Series 3300: Economical Acoustic Partitions


Woodfold’s Series 3300 reduces distracting noise by using an acoustic lining and a perimeter seal. With an exclusive heavy-duty hardware system, this dual-walled partition is as at home in offices or religious facilities as it is in restaurants or hotel meeting spaces needing effective sound control. Series 3300 doors are available in a variety of attractive hardwood and Vinyl-Lam finishes, and can be ordered with differing finish materials on each door face.
