So my neighbour is building his cave, and he was hoping to slide 12 foot sheets of drywall thru his basement window.

The window in question is a one pane slider. The other pane seems fixed with no obvious way to remove it. There appear to be no screws or anything holding the window in place to the frame.

If this helps the house is in new Brighton and it is 10 years old. There appear to be no markings on the window to suggest a brand name.

Anyone have any thoughts on how to remove the pane without breaking it. His stairwell winds so getting anything more than 8 foot sheets thru the stairs seems out of the question.
