Prepare the window surface

Before installing 20 mil plastic on your window, it is important to prepare the window surface. This process will ensure that the plastic adheres properly to the window and will help create an airtight barrier. Here is a step-by-step guide to preparing the window surface:

Firstly, ensure that the window is clean and dry. Use a soft cloth and a mild soap and water solution to gently wipe down the window, removing any dust, dirt, or grime. Avoid using harsh or abrasive cleaners, as these can scratch or dull the window surface. Once you have finished cleaning, rinse the window with clean water to remove any soap residue. Allow the window to dry completely before proceeding to the next step.

Next, measure the window's width and height. This step is crucial for purchasing the correct size of plastic sheeting or window kit. Window kits typically come in various sizes, so you will need to select one that fits the width of your window. You can also purchase clear plastic vinyl sheets, which are flexible and easy to cut and install. If you go this route, cut the vinyl sheet to the desired size, adding a small extra margin of about 1 inch.

Before applying the plastic, ensure that there are no obstacles on the window that might interfere with the adhesion. For example, if you have mini-blinds, you may need to remove the rotating wand by lifting the retaining ring and lifting the wand off the hook. You can then apply the window film and shrink it in place before reinstalling the wand and pull cords.

Once the window is clean, dry, and free of any obstructions, you are ready to begin installing the plastic. Follow the instructions provided with your chosen window kit or plastic sheeting for specific application guidelines. Remember to smooth out any wrinkles or air bubbles as you apply the plastic to ensure a flat, wrinkle-free finish.

Cut the plastic to size

Cutting plastic sheeting to size is a crucial step in installing 20 mil plastic windows. While off-the-shelf kits are available in standard window sizes, you may need to cut the plastic to fit your specific window dimensions. Here is a detailed guide to help you through the process:

First, it is important to understand the type of plastic you are working with. Different types of plastic have varying levels of thickness and flexibility, which will impact the cutting method you choose. Common types of plastic used for windows include polyethylene, acrylic (also known as Plexiglas, Perspex, or Lucite), and polycarbonate. Each type has unique characteristics that may influence your cutting approach.

Next, you'll want to gather the right tools for the job. For thinner plastics, a sharp utility knife or a craft knife can be used to make precise cuts. Ensure the blade is new or freshly sharpened to achieve clean cuts and avoid tearing the plastic. For thicker plastics, you may need to consider power tools such as a table saw with a fine-tooth blade or a Dremel tool with a router bit. If using a Dremel, consider using it under water to prevent the plastic from melting during the cutting process.

Before cutting, carefully measure your window's dimensions and mark the plastic sheet accordingly, allowing for a small extra margin (about 1 inch) around the marked area. This extra margin can be trimmed once the plastic is installed, ensuring a perfect fit. When cutting, take your time and aim for straight, smooth cuts. Go slow, as rushing can lead to uneven edges or mistakes. If you are cutting thicker plastic, consider drilling small holes along the cutting line to help guide your cuts and reduce the risk of cracking or chipping.

Finally, once you have cut the plastic to size, it is important to handle the cut edges with care. Depending on the type of plastic, you may need to file or sand the edges to smooth them out and remove any sharp burrs or imperfections. This will ensure that your plastic window is safe to handle during installation and will not catch or tear surrounding materials.

By following these steps and choosing the appropriate tools and techniques for your specific plastic type, you can confidently cut your plastic sheeting to size, setting yourself up for a successful 20 mil plastic window installation.

Attach the plastic

Attaching the plastic is a crucial step in installing a 20-mil plastic window covering. While there are various methods to choose from, the goal is to create an airtight barrier that reduces drafts, adds insulation, and prevents heat loss. Here are some detailed instructions for attaching the plastic:

Prepare the Window and Plastic Film

Before attaching the plastic film, ensure the window is clean and free of dust and debris. Measure the window's width and height, and cut the plastic film to size, leaving a small margin of about an inch on all sides. For thicker films, precise cutting to the window's dimensions is recommended, as trimming afterwards may be challenging. When working with tightly rolled films, allow them to lay flat before making any cuts.

Adhesive Tapes

Double-sided adhesive tapes are a common method for attaching plastic film to windows. These tapes are included in many window film kits. Apply the tape around the perimeter of the window frame, pressing it firmly in place. Then, carefully remove the backing from the tape, and smooth the plastic film over the exposed adhesive, working from top to bottom to avoid trapping air bubbles.

Squeegee Technique

After adhering the plastic film to the tape, use a squeegee to smooth out any remaining air bubbles. Start from the centre and work outwards, applying even pressure. For best results, spray a soapy solution onto the plastic film before using the squeegee. Use the black felt side of the squeegee for most areas and the plastic or rubber side for precision in corners.

Spring-Tension Curtain Rods

An alternative method is to use spring-tension curtain rods to hold the plastic film in place. Cut the plastic slightly larger than the window opening, allowing for a margin of error. Bend and place two bamboo rods inside the window opening, allowing the bamboo to tension itself against the corners. Pull back the bamboo, and place the plastic between it and the window frame. This method provides a neat finish and is adjustable for various window sizes.

Other Methods

While less common, other techniques for attaching plastic film include using wooden or metal frames, wooden battens and nails, duct tape, or staples. These methods may leave stains or physical damage on the surrounding walls, so they are not ideal for renters or those concerned about property damage. Additionally, some individuals opt for plastic snap lock molding, which provides a reusable solution, although it can be more expensive.

Smooth out air bubbles

When installing a 20-mil plastic window, you may encounter air bubbles that can be difficult to remove. Here are some detailed instructions to help you smooth out these air bubbles and achieve a flawless finish:

Identify the Type of Bubble

Before you begin, it's important to identify the type of bubble you're dealing with. There are typically two types of bubbles: air bubbles and water bubbles. Air bubbles are caused by air trapped between the film and the glass, resulting in a hazy appearance. Water bubbles, on the other hand, are formed due to moisture trapped between the film and the window.

Prepare Your Tools and Work Environment

Gather the necessary tools, including a squeegee, a heat gun or hair dryer, mild dish soap, a spray bottle, and a lint-free rag. Ensure your garage or workspace is warm, as this will help keep the film moist and flexible during the process.

Use a Squeegee

The squeegee is your primary tool for smoothing out air bubbles. Spray the film with a mild dish soap and water solution to moisten it—just enough to make it damp, not soaking wet. Hold the squeegee at a 45-degree angle and start from the outermost edge of the bubble. Firmly press down and slide the squeegee towards the centre in long, smooth strokes. This will help push the air out from under the film.

Pop Larger Air Bubbles

For larger air bubbles that are stubborn and persist, you may need to take additional steps. Try rewetting the film and using the squeegee again. If this doesn't work, slowly lift a corner of the film to allow the trapped air to escape, then reapply the film to the glass. You can also use an air release pen, a fine needle, or a pin to make a tiny hole in the centre of the bubble. This will help release the air and reduce the size of the bubble. Just be careful not to tear the film or scratch the glass.

Final Touches

Once you've removed the air bubbles, spray the installed film with your applicator solution to ensure a tight bond against the glass. Go over the film one last time with your squeegee tool to smooth out any remaining imperfections. Finally, use a lint-free rag to wipe away any excess applicator solution from the film. Allow the window to dry completely before considering the job done.

Maintain and clean the plastic

Maintaining and cleaning plastic windows requires a different approach from cleaning glass windows. Plastic windows are prone to aging and browning and, if neglected, can become a safety hazard. Regular cleaning and maintenance can extend the life of plastic windows. Here are some tips to keep your plastic windows in great shape:

Cleaning

  • Before treating the window, ensure it is clean by removing any dust and debris with a soft cloth, soft-bristled brush, or a damp cotton terry towel.
  • Avoid using abrasive materials such as steel wool or harsh brushes, as these can scratch the plastic and compromise its integrity.
  • For the cleaning solution, you can use a few drops of mild dish soap with warm water or a specialised PVC cleaner. Avoid harsh chemicals as they can damage the plastic surface.
  • Dip a microfiber cloth or sponge into the soapy water and gently wipe the entire surface of the window, focusing on areas with stubborn stains or grime. Avoid applying excessive pressure to prevent scratching.
  • For persistent stains, use a soft-bristled brush dipped in the cleaning solution and gently scrub in circular motions.
  • Rinse the cloth or sponge with clean water and wipe the window again to remove any soap residue.
  • You can also create your own eco-friendly cleaning solution by mixing equal parts white vinegar and water in a spray bottle. Vinegar's acidic nature helps break down grime and stains. Alternatively, combine the juice of two fresh lemons with two cups of water for a refreshing scent.
  • For grease spots, use a sponge, hot water, and a mild detergent.

Maintenance

  • Set a routine for cleaning your plastic windows. Depending on your location and environmental factors, a quarterly cleaning schedule is generally sufficient.
  • Periodically inspect your plastic windows for any signs of damage, such as cracks or warping. Addressing issues promptly can prevent more significant problems and ensure the longevity of your windows.
  • Avoid common cleaning mistakes, such as using abrasive materials or harsh chemicals, which can inadvertently damage the plastic.
  • If your window becomes cloudy due to scratches and oxidation, you can polish the surface using a product like No. 2 One Step Polish. Ensure the window is clean and cool to the touch before applying the polish with a cotton terry towel.
