What You'll Learn

Cut the plastic bigger than the window opening
When covering windows with plastic, it is important to cut the plastic slightly larger than the window opening. This is a crucial step as it ensures a proper seal and allows for any excess plastic to be trimmed later. The recommended size is about a foot bigger in both dimensions, providing a generous margin for error. This excess plastic can be used to secure the plastic in place, creating a tighter seal and preventing air leakage.
The plastic film should be attached to the tape, leaving a slight overlap on all sides. This overlap will be trimmed later, but it is important to ensure that the plastic is smooth and taut across the window opening. One user recommends using a blow dryer to secure the plastic more firmly, shrinking and tightening the seal. This step is particularly important when using thin plastic films, which are commonly found in budget-friendly window shrink and seal kits.
While thin plastic is a popular choice for those on a budget, it is worth noting that it may not offer the same level of durability and insulation as thicker vinyl plastic. Thick vinyl, typically ranging from 6 to 8 mil in thickness, provides superior tear resistance and insulation properties. It is also reusable over multiple seasons, making it a cost-effective option in the long run. However, due to its increased thickness, thick vinyl may require a more robust solution for attachment, such as a storm window kit, rather than adhesive tape.
When attaching plastic to windows, it is essential to consider the potential for damage to the surrounding walls and trim. Common attachment methods, such as double-sided tape, can leave behind adhesive residues or even physical damage. This is especially concerning for renters or homeowners who wish to minimize damage to their property. To avoid this issue, consider using alternative solutions such as spring-tension curtain rods or bamboo rods to hold the plastic in place, creating a neat and damage-free installation.

Use tape to attach the plastic film
Covering your windows with plastic is a great way to winterize your home on a budget. It is a simple and effective method to reduce drafts and heat loss. When it comes to attaching the plastic film to your windows, one popular option is to use tape. Here is a step-by-step guide on how to do it:
Prepare the Plastic Film:
Before you begin, it is important to cut your plastic film slightly larger than the window you want to cover. This will ensure that you have enough material to work with and create a tight seal. Aim for about a foot of extra plastic on all sides, as you can always trim the excess later.
Clean the Window Frame:
Make sure the window frame is clean and free of any dust or debris. This will help the tape adhere better and create a stronger bond.
Apply the Tape:
Choose a tape that is suitable for your needs. Heat-shrink plastic kits usually come with double-sided tape, which can be a convenient option. You can also use common package-sealing tape, duct tape, or even staples. However, keep in mind that these options may leave stains or adhesive residues, so they might not be ideal if you are renting or concerned about potential damage.
Apply the tape around the edges of the window frame, creating a frame onto which you will attach the plastic film. Overlap the tape slightly onto the glass to ensure a tight seal.
Attach the Plastic Film:
Carefully unroll the plastic film and position it over the taped area. Smooth out any wrinkles or creases, ensuring the plastic is taught and flat. Press the plastic film onto the tape, creating a strong bond. Leave a slight overlap on all sides, as you will trim the excess later.
Shrink the Film:
Use a blow dryer on a warm setting to shrink and tighten the plastic film. This step helps to create a tighter seal and remove any remaining wrinkles.
Trim the Excess:
Once the plastic film is securely attached and shrunk, carefully trim away the excess plastic using a sharp blade or scissors. Take your time with this step to ensure a neat finish.
By following these steps, you can effectively use tape to attach plastic film to your windows, creating a cozy and energy-efficient environment during the colder months. Remember to choose a tape that suits your needs and always work carefully to ensure a strong and long-lasting seal.

Use a blow dryer to secure the plastic
Covering your windows with plastic is a great way to winterize your home on a budget. It is an easy DIY solution that can help reduce drafts and heat loss. While thin plastic is a more budget-friendly option, thick vinyl plastic provides superior insulation properties and long-lasting durability.
Once you have selected the type of plastic you want to use, you will need to cut it to size. Cut the plastic slightly bigger than the window you are covering, leaving a slip overlap on all sides. This will allow you to trim the excess plastic later if needed.
Now, we can get to the heart of your request: using a blow dryer to secure the plastic. After you have attached the plastic film to the tape, you can use a blow dryer to heat the plastic, which will help to shrink and tighten the seal. This step is especially important if you are using heat-shrink plastic. Start by turning on your blow dryer to a high setting and directing the airflow towards the plastic. Move the blow dryer back and forth, ensuring that you heat the plastic evenly. As the plastic heats up, you will notice it start to shrink and conform to the size of the window. This process will also help to remove any wrinkles or bubbles, creating a neater finish.
Using a blow dryer is a great way to secure the plastic without the need for tape, staples, or other more permanent solutions. It is essential to be careful when handling the blow dryer and to avoid touching the hot plastic immediately afterward. Once the plastic has cooled down, you can trim any excess plastic from the edges for a neat finish.

Trim excess film from edges
When trimming excess plastic film from the edges of your window, it is important to be careful and precise. Here is a step-by-step guide to help you through the process:
First, cut the plastic film to size, leaving a slight overlap on all sides. This excess plastic will be trimmed later. It is recommended to cut the plastic film about a foot bigger than the window opening in both dimensions to allow for a margin of error. This excess can be used to create a tighter seal by shrinking the film with a blow dryer, securing it more firmly in place.
Next, attach the plastic film to the window using tape, staples, or wooden battens and nails. If using tape, apply it to all edges of the window, creating a strong adhesive seal. For a more durable and robust solution, consider using thick vinyl window covers, which can be secured with a storm window kit due to their increased thickness.
Once the plastic film is securely attached, carefully trim the excess plastic from the edges. Use a sharp blade or scissors to cut away the excess material, ensuring a neat and tidy finish. Take your time with this step to avoid any accidental nicks or cuts to the plastic film.
Finally, inspect the window to ensure a tight seal has been created. Check for any gaps or openings where cold air could enter. If necessary, use additional tape or adhesive to fill any small gaps and create a stronger barrier.
By following these steps, you can effectively trim the excess film from the edges of your window, ensuring a snug and secure fit that will help keep the cold drafts out during the winter months.
