An Overview of Commercial Door Thresholds

Commercial door thresholds provide an aesthetically pleasing way to conceal the difference between two-floor materials between rooms. Their other main function is to help block rain, snow, or outside air from entering a building. Exterior doors should always use a door threshold, sometimes paired with a weather strip, to block the outdoor elements from entering the building. Commercial door thresholds give businesses a cleaner look and can help save money on energy costs.

Which Type of Door Threshold is Right for Me?

When choosing a door threshold, you should consider where the door is located and what the rooms on either side of the door will contain. Different commercial door thresholds are better at certain applications than others. Identifying your specific situation first will help point you in the right direction to decide which door threshold is best. QualityDoor has commercial door thresholds for a number of applications such as fire-rated exits, handicap-accessible entryways, and more.


  • Emergency Exits

    If you use surface rod vertical exit devices, latching panic thresholds provide an area for the latch to fit into and a barrier to exterior elements while the door is closed. 

  • Noise

    Acoustic thresholds provide superb noise-canceling capabilities. Rooms with a large noise difference should use acoustic thresholds to cut down on sounds traveling between them.

  • Offsets

    Rooms with floors at different heights due to materials such as tile or carpet should use offset thresholds or half-saddle thresholds to provide a smooth transition between the two materials.

  • ADA Compliant

    A number of our ramp saddle thresholds are building code compliant according to the Americans with Disabilities Act (ADA). Ramp saddle thresholds are a great way to provide easy access to a raised threshold for wheelchair users or other mobility device users.

  • Material

    QualityDoor has a full catalog of heavy-duty thresholds made from a variety of materials like bronze, stainless steel, and anodized aluminum. We also carry thresholds made from vinyl or rubber for other types of applications.
