Winter can be expensive and uncomfortable if your home needs to be warmer. Your heater has to work harder to keep your home warm, but if your windows aren’t properly insulated, they can lose a lot of heat. This means cold air can come in and warm air can escape. While adding curtains and drapes can help a little, properly insulating your windows is the only best way to keep your room warm. So, to keep your living spaces warm, I’m sharing the 12 most effective tips for How To Insulate Windows for Winter.
Top 12 Methods To Insulate Windows
Insulating your windows is an easy and affordable way to stay warm and save money on your energy bill. Replacing single-pane windows with double-pane ones can help a lot, but not everyone can afford it.
That’s why insulating your current windows can make a big difference. Here are some helpful methods that I’ve used in my own home to keep my living spaces warm.
1. Caulk The Edges
Caulking the edges of your windows and doors is the first and easiest way to keep your room warm in winter. This method is simple and affordable. I started by removing the old sealant with a razor blade scraper and cleaning the area around the window edges. Then, I ran my hand along the edges to find any gaps. I used a caulking gun to apply a good-quality sealant where I felt cold air coming in. Finally, I used a wooden stick to smooth out the sealant.
This way, you can easily block drafts from your windows and doors. If the joints are over 5 years old, they may get damaged or worn out. Fix them with a high-quality sealant to keep the cold air out and your room warm during winter.
2. Apply Window Films
Window film is an easy and affordable way to insulate your windows, keeping warm air inside and cold air out. It’s a thick plastic wrap that sticks to the inside of the window frame and helps reflect some of the heat back into the room.
Window films are available at most hardware stores in different styles, like frosted or tinted. I bought some films based on my window measurements. To install the film, I cleaned the windows and cut the film to fit according to my window size. Then, I used glue to stick it to the window and used a hair dryer to smooth it out.
This is a long-lasting insulation solution that requires no maintenance. It’s great for old single-glazed windows or if you can’t replace them. The window film doesn’t block sunlight or change the appearance of your windows. It’s especially helpful for old windows that aren’t well-insulated and are easy to install.
3. Weather Sealing Strips
Another affordable way to insulate windows is by applying weather-sealing strips to prevent warm air from escaping through gaps. These thin strips seal the space between your window and the frame. You can easily find weather-sealing strips at local hardware stores, made from materials like foam, rubber, or vinyl.
To install them, remove the old sealant from the window sash using a putty knife and clean the area around the window. Then, cut the strip to the right size, peel off the backing, and stick it to the window frame. You can also use adhesive tape to keep them in place.
This simple DIY method is easy and effective and can also be used on doors. The strips are usually placed at the bottom of windows but can be used around the entire window. Just remember to remove them if you want to open your windows in the summer.
4. Draft Blocker
A simple and easy way to block cold air from coming in through windows or doors is by making a draft blocker. These are placed at the bottom of doors or windows. You can easily make one at home by filling fabric tubes with materials like old clothes, towels, or rice.
5. Cellular Shades
Most people know about regular blinds, but when it comes to insulating windows for winter, cellular shades can be very helpful. Instead of slats, they have a honeycomb design that is perfect to block light even from the top and sides of the window.
If you’re on a small budget, this is a good and affordable way to insulate your windows. I have cellular shades in some of my rooms, and they really work well for insulation. They’re definitely worth the price.
6. Bubble Wrapping
Another cheap way to insulate windows is by using bubble wrap. You may have seen bubble wrap in the packaging. It helps keep your home warm by trapping warm air inside the bubbles and keeping cold air out.
To install it, simply buy a roll of bubble wrap from a store. Spray some water on the window and press the bubble wrap against it, covering the whole window with no gaps. You can also use double-sided tape to hold it in place.
Bubble wrap adds an extra layer of insulation to keep your room warm. I used it in my attic and utility room because looks don’t matter in those areas. For the best results, choose bubble wrap with bigger bubbles.
7. Foam Tape
Self-adhesive foam tape is a quick and affordable way to insulate windows. It can seal gaps in warped window frames and is very easy to use. Just measure the gap, cut the tape to the right size, and stick it in place to keep the cold air out.
8. Thermal Curtains
If you’re replacing your old curtains and want to improve your window insulation, consider thermal curtains. They can be expensive, but they’re great at keeping your home warm and blocking out noise. These curtains are made from heavy fabrics like wool or velvet.
Thermal curtains come in many styles and colors to match your home design. They often have a special lining that keeps cold air out and warm air in.
If you can’t afford new curtains, try this easy trick: Hang a sheet or blanket over the curtain rod, letting it hang down over your curtains. This adds an extra layer of insulation to keep your home warm.
9. Secondary Glazing
If you have the budget and want a permanent solution to insulate your windows, consider secondary glazing. This adds a gap between your old window and a new glass layer, which helps reduce heat loss and block out noise.
You can buy custom-made frames with glass or use DIY kits. If you prefer custom frames, you can add a slim glass panel inside your windows. DIY magnetic kits use a clear plastic sheet that attaches to your window frame with magnets. You can use this on both windows and doors. To install, clean the surface, peel off the backing, and stick on the magnetic tape. The magnets will hold the sheet in place, creating a tight seal around your window to keep heat from escaping.
10. Solid Shutters
Solid shutters are becoming more popular and are a great way to insulate windows by reducing heat loss. They are attractive, practical, and versatile. You can easily find them at local interior design stores.
11. Double Or Triple Glazing
Double or triple glazing is a type of window with two or three layers of glass. A special gas is trapped between the panes to keep warm air inside. The extra layers of glass and gas make these windows very good at insulating. While they can be expensive, they are much more energy-efficient than single-glazed windows.
12. Blind and Curtain Combinations
Layering blinds with curtains can help reduce heat loss and keep cold air out. Simply hang curtains in front of your blinds on the windows. This will help keep your home warmer and also improve the look of your space.
