GENERAL DESCRIPTION
The Alco Beldan NW100 is a rapid action movable wall system designed for easy, efficient and reliable daily use. Interlocking, individual panels, 100mm thick, carried on rollers running in a top track only, push together with an expanding panel as the last element, to form a complete, secure partition wall. Panels have independently operating pressure seal carriers extending at top and bottom.

PANEL SIZES
Panels are custom made with widths from approx. 650mm up to a maximum of 1260mm. Panel heights from 2.00m up to 10.00m approx.

STANDARD PANEL CONSTRUCTION
Each panel is constructed with a welded tubular steel inner frame, clad both sides with 16mm high density boards, isolated from the internal frame. The cavity is insulated using layers of sound absorbing materials as specified to achieve the acoustic rating. Cladding boards are retained by removable aluminium edge profiles which do not form part of the panel frame.

INTER-PANEL CONNECTION
Sound leakage through the vertical connection between meeting panels is minimised by aluminium interlocking wedgeshaped, tongue-and-grooved, edge profiles with integral magnetic strips. Profiles may be either exposed, to protect the panel edge, or concealed.

PANEL FINISHES
Panels can be finished to suit almost every taste and to match with adjacent décor. Standard panels are finished in durable, high-density melamine-faced particleboard, class E1. Other options include: laminates, selected wood veneers, primer sheet for onsite decoration with wall-coverings, and any combination of these using dado rails and mouldings etc. Sections of pin-board and special absorptive acoustic boards may be incorporated; and for ultimate integration, inlaid veneered feature panels sourced and supplied by the client’s appointed joinery specialist.

OPERABLE ACOUSTIC SEALS
The acoustic seals are housed in deep, twopiece extruded aluminium carrier assemblies that extend independently at the top and bottom of each panel. The black finished carriers have insulated bridging plates to minimise sound transmission. To ensure leak free sealing and secure panel stability, the seal carriers operate under very high (2kN) spring pressure controlled by a manually operated, rapid action scissor link mechanism (with motor drive option). Our scissor link device provides much longer seal travel for out-of-level floors and facilitates easy setting up of the panels by anyone, using a removable handle.

TRACK SYSTEM
Panels are carried on roller hangers running in a white finished metal overhead track, usually concealed into the ceiling. The track must be suspended from a suitable structure adequate to carry the loadings imposed. Track intersections are precision made off-site ensuring smooth transition through junctions into any one of a number of remote panel stacking options

ROLLER SYSTEMS
Special roller units have been developed to match each track to ensure easy movement of the panels through track intersections. Depending upon the configuration, panels are essentially supported using one or two roller units; each on a hanger assembly incorporating our unique height setting device. Tall and heavy panels use a guide roller unit running in special heavy-duty steel track fabricated to facilitate turning of panels into stacking area

HEIGHT ADJUSTMENT
Each roller is fitted with a unique, self-locking height-setting device ensuring the panels remain level whilst allowing the height to be adjusted and re-set at a later date without having to interfere with the ceiling.

SOUND REDUCTION
The Alco Beldan NW100 movable wall system offers the best levels of acoustic performance from panels just 100mm thick. Internal layers of dense insulation materials are combined to increase the acoustic performance, not the overall panel thickness. Independent laboratory test results ‘with flanking transmission’ were reevaluated in accordance with DIN 4109-3 to give equivalent ratings of Rw 52dB up to Rw 58dB. Panels have since been retested in accordance with the latest European standard procedure ISO / EN 20 140-3: (1995). Test report certificates available upon request.

QUALITY ASSURANCE & DURABILITY
Essential requirements of any high quality movable wall system are its build quality and its ability to withstand constant use without adversely affecting performance. Our German factory has attained ISO 9001 accreditation for quality and panels pass the DIN 310.000/3.79 standard test enduring 3,500 operations.

IMPACT RESISTANCE
Tested in accordance with DIN 18032-3

THERMAL TRANSMISSION
Up to 0.6 / m² , depending upon insulating materials within the panel.

Examples of how single or double pass doors can be incorporated into movable walls		PASS DOOR PANEL A pass door panel needs very careful design detailing to minimise sound leakage. The panel construction is as our standard panel but has a bevel gear mechanism to operate full width seals at top and highpressure seals at bottom of both door stiles. The double rebated door leaf is 100mm thick and is set within the panel having stiles at both sides. An automatic adjustable pressure seal extends from the bottom of the door leaf during last fraction of closing movement. Heavy-duty hinges with adjustable sleeves are fitted, as are recessed lever handles.
Our careful detailing makes these pass door panels probably the best in the industry		TELESCOPIC PANEL Most movable wall systems incorporate a telescopic panel to provide a working clearance for operator handling of the panels and achieve a high-pressure, leak free seal at the jamb post. Panel construction is as our standard panel but uses a bevel gear mechanism to actuate an adjustable, internal extending section and the top and bottom seals, sequentially in one winding operation. The extending section is finished to match the panel surface, travels 100 mm carrying top and bottom seal extensions to fully close into the corners. Operation is from one side only.

The extruded aluminium profiles do not form part of the panel frame. Deep, tongued-and-grooved, interlocking profiles with integral magnetic strips ensure the panels hang plumb and joints close tightly together. Aluminium profiles may be colour anodised or spray paint finished if required.

ACOUSTIC BARRIERS The illustration shows the importance of controlling the sound transmission above the movable wall panels. Where required Alco Beldan can install acoustic barriers both above the ceiling and beneath a raised access floor.The acoustic baffle is constructed using layers of high density gypsum boards on a framework infilled with acoustic quilt to match the performance of the movable wall.

Experience has shown that movable walls are not foolproof because the system relies on the operator manually extending the pressure seals at top and bottom of each panel.

Whilst our rapid action mechanism only needs 4 or 5 turns to extend the seals, when pressed for time setting out a long movable wall, an operator may forget to extend the seals on every panel. The result could be complaints about the level of noise through the movable wall.

Electrical operation of the seals not only assures the seals will be extended fully but also achieves this without time consuming handle winding, thereby shortening the setting up process.

With Electric Operation the panels are pushed into place as normal but as soon as the magnetic profiles engage together the seals automatically extend applying the correct pressure to give optimum sound insulation and stability.
