How to replace glass windows with polycarbonate sheet?


Are you planning on replacing the window glass yourself? 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.


Requirements for a DIY window replacement:

Clear polycarbonate sheet 6.4mm - 12mm (your choice of thickness)

Glass tape 4 mm thick

Filler plates

Glazing glue


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!

Replacing glass windows with polycarbonate sheets involves several steps. First, remove the existing glass carefully to avoid damage. Measure the window frame precisely and cut the polycarbonate sheet to fit. Secure the sheet in place using appropriate glazing or mounting methods. This process is similar to auto glass repair, requiring precision and care to ensure a proper fit and seal.

MAIN PROPERTIES OF MONOLITHIC SHEETS

Monolithic sheets is a material with an excellent combination of physical and mechanical properties, which are retained under various temperature conditions and humidity levels.
 

Polycarbonate sheets are an ideal replacement for traditional glazing materials. They are safe and easy to cut, install and use, almost impossible to break. Due to their low specific weight, polycarbonate sheets can significantly lighten and reduce the cost of the supporting structure in comparison with the structure in which glass is used, contributing to a significant reduction in transportation, handling and installation costs.
 

UV protection

Solar radiation has a detrimental effect on polymeric materials, causing their destruction and causing surface cracking of materials. These small cracks are further enlarged by water, dust and chemicals.

Polycarbonate monolithic sheets of this have a surface with an applied protective layer against ultraviolet radiation, which provides excellent resistance to weathering.
 

Arched glazing

All monolithic polycarbonate sheets are cold-formed into curved supporting glazing profiles. Provided that the bending radius of the sheet is greater than the minimum recommended value, the mechanical stress resulting from cold forming will not affect the mechanical properties of the sheet.

The guaranteed service life of the sheets is 15 years.
