Acousti-Seal® Single Panel Systems

Modernfold Single Panel Systems provide the ultimate in versatility and flexibility, allowing for capabilities such as multiple room setups and changes in the location of pass doors and work surfaces. Modernfold offers three products under the Acousti-Seal Single Panel Model:

Acousti-Seal® Encore®

When top-of-the-line acoustic performance and premium aesthetics are desired. Acousti-Seal® Encore® raises the bar in operable partition acoustic performance with an unprecedented industry leading 56 STC along with automatic operation courtesy of the SureSet™ top and bottom seal mechanism.

Acousti-Seal® 931

An application workhorse that is more than up to the challenge of most space requirements, Acousti-Seal® 931 provides a wide variety of STC options for your space division needs utilizing a slim 3” platform. Acousti-Seal® 931 is the perfect option for those unique applications where custom finishes or window cutouts are desired.

Acousti-Seal® 911 - Fire Rated

Featuring many of the same great benefits as Acousti-Seal 931, the Acousti-Seal® 911 also features a 1-hour fire rating which provides the extra safety precautions that some spaces or buildings require when utilizing operable partitions. This 1-hour fire rating is tested at Underwriters Laboratories (UL®) per UL® 10B or NFPA 252.
