Using adhesive tapes

Prepare the Window and Plastic Sheet

Firstly, ensure you have the right tools and materials. Purchase a plastic sheet that is slightly larger than your window to allow for a margin of error. You will also need adhesive tape, such as double-sided tape or painter's tape, and scissors or a utility blade.

Clean the Window Frame

Before applying the plastic sheet, it is essential to clean the window frame thoroughly. Remove any dirt, dust, or debris that may interfere with the adhesion of the tape. A clean surface will ensure that the tape sticks properly and reduce the risk of air leaks.

Apply Adhesive Tape

Once the window frame is clean, start applying the adhesive tape along the edges of the window. For double-sided tape, remove one side of the backing and press the tape firmly onto the window frame. Ensure that the tape is applied evenly and smoothly, creating a strong adhesive surface.

Attach the Plastic Sheet

With the tape in place, carefully unroll or unfold the plastic sheet. Starting from one corner, align the sheet with the window frame, and gently press the plastic onto the exposed adhesive tape. Work your way around the window, smoothing out any wrinkles or bubbles as you go.

Trim Excess Plastic

After the plastic sheet is securely attached, use scissors or a utility blade to trim away the excess plastic. Cut carefully and leave a small overlap, approximately 1 inch, to ensure full coverage. This will create a neater appearance and reduce the risk of the plastic peeling away from the tape.

Seal with Additional Tape

For added security and insulation, apply another layer of tape over the edges of the plastic sheet. This will help create a stronger seal and further reduce the possibility of air leaks. Overlap the tape at the corners for reinforced protection.

Using adhesive tape to cover outside windows with plastic is a simple and effective method to conserve energy, reduce drafts, and lower heating costs during the winter months.

Plastic Snap Lock Molding

Covering windows with plastic from the outside is a great way to save money during the winter months by reducing drafts and heat loss. Plastic window film covers are inexpensive, easy to install, and can be reused.

One way to attach plastic sheeting to outside windows is by using plastic snap-lock molding. This method can be more expensive than other options such as double-sided tape or furring strips. However, snap lock molding is a good option if you want to reuse the plastic sheeting every winter.

To cover your outside windows with plastic and snap lock molding, first, locate any air leaks around the window. You can do this by lighting an incense stick and holding it next to the seams or sash of the window. If the smoke is pushed in a particular direction, you likely have a leak.

Once you have identified any leaks, follow these steps:

  • Purchase a window film kit that fits the width of your window.
  • Install the snap lock molding strips by pressing them into place around the window frame. For exterior installation, use brad nails for added security.
  • Attach the plastic sheeting to the window, following the instructions provided with your window film kit.
  • Snap the plastic sheeting into place using the snap lock molding.
  • If needed, paint the snap lock molding to match the window frame.

By following these steps, you can effectively cover your outside windows with plastic, reducing drafts and heat loss during the winter months while also creating a reusable solution that can save you money in the long run.

Window film kits

The 3M Outdoor Window Insulator Kit, for example, helps protect your home from the cold. It keeps chilly drafts out and warm air in through its heat-shrink window film. The kit includes two-sided Scotch Window Film Mounting Tape to securely position the film. Installation is quick and easy, and the clear film stays up all season long without damaging the finish.

Another option is to purchase custom window film kits, such as the ComforTech Ceramic Series. These kits are cut to your specific window measurements and are available in a range of widths and lengths. However, there is typically a fee for custom orders, and returns are not allowed due to the custom nature of the product. Standard window film kits are also available for windows that fit into pre-set sizes.

When installing a window film kit, it is important to first determine if your window has any air leaks. This can be done by lighting an incense stick and holding it next to the seams or sash of the window. If the smoke is pushed in a particular direction, you likely have a leak. Locating air leaks can be tricky, so consider seeking professional assistance if needed.

Once you have identified any necessary repairs, follow the step-by-step instructions provided with your chosen window film kit. Remember to take down the plastic and remove the tape when the cold season is over.

Spring-tension curtain rods

Covering your windows with plastic is a great way to reduce drafts, making your house feel warmer in the winter and reducing moisture buildup on the window. This extra layer of plastic adds another layer of insulating air to reduce heat loss through the window.

  • Measure your window: Before purchasing your spring-tension curtain rod, measure the width of your window. Curtain rods typically come in adjustable sizes, such as 0-48 inches or 48-84 inches.
  • Purchase a spring-tension curtain rod: Look for a rod that can be adjusted to fit your window measurements. You can find these rods at home improvement stores, online, or at local hardware stores.
  • Prepare the plastic sheet: Cut the plastic sheet to size, ensuring it is slightly larger than the window. You can use a 6 mil plastic sheet, which is a common thickness for window covering.
  • Install the spring-tension curtain rod: Follow the manufacturer's instructions to install the rod securely above or around your window frame. The rod should be tight enough to stay in place but should not damage the window frame or surrounding area.
  • Hang the plastic sheet: Drape the plastic sheet over the curtain rod, ensuring it covers the entire window. You can use clips or rings to secure the top of the sheet to the rod if needed.
  • Secure the plastic sheet: Use tape or adhesive to secure the edges of the plastic sheet to the window frame. You can use double-sided tape or painter's tape, ensuring it will not damage the finish when removed. Avoid using strong adhesives that may be difficult to remove later.
  • Adjust as needed: Check that the plastic sheet is taut and adjust the curtain rod or the sheet as necessary. Ensure there are no gaps between the sheet and the window frame to maximize the insulating effect.

By following these steps, you can effectively use spring-tension curtain rods to cover your outside windows with plastic, helping to reduce heat loss and keep your home warmer during the cold months. Remember to remove the plastic and tape when the winter season is over, and store the curtain rod and plastic sheet for reuse next year.

Heat-shrink plastic coverings

To begin, purchase a window film kit that fits the width of your window. These kits are available in several sizes at home improvement, hardware, and discount stores. The plastic film typically comes in window-sized pieces, and you may want to choose a larger size to have a margin for error. You can always trim the excess plastic later.

Before applying the plastic, check for any air leaks around your window. Light an incense stick and hold it next to the seams or sash of the window. If the smoke is pushed in a particular direction, you likely have a leak.

Now, follow these steps to apply the heat-shrink plastic covering:

  • Remove the rotating wand from your mini-blinds, if you have any, before applying the plastic. Lift the retaining ring and lift the wand off the hook.
  • Place the plastic film over the window, making sure it is larger than the window frame.
  • Use bamboo rods or spring-tension curtain rods to hold the plastic in place. For a neater result, you can use two rods at the top and bottom of the window.
  • Apply heat to the plastic to shrink it in place. You can use a hairdryer or a heat gun for this step.
  • Once the plastic has shrunk, cut out the center of the square around the wand hook with a utility blade.
  • Reinstall the wand and pull out the lift cords.

After the winter, simply remove the plastic and any tape used. This method will not damage the finish of your window trim.
