High Performance and Durable GlassWall

Ultra™ Acoustic GlassWall™ is designed and manufactured for all movable partition situations where sound control, long term durability and open views with light transmission are needed.  Like all Hufcor products, Ultra™ Acoustic GlassWall™ is built to exacting standards, proven through extensive testing and will stand the test of time in the most challenging environments.  This unique combination makes it perfect for use in schools, hospitals, office buildings, commercial centers – anywhere that groups gather to communicate while being seen — but not heard.

Innovation Combined with Creativity

Found in buildings across markets around the world, Hufcor Ultra™ Acoustic GlassWall™ can be configured in many ways to meet your space requirements.  Choose from single or paired panels.  Perhaps add an in-line pass door with locking hardware.  We also offer a wide range of metal and glass surfaces and treatments to compliment any decor.

Select from a wide range of design options such as single or paired panels, work surface insets, inset pass doors including those that meet ADA requirements as well as custom glass options and trim finishes.

Sound Management and Acoustic Separation

Hufcor is the industry leader in movable partition sound management, and Ultra™ Acoustic GlassWall™ moveable partitions come in range of construction and glass styles that minimize sound transition.  At Hufcor we test our products in our sound laboratory in accordance with ASTM E90 and ISO 10140-2 for sound blocking and ASTM 423 for sound absorption to ensure they meet or exceed our published acoustical ratings. The laboratory is certified by the National Voluntary Laboratory Accreditation Program (NVLAP Testing Lab Code 100239-0), and we undergo regular inspection to make certain we adhere to their strict regulations.

New or Existing Construction

Ultra™ Acoustic GlassWall™ can be installed in either existing facilities or new construction. And when supported by Hufcor’s Unispan® support system, the facility engineering and preparation for supporting movable walls is greatly simplified with reduced costs for engineering and materials.

Brighten and Improve the Quality of Your Space

Designing glass panels into your facility allows natural sunlight into your space, which could qualify for LEED points for Indoor Environmental Quality (IEQ) Credit 8.2: Daylight and Views.

Clear Floor – No Floor Tracks

Hufcor movable partitions are supported on tracks from above — no floor tracks to get in the way, no tripping hazards, no interference or limitations on clear floor space and no crevices to collect debris.  When an acoustic bottom seal is needed, the seals are incorporated and activated from within the operable panels.

STC Rating up to 46













Focused on Customerization

When it comes to space, there is no such thing as one-size-fits-all. At Hufcor our talented team of engineers will provide their expertise and work collaboratively to deliver modifications or custom solutions to meet your needs. No challenge is too big or too small. We’re always eager and willing to understand the specific requirements of your project to deliver exactly what’s needed.

Partition Studio™

Architecture starts with flexibility and base of design which is why Hufcor created Partition Studio™.  This proprietary software program allows for easy input of operable partition dimensions and design criteria and produces quick turn around CAD drawings including partition storage options, track systems, support punching templates and pricing to keep projects on budget and on time.

Partition & Track Types

Single (OMNI) Panels

The best manually operated partition choice when room flexibility is important. The track system enables curved runs and panels which can be set at angles or in alternative, creative locations. Self storing options including pocket doors solutions are available.

Paired Panels

For wall-to-wall division, these manually-operated panels are hinged in pairs. Paired panels are popular for fast setup in classrooms, meeting rooms and training centers.

Track Types

There several available track and carrier options for the Acoustic Glass Wall line ranging from aluminum track and carrier designs supporting wall panels up to 500lbs (226kg) to all steel tracks that can support panels up to 3,000lbs (1,360kg).

ADA Approved Glass Door

Hufcor pass doors comply with ADA requirements and are of the same construction and finish as the panels.  No threshold or foot bolt stabilizers are required.  Pass door options include:

  • Exit signs
  • Automatic door closer
  • Panic Hardware
  • Locks

Taller Height Options

Ultra™ Acoustic GlassWall™ can be installed in openings up to 12’2″ (3.7m) tall without the need for glass panel dividers or mullions.  In-line pass doors in a tall height installation can also employ an optional window above the door.

Partial Height and Work Surface Insets

  • Untrimmed dry erase steel markerboards, inset or full-height
  • Inset porcelain enamel steel dry marker or chalk board. Includes a full-width pen or chalk rail. The markerboards resist damage, abrasion, scratching and color fading.
  • Eraser pocket — this handy inset pocket holds a standard markerboard eraser, pens or other work surface accessories
  • Tackboards are inset and are covered with Hufcor’s standard vinyl

Sound Absorptive Faces

Ultra™ Acoustic GlassWall™ is best in class at minimizing sound transmission (STC), but if minimizing sound reflection and maximizing sound absorption (NRC) is also necessary, Hufcor can add sound absorption panel surfaces to further manage sound.

Hinged Closure Panel

The standard final closure when using glass wall is a hinged closure panel. These swing doors are located at either side of the glass wall partition and allow for entrance and egress within the divided rooms.

Unispan® Structural Support System

Unispan® is pre-engineered independent support system compatible with Hufcor operable, acoustic glass or accordion partitions for quick, easy room division. Unispan® makes flexible space possible by providing added support to spaces that lack the required overhead structural support to carry the weight of operable partitions. Read More

Glass Finishes

While you can select from a limitless range of glass finishes and treatments, we embrace customization.
