RE: Can standard storefront doors be used above the first floor level?
To all concerned,
Storefront doors on upper floors generally are discouraged due to the potential for air and water infiltration problems that may result from higher pressures and exposure to rain on upper floors. Storefront doors are designed to be accessible and handle high traffic, but there are trade-offs that limit the ability to resist water and air infiltration. Buildings should be designed with overhangs and awnings above the entrances to limit the amount of contact with water.
Outswing storefront doors are better at resisting water infiltration than inswing doors because any weather-sweep on the threshold will help direct water away from the building.
