• Installation – retrofit windows being inserted into existing frames, they are quicker, easier and cheaper to install than new windows. However, the frames on old buildings might not be perfectly square, which might cause problems while installing retrofit windows;
• Usage – while retrofit windows can only go into existing frames, therefore they can only be used on finished buildings, new-construction windows can be used on old buildings as well as to replace old windows.
