How to quickly distinguish between inward and outward opening Windows?
If you're not sure what kind of window you have at home, here are three tips to help you quickly determine:
Look direction: When standing indoors, is the glass door opening inward or outward?
Look at the hardware: if the hinges (leaves) are on the outside, it's an exterior-opening window; if all the hardware is on the inside, it's an interior-opening window.
Touching the edge: An exterior-opening window is one where the entire window sash can be easily touched at its edges indoors, while an interior-opening window has its sash edges enclosed by the frame.
