One way to do this is by using plastic window insulation film, which can help block drafts and keep your space warmer in winter. This option is inexpensive, easy to install, and can be done yourself without the need for special tools or a professional installer. However, it is important to note that this is only a temporary solution, and if you find yourself using it every year, there may be underlying issues with your windows that need to be addressed. In this article, we will discuss the pros and cons of using plastic window insulation and provide step-by-step instructions on how to install it correctly.

What You'll Learn
Using plastic film to seal windows
Step 1: Prepare the Window
Start by cleaning the window and its surrounding frame. Use a knife to scrape off any old caulk or peeling paint. Then, wipe the window surface with a cloth and some rubbing alcohol to ensure it is completely dry and free of debris.
Step 2: Apply Tape
Apply double-sided adhesive tape to the window frame. Attach the tape to the sides and bottom of the window, pressing it firmly into place. You can use regular adhesive tape, but be aware that it may damage paint or varnish when removed. Alternatively, use magnetic tape if you want to open your windows for fresh air occasionally.
Step 3: Attach Plastic Film
Leaving a small excess of around 1-2 inches, cut the plastic film to fit the window measurements. Start in one top corner, and roll the plastic film down, adhering it to the tape. Some kits come with pre-taped film, making this step easier. Ensure the film is smooth and free of wrinkles, and be careful not to leave any gaps.
Step 4: Secure and Trim
Once the plastic film is in place, use a hairdryer to secure it further. Applying heat will shrink the plastic, ensuring a tight and wrinkle-free fit. Finally, trim any excess plastic for a neat finish.
Additional Tips:
- Consider using thicker plastic for larger windows or multiple layers of film for extra insulation.
- You can also use bubble wrap with packing tape, or even aluminium foil, for a cheaper alternative.
- Combine with thermal curtains for maximum insulation.
- Re-apply caulk around the window frame if necessary to seal any leaks.

Applying heat-shrink plastic
Step 1: Prepare the Window
Before applying the heat-shrink plastic, ensure that the window surface is clean and completely dry. Use a knife to scrape off any old caulk or peeling paint from the window edges. Wipe the surface with a clean cloth and, if needed, use rubbing alcohol to remove any stubborn residue or grease.
Step 2: Measure and Cut the Plastic
Measure the size of your window, including the frame. Cut the heat-shrink plastic sheet to size, leaving an extra buffer of around 1 inch (2-5 inches, according to some sources) on all sides. This extra plastic will ensure complete coverage and help create a tight seal.
Step 3: Apply Adhesive
Use double-sided adhesive tape along the sides and bottom of the window frame. Firmly press the tape into place, ensuring a strong bond. Do not remove the liner from the tape just yet.
Step 4: Attach the Plastic Sheet
Start at the top left corner of the window and roll out the plastic sheet towards the top edge of the window frame. Cut the plastic sheet to size, leaving an overhang on both the left and right sides as previously measured. Now, remove the liner from the tape and gently press the plastic sheet onto the tape, smoothing out any wrinkles or bubbles as you go.
Step 5: Shrink the Plastic
Use a hairdryer or blow dryer on the plastic sheet to shrink and tighten it. Apply heat evenly across the surface, moving the dryer back and forth. This step will help create a taut, clear, and almost invisible layer of insulation.
By following these steps, you can effectively apply heat-shrink plastic to your windows, helping to keep the warmth in and the cold out during winter. Remember to remove the plastic and tape when the cold season is over, and consider using thermal curtains or blinds for added insulation and comfort.

Using bubble wrap
Bubble wrap is a cheap and effective way to insulate windows for winter. It is a great option for those who cannot afford to upgrade their windows or invest in double glazing. Bubble wrap can be bought cheaply, or even obtained for free, and it can make a big difference in preventing heat from escaping through windows.
To insulate your windows with bubble wrap, you will need bubble wrap with large bubbles, a roll of packing tape, and a water spray bottle. Start by cleaning the window with an anti-bacterial surface cleaner. Then, cut the bubble wrap to the size of the window, ensuring the bubbles are facing inward. Spray water onto the window, and stick the bubble wrap onto the glass. Use the tape to secure the bubble wrap around the edges of the window frame.
Some people prefer to use tape to attach the bubble wrap to the window, rather than water. If you choose this method, start by taping the bubble wrap to the window frame, before using a hairdryer to shrink the plastic and create a taut finish.
Bubble wrap can also be used in conjunction with other insulating methods. For example, you can use it with plastic sheeting, or with window insulation kits. Window insulation kits are a good option for those who want a seamless finish, as the plastic film is applied to the window with double-sided tape, and then cut to size.

Caulking windows
Before you start caulking windows, pre-application check-ups are essential to ensure that the process goes smoothly. First, you need to locate any areas on your windows with air leakage. You can do this by feeling around the window frame's edges or by lighting a candle and moving the flame around the window frame edges. The flame wavering means there's moving air, indicating it needs caulking. After locating the air drafts, you must clean the window surfaces to make sure that the caulk will adhere properly. Use a scrub brush and warm soapy water to clean the surface of any remaining dirt.
You can buy caulk as either a squeeze tube or cartridge. It is recommended to use a cartridge and caulking gun so you can apply an even bead around the perimeter of your windows. Silicone caulk is long-lasting and effectively fills in gaps that are leaking cold air into your home. The surface needs to be clean and dry for caulk to adhere properly. In the winter, you may have ice around your windows that will need to be melted and dried before you start. Otherwise, the ice will form a barrier between the caulk and the window. You can use a hair dryer to melt the ice. Any old caulk or peeling paint will also need to be carefully removed with a putty knife.
Apply a continuous bead of caulk around the outside borders of your window. You can also apply caulk between the window frame and siding. Allow the caulk to dry and cure overnight. Repeat as needed on more windows.
In addition to caulking, you can also use plastic sheeting over your windows to keep heat in and lower your heating bill. You can use bubble wrap, or a window insulation kit, which is a more affordable way to insulate multiple windows.

Using magnetic tape
Plastic window insulation is a cost-effective way to prevent heat loss during the winter. One way to install plastic sheeting over your windows is by using magnetic tape.
Before you begin, it is important to clean the window area with a damp cloth and allow it to dry completely. You should also check the caulk seal that borders your window on the outside and inside.
To install the plastic window insulation, start by cutting the magnetic tape according to your window dimensions. Then, peel off the adhesive backing and stick the tape to the window frame. Be sure to cover any gaps or leaky spots.
Next, cut the plastic sheeting to size, leaving a generous margin for error. You can always trim the excess later. Position the plastic sheet over the window, aligning it with the magnetic tape. Press the sheet firmly onto the tape, ensuring that there are no gaps.

You can use a window insulation kit, which typically includes double-sided tape and plastic film. Alternatively, you can use plastic sheeting, bubble wrap, and tape.
First, apply the double-sided tape to the perimeter of the window, leaving a few inches on either side. Then, cut a slightly oversized piece of plastic film and adhere it to the tape, starting at the top and bottom, then the sides. Finally, use a hair dryer to shrink the plastic for a smooth, wrinkle-free finish.
Plastic window insulation is only a temporary solution and may not be aesthetically pleasing. Additionally, removing the tape at the end of the season can damage paint or varnish, and the disposable nature of this method may be less environmentally friendly than a more permanent fix.
