Are you planning on replacing the window glass of a shed? Whether you’re replacing a wooden window or one with a plastic frame, follow our simple step by step instructions to make a success of this DIY project.
The material for making a shed window
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 budget plexiglass (extruded) to replace the shed window glass, and we can cut it to the exact size you need for free. If you want to cut the plexiglass yourself, then we recommend choosing clear cast acrylic sheet 20 mm thick. If you would like more privacy, opt for frosted acrylic sheet.
The difference between extruded and moulded acrylic lies in the production process. Extruded or cheap acrylic sheet is rolled to the desired thickness after casting. The process creates tension on the sheet and makes it more liable to break. This means it’s harder to machine than the moulded version. Cheap acrylic sheet is the economical choice if you need glass for applications that are not heavily used, such as a barn door window in our example.
1: Remove the glass battens
To decide on the size of the shed window acrylic 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 prise them out.
2: Measure the window
Measure the window and subtract 2 mm all round. This is to allow for the Plexiglass 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 Plexiglass window in the frame.
5: Attach the window battens
Next, it’s time to attach the glass battens. Use a drilling machine for this task.
6: Finishing the window
Give your Plexiglass 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 Kenotek Brilliant detergent and voila: your replacement shed window is complete!
