Woodfold Accordion Doors FAQs

Q: How do I measure finished openings?
A: To make sure that you get your Woodfold accordion door in the correct size, the finished opening should be measured. The ordered size should be the size after every modification has been done that will ever be done to it. Measure the exact side to side dimension and exact height from header surface (where track attaches) to final finished floor or counter surface. Dimensions are defined width first and then height.
Q: How much do Woodfold accordion doors weigh?
A: Depending on the door Series, weights, according to the factory, are:

Series 140, 220, 240

  • 6-8 height 10 lbs per lineal foot
  • 8-0 height 12 lbs per lineal foot

Series 440, 540, 2100

  • 10-0 height 15 lbs per lineal foot
  • 12-0 height 18 lbs per lineal foot

Series 3300

  • 8-0 height 26 lbs per lineal foot
  • 10-0 height 32 lbs per lineal foot
  • 12-0 height 38 lbs per lineal foot
Q: What is the “best” shipping schedule?
A: Woodfold’s normal production cycle is two to three weeks. That is for manufacturing time for up to 250 lineal feet of door, for all door Series for standard finishes. Time in transit will average five to ten days from the U.S. West Coast to the East Coast. Additional shipping times apply for Alaska, Canada, Hawaii and other offshore destinations.
Q: What is the Woodfold doors warranty?
A: By using the continuous pin hinge hardware system, the two vulnerable areas found in traditional accordion doors, the outside fold and the roller system, have been virtually eliminated.The vinyl panel connector used at the outside fold will be prevented from cracking or checking. The metal shank of the top roller system is riveted to the upper metal continuous pin hinge hardware system, instead of being fastened into the core of the body panel.

Because of these design features, if any of the following situations occur under normal circumstances, we would, upon return of the door, repair it or replace it.

  • The vinyl panel connectors crack or check.
  • The rollers break out.
  • The body panels delaminate.

There is no warranty regarding installation repair, re-installation, labor or transportation because we have no control over those. Doors that are unfinished do not have a warranty.

Q: Why do Series 140 & 240 closet doors need to be “handed”?
A: The 140 and 240 Series closet doors are intended for use where a utility grade or unfinished back surface is acceptable, as in closet openings. The handing, either stacks left or stacks right, faces this unfinished side to the inside of the closet.
Q: How does “curved” radius track work? How are they installed?
A: Woodfold uses an I-beam track, that looks similar to the cross section of a railroad track, of aluminum for curved installations . The I-beam configuration allows shaping on the job site to a minimum radius to 12″. That allows Woodfold doors to follow a curved path when it’s installed. The I-beam style track hangs from clips attached by “W” screws to the header above.
Q: What is a stack left? What is a stack right? What is a right-hand door? What is a left-hand door?
A: As you face the door from the front of it, stack left or left-hand would stack and be affixed to the wall or the jamb on your left. Stack right or right-hand would be stacked or affixed to the wall or jamb on your right.
Q: What is “hat channel”? Where does it mount?
A: Aluminum hat channel is used for acoustic ceiling tile systems, for 2′ x 4′ tiles that drop in. The hat channel allows the ceiling contractor to preinstall a slot for the track. The hat channel is incorporated into the ceiling grid system. The ceiling tiles actually rest on the outer flange. Hat channel got it’s name because it looks like a top hat in cross section.When measuring for doors that use hat channel, the finished opening dimension is measured from the surface that the hat channel attaches to, to the finished floor. It’s not measured from the finished surface of the acoustic ceiling.

Q: What is a sliding jamb option?
A: Sliding jamb options are commonly used for large doors that when stacked will occupy three or four feet of space. They allow larger doors to be stored in a pocket constructed on the job site. By using the sliding jamb option, less lineal feet of folding door needs to be purchased and it is stored in its protective closet, when not in use.
Q: How do I specify two doors that meet in the middle?
A: We would call this “a pair”. A “standard pair” would have 2 doors that meet exactly in the middle, i.e., a 12’0″ pair would have two 6’0″ door leaves, one stacking left and one stacking right. These are also available in uneven pairs, where the door on one side is longer than the door on the other side.
Q: Can I install my door directly to my suspended ceiling? If not, what do I need to do for support?
A: If a suspended ceiling system is being installed with the door, a recessed “hat channel” can be used for the door installation.If a suspended ceiling is already in place, a common method to install the door is to place a finished board, e.g., 1″ x 6″ on the underside, or room side, of the ceiling and a similar board above the ceiling. These would be fastened to each other, forming a sandwich with the acoustic ceiling material between.

Drop wires or rods would be attached from above to support the door and plates. The track would then be attached to the exposed board. This method will change the finished opening dimensions.

Q: What is a pair?
A: Two door sections manufactured to meet and split an opening. When ordering pairs of doors provide the total opening width and specify “pair.” In this instance you’ll receive a matched unit with a door leaf stacking either way in mirror image. Do not order two separate doors, one left and one right.
Q: What are the requirements for the header to handle the weight of the door?
A: Headers should be fabricated to span the entire opening without sagging. Folding door track must be plumb and level for the door to operate properly. In consideration of various building code and structural requirements we suggest that structural and design requirements for support be addressed locally.
Q: How do I install the doors in the opening?
A: Woodfold doors are top suspended with no floor track or clips required. Track will be attached to the header with screws provided. Complete installation instructions are provided with each door.
Q: Is my door repairable in the field?
A: Some repairs are easily accomplished in the field. Others require specialized tooling with equipment available only at the Woodfold factory. For specific repair questions please contact Woodfold.
Q: Can I paint the door?
A: Vinyl lam doors and hardwood veneer doors are not suitable for painting in the field. If you want to paint a Woodfold door, we suggest that you specify our paint grade MDF material or better yet allow Woodfold to custom paint or stain the door to match your finish requirements. Please note that unfinished doors carry no warranty.
Q: I’ve changed my mind on the color. Can I paint over the door panels?
A: Woodfold doors are typically faced in vinyl lam or hardwood veneers with a lacquer topcoat. Vinyl lam panels cannot be painted. Hardwoods, if hand sanded lightly, may be able to be painted or restained in the field. Extreme care must be taken not to get any finishing materials on the panel connectors or into the saw kerfs. Any refinishing in the field would void Woodfold’s warranty.
Q: Can I exchange or return my door?
A: Every Woodfold door is custom made to size and as such is not returnable.
Q: How do I shorten a Woodfold door?
A: Woodfold 140/220, 240 Series doors can be shortened in the field. 440, 540, and 2100 Series doors cannot be shortened in the field. 3300 Series doors cannot be shortened at all. Specific instructions are available upon request.
Q: What latch/lock options are available?
A: Woodfold’s 140 and 220 Series doors feature a magnetic catch as standard. No other lock or latch options are available. Woodfold’s 240, 440, 2100 and 3300 Series doors feature a latch two sides with dead latch as standard. Latch one side or a magnet are available at no additional charge. Key lock options are available at additional cost.
Q: Do you make sound doors?
A: Woodfold offers two acoustically rated doors, the 2100 Series door which provides a minimum level of sound control for a modest cost and our 3300 Series door which is considered mid-level sound control.
Q: Do Woodfold doors fold flat?
A: No. By design an accordion folding door is intended to have adjacent panels at a slight angle (it depends on the fullness of the door within the opening). If they folded flat the stacking action would be lost.
Q: Can your doors be used on the exterior of a building?
A: Woodfold doors are intended for interior applications only.
Q: Are Woodfold doors reversible?
A: Our 220 Series, 240 Series, 440 and 540 Series, 2100 and 3300 Series doors are reversible and may be stacked left or right. This may change the jamb/mounting panel direction or may require reversing the lock/latching mechanism. The 140 and 240 Series closet grade doors are not reversible because the backside is utility grade.
Q: What is your heaviest duty door?
A: All Woodfold doors are fabricated with 4-1/4″ x 1/4″ body panels featuring a steel hardware hinge system, top and bottom. The 240 Series door is used in numerous commercial installations including restaurants, conference rooms and industrial settings.
Q: Can I get a 140 Series door finished on both sides?
A: No. The Woodfold 140 Series door features utility grade or unfinished back at Plant option. For a door good on both sides use Series 220 or 240.
Q: What is an intermediate post? Why use it?
A: An intermediate rolling post serves several functions. For extremely large doors the intermediate post allows the door to be fabricated, shipped and subsequently installed in two sections which are then bolted together in the field.This allows easier handling for movement of the door into the building, up stairs, etc. Additionally, use of an intermediate post allows two doors to be joined together to form a T.

The intermediate rolling post will have an interlocking jamb molding affixed to it to accept the second door. Also on larger openings the intermediate post provides a mounting point for foot bolts most commonly used to add security and stability to the door.

Q: Can you key the door to my system?
A: Woodfold’s Adams-Wright lock system is provided standard with a Weiser cylinder. Most commercially available lock cylinders can be installed in the Adams-Wright unit in the field by a qualified locksmith. Woodfold also offers master and custom keying at the time of manufacture.
Q: Can you have one color vinyl on one side of the door and another color of vinyl on the other side of the door?
A: No. Woodfold receives their vinyl lam material pre-applied from the panel supplier. This assures you of the highest quality and best lamination technology available. For multi-colored doors we do offer custom paint or stain services.
Q: Does the door get fastened at the bottom as well as the top?
A: No. Woodfold doors are top suspended only.
Q: If we forgot to mention that we were going to have carpeting and we already have the door, what can we do to shorten the door?
A: Woodfold 140/220, 240 Series doors can be shortened in the field. 440, 540, and 2100 Series doors cannot be shortened in the field. 3300 Series doors cannot be shortened at all. Specific instructions are available upon request.
Q: Do I make any deductions for actual door size?
A: Fabrication dimensions required by Woodfold call for final exact finish openings. Do not deduct from this finished opening size. However, for floor clearances other than the standard 5/8″ nominal clearance you can specify the clearance you want. For instance, 5’0″ wide x 6’8″ high with 1″ floor clearance. For 2100 and 3300 Series doors specify exact finished opening size only.
Q: What is the maximum length per piece for track?
A: Woodfold track is extruded in 12′ lengths. Actual track lengths provided with doors are based on a number of factors. In some instances the track is shipped packed separately or the track may also be packed within the door crate. In the event of multiple pieces of track for a single door the track profile provides for splice pins.
Q: What size doors are available from Woodfold?
A: Woodfold’s 140 and 220 Series doors are available to fit maximum widths of 8’0″ and heights of 8’1″. Our 440 and 540 Series doors are available in any width and in heights to 10’1″. Our 240, 2100, and 3300 Series doors are available in any width and in heights up to 12’1″. In above sizes vinyl lam doors are available in finished opening heights to 12’1″, hardwoods are limited to 10’1″ finished opening heights.

A: Woodfold offers doors fabricated of Class I fire retardant body panel material. This rating applies to the medium density fiberboard (MDF) body panel core only and does not apply to the door as a unit.
Q: Can a Woodfold door be installed outdoors?
A: Woodfold doors are designed and constructed for interior applications only. Exposure to the elements including moisture, extreme cold, and extreme heat may effect the operation and long term durability of your Woodfold door.
