How to Put Plastic on Windows: A Comprehensive Guide

Greetings, dear readers! Winter is just around the corner, and with it comes the need to prepare our homes for the chilly weather ahead. One way to keep warm indoors is by putting plastic on windows to keep cold drafts at bay. It’s a cost-effective and straightforward solution that can save you money on heating bills. In this article, we’ll guide you through the steps on how to put plastic on windows.

Steps on How to Put Plastic on Windows

Step 1: Measure Your Windows

Before beginning, it’s crucial to measure your windows to determine the size of plastic needed. Measure the length and width of each pane and add a few inches to each measurement.

Step 2: Clean the Window

Thoroughly wash the window and wipe it dry to ensure there’s no dirt or dust on the surface. This step is necessary to ensure that the plastic sticks well to the window.

Step 3: Apply Double-Sided Tape

Cut the double-sided tape to match the size of the window frame and apply it along the edges, leaving a small gap between the tape and the glass’s edge.

Step 4: Cut the Plastic to Size

Cut the plastic sheet to match the size of the window, taking care to add a few extra inches on all sides.

Step 5: Attach Plastic Sheet to Tape

With the double-sided tape in place, press the plastic sheet onto the tape, starting from the top and working your way down. Using a squeegee or credit card, smooth out any wrinkles in the plastic sheet.

Step 6: Use a Hair Dryer to Shrink the Plastic

Using a hairdryer, gently heat the plastic sheet, starting at the top and working down. The heat causes the plastic to shrink and tighten, creating a tight seal.

Step 7: Cut Excess Plastic

Once the plastic has shrunk, use a pair of scissors to trim any excess plastic from the edges of the window.

Step 8: Seal the Plastic

Using a heat gun or hot iron, carefully seal the edges of the plastic to the window frame. This step ensures that the plastic remains taut and secure.

Step 9: Repeat for All Windows

Repeat the above steps for all the windows in your home that need to be covered with plastic.

Step 10: Reinforce Plastic with Strips of Tape

Once the plastic is sealed, reinforce it with strips of tape at the top, bottom, and sides. This step enhances the plastic’s durability and prevents it from peeling off the window.

Step 11: Monitor for Damage

Check your windows regularly for any tears or damage to the plastic. If any damage is found, remove and replace the sheet.

Step 12: Remove the Plastic in Spring

When spring arrives, carefully remove the plastic from the windows. Use caution not to damage the window frame or glass while taking off the plastic sheet.

Tips and Tricks

Tip 1: Use a Hairdryer on Low Heat

When using a hairdryer to shrink the plastic, set it on low heat to avoid damaging the plastic.

Tip 2: Use Frost-Free Plastic

When purchasing plastic for your windows, look for Frost-Free plastic to prevent any fogging or frosting on your windows.

Tip 3: Clean Thoroughly

Ensure that your windows are thoroughly cleaned before attaching the plastic sheet. Any dirt or dust can cause the sheet to peel off.

Tip 4: Apply Tape Around the Perimeter

To enhance the plastic’s durability, apply thick strips of tape around the perimeter of the window.

Tip 5: Use a Credit Card to Smooth Out Wrinkles

Use a credit card or squeegee to smooth out any wrinkles in the plastic sheet.

Tip 6: Check Weather Stripping

Check the weather stripping around your windows. If there are any leaks or gaps, repair them before applying the plastic sheet.

Tip 7: Use a Heat Gun with Caution

If using a heat gun to seal the plastic, be very careful not to overheat and damage the plastic or the window frame.

Tip 8: Remove Plastic During Warmer Months

Remember to remove the plastic from your windows during the warmer months to avoid damage to your window frames.

Tip 9: Recycle Old Plastic

Consider recycling old plastic sheets instead of throwing them away.

Tip 10: Check for Rebates or Discounts

Check with your local energy provider to see if they offer any rebates or discounts for installing plastic on your windows. In conclusion, putting plastic on windows is a cost-effective and easy way to keep your home warm during the winter months. With the steps outlined in this article, you can ensure that your plastic film is applied correctly and safely. Remember to follow safety guidelines and take caution while using heat guns or irons. With diligence and care, you’ll enjoy a warm and cozy home all winter long.
