The differences between residential and commercial doors can be many and varied, but for the most part come down to a handful of factors that include materials, security, looks, sturdiness and cost.
Broadly speaking, commercial doors tend to offer better security than residential doors, which are typically made of wood and somewhat lighter weight. A commercial door is more likely than a residential one to be made of steel or fiberglass, and may be thicker than its residential counterpart.
The merits of different door materials
Wooden doors can be more attractive visually than doors made from other materials, and for home use such doors are available in a wide variety of styles to blend in with surrounding décor. Of course, a business may want the door to its main entrance to be visually striking and attractive as well; some choose glass push/pull doors, heavier wooden doors, or more stylish-looking metal doors.
One reason a commercial door needs to be sturdier is that it gets opened and closed much more often than a residential door. A sturdier, heavier door that gets constant use also requires stronger hardware to match, such as the spring system that’s used to close some commercial doors.
With greater thickness and stronger materials comes higher cost, so commercial doors do tend to be more expensive than home doors. As with any purchase, a higher initial cost outlay may end up being worth it when the durability of the door over time is factored in.
