Take care when measuring, and consult a professional or manufacturer's guide if necessary to ensure accurate measurements.

Once you have a clear idea of the dimensions of the replacement and are sure that it's properly fitted, remove the glass from its frame. Make sure you work in a well-lit space and wear safety equipment, such as gloves, to avoid injuries from glass shards. Use a putty knife to remove the glazing beads or strips, which secure the glass to the frame, starting from around the edges of the pane. The glass is fragile, and you should be careful not to slip or stressing the frame.

The insulating cavity between the panes of glass is filled either argon gas or desiccant. In contrast to air, argon has less thermal conductivity, which reduces heat transfer through glass. Desiccants also absorb moisture from the air, preventing mould and condensation in the frame. The spacer bar is made of aluminum and is a vital part of the insulation system. Aluminium not only impedes heat transfer, but also keeps the edges warm of the window that is insulated to avoid condensation.

Checking Your Work
