I broke the glass in a ~30 year old Andersen casement window.
Can I replace the glass myself, or do I need to replace the
entire sash? There are some rubber tabs on the inside of the
sash that I don't know what the function is -- I removed one
of them and they don't seem to do anything. The glass is embedded
in the sash such that it doesn't seem possible to take it out by
removing the glazing as in other windows. It would be much cheaper
for me to replace the glass only if that is possible. Thanks,
