1. How do I measure finished openings for accordian doors?
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.
2. How much do Woodfold accordion doors weigh?
Depending on the Series, weights are as follows:
Series 140, 220, 240 Accordian Doors
• 6-8 height 10 lbs per lineal foot
• 8-0 height 12 lbs per lineal foot
Series 440, 540, 2100 Accordian doors
• 10-0 height 15 lbs per lineal foot
• 12-0 height 18 lbs per lineal foot
Series 3300 Accordian Doors
• 8-0 height 26 lbs per lineal foot
• 10-0 height 32 lbs per lineal foot
• 12-0 height 38 lbs per lineal foot
3. What is the "best" shipping schedule?
Woodfold's normal production cycle (manufacturing time [up to 250 lineal feet]
for all Series in our standard finishes) is two to three weeks. Additional time may
apply for custom decorative doors. 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.
4. What is the warranty of Woodfold accordion doors?
By use of our continuous pin hinge hardware system, we have virtually eliminated
the two vulnerable areas found in traditional accordion doors. These are the outside
fold and the roller system.
This hardware system will prevent the vinyl panel connector used at the outside
fold from cracking or checking. Also, rather than being fastened into the core
of the body panel, the metal shank of the top roller system is riveted to the
upper metal continuous pin hinge hardware system.
Therefore, under normal circumstances, if any of the following situations occur in a
Woodfold accordion door, 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.
We do not have a warranty regarding installation repair, re-installation, labor
or transportation. Unfinished accordian doors do not have a warranty.
5. Why do Series 140 & 240 closet doors need to be handed?
The 140 and 240 Series accordian doors are intended for use in closet openings
where a utility grade or unfinished back surface is acceptable. The handing, either
stacks left or stacks right, orients this utility side to the inside of the closet.
6. How does "curved" radius track work/install?
For curved installations Woodfold uses an I-beam style track (similar to railroad
track) of aluminum. The I-beam configuration allows job site shaping to a minimum
radius to 12" allowing Woodfold doors to follow the required path at the job site.
The I-beam style track hangs from clips attached by "w" screws to the
header.
7. What is a stack left? What is a stack right? What is a right-hand
door? What is a left-hand door?
As you face the accordion door from the primary side, stack left or left-hand accordian doors would
stack and be affixed to the wall/jamb on your left. Stack right or right-hand accordian doors
would be stacked/affixed to the wall/jamb on your right.
8. What is hat channel and where does it mount?
Aluminum hat channel is used for acoustic (2' x 4') drop in ceiling tile systems.
The hat channel allows the ceiling contractor to preinstall a slot for the track
and incorporate the hat channel into the ceiling grid system. The ceiling tiles
actually rest on the flange. Hat channel looks like "a top hat" hence the name.
When measuring for accordion doors utilizing hat channel the finished opening dimension
should measure from the surface to which the hat channel attaches to the finished
floor rather than from the finished surface of the acoustic ceiling.
9. What is a sliding jamb?
Sliding jamb options allow larger accordian doors to be stored in a pocket constructed
on the job site. They are commonly used for larger accordian doors that when stacked will
occupy three or four feet of space. By utilizing the sliding jamb option less
lineal footage of folding door needs to be purchased and, when not in use, it
is stored in its protective closet.
10. How do I specify two accordian doors that meet in the middle?
We would identify this as a pair. A standard pair would 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. Also, available would be uneven pairs, i.e., 12'0" wide
with 9' left, and 3' right.
11. Can I install my accordion door directly to my suspended ceiling?
If not, what do I need to do for support?
If the suspended ceiling system is being installed in conjunction with the
accordion door, our recessed hat channel can be used to facilitate installation. If suspended
type ceiling is already in place a common method of installation is to place a
finished board (1" x 6") on the underside/room side of the ceiling and a similar
board above. These would be fastened together forming a sandwich with the acoustic
material between. Drop wires or rods would be installed from above to support
the door and plates. The track will subsequently be attached to the exposed board.
Please note, this will change the finished opening dimensions.
12. What is a pair?
Two door sections manufactured to meet and split an opening. When ordering
pairs of accordian 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 accordian doors, one left and one right.
13. What are the requirements for the header to handle the weight
of the door?
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.
14. How do I install the accordian doors in the opening?
Woodfold accordian 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.

15. Is my accordion door repairable in the field?
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.
16. Can I paint my accordion door?
Vinyl lam doors and hardwood veneer accordian doors are not suitable for painting in
the field. If you want to paint a Woodfold accordion 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, or to create custom decorative doors.
Please note that unfinished accordion doors carry no warranty.
17. I've changed my mind on the color. Can I paint over the
door panels?
Woodfold accordian 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.
18. Can I exchange or return my door?
Every Woodfold accordion door is custom made to size and as such is not returnable.
19. How do I shorten a Woodfold accordion door?
Woodfold 140/220, 240 Series accordian doors can be shortened in the field. 440, 540,
and 2100 Series accordian doors cannot be shortened in the field. 3300 Series accordian doors cannot
be shortened at all. Specific instructions are available upon request.
20. What latch/lock options are available for your accordian doors?
Woodfold's 140 and 220 Series accordian doors feature a magnetic catch as standard.
No other lock or latch options are available. Woodfold's 240, 440, 2100 and 3300
Series accordian 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.
21. Do you make sound doors?
Woodfold offers two acoustically rated doors, the 2100 Series accordion door which
provides a minimum level of sound control for a modest cost and our 3300 Series
accordion door which is considered mid-level sound control.
22. Do Woodfold accordian doors fold flat?
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.
23. Can your accordian doors be used on the exterior of a building?
Woodfold accordian doors are intended for interior applications only.
24. Are Woodfold accordian doors reversible?
Our 220 Series, 240 Series, 440 and 540 Series, 2100 and 3300 Series accordian 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 accordian doors are not reversible because the backside is utility
grade.
25. What is your heaviest duty accordion door?
All Woodfold accordian doors are fabricated with 4-1/4" x 1/4" body panels
featuring a steel hardware hinge system, top and bottom. The 240 Series accordion door is
used in numerous commercial installations including restaurants, conference rooms
and industrial settings.
26. Can I get a 140 Series accordion door finished on both sides?
No. The Woodfold 140 Series accordian doors features utility grade or unfinished back
at Plant option. For an accordion door good on both sides use Series 220 or 240.
27. What is an intermediate post? Why use it?
An intermediate rolling post serves several functions. For extremely large
accordian 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 accordian door into the building, up stairs, etc. Additionally,
use of an intermediate post allows two accordian 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.
28. Can you key the accordion door to my system?
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.
29. Can you have one color vinyl on one side of the door and
another color of vinyl on the other side of the door?
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 accordian doors we do offer custom paint or stain services.
30. Does the door get fastened at the bottom as well as the
top?
No. Woodfold accordian doors are top suspended only.
31. 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?
Woodfold 140/220, 240 Series accordian doors can be shortened in the field. 440, 540,
and 2100 Series accordian doors cannot be shortened in the field. 3300 Series accordian doors cannot
be shortened at all. Specific instructions are available upon request.
32. Do I make any deductions for actual door size?
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 accordian doors specify exact finished opening size only.
33. What is the maximum length per piece for track?
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 accordion door the track profile provides
for splice pins.
34. What size accordian doors are available from Woodfold?
Woodfold's 140 and 220 Series accordian doors are available to fit maximum widths of
8'0" and heights of 8'1". Our 440 and 540 Series accordian doors are available in any width
and in heights to 10'1". Our 240, 2100, and 3300 Series accordian 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.
35. Do you make fire doors?
Woodfold offers accordian 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.
36. Can Woodfold accordian doors be installed outdoors?
Woodfold accordian 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 accordion door.
37. If I don't like plain wood panels on my accordian doors what other type of decoration is available?
You can add a mural, a logo, or even textured glass or laser-cut panels to your accordian doors.
See our decorative doors page for photos and more information.
38. Is it "accordion" or "accordian"?
The correct spelling is "accordion" with the letter O, but a majority of people searching online spell it accordian door rather than accordion door so we've tried to use both spellings in this document.
