SERIES 3300 ACOUSTICAL
ACCORDION DOORS

Woodfold’s Series 3300 Accordion Door combines the proven durability of their exclusive hardware hinge system, rigid MDF body panels and sound liner to create a dual walled sound partition (FSTC 33/Field) that offers an excellent alternative to other available products.

Practical applications for the Series 3300 include offices, churches and restaurants where moderate sound control is desired, along with the flexibility and convenience of an accordion style partition featuring solid panels.

Sound rated accordion doors can also provide improved speech privacy between adjacent rooms. The Woodfold Series 3300 (FSTC 33/Field) door has been evaluated for speech privacy between adjacent classrooms by an independent acoustical consultant using the Articulation Index method described in ANSI S3.5-1969. The results of this analysis reveal that excellent speech privacy can be achieved with this product when the speaker in the adjacent room is speaking in a normal voice level.
