This is the answer to the question Is it reliable if the windows are shipped separately from the frames?
Revision 1
I have only seen this once with aluminum elements because the elements were too big to transport and therefore could only be assembled on the building site. This does not apply to PVC windows whose corners are welded and plastered.
As a rule, fixed glazing and large elements are transported separately. In the case of fixed glazing, because the glass will still have to be removed when installing the frame, and in the case of large elements – because of the heavy weight and the associated difficulties in moving during installation.
Some window manufacturers transport the glass separately because they expect there will be handling advantages during installation. This is a matter of persuasion. The vast majority of window manufacturers do not.
