Frequently Asked Questions

Q: What sizes of Accordion Doors do you offer?

A: Our selection is unbeatable! Woodfold Series 140 and 220 doors fit maximum widths of 8' 0" and heights of 8' 1". Our Series 440 and 540 doors are available in any width and in heights to 10' 1". Our Series 240, 2100 and 3300 doors are available in any width and in heights up to 12' 1". All series of Vinyl Lam doors are available in finished opening heights to 12' 1", while hardwood doors are limited to 10' 1" in height.

Q: How do I measure openings for a Woodfold Accordion Door?

A: To assure correct sizing of your door, the finished opening must be measured precisely from side to side for width and from the header surface where the track will be attached to the finished floor or counter surface for height. When ordering, please first note the width first and then the height.

Q: When measuring for a Woodfold Accordion Door, do I make any deductions for actual door size?

A: We need precise measurements to begin fabrication, so don’t deduct from your finish opening size. You may, however, specify a floor clearance other than the standard 5/8” if you prefer. (For Series 2100 and 3300 doors, specify exact finished opening size only.)

Q: How is an Accordion Door installed?

A: It’s relatively simple, since Woodfold doors are top-suspended, without the need for floor tracks or clips.
Of course, complete installation instructions are provided with each door, but if you’d like a quick overview of how to install a Woodfold Accordion Door, click here.

Q: What type of header is needed to handle the weight of a Woodfold Accordion door?

A: Headers must span the entire opening without sagging,
since the folding door track must be plumb and level in order for the door to operate properly. Local building codes vary widely, so we recommend that you check into structural and design requirements for your area.

Q: What type of Warranty do you offer?

A: Under normal circumstances, Woodfold will repair or replace any door returned to us if:

  • Vinyl panel connectors crack or check
  • Rollers break
  • body panels delaminate

Fortunately, our unique continuous pin hinge hardware system virtually eliminates the two most vulnerable areas in most accordion doors – the outside fold and the roller system.

Our system, unlike most, prevents the vinyl panel connector used at the outside fold from cracking or checking. Our rollers also provide more durable performance, since rather than being fastened into the core of the body panel, the metal shank of the top roller system is riveted to the upper pin hinge hardware system. Our warranty does not cover installation repair, re-installation, labor or transportation, nor unfinished Accordion Doors.

Q: How do I clean my Woodfold Accordion Door?

A: For regular cleaning of the Vinyl/Acrylic/Aluminum/Veneer - use mild soapy water then dry with a soft cloth or chamois. Do NOT use household cleaners, abrasive towels or scouring pads. click here for more information

Q: How quickly can I get a Woodfold Accordion Door?

A: Here at Woodfold, we're noted not merely for our quality, but our speed. Our normal production cycle for all standard-finished doors up to 250 lineal feet in size is two to three weeks. Shipping time averages five to ten days from West Coast to East Coast, with additional transit time required for shipments to Alaska, Canada, Hawaii and other offshore destinations.

Q: What does "stack left" and "stack right" mean?

A: As you face the door, a stack left or left-hand door would be affixed (or “stacked”) to the wall jamb on your left. A stack right or right-hand door would be affixed to the right.

Q: Why do Series 140 and 240 closet doors need to be handed?

A: Our Series 140 and 240 closet doors are intended for use in openings where a utility-grade or unfinished back surface is acceptable. The handing, either stacked left or right, assures that the utility side will be oriented to the inside of the closet.

Q: How does your curved radius track work, and how is it installed?

A: For curved installations, Woodfold utilizes an aluminum I-beam style track hanging from clips attached to the header. This configuration allows for on-site shaping to a minimum radius of 12”, enabling the door to follow the required path.

Q: Explain the term "hat channel."

A: Aluminum hat channel is used for 2’ x 4’ acoustic drop in ceiling tile systems, allowing the contractor to pre-install a flange for the track and incorporate the hat channel into the ceiling grid system. The ceiling tiles actually rest on this flange.

When measuring for doors utilizing hat channel, the finished opening dimension should reflect the distance from the surface to which the hat channel attaches to the finished floor rather than from the finished surface of the acoustic ceiling.

Why the strange term? Hat channel looks like a top hat, hence the name.

Q: What is a sliding jamb?

A: Sliding jambs, commonly used for large doors which when stacked will occupy three or four feet of space, enable such doors to be stored in a protective pocket constructed on-site. A sliding jamb requires less lineal footage of folding door to be purchased.

Q: How do I specify two doors which close together?

A: Accordion doors that meet and split an opening are considered a pair. A standard pair would meet exactly in the middle – a 12’ pair, for example, would consist of two 6’ doors, one stacking left, the other stacking right. We can also craft uneven pairs – a 9’ door stacking left and a 3’ door stacking right in a 12’ opening.

When ordering a pair of doors, provide the total opening width and specify “pair.” You’ll receive a matched unit, one stacked right and one stacked left. Do not order separate right- and left-hand doors.

Q: Can a Woodfold Accordion Door be installed directly to a suspended ceiling? If not what kind of support is required?

A: If a suspended ceiling system is being installed in conjunction with an Accordion Door, use of a recessed hat channel will simplify the job. If the ceiling is already in place, the most common practice is to place a finished 1” x 6” board on the underside, or room-side, of the ceiling and another board on the topside of the ceiling. Fastened together, these will form a sandwich of sorts, with the acoustic material in between. Drop wires or rods installed from above will support the door and plates, and the track can then be attached to the underside board. It’s important to note that finished opening dimensions will be affected, so measure carefully.

Q: Can a Woodfold Accordion Door be repaired once it's installed?

A: While some repairs are easily accomplished on-site, others may require specialized tooling available only at our factory. Should a repair ever be needed, we’d suggest that you contact us for specific advice.

Q: Can a Woodfold Accordion Door be painted on-site?

A: Yes, but we strongly suggest that you specify a door crafted of our paint-grade MDF material. Better yet, since unfinished doors aren’t covered by warranty, have your door custom painted or stained by the experts at Woodfold. Our Vinyl Lam  Accordion Doors are not suitable for on-site painting.

Q: If I change my mind about color, can I repaint an Accordion Door?

A: Our hardwood veneer Accordion Doors may, if lightly hand-sanded, be repainted or restained on-site, although extreme care must be taken not to get finishing materials on panel connectors or into saw kerfs. Our Vinyl Lam doors cannot be painted, and refinishing of any Woodfold Accordion Door will void its warranty.

Q: Can I order a door with two different colors of vinyl, front and back?

A: Sorry, no, but for good reason. We craft our Vinyl Lam Accordion Doors with materials pre-applied by our panel supplier in order to ensure the highest quality lamination technology available. If you’re looking for multi-colored doors, we suggest you consider our custom paint or stain services.

Q: Can I exchange or return my door?

A: Sorry, but every Woodfold Accordion Door is custom-made to size and cannot be returned. Besides, it’s highly unlikely you’d want to!

Q: Is it possible to shorten a Woodfold door?

A: Our Series 140, 220 and 240 Accordion Doors can be shortened on-site, while Series 440, 540, 2100 and 3300 cannot. For details or instructions, contact us.

Q: What type of latch and lock options are available?

A: Depends on the door you order. Woodfold Series 140 and 220 come standard with a magnetic catch. Woodfold Series 240, 440, 2100 and 3300 feature a two-sided dead latch, with a one-sided latch or magnetic catch available at no cost. Key lock options are also available.

Q: If I order a door with a key lock, can it be made compatible with my other locks?

A: You bet. Woodfold’s Adams-Wright lock system is compatible with most commercially available lock cylinders and can be keyed in the field by a qualified locksmith. We can also provide master and custom keying when we manufacture your door.

Q: Are Woodfold Accordion Doors sound rated?

A: Two of our doors are sound rated – the Series 2100, which provides a minimum level of sound control at a very affordable price, and our Series 3300 door, offering mid-level sound control.

Q: Do you offer fire-rated doors?

A: Woodfold doors have the option to be fabricated of Class I fire retardant medium density fiberboard. Note: this rating applies to the body panel core only and does not apply to the door as a unit. Fire core is only available in Chalk and Light Oak finishes

Q: Do your Accordion Doors fold perfectly flat?

A: In order to ensure proper stacking action, Woodfold Accordion Doors are designed to fold with adjacent panels at a slight angle, depending on the fullness of the door within the opening.

Q: Can your Accordion Door be used outside?

A: No, Woodfold doors are intended for interior applications only, since exposure to moisture or extreme temperatures may affect their operation and durability.

Q: What door works best in heavy duty installations?

A: Woodfold’s Series 240 Accordion Door is a popular choice, especially for high-use installations in restaurants, conference rooms and industrial settings. However, all of our Accordion Doors offer long-life durability, crafted with 4¼” x ¼” body panels and a super-strong steel hardware hinge system.

Q: What is the difference between a Woodfold Series 140 door and a Series 220 or 240?

A: Since our Series 140 Accordion Door is intended for closet use, it has a utility grade or unfinished back. Series 220 and 240 doors are finished on both sides.

Q: What is an intermediate rolling post and when is it needed?

A: An intermediate rolling post serves several functions. It enables an extremely large door to be fabricated, shipped and installed in two sections, for easier handling. Constructed with an interlocking jamb molding, the intermediate rolling post enables two doors to be joined together to form a “T,” desired in some settings, and also adds stability and security for doors spanning larger openings.

Q: What is the maximum length per piece of track?

A: Woodfold track comes in 12’ lengths. For wider openings, multiple pieces of track for each door are connected with splice pins. Depending on the number of tracks required, they’re either packed within the door crate, or shipped separately.

Q: How do I measure finished openings?

A: To assure correct sizing of your Woodfold accordion door the finished opening should be measured exact side to side dimension and exact height from header surface (where track attaches) to final finished floor or counter surface. This dimension should be stated width first and then height and should represent sizes after everything has been done to the opening that will ever be done to it.
