SEALED ACOUSTICAL FOLDING DOORS

SEALED ACOUSTICAL FOLDING DOORS-SERIES 3300

Sealed acoustical folding doors are a uniquely practical solution for space, sound and heat loss control. Woodfold’s acoustic room partitions are a smart alternative to similar, but much more expensive options. They are perimeter sealed, acoustically lined and incorporate an exclusive heavy-duty hardware system. This dual walled partition functions beautifully in offices, churches, restaurants and hotel meeting spaces or any application that requires sound control.

Our sound partition has an FSTC 33 rating and offers an excellent alternative to all other available products. Accordion room dividers are available in a variety of handsome hardwood and vinyl laminate finishes that can be fabricated with alternate finish materials on each door face. Please see our “Finishes & Colors” page.

This product also meets ADA compatibility standards.
