The H4100 acoustic accordion partitions consist of two continuous laminated vinyl covers assembled to steel pantographs supported by aluminum covered steel channel posts at each end with an STC 41*. This series also incorporates steel strips laminated within each fold for enhanced acoustical performance. These acoustic partitions are easy to operate, durable and come in a wide variety of options and finishes.

Woodfold’s continuous vinyl design accordion partitions are custom designed and manufactured to suit the specific needs of your space.
Two laminated covers with clean, crisp lines, multi-ply soft vinyl sweepstrip sound seals at the top and bottom of both sides. The laminated construction ensures the covers will not sag or bag over time.

Customers can choose vinyl from either the Woodfold Vinyl collection or the Moderco Vinyl collection. Both options are detailed below.
To assure correct sizing of your Woodfold accordion door the finished opening should 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.
Width Measure the width at the bottom, halfway up and at the top of the door and use the widest dimension you have. Note: if the widest dimension is at the bottom or center you may have to trim the suspension track to fit your opening at the top of the door as track lengths are made to the ordering width. This can be done with a hacksaw.
Height Measure from the top of the finished floor to the point where you are going to attach the track. NOTE: For those areas where the floor is uneven (e.g. concrete floors) please take 3 or 4 height measurements along the floor. Use the shortest measurement as the finished opening height except 2100, 3300 or 4100. For sound doors use tallest height.
Dimensions should be stated width first and then height and should represent sizes after any and all modifications have been done to the opening. Unless customer specified, we will allow 9/16″ floor clearance for doors over 4′ high and 5/16″ for doors 4′ and less. Beware of variations in floor and/or ceiling surfaces.
Please check your measurements for accuracy. Contact us if you need additional assistance.
