Replacing a broken window pane with plexiglass is a relatively simple process that can be done by following these steps:
1. Measure the size of the broken window pane accurately.
2. Purchase a piece of plexiglass that matches the measurements.
3. Remove the broken glass from the window frame carefully.
4. Clean the window frame and remove any remaining glass shards.
5. Apply a thin layer of silicone caulk around the edges of the frame.
6. Place the plexiglass into the frame, ensuring it fits snugly.
7. Secure the plexiglass in place using glazier’s points or screws.
8. Apply another layer of silicone caulk around the edges to seal the glass.
9. Allow the caulk to dry completely before using the window.
By following these steps, you can easily replace a broken window pane with plexiglass, which is a durable and shatter-resistant alternative to traditional glass.
When plate glass breaks, it poses a danger to both the window and the area below it. If you are looking for alternatives to plate glass, consider tempered or laminated glass, which are less hazardous when shattered. However, there is an even safer option you may not have thought of.
Acrylic plexiglass sheets are 17 times stronger than glass and are also more affordable and transparent. For homeowners in need of immediate window repair, plexiglass is easier to cut and handle, making it a sensible choice. Replacing a broken window pane with plexiglass is a straightforward process.
How to Cut Plexiglass
You can cut plexiglass yourself with a circular saw or table saw, unlike tempered or laminated glass that needs to be precut at the factory. Use a metal and plastic cutting blade for the best results. Keep the protective coating on the plexiglass, mark the cut line, and carefully cut along the line. The rough edges should not be a problem once the plexiglass is installed in the window, but you can smooth them with sandpaper if desired.
If the plexiglass is thinner than 3/16 inch, you can also use a utility knife to cut it. Score a series of lines along the cut line, flip the sheet, and repeat on the other side. Then, place the sheet on the edge of a workbench and snap it along the score line.
Removing the Broken Glass Safely
After cutting the plexiglass to the required dimensions, put on gloves and goggles, and begin by removing the broken glass from the window. Collect all the glass on the floor and dispose of it in paper, not plastic. Remove any loose shards of glass from the window and place them in a bag.
Use pliers to grip and remove any stuck shards. Some may require scraping off the old window putty, which can be done with a flat-head screwdriver or stiff putty knife. If the window has plastic or wood stops, use a screwdriver to pry them out. Once all the putty and stops are removed, use pliers to extract any glazing points, which are small triangular metal pieces embedded in the frame to hold the glass.
Installing the Plexiglass
The installation process for plexiglass in a window frame is similar to that of glass. Apply a bead of clear silicone caulk on the frame for weather sealing. Remove the protective coating from the plexiglass and fit it into the opening. Use a few glazing points to secure it in place and allow the caulk to set for a few hours.
After securing the plexiglass with caulk, you have the option to cover the outer edges with glazing putty or paintable caulk. If the wooden stops from the old window are still in good condition, you can use them to conceal the edges of the new window. However, you will need to remove the glazing points before attaching the stops to the window frame with 1-inch brads or finishing nails. To prevent cold air from entering, it is still necessary to apply a line of paintable caulk between the stops and the window.
