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

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?
A. Traffic doors are an excellent choice for applications where a high volume of traffic exists and minimal infiltration is desired. Doors serve as a barrier. This barrier can be thermal, visual, sound, environmental, or secure.

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.

 

FIRE AND SERVICE SLIDING DOORS

 

Q. What does egress mean?
A. The ability to exit an opening

Q. What does entrapment mean?
A. In relation to sliding doors, it is the ability to "move" a closed or stopped door in order to exit the area in an emergency.

Q. What is the difference between a Pharmaceutical door and a Clean Room door?
A. A pharmaceutical door is a title given to a wide range of doors used in specific chemical production rooms. Construction for ease of cleaning and a wide range of material used. (Saino type) Cleanroom doors are not generally used in wash down areas or those with a high bacterial rate. They are aluminum stile and rail type construction. (Non Saino Type).

Q. What is the difference between the 1000 & 2000 series sliding fire door?
A. The core, the 1000 series door has a honeycomb core & the 2000 series door has a calcium silicate core which, gives you a 250 degree 30 minute temperature rise.

Q. What is the difference between the 1000 & 3000 series sliding fire door?
A. The track, the 1000 series door has box track hardware & the 3000 series door has our easy roller hardware.

Q. What is your most economical fire door?
A. The 1000 series fire door

Q. What is the voltage requirement for you sliding operators?
A. 120-volt single phase, 24-volt control circuits, and minimum 10-amp circuit.

Q. Do you have sliding fire doors for clean room applications?
A. Yes, our 50000 series sliding door is a casing mounted fire door that can be used in clean room application. (Stainless steel fire doors are available)

Q. Are the casing mounted doors clean room rated?
A. No, however we believe the doors will meet class 100,000 rating.

Q. Are any of the doors sound rated?
A. No, however the use of mineral wool core and weather-stripping works automatically to reduce the infiltration of sound.

Q. Do we manufacture sliding fire rated cooler / freezer doors?
A. No, however we can provide a cooler / freezer door and we can provide a separate fire door.

Q. Do we manufacture fire rated impact doors?
A. No, impact doors do not latch therefore can not be a labeled product.
