Designed for a Comprehensive Range of Sound Control

Uninterrupted visibility, with insulation from unwanted noise. With sound-enhanced engineering and various options for sound-controlled design, create the acoustic environment that best suits your space.

Specifying Your Sound Preferences

Matched to Your Specific Needs

In order to choose the best product, it is important to first determine what the optimum level of acoustical buffering is required for your space.

For simplification, we have segmented NanaWall sound-rated opening glass wall solutions into three categories

Lower Range Up to STC 35

Mid Range STC 36 - 42

High Range STC 43 - 45

Minimal Sound Transmission

Opening glass walls with acoustically separated framing, specialized gaskets, and sound enhanced glass make excellent, flexible acoustical barriers within interior space.

Single-Source Engineering

Each glass wall model is comprised of single-source components engineered for that particular system. This produces a higher quality product of lasting performance.

Sound-Enhanced Interlayer

NanaWall opening glass walls can be specified with various acoustic glass options from monolithic to sound enhanced laminated to double IGU to meet noise-reduction requirements.

Top-Hung Systems with Unlimited Opening Widths

Top-hung Opening glass walls are available in single track sliding, folding, and frameless options. These systems have capabilities of unlimited opening widths and ride in a single head track with options of floor tracks or no floor track. Most top-hung systems offer the ability to park the panel remotely out of the plain of the opening.

Floor Supported Systems that Offer Durability and Smoother Operation

Floor supported systems are available in both folding and minimal framed sliding options with different choices of floor tracks. The system's main weight is carried by the floor track. These systems are ideal for applications where the load-bearing capability of the header is a concern.

While some sound control products require tools to crank and seal panels when closed, NanaWall acoustic glass walls offer the user ease of operation. Our products are engineered with roller systems and acoustic seals that do not require additional efforts when closing. It is important to note that when the STC requirements of the system go up, so does the weight of the glass used within the panel. Do not overload your specification requirements when the environment or surrounding conditions may not require the highest acoustical values.

With a wide breadth of sound-rated opening glass walls, NanaWall offers aesthetic product options to interior architects and designers.

With a glass-to-frame ration of over 80% (or more with our Frameless product), glass choice adds to the aesthetics of the interior space. Glass options also include low iron, whiteboard, and a cool white or arctic snow colored interlayer for different levels of translucency and privacy.

Acoustic glass partitions provide versatility and flexibility within interior space to easily and aesthetically create private rooms.

Cost is determined by what level of acoustical privacy and which opening glass wall system is best suited for the location. With a range of products that achieve up to STC 45, it is important to only specify the product and acoustically enhanced glass type that you truly need for any given space. Do not overload the requirements when not necessary.

To achieve the desired acoustical control of any room, it is important that the sound-rated opening glass wall is properly installed and is matched and surrounded with comparable ceiling, walls, and floor.
