How to Use Bubble Wrap on Windows to Keep Your Home Warm This Winter
When the temperature drops, one of the biggest sources of heat loss in your home is through the windows. You might think you need expensive insulation or double glazing, but there’s a simple and affordable hack that works surprisingly well — using bubble wrap.
Bubble wrap acts as a lightweight, transparent insulation layer that helps trap warm air inside while blocking out the cold. It’s a quick DIY solution many households in cold climates use to reduce heating costs.
How It Works
The air bubbles in the wrap create a barrier that slows down heat transfer. The trapped air acts as insulation — similar to how double-glazed windows work — keeping the warmth in and the chill out.
How to Apply Bubble Wrap to Windows
Cut the wrap to size:
Measure your window and cut the bubble wrap slightly larger than the glass area.
Lightly mist the window with water:
Use a spray bottle to apply a fine layer of water directly onto the glass.
Press the bubble side against the glass:
The water helps the wrap stick naturally — no tape needed. Make sure the bubbles face toward the glass.
Seal the edges (optional):
For extra insulation, you can use clear tape around the edges, especially if you live in a very cold area.
Remove when the weather warms up:
The wrap can be easily peeled off without leaving residue, and you can reuse it next winter.
Extra Tips:
For best results, apply it to windows you don’t open often (like in living rooms or bedrooms).
The more layers of bubble wrap you use, the stronger the insulation — but even one layer can make a noticeable difference.
You can also use this trick on greenhouse or basement windows to reduce heat loss.
With just a few minutes and a roll of bubble wrap, you can make your home warmer, cozier, and more energy-efficient — no tools or expensive materials required.
How to Stick Bubble Wrap to Windows Without Using Water
If you don’t want to spray water on your windows — maybe because they’re hard to reach or you’d rather avoid streaks — there are several easy ways to attach bubble wrap that work just as well.
1. Use Double-Sided Tape
This is the simplest and most effective method.
Apply strips of double-sided tape around the window frame.
Press the bubble wrap edges firmly onto the tape, with the bubble side facing the glass.
It holds securely and can be removed later without leaving marks if you use removable adhesive tape.
Tip: Choose tape labeled “removable” or “for glass surfaces” to avoid sticky residue.
2. Use Repositionable Adhesive Spray
A light, temporary adhesive spray (often used in crafts) works perfectly for this.
Spray a thin layer onto the flat side of the bubble wrap.
Wait about 15–20 seconds for it to become tacky.
Then press it directly onto the window.
It sticks well but peels off easily when winter is over — leaving no residue.
3. Secure with Masking Tape Around the Edges
If you only need short-term insulation, simply hold the bubble wrap in place and tape around the edges with masking tape.
It’s gentle on glass and comes off cleanly.
4. Use a Removable Frame
For a more permanent seasonal setup, create a light wooden or plastic frame that fits your window.
Attach the bubble wrap to the frame, then press or hook the frame into the window opening each winter.
This method looks neat, reusable, and avoids adhesives altogether.
Extra Tip:
Always keep the bubble side facing the window glass, since the air pockets act as the insulating layer. And make sure the glass is clean and dry before applying — this prevents moisture buildup or mold.
With these easy methods, you can enjoy the warmth of bubble wrap insulation — no water required.
