What You'll Learn
Measure the window and cut the perspex/acrylic to size
To glaze plastic double-pane windows, you will need to measure the inside of your window opening accurately and cut the perspex/acrylic to the right size. Here is a step-by-step guide to help you through the process:
Step 1: Measure the Window Opening
Use a measuring tape to get the dimensions of the window opening. Measure the width and height of the glass only, and subtract 1/8 inch from each measurement. This will give you the size of the perspex/acrylic pane you need.
Step 2: Mark the Cut Lines
Before cutting the perspex/acrylic, lay out the material on a flat surface and use a straight edge to mark the cut lines. Clamp the straight edge in place to ensure a straight and accurate cut.
Step 3: Score the Perspex/Acrylic
Using a sharp knife, carefully score along the marked cut lines. Make sure to wear safety glasses to protect your eyes during this step. The thicker the perspex/acrylic, the harder it will be to cut. For thicker sheets, consider making multiple passes to create a deeper score on both sides.
Step 4: Snap the Perspex/Acrylic
Once you have a deep enough score, you can snap the perspex/acrylic along the score line. Place the sheet on a table or stair edge and apply pressure to snap it. If needed, have someone assist you by putting their weight on the sheet to keep it stable.
Step 5: Edge Polishing (Optional)
If desired, you can polish the edges of the perspex/acrylic to achieve a smooth and glossy finish. This step will remove any cutting marks and improve the overall appearance of the window pane.
Step 6: Test Fit the Pane
After cutting the perspex/acrylic to size, test-fit the pane in the window opening. Ensure that the pane fits securely and that there are no gaps or spaces that could allow air leakage.
Remember to handle the perspex/acrylic with care as it can have sharp edges if the cutting process doesn't result in a clean break. Additionally, you can always seek professional assistance or order pre-cut panes from window manufacturers if you feel uncomfortable with the cutting process.

Attach self-adhesive magnetic strips to the perspex/acrylic
Glazing plastic double-pane windows with Perspex or acrylic sheets is a cost-effective way to improve insulation and prevent drafts. To attach self-adhesive magnetic strips to the Perspex/acrylic, follow these steps:
First, measure the perimeter of your window to determine the required length of the magnetic strips. Purchase self-adhesive magnetic strips that are 1cm wide and ensure you have enough to cover all four edges of the Perspex/acrylic sheet.
Next, carefully peel off the backing of one magnetic strip and attach it to the Perspex/acrylic sheet, aligning the edges so that all four sides have a full-length strip. Cut the strip to size if necessary, using craft scissors. Ensure the strip is securely adhered to the sheet, creating a strong bond.
Now, you will need assistance from another person. Hold the Perspex/acrylic sheet in position against the window frame while your assistant slowly peels off the backing of the second adhesive strip. This strip will adhere to the window frame. As the paper backing is removed, carefully press the Perspex/acrylic sheet onto the window frame, ensuring that the magnetic strips on the sheet and the frame align and are attracted to each other.
Repeat this process for all four sides, ensuring that the strips are securely attached and the sheet is firmly in place. Once complete, you will have a well-insulated window with an additional layer of Perspex/acrylic.
For a more permanent solution, some sources suggest using epoxy glue or drilling small holes into the acrylic to secure the magnets. However, drilling may be challenging and there is a risk of shattering the acrylic, so it is important to proceed with caution.

Trail fit the perspex/acrylic onto the window frame
Trail fitting the perspex/acrylic onto the window frame is a crucial step in the process of adding an extra pane to your windows. Here's a detailed guide on how to approach this step:
First, measure the inside of your window opening. It is recommended to subtract 1/8 inch from your measurements to ensure an accurate fit. This will be the size of your acrylic or perspex pane. Mark the measurements on the perspex/acrylic sheet with a pen or pencil. If your window has latches, it's important to note that the extra insulating layer must be the exact same size as the glass pane.
Next, carefully cut the perspex/acrylic sheet to size. Acrylic is relatively easy to trim with a sharp knife, clamps, and a straight edge. For thicker acrylic, consider using a power saw, but always wear safety glasses for eye protection. Score the acrylic along your marked measurements with the knife. Then, using a table or stair edge, snap the acrylic along the score mark. If needed, have someone apply their weight to the sheet to keep it stable.
Now, you're ready for the trail fit. With the help of an assistant, carefully position the cut perspex/acrylic sheet onto the window frame. Ensure that the sheet is properly aligned and fits securely within the frame. Check that the edges of the sheet are flush with the frame and make any necessary adjustments. At this stage, you can also mark the positions of the magnetic strips or adhesive tape that will be used to secure the sheet in place.
Once you're satisfied with the trail fit, you can proceed to the next steps of adding the insulating layer and securing the perspex/acrylic sheet to the window frame. Remember to refer to the other steps in the process for a comprehensive understanding of how to glaze plastic double-pane windows.

Peel off the paper backing and stick the perspex/acrylic to the window frame
Glazing plastic double-pane windows can be a great way to improve your home's energy efficiency and insulation. One option for doing this is to use perspex or acrylic sheets as the indoor layer, held in place with magnetic strips.
When you are ready to mount the perspex/acrylic to your window frame, you will first need to peel off the paper backing. This protective paper can sometimes be challenging to remove, especially if the adhesive has dried due to improper storage. Here are some tips to help you remove the paper backing effectively:
- Use a hairdryer or heat gun on a low setting to heat up the adhesive and loosen the paper's grip. Be careful not to overheat, as this could cause distortion or fire issues.
- Try using chemical cleaners or solvents like WD40, light oil, rubbing alcohol, or a citrus-based cleaner. Spray it on, let it soak, and then peel off the paper. Be sure to follow the manufacturer's instructions and safety guidelines when using chemicals.
- Soak the acrylic sheet in warm water for about 30 minutes. The water will weaken the paper, allowing it to disintegrate or be easily torn off. Ensure the water is not too hot, as it could damage the acrylic.
- Use duct tape or tape to stick onto the corner of the paper backing. Then, peel off the tape, and the paper should come off with it.
- For stickers, you can heat them with a hairdryer and then slowly tear them off. You can also use an eraser to remove any residual adhesive, but be sure to clean up the crumbs.
Once you have successfully removed the paper backing, you can proceed to stick the perspex/acrylic to your window frame. Ensure the magnetic strips are properly aligned and adhere firmly to the window frame. The air trapped between the layers of glass will help insulate the room, and you will have successfully glazed your plastic double-pane windows!

Seal the window with putty or calk
When glazing plastic double-pane windows, sealing the window with putty or caulk is a crucial step to ensure a smooth finish and effective insulation. Here's a detailed guide on how to do it:
Preparing the Window for Putty or Caulk
Before applying putty or caulk, it's essential to prepare the window properly. If you're working with an old window, remove any broken glass shards and old putty or caulk. Put on safety gear, such as heavy gloves and eye protection, to protect yourself during this process. Use a hammer to break up the glass, and then pull out the pieces by hand. Pliers can be useful for removing old glazing points. If the putty or caulk is in poor condition, use a putty knife to pry away large chunks. For more stubborn sections, use a heat gun to soften the material before gouging it out. Be cautious to avoid burns and keep the heat gun constantly moving.
Applying Putty
Glazing putty acts as an adhesive, bonding the glass to the window frame and creating a durable seal. Start by cleaning the glass edges thoroughly. Then, roll the putty into a long, thin sausage shape between your thumb and finger. Place this roll of putty around the edges of the glass. Push the glass against the frame, ensuring a firm fit. Remove any excess putty with a knife. Insert glass points around the outside to secure the glass temporarily while the putty dries. Finally, roll the putty into a golf ball-sized shape and push it into the corners, squeezing it from corner to corner. Smooth out the excess putty with a knife to create a neat finish. Depending on the type of putty, you may need to wait several days before painting. Always check the manufacturer's instructions for drying and painting recommendations.
Applying Caulk
Caulk is used to seal gaps and cracks around windows, preventing leaks, drafts, and moisture damage. Select the appropriate type of caulk for your specific application, considering factors such as interior or exterior use, humidity levels, and weather conditions. Clean the area thoroughly before caulking. Load the caulk into a caulk gun and apply a steady bead along the desired areas. Ensure that you don't stop while caulking, as it may affect the smoothness of the bead. Smooth the caulk with a wet finger, a plastic spoon, or a specialised smoothing tool. For exterior caulking, choose a weather-resistant caulk and apply it during dry, mild weather.
Additional Tips for an Effective Seal
When working with putty, it's important to ensure that it is sealed around the entire window frame. Any loose or missing sections can lead to leaks and drafts. Putty can take a significant amount of time to fully cure and harden, so be cautious of rain or moisture affecting the freshly applied putty. If you're using caulk, remember to never apply it over existing, cracked caulk. Always remove the old caulk first, as applying new caulk over cracked caulk will result in an ineffective seal and an unsightly finish. Additionally, avoid caulking the bottom of the exterior window trim if it has drainage gaps or weep holes, as sealing these can lead to water damage.

Frequently asked questions
Double-glazed windows have twice the energy efficiency of single-glazed windows as they have two panes of glass, creating an air cushion that provides better insulation and prevents drafts. Plastic is the cheapest material for double glazing, followed by second-hand glass and then acrylic.
You will need perspex or acrylic sheets that are 2-3mm thick, self-adhesive magnetic strips, craft scissors, a heat gun, a putty knife, leather gloves, and protective eyewear.
First, measure your window and cut the perspex or acrylic to size. Then, peel off the backing of the magnetic strip and attach it carefully, aligning the edges so that all four edges have a full-length strip. Cut off a similar length of strip and place it on the strip that is already attached to the acrylic. Hold the acrylic in position and slowly peel off the backing for the second adhesive strip. Press the acrylic onto the window frame. Repeat so that all four sides are stuck down.
Prime the wood sash with an oil-based primer and let it dry. Apply 1/8 inch of glazing compound to the backstop of the sash. Place new glazing points or spring clips every 8 inches or so, using a putty knife to gently press them into the wood. Be careful not to put pressure on the glass or bend the points.
