Traffic Door FAQ

Q. How do you measure a Traffic Door?

A. Under Traffic Door Basics see "How to Measure Your Opening"

Q. What is a Traffic Door?

A. A traffic door is a double acting door that provides a barrier between two areas. This "barrier" can be visual, thermal, or both. "Double Acting" means that the door swings in either direction. Traffic doors are designed to be opened by impact. The type of traffic, the impact and the function that the door is to serve will help you to determine the product to be used.

Q. Is there another name for a Traffic Door?

A. Yes, the most common names are listed below:
Impact Doors, Double Acting Doors, Bump Doors, Swinging Doors, Sheet Doors, Double Swinging Doors, Flexible Doors, Service Doors, and Industrial Doors

Q. How much is a Traffic Door?

A. Depending on the application, a traffic door for the same size opening can be as inexpensive as $200.00, or as high as $1,500.00.

Q. Why use a Traffic Door?

To increase productivity.
Double acting traffic doors allow you to speed the movement of your personnel or materials between two areas in your building by eliminating the stop, open, move through and manually close actions that a traditional single, one way swing door requires. Plus there are no door levers or knobs to turn. An impact traffic door opens easily in both directions, simply by pushing it open with your hand or impacted by a hand truck, pallet jack or even fork lift. After you pass through the opening, the swing door automatically returns to its closed position.

For visual separation, sound containment, safety and security.
You can use double acting traffic doors between the sales floor and store room, food prep to cold storage area, front office to the warehouse or customer seating area to the kitchen or in any opening where you need to hide the clutter or reduce the noise from your backroom operations. Having a double acting traffic door creates a physical and psychological barrier that will restrict access by customers, vendors or employees to your backroom areas. Security doors with steel window bars and locking systems are available for limited access areas.

Simple operation and environmental control will save you money everyday.
Doors that have electric, hydraulic or pneumatic operators that use electric energy to drive pumps and motors are more complex to install, require regular maintenance and can be costly to repair. Manually operated impact doors are less expensive than motorized alternatives, faster and easier to install, require less time and money to maintain or repair. A double acting traffic door with full perimeter door to jamb gasket seal and insulated panel will help control air, moisture, dust and dirt particulate movement through the opening. Automatic closing minimizes the time the door is open then seals and insulates to help maintain the temperature differential between two spaces. Controlling room to room temperature and humidity can increase HVAC system, cooler, freezer or refrigerated case efficiency which will save you energy dollars everyday.

Double acting impact traffic doors are your simple, cost-effective solution for efficient movement through any opening while maintaining a visual, sound and environmental barrier that provides energy savings everyday.

Q. What should I consider when I purchase a Traffic Door?

A. What is the opening Size? (Width and Height of Opening)

What type of traffic will be going through the door?

What is the opening size in relation to the product passing through the opening?

What is the traffic flow pattern going through the opening?

Will the door be subject to wash-down or chemicals?

Is the door being used for thermal separation?

What do you want the door to do?

  • control temperature?
  • visual barrier?
  • hold up under abusive applications?
  • provide a positive seal?

Q. Why does traffic flow matter?

A. The traffic flow pattern will:

  • Help determine the product to be used
  • Insures unimpeded travel
  • Insures that the installation is safe
  • Insures that the product will perform properly

Q. How wide of a load can go through the opening?

A. Rule of Thumb: An opening should be designed so that the maximum load that passes through the door is not more than 70% of the opening width.

Q. Are there options for when loads exceed 70% of the opening?

A. Yes, you can purchase a flexible traffic door, upgrade to a more durable door, provide swing limiting posts, or automate the door.

Q. What doors can motorized traffic go through?

A. Durulite Industrial Doors or our AirGard Flexible Doors.

Q. What are the jamb requirements?

A. Double Acting Doors are opened by "impact". Some of the force of this impact is transferred to the frame. The frame must be designed to accept this impact. Therefore, the following types of frames are available:

  • Hollow Metal - 1 Piece Welded (Reinforcement Recommended at Hinge Locations - 12" up and 12" down.)
  • Hollow Metal - K.D. - Not Recommended
  • Steel Channel Frames
  • Tube Steel Frames
  • Wood Frame
  • Concrete Block - Not Recommended

Q. What is a "Teardrop Bumper"?

A. Teardrop bumpers act as a "shock absorber" and protect the door panel from impact by forklifts, pallet jacks, and carts.

Q. What is the difference between a "C" hinge and "E" hinge?

A. The E-hinge provides a more finished look

Q. What is a Flexible Door?

A. A Flexible Door is a traffic door that utilizes a single hinge at the top of the door. The advantage that the flexible door offers is it's ability to handle abuse from traffic passing through the opening. There is no lower hinge on the door, and the panels will "flex" if wrapped around the corner, or if traffic passes partially through the opening and reverses direction.

Q. What are advantages to Flexible Doors?

A. Flexible doors allow loads nearly as wide as the opening to pass through the opening.

  • Flexible doors have a "gravity return" hardware which is simple, durable and effective.
  • They will accept a tremendous amount of abuse.
  • A flexible panel can be "wrapped" around the frame without damage.

Q. What are disadvantages to Flexible Doors?

A. Flexible doors offer limited draft resistance, door will blow open if negative or positive pressure exists.

  • Offers very little to no thermal insulation
  • Requires rigid protective impact plates if sharp objects pass through the opening, therefore making a flexible door rigid
  • Gravity hardware rises when open, must use caution regarding jamb thickness and overhead obstructions.

Q. How big should the rough opening be when using KD frames?

A. 4-1/2" wider and 2-3/8" higher than the finished opening.
