What are the differences between outswing and inswing exterior doors, and how do these differences impact their functionality and installation?

Outswing exterior doors swing outward, while inswing doors swing inward. The direction of swing impacts functionality and installation. Outswing doors are more secure and weather-resistant, but require more space outside. Inswing doors are easier to seal and insulate, but can be blocked by snow or debris. Installation requirements vary based on the swing direction and location of hinges.
