The Ultimate Guide To Taping Plastic Windows

how do you tape a plastic window

Plastic film is often used to cover windows in the winter to prevent heat loss. The film is usually applied using double-sided tape, which can be purchased in kits or separately from stores like Lowes, HomeDepot, and Walmart. However, some people have reported issues with the tape not sticking properly, especially in basements. Alternative solutions to taping plastic over windows include using wooden or metal frames, but these can be costly and time-consuming. It's important to consider the potential for residue or damage when applying tape to windows and to follow instructions carefully to ensure a successful installation.

Using a hair dryer to tighten the plastic film

To begin, you'll need to gather your supplies: a hair dryer, plastic film, and a window squeegee or a smooth object like a credit card. It is optional to use a window kit, which provides a double-sided tape and a shrink film. If you don't have a kit, you can use regular tape and plastic film. Here are the steps to follow:

Start by cleaning the window frame thoroughly to ensure that the tape will adhere properly. If you're using a window kit, apply the double-sided tape that comes with it along the edges of the window frame. If not, use regular tape and apply it in the same way, making sure it's secure. It is important to note that you should leave one side of the tape backing on to prevent it from sticking to the film prematurely.

Now, unroll the plastic film and cut it to a size that is slightly larger than the window, giving yourself a few extra inches on all sides. Remove the remaining tape backing, and place the plastic film over the taped window frame, centering it as best as you can. Smooth out any wrinkles or bubbles with your hands as much as possible.

Here comes the hair dryer! Starting in one corner, turn on your hair dryer to a low or medium heat setting and direct the warm air towards the plastic film. Slowly and gently stretch and shrink the plastic with your hands as the warm air hits it. You'll notice the plastic tightening and becoming taut. Work your way around the entire window, being careful not to overheat one area for too long.

Once you've heated and tightened the plastic across the whole window, use a window squeegee or a smooth object like a credit card to firmly smooth out any remaining wrinkles and ensure a tight seal. Run the squeegee or card across the plastic in firm, steady strokes, working from the center outwards. This will remove any air bubbles and ensure the plastic is securely in place.

Finally, using a sharp utility knife, carefully trim the excess plastic film from around the edges of the window. Cut along the edges of the tape, being careful not to damage the window frame. Your plastic window covering is now complete and should provide an effective barrier against cold drafts. Enjoy the warmth!

Types of tape that work

When it comes to taping a plastic window, there are various types of tape that can be used effectively. The type of tape you choose will depend on your specific needs and preferences. Here are some options to consider:

Double-Sided Tape

Double-sided tape is a popular choice for attaching plastic film to windows, as it creates a strong bond between the two surfaces. It is available in kits specifically designed for window insulation, but it can also be purchased separately from stores like Walmart, Lowes, HomeDepot, and Amazon. When using double-sided tape, ensure that the window frame is clean before application for the best results.

Weather-Resistant Tape

If you are taping a plastic window in preparation for cold temperatures, consider using a weather-resistant tape. These tapes are designed to withstand low temperatures and maintain their adhesive properties. For example, a user on Reddit mentioned using a weather-resistant tape rated for temperatures as low as -10 degrees.

Window Film Mounting Tape

Window film mounting tape is specifically designed for attaching plastic film to windows. It offers strong adhesion and can be found at various retailers, including Amazon and Walmart. This type of tape is typically longer than standard double-sided tape, providing more coverage for your project.

Painter's Tape

For those concerned about damage to the window trim, using painter's tape in combination with double-sided tape can be a good solution. Apply the painter's tape around the window frame first, and then place the double-sided tape on top of it. This method can help reduce the risk of residue or damage to the trim when removing the tape.

Big Tape Window Plastic Film

Big Tape Window Plastic Film is a product designed specifically for repairing broken car windows. It comes in a 12-foot roll that is 17.5 inches wide and is known for its strong adhesion to both metal and plastic surfaces. This tape is waterproof and windproof, making it suitable for highway speeds. However, it is important to ensure that the vehicle is dry before application to avoid residue issues.

These are just a few types of tape that can be used for taping a plastic window. Each option offers unique advantages, so choose the one that best suits your specific requirements and budget.

Avoiding damage to walls and window frames

Taping plastic film over windows is a common practice to create a double-pane effect, which helps to cut down on heat loss during the winter. While taping plastic over windows, it is important to take certain measures to avoid damage to walls and window frames.

Firstly, it is recommended to avoid using duct tape, package-sealing tape, staples, or nails as these can leave stains, adhesive residues, or physical damage on walls and window frames. Instead, opt for specialised double-sided window tape, which can be purchased separately from stores like Lowes, HomeDepot, and Walmart, or online on Amazon. This tape is designed specifically for attaching plastic film to windows and will minimise the risk of damage.

When applying the tape, ensure that you follow the manufacturer's instructions carefully. Clean the window surface before applying the tape to ensure better adhesion. If possible, try to avoid applying tape directly to the walls, as this can increase the risk of damage when removing the tape. Instead, focus on taping the plastic film to the window frame itself.

Additionally, consider using alternative methods to secure the plastic film in place without relying solely on tape. For example, you can use spring-tension curtain rods or bamboo to hold the plastic in place, which reduces the need for excessive taping. These methods provide a neater result and are adjustable to fit most window sizes.

If you are experiencing issues with tape not sticking properly, consider using butyl rubber in a coiled strip. This can be pressed into the perimeter of the window frame, and the plastic can then be pressed into it, providing a secure hold without the need for excessive taping.

By following these suggestions, you can effectively tape plastic over your windows while minimising the risk of damage to walls and window frames.

Locating air leaks

Before taping a plastic window, it is important to locate any air leaks. Windows are a significant avenue for heat loss, especially in the winter. Locating and sealing these leaks can help improve the energy efficiency of your home. Here are some detailed and direct instructions to help you identify air leaks:

Firstly, you can conduct a visual inspection of your windows and doors. Check if there is any movement or rattling, as this could indicate a possible air leak. If you can see daylight around a window or door frame, this is a clear sign that the window or door is leaking.

Next, you can try a basic building pressurization test. Turn off any combustion appliances, such as gas furnaces or water heaters, and choose a cool, windy day. Open all the windows slightly and turn on exhaust fans that blow air outside, such as your clothes dryer or bathroom fans. Alternatively, you can use a large window fan to suck the air out of the room. This depressurization technique will help to increase infiltration through cracks and leaks, making them easier to detect.

Once you have depressurized the room, you can use various methods to locate the leaks. One simple method is to use a damp hand to feel for drafts. You can also light an incense stick and carefully pass it around the edges of common leak sites, such as windows and doors. Wherever the smoke wavers or is disturbed, there is a draft or leak.

Another method is to shine a flashlight at night over all potential gaps while someone observes the house from outside. Large cracks will show up as rays of light. You can also try shutting a door or window on a dollar bill. If you can pull the dollar bill out without any resistance, it indicates that air is escaping through the gaps.

Finally, for a more thorough and accurate measurement of air leakage, you can hire a qualified technician to conduct an energy assessment, including a blower door test. This test depressurizes the entire home and can reveal the location of many leaks, helping you identify areas that require additional insulation or sealing.

Removing tape and plastic film

Removing plastic film from window profiles can be challenging, and different approaches may be needed depending on the type of film and adhesive used. Here is a step-by-step guide to help you through the process:

Materials

  • Hair dryer or heat gun
  • Plastic scraper or credit card
  • Isopropyl alcohol or glue remover
  • Soft cloth or sponge
  • Warm soapy water
  • Razor blade (optional)
  • Gloves (to protect your hands)

Soften the Adhesive

Use a hair dryer or heat gun to gently heat the plastic film. Hold the heat source a few inches from the film and move it back and forth. This will soften the adhesive, making it easier to remove.

Peel Off the Film

Once the adhesive has softened, use a plastic scraper or credit card to gently lift one corner of the plastic film. Gradually peel the film away from the window, applying even pressure and pulling at a low angle. Work slowly and patiently to avoid leaving adhesive residue.

Remove Residue

After removing the film, there may still be adhesive residue on the window frame. Use a cloth soaked in isopropyl alcohol or an adhesive remover to gently rub off the residue. Be sure to test any chemicals on a small, inconspicuous area first to ensure they won't damage the window material.

Scrub and Clean

If there is still residue, mix warm soapy water and use a soft cloth or sponge to scrub the area. You can also use a plastic scraper or your fingernail to gently remove stubborn residue. Avoid using abrasive materials that may scratch the surface.

Rinse and Dry

Rinse the window with clean water to remove any remaining soap or adhesive remover. Dry the area with a clean, dry cloth.

Finishing

If there are still small bits of residue or stubborn stains, carefully scrape them off with a razor blade. Alternatively, you can use nail varnish remover, hairspray, or a product like Goof Off or WD-40 to remove any remaining residue.

Frequently asked questions

Heat-shrink plastic usually comes in kits that contain double-sided tape for attaching the clear plastic film. You can also use duct tape, staples, or even wooden battens and nails, but these may leave stains or damage the walls.
