
Vacuum or dust them regularly with a soft brush attachment.
Check cleaning instructions before choosing a fabric. Some are dry-clean only.
Keep cords out of reach if you have young children. Learn more about our child safety services.
