Drafty Windows Start With Thermal Lined Curtains

Heavy thermal lined curtains are the easiest place to begin, and they look lovely too. A thick lining traps a layer of still air between the fabric and the cold glass, so less heat slips out at night. Choose curtains that reach the sill or floor and are a little wider than the window. Home sites like Hometalk are sharing first freeze fixes right now, and curtains are always near the top. It feels like wrapping your window in a warm blanket. Start with the window where you feel the chill the most..

You will need: Thermal lined curtains or a plain thermal liner, a curtain rod, tie backs.

How to make it: 1. Measure the window and add a few inches on each side. 2. Hang the rod and slide on the lined curtains so they reach the sill or floor. 3. Close them at sunset and open them again in the morning sun.

Clear Shrink Film Seals the Whole Window

Window insulation film is the trick that surprises people the most. You stick double sided tape around the frame, press a thin clear plastic sheet over it, then warm it with a hair dryer until it pulls tight like a drum. The film creates a still air pocket that blocks drafts on even the oldest drafty windows, yet you can still see right through it. It costs only a few dollars per window and peels off in spring. Searches for window film for winter are climbing fast right now. Have you ever tried it on your coldest room?

You will need: A window insulation film kit, double sided tape, scissors, a hair dryer.

How to make it: 1. Clean and dry the frame, then run the tape all the way around it. 2. Press the film onto the tape, leaving a little extra on every side. 3. Warm the film with a hair dryer until the wrinkles vanish, then trim the edges.

Bubble Wrap on the Glass Really Works

This one sounds silly, but greenhouse growers have used it for years. Spray a light mist of water on the glass, then press a sheet of bubble wrap on with the bubble side facing the window. The water holds it in place, and the bubbles act like tiny pockets of insulation for drafty windows. Light still comes through softly, which makes it perfect for a bathroom, basement or spare room where you do not need a clear view. When spring comes, just peel it off and let the glass dry. Would you try it on a window nobody sees?

You will need: Bubble wrap with large bubbles, a spray bottle of water, scissors.

How to make it: 1. Cut the bubble wrap to fit each pane of glass. 2. Mist the glass lightly with water. 3. Press the bubble side onto the glass and smooth it from the center out.

Drafty Windows Love Foam Weather Stripping

If your window rattles or you can see daylight around the edges, foam weather stripping is your new best friend. It comes on a roll with a sticky back and squishes into the gap when the window closes, so cold air has nowhere to sneak through. It works on most wood and vinyl frames and costs about the price of a coffee. Measure twice, cut once and press firmly. Many people say their drafty windows also get much quieter on windy nights. Which window will you test it on first?

You will need: Self adhesive foam weather stripping, a ruler, scissors, rubbing alcohol and a cloth.

How to make it: 1. Wipe the frame clean with a little rubbing alcohol and let it dry. 2. Cut strips to length and peel the backing a little at a time. 3. Press the foam where the sash closes, then shut the window to set it.

Rope Caulk Fills Gaps in Seconds

Rope caulk is soft, gray and feels a lot like modeling clay for grown ups. You simply pull a strand off the coil and press it into gaps around the glass or where the window meets the frame. It stays soft all winter and pulls out cleanly in spring without hurting the paint, which makes it a great choice for renters. Kids can even help press it into place with their fingers. It is one of the cheapest fixes for drafty windows on this whole list. Do you have an old window with little gaps you can feel?

You will need: A coil of rope caulk, a dry cloth.

How to make it: 1. Wipe the gap so it is clean and dry. 2. Pull off a strand and press it firmly into the crack with your thumb. 3. Smooth it flat, then peel it away when warm weather returns.

Hang the Curtain Rod Wide and High

Here is a designer trick that also keeps you warmer. Mount your curtain rod a few inches above the frame and well past both sides of the window. When the curtains close, they cover the whole frame instead of leaving cold gaps at the edges. Your window also looks bigger and the ceiling feels taller. For extra warmth, choose a wraparound rod that curves back to the wall so air cannot slip around the sides. It is a small change with a big cozy payoff. Will you move your rods this weekend?

You will need: A longer curtain rod or a wraparound rod, brackets and screws, a drill, a pencil, a level.

How to make it: 1. Mark bracket spots about four inches above and six inches past each side of the frame. 2. Ask an adult to drill and fix the brackets using a level. 3. Hang the rod and curtains so they cover the full frame when closed.

Clear Magnetic Inserts Act Like a Second Pane

If you love the idea of double pane windows but not the price, try a clear interior insert. A thin acrylic sheet sits inside the frame and holds on with a slim magnetic strip, so it pops on in fall and off in spring. It acts like an extra pane of glass, trapping still air and turning drafty windows into snug ones. Some people buy ready made kits, while handy folks have the acrylic cut at a hardware store and add magnetic tape. Either way, the view stays clear. Could this be the upgrade your living room needs?

You will need: A clear acrylic sheet cut to size, adhesive magnetic tape, adhesive steel strips, a measuring tape.

How to make it: 1. Measure the inside of the frame and have the acrylic cut slightly smaller. 2. Stick steel strips around the frame and magnetic tape around the acrylic edges. 3. Press the insert into place until the magnets grab.

Felt Strips Close the Sash Gap

Old double hung windows are classic drafty windows, and they often leak right where the top and bottom sashes meet in the middle. Thin felt strips fit that narrow gap perfectly and stay neat and almost invisible. Felt is soft, so the window still slides up and down without sticking. It also stops the little rattle you hear on windy nights. This is a quick fix you can finish in ten minutes, and it is gentle on old wood. Have you noticed a whistle from your window when the wind picks up?

You will need: Self adhesive felt weather strip, scissors, a dry cloth.

How to make it: 1. Lower the top sash slightly and wipe the meeting rail clean. 2. Cut the felt to length and press it along the rail. 3. Close the window and check that it still slides smoothly.

Find Drafty Windows With a Tissue Paper Test

Before you buy anything, find out where the cold air is really coming in. Tape a single sheet of tissue paper to a pencil and slowly move it around the edges of each window on a breezy day. If the tissue flutters, you found a leak. It is much safer than any flame trick, and kids love being the draft detectives. Mark each leak with a small piece of painter’s tape so you know exactly where your foam, felt or caulk should go. Who in your home would make the best draft detective?

You will need: Tissue paper, a pencil, clear tape, painter’s tape.

How to make it: 1. Tape one tissue sheet to the end of a pencil. 2. Move it slowly along every edge and corner of the window. 3. Mark any spot where the tissue moves and fix those spots first.

A Foam Board Insert for Unused Windows

Do you have a window in a guest room or storage room that nobody uses all winter? A snug foam board insert can block nearly all the cold from drafty windows you never open. Cut rigid foam board to fit inside the frame, wrap it in pretty fabric so it looks finished, and press it in. Felt along the edges helps it sit tight without scratching anything. On sunny days you can pop it out to let the light in, or leave it in during the coldest weeks. Which unused window in your home could use one?

You will need: Rigid foam insulation board, a craft knife, fabric, duct tape, felt strips.

How to make it: 1. Measure the inside of the frame and have an adult cut the foam board to fit snugly. 2. Wrap the board in fabric and tape it neatly on the back. 3. Add felt to the edges and press the insert into the window.

Caulk the Cracks Around the Trim

Sometimes the leak in drafty windows is not in the glass at all but in the cracks around the trim. Look for thin gaps where the trim meets the wall or the sill. A bead of caulk fills them and stops cold air from sneaking behind the wood. Clear removable caulk is great for renters because it peels away in spring, while paintable caulk is a lasting fix for owners. Go slowly, keep a damp cloth nearby and smooth the bead with a fingertip. Do you see any cracks around your window trim right now?

You will need: A tube of caulk, a caulk gun, painter’s tape, a damp cloth.

How to make it: 1. Clean the gap and run painter’s tape along both sides. 2. Squeeze a thin, steady bead of caulk into the crack. 3. Smooth it with a damp fingertip and pull the tape before it dries.

Let the Sun In by Day

Free heat shines on your house every sunny day, so let it in. Open the blinds and curtains on south facing windows in the morning and let the sun warm your floors and furniture. As soon as the sun goes down, close everything to hold that warmth inside. It costs nothing at all, and you can feel the difference in a sunny room by the afternoon. Your houseplants will love the extra light too. Which side of your home gets the most winter sun?

You will need: Blinds or curtains that open and close easily, a sunset reminder on your phone.

How to make it: 1. Find the south facing windows in your home. 2. Open blinds and curtains fully on sunny mornings. 3. Close them at sunset to trap the heat inside.

Frost on the Glass Is a Warning Sign

When frost or water drops form on the inside of the glass, your window is telling you something. Warm, moist air is hitting a very cold surface, which often means you have drafty windows that need extra insulation. Wipe the glass dry each morning so water does not soak into the sill and cause mold or peeling paint. Running the bathroom fan and the kitchen fan while cooking helps keep moisture down too. Then add film, a curtain or an insert to that window. Which window frosts up first in your home?

You will need: A microfiber cloth, a small towel for the sill, a mini squeegee.

How to make it: 1. Wipe the glass and sill dry every morning. 2. Run exhaust fans when cooking or showering. 3. Add film, curtains or an insert to the windows that frost the most.

Big Glass Doors Are Drafty Windows Too

A sliding glass door is basically a giant window, and it can lose a lot of heat. Check the bottom track for gaps and vacuum out the dirt so the door closes tightly. A strip of foam or brush weather seal along the edge where the door meets the frame helps a lot. At night, hang a long thermal curtain across the whole door and tuck in the edges. You can also lay a draft roll along the track when you are not using the door. Is your patio door the coldest spot in the house?

You will need: A vacuum, foam or brush weather seal, a long thermal curtain, a draft roll.

How to make it: 1. Vacuum and wipe the door track clean. 2. Add weather seal where the door meets the frame. 3. Close a long curtain over the door every night.

Finish Drafty Windows With a Cozy Sill Roll

For the final touch, lay a soft draft roll right on the sill where the bottom sash meets the frame. It catches the cold air that sinks down the glass and keeps it from rolling across the room. You can sew one from an old sweater sleeve or a long sock filled with rice or dried beans in a few minutes. Pick colors that match your room and it looks like decor.
