The deterioration of the seal may be caused by environmental factors, such as exposure to direct sunlight or the use of chemical cleaners that may harm the glass and erode the seal.

Position your calipers on the frame and secure them against the existing unit to gauge its thickness. This will reveal the dimensions of the newly sealed unit, allowing you to purchase it according to the exact measurements.
Utilize a utility blade to carefully cut the adhesive strip that keeps the window in place. Once you've removed the strip then gently lift the glass off the frame using a putty knife or shovel.
