The basics of replacing garden shed windows
In this DIY, we’re assuming that you plan to replace your existing shed windows with acrylic sheet. Because we’ll saw the window panes to size for you free of charge, it’s fine to use budget (extruded) perspex as a replacement for traditional glass. If you’d rather cut the shed windows to size yourself or want to machine the PERSPEX® in a different way, then use cast acrylic. The thickness of PERSPEX® you need depends on the size of your window. For a small shed window, 2 mm thick PERSPEX® will be suitable. For larger summerhouse or shed windows, it is better to choose 3 mm or 4 mm thick acrylic. If you’re not sure, consult our thickness guide to discover the correct thickness.
Step 1: Remove the glazing beads from your polycarbonate shed windows
Before you can replace your garden shed windows, the first step is to remove the glazing beads. Only then can you determine the size of acrylic sheet that you need to order. To work out the correct size of your windowpane, you need to know the rebate size; this is the space in the frame without the glazing beads. Use a chisel or screwdriver to remove the glazing beads. Repeat this step for all the summerhouse windows that you intend to replace.
Step 2: Measure your garden shed window
Measure the size of your shed window. Then subtract 2 mm all around, because acrylic sheet expands with heat.
Step 3: Attach glazing tape to make your garden shed windows watertight
Apply glazing tape in the shed window frame, 2 mm away from the edge. Stick glazing tape to the back of the glazing beads, also at a distance of 2 mm from the edge.
Step 4: Position your summerhouse window
Now place the plastic windowpane in the rebate of your shed and then reattach the glazing beads.
Step 5: Seal your DIY shed windows
For a nice finish, seal your PERSPEX® summerhouse window neatly with glazing sealant. Seal both the front and back of the shed windows. Make sure that the sealant is worked in well between the connection of the glass and the glazing beads. Finally, we recommend regularly treating your window with an anti-static cleaner. This will prevent your summerhouse window from attracting dust, and it will stay looking beautiful for longer.
