Series 3300: Acoustic Accordion Doors

You could pay more for an acoustic room partition, but you don’t have to: 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. Find the perfect one under the Decorative Options and Color & Wood Selector tabs.

A Bevy of Beauties

Laminates are especially good for installations demanding durable
and easy-to-maintain (and clean) partitions: hospitals, laboratories,
and restaurants are some examples. Our custom service opens up
a world beyond standard decorator colors, to include a wide
selection of high-pressure decorative laminates you can specify for
any Woodfold Accordion Door. If you’ve found a laminate from any
nationally recognized brand, tell us the manufacturer’s name and
pattern number and we’ll make the door for you. How easy is that?
Put a Bird on It

When you want to brandish your brand, consider a custom
designed and applied logo, trademark, or corporate image on your
Woodfold accordion door. Or maybe you want a scenic alpine
meadow for a restaurant divider, or a soothing, subtle pattern?
Decorative murals are a great option for commercial or residential
room dividers. For the best reproduction possible, please provide
us with high-quality artwork for your mural. Contact your distributor
or call Woodfold at 503.357.7181 for details about acceptable file
formats. For sample murals, or to use your own image, please visit
Murals Your Way
Are shag walls back, yet?

They could be, if you want to make that statement. Our flexible
custom service can help you match or complement interior walls,
using wall covering material you specify for your Woodfold
Accordion Doors. For additional information on wall coverings,
contact your distributor or call us directly at 503.357.7181.
Wooden it be nice?

We offer stunning hardwood veneers in birch, maple, oak, cherry,
mahogany, walnut, and alder for our Accordion Doors, to suit
almost any installation. But if your order calls for something a little
more upscale—something unique—Woodfold also makes a variety
of exotic and special hardwood veneers. Contact your distributor or
call us directly at 503.357.7181 for further details.

Decorative Options

PLEASE NOTE: The stain and color samples on this page have been color matched using a monitor calibrated to the sRGB IEC1966-2.1 color
profile. Intended only as a guide for color selection, the actual finish materials will vary due to the natural and acceptable variations in wood
grain characteristics, textures, and color tones, as well as the color variation that occurs among individual computer monitors. If color, grain,
or tone match is critical, please see an actual color selection chip or refer to Woodfold's custom finish service by contacting your local
distributor.

*All panel samples show factory default color combinations, unless noted otherwise.
We’ve got today’s most popular hardwood species to match your interiors. Woodfold insists on select grade veneers, laminated to an
engineered core to ensure excellent dimensional stability. Clear finish is standard; however, custom-stained finish service is always available.
Please supply a physical color sample for matching.

Project Type: Executive Office

Problem: Merging a relaxed, open-door management style with a periodic need for privacy and quiet.

Solution/Description of the Installation: By combining Woodfold’s Series 440/540 Visifold see-through doors with hardwood panels, the office designer was able to create the inviting sense of openness his executive client requested, but still provide private spaces when needed. Installation on a curved track added to the office’s architectural interest.
