Frequently Asked Questions

View More Frequently Asked Questions
  • What is the difference between commercial and residential doors?

    Residential doors are intended to be used only a few times each day, and are built out of materials that can withstand the wear and tear of a normal household. Residential doors are also certified to provide a certain degree of security when used with higher-grade hardware. Commercial doors are intended to be opened and closed multiple times per day. They are also designed to be used with commercial-grade hardware that is more durable and of a higher security grade.

  • How big is a commercial door frame?

    32-48 inches wide by 80 inches tall: The International Building Code (IBC) specifies a minimum of 32 inches (2.67 feet) and a maximum of 48 inches for commercial doors. There are, however, exceptions. Doors at medical facilities, for example, must be at least 41.5 inches wide to allow hospital beds to move in and out of rooms. Swinging doors that do not have a mullion – or a partition between the doors – must have at least one 32-inch-wide door leaf. With limited exclusions, the IBC specifies that commercial doors must be at least 80 inches tall.
