Airtight Window Plastic: Preventing Billowing

how to keep window plastic from billowing

Plastic window film is a common method used to reduce drafts and energy waste. The plastic is cut to fit the window and applied using double-sided tape or adhesive, and then shrunk with a hair dryer to fit tightly over the window. While this method can be effective at reducing drafts and condensation, it does not address the underlying issue of heat loss or gain, and may not significantly impact energy bills. Additionally, the plastic may billow or bulge inward due to pressure differentials, which can be caused by wind or convection currents within the home. To prevent this, some people use a blow dryer to reduce the plastic whipping in the wind.

Ensure windows are shut, locked, and properly sealed

To keep window plastic from billowing, it is essential to ensure that your windows are shut, locked, and properly sealed. This step is crucial in creating an effective barrier against cold air and maintaining a comfortable indoor temperature.

Start by checking that all windows are completely shut. This may seem obvious, but it is a fundamental step that should not be overlooked. Go around your home and carefully close any windows that might be slightly ajar. Pay attention to those windows that are harder to reach or are located in less frequently used areas of your home.

Next, make sure the windows are locked. Locking mechanisms are designed to provide a tighter seal, reducing gaps that allow cold air to enter and warm air to escape. Locked windows also prevent accidental opening, which could undo your efforts to create a sealed environment.

Proper sealing is critical to the process. Check for any gaps or cracks around the window frames. These openings can be sealed with caulk or spray foam, which will help create a continuous barrier against the elements. If you're handy, you can do this yourself, but if you're unsure, it's best to consult a professional.

Another important consideration is the quality of your windows. Older windows, especially those that are 15 years or older, may not have the same insulating properties as modern windows. They may lack features such as Low-E film or argon gas between double panes, which are designed to improve insulation and reduce heat transfer. If your windows are outdated, consider investing in energy-efficient replacements.

Finally, remember that while ensuring windows are shut, locked, and properly sealed is essential, it is only one aspect of creating an energy-efficient home. For a comprehensive solution, consider a whole-home approach that includes professional air sealing and upgraded insulation. This might involve seeking advice from experts who can identify and address the specific needs of your home.

Use a blow dryer to reduce billowing

Using a blow dryer is an effective way to reduce window plastic billowing. It is a simple and temporary solution to removing condensation from windows.

Firstly, ensure the window is clean and dry. Remove any condensation from the windows before applying the plastic, otherwise, you will seal the moisture between the glass and the plastic. Move any curtains or blinds out of the way and ensure you have easy access to an electrical outlet.

Next, plug in your blow dryer and set it to a high heat setting. If your blow dryer has a nozzle attachment, use it to concentrate the heat. Direct the blow dryer at the edges of the window where the seal is, and slowly move the dryer around the perimeter of the window.

The blow dryer will help to reduce the plastic from billowing in the wind when strong drafts come through. It is also useful for applying the plastic, as the heat will cause the plastic to shrink and tighten. This method can also be used to defog mirrors and remove wax or crayon stains from surfaces.

However, it is important to note that using a blow dryer is only a temporary fix, and it does not address the underlying issues of high humidity or poor insulation. For a longer-term solution, consider improving the insulation value of your windows or investing in a dehumidifier to remove moisture from the air.

Cut the plastic to fit your window

If you're looking to cut plastic to fit your window, it's likely that you're trying to reduce drafts and energy waste. This is a common tactic, and while it may not solve the underlying problem causing heat loss, it is inexpensive and perfect for a DIY project.

Before cutting the plastic, it's important to clean the window frame. You should also measure the window to ensure you cut the plastic to the right size. Leave a few inches on either side, as this extra plastic will be used to adhere the plastic to the window frame.

When cutting the plastic, it's important to be as precise as possible. You don't want to cut it too small, as this will create gaps that defeat the purpose of the plastic covering. It's better to cut it slightly larger, as you can always trim the excess later.

Once you've cut the plastic to the desired size, you're ready to apply it to the window. Use double-sided tape to adhere the plastic to the window frame, starting at the top and working your way down. Smooth out any bubbles or wrinkles as you go.

After the plastic is securely taped to the window frame, use a hair dryer to shrink-wrap the plastic and ensure a snug fit. This will help reduce the billowing effect and create a tighter seal.

Use double-sided tape to adhere the plastic

Using double-sided tape to adhere plastic over windows is a common tactic to reduce drafts and energy waste. It is an inexpensive and simple DIY project that can be done by purchasing a window insulation kit from a hardware store.

To start, cut the plastic film to fit your window, leaving a few extra inches on either side. Clean the window frame thoroughly before applying the double-sided tape. Then, attach the plastic sheet to the window frame using the tape, making sure it is secure and adheres to the tape. Once the plastic is attached, use a hair dryer to shrink-wrap the plastic film so that it fits snugly across the window.

While this method can help reduce drafts and heat loss, it may not completely solve the underlying problem of heat loss or gain around your windows. It is important to note that the plastic film may not always lie flat and can billow or bulge due to atmospheric pressure changes or wind. Additionally, it may not significantly impact your energy bills, and the plastic may need to be removed during the warmer months to take advantage of natural cooling.

Overall, using double-sided tape to adhere plastic over windows can be a temporary solution to improve insulation, but it may not be a long-term fix for drafty windows. For a more permanent solution, consider replacing your windows or seeking professional advice for whole-home insulation upgrades.

Remove the plastic during summer months

Window plastic is a great way to keep your home warm during the winter months. However, it is recommended to remove the plastic during the summer months.

The plastic film acts as an extra layer of insulation, helping to keep the warmth inside your home. This is particularly useful in colder climates, where the temperature difference between the inside and outside of your home can be significant. During the summer, however, the temperature dynamic changes. The sun's heat energy is absorbed by the plastic film, which can lead to a build-up of heat inside your home, similar to a greenhouse effect. This can make your home uncomfortably warm and stuffy, increasing your energy costs as you may need to use more air conditioning to compensate.

Removing the plastic film during the summer months allows you to take advantage of natural cooling strategies, such as cross-ventilation. Opening windows on opposite sides of a room creates a natural draft, circulating air and cooling down the space. The plastic film can disrupt this airflow, even when windows are slightly open, making it harder to keep your home cool.

Additionally, condensation can form on plastic-covered windows during the summer due to the temperature difference between the warm indoor air and the cooler outdoor temperature. This moisture can become trapped between the plastic and the glass, leading to potential issues such as mould and mildew growth and damage to window frames.

By removing the plastic film, you can improve airflow, reduce the risk of condensation, and utilise natural cooling methods to keep your home comfortable during the warmer months.

Remember to properly size the film before removing it, leaving a few inches on either side. Clean the window frame and gently pull the tape off without damaging the finish.

Frequently asked questions

Clean the window frame and ensure it is properly sized, leaving a few inches on either side.

Use a hairdryer to reduce the plastic whipping in the wind when strong drafts come through.

The space between the window and the plastic film forms a pocket that traps air. When the wind blows outside, it "inflates" this pocket and causes it to bulge inward.

You can use light-blocking and energy-saving curtains and blinds.

Plastic film is inexpensive, reduces drafts, helps the house feel warmer during winter, and reduces moisture buildup on the window.
