The material for making a DIY window replacement
In this DIY blog, we’ll take a new barn door without a window as our example so we don’t need to remove the glass slats. We’ll be using clear polycarbonate sheet (solid) to replace the window glass, and we can cut it to the exact size you need for free. If you want to cut the polycarbonate yourself, then we recommend going to our blog on how to cut polycarbonate sheets .
1: Remove the glass battens
To decide on the size of the window polycarbonate that you need to order, first remove the glass battens from the window that you want to replace. You need to measure the rebate size or the space in the frame without the glass battens. Remove the glass battens using a chisel or a screwdriver to pull them out.
2: Measure the window
Measure the window and subtract 2 mm all round. This is to allow for the polycarbonate expanding as the temperature rises.
3: Apply glass tape
Apply glass tape around the frame, 2 mm away from the edge. Then stick glazing tape on the back of the glass battens, once again 2 mm from the edge.
4: Position the window
Fill in the rebate with filler plates approximately 3 mm thick, also known as glass cubes. Next position the polycarbonate window in the frame.
5: Attach the window battens
Next, it’s time to attach the glass battens. Use a drill for this task.
6: Finishing the window
Give your polycarbonate window a neat, secure finish with glazing glue. Do this at both the front and the back of the window. Make sure that the glue is also applied between the windowpane and the glass battens. Clean your window using warm water and a few drops of plastic cleaner: your DIY window replacement is complete!
