About NEUWALL — Manufacturer of Operable Partition Walls and Movable Glass Walls Since 2009

What does NEUWALL manufacture?

NEUWALL manufactures two product families. Operable partition walls are solid acoustic panels that park against a track end when the opening is closed, so a ballroom, conference hall or office floor can be reconfigured without rebuilding. Movable glass walls use frameless tempered glass panels that divide spaces while keeping sightlines and daylight.

Every operable system is top-hung: panels ride on a ceiling-mounted track and the floor is left clear, which is why operable partitions are installed after floor finishes. Standard systems are operated manually; NW840-W is also available with semi-automatic and fully automatic drives for large openings moved several times a day.

How does NEUWALL build an acoustic wall?

Acoustic performance comes from the panel construction rather than from a surface finish. A NEUWALL panel combines a welded internal frame, a dense mineral wool core, rigid facings on both sides and a perimeter seal that closes the gap between adjacent panels when the wall is extended.

On the NW840-W steel system the construction is a 2 mm welded heavy-duty galvanized steel frame with an 80 kg/m³ acoustic rock wool core, 12 mm facings, and a standard 1.2 mm galvanized steel underside. The vertical joint uses a single-piece male and female interlocking profile — one continuous section rather than two abutting profiles — which increases the interlocking depth between panels and therefore reduces sound leakage through the joint. Panels are available with a trimless edge or a trimmed edge, in MDF, steel, fabric, wood veneer or bare faces for field-applied finishing.

Seals are deployed by a waist-height jack mechanism operated from a control handle, so the wall can be opened and closed without reaching overhead. Top and bottom edges use four-finger sweep seals, which give roughly 40% more seal contact points than previous generations and bear directly on the floor and ceiling to close the perimeter gap. Seals must be retracted before any panel is moved; operating a wall with its seals extended causes permanent damage.

How soundproof are NEUWALL operable walls?

NEUWALL panels are rated Rw per ISO 717-1, the laboratory airborne-sound standard. The range is Rw 40 dB at the entry level to Rw 55 dB at the top of the range.

For projects specified under US practice, the NW840-W system additionally carries a verified STC 55 dB rating tested to ASTM E90 (report XMIN180500970CCM).

How durable is the track and trolley system?

The aluminium track and trolley assemblies passed a 40,000-cycle durability test conducted by SGS on 2018-06-06, following BS 4875-7:2006 L3 and ISO 7170:2005 clause 7.2.3. All cycles passed. The test covers 1,000 mm of travel per cycle at 6–15 cycles per minute, with lubrication every 10,000 cycles.

Track capacity varies by system: the NW80 aluminium track is rated to approximately 450–480 kg/m with a maximum panel weight of 380 kg over spans to 5 m; the NW100 track is rated to approximately 650 kg/m with up to 650 kg per panel over spans to 6 m. Panels must be kept centred within 762 mm of the track centreline, and the ceiling void must be checked for obstructions and flanking sound paths.

Where does NEUWALL manufacture and ship?

Panels are manufactured at NEUWALL's own facility in Guangzhou, China and shipped under HTS classification 9403.60.8080. Typical terms are CIF Nansha. Each project is supplied against its own approved submittal, shop drawings and structural calculations — standard sections are shown on the drawings only as reference and do not replace project-specific design.
