QUALITY OF OPERATION. Drawing on the wealth of design experience gained by our technical staff, our schemes are both innovative and cost effective. We also offer on-site staff training after installation, because we understand that ordinary people use the panels every day, long after the ‘experts’ have left the scene. Most projects begin with the spark of an idea, whether originated by the need for more usable space in an existing building or the desire to provide for greater range of activities in a new development. Each project then becomes a challenge which calls for comprehensive analysis in order to achieve its own individual solution. Alco Beldan’s nation-wide team of technical advisors understand the demands of integrating a movable wall system. Early and careful consultation can solve many of the problems encountered whilst taking a project from concept to completion. By working alongside Architects

have benefited from carefully thought out solutions using the same basic product. As the name suggests, the NW100 panels are always 100mm thick, no matter what the application or acoustic rating.
By using advanced design technology and selecting the best materials available means we don’t need different models to achieve higher performance. Even the heaviest panels can be moved easily through track junctions allowing full mobility of the panels and flexibility of wall layouts. The Alco Beldan NW100 Movable Wall is a true workhorse, although finished differently, the same panel unit can be found performing its sound reducing function every day in Offices, Hospitals, Schools and Colleges, Community Centres, and of course, Hotels. Whatever the application, the basic requirements are the same; for a well-engineered, totally reliable movable wall system which will perform well over its whole lifetime. The Alco Beldan NW100 Movable wall does just that. • Its not luck nor by coincidence that probably the most well known hotel chain has installed Alco Beldan NW 100 movable walls in over 50 of their hotels. They have demonstrated their confidence in our movable walls, how about you? • Ask yourself how can Alco Beldan reliably deliver and install approximately 100 movable wall panels each working week? Repeat business from hundreds of satisfied customers makes up 75% of our order book. • Acknowledged as world leaders in movable wall technology, our German designed panels are now being developed and built here in the UK. Why don’t you take advantage of the best of both worlds, the best quality at a competitive price? • Alco Beldan are recognised in the Interiors industry for Gold Award winning installations, and we have the confidence gained only from years of experience in handling all types of project from the exotic, with hung silk screen panels to robust and rugged panels installed in

Alco Beldan NW 100 movable walls to acoustically divide the Prayer Hall. The Prayer Hall is the central part of this complex, but because the 2
complete floor area of 2,300 m is used only a few times each year, the Hall needed to be divided into smaller, more manageable and efficient areas for everyday use. Alco Beldan were asked to design a system that would divide the Hall into three separate rooms, yet still be manually moved into place by the resident staff. The impressive proportions of the 51 x 45 metres of Hall floor area is balanced by the 7.20 metres height and this meant there were two important aspects to consider; the weight of the panels and ease of their operation. Each of the panels is carried on two specially developed rollers running in heavy duty steel tracks fabricated to form semi-automatic stacking bays at the end of each of the three movable walls used to divide the Hall. The staff only have to roll the panels into the 45° track junction and the panel turns easily into the stacking position. Although the panels are just 100mm thick, their acoustic rating is R’w 51dB, and this is enhanced by the addition of a special herringbone pattern acoustic wallcovering applied by the main contractor. The client is delighted with the performance of the panels and in particular, the ease with which these panels, some of the tallest in the country, are moved into place.

hotel which sits in an imposing position high on a hill overlooking the motorway. As expected of one of ‘The Leading Hotels of the World’ the interior facilities are no less impressive with a carved Welsh Dragon dominating the foyer, leading to 400 rooms and superb restaurants all serving an international standard Convention Hall, the Caernarfon Suite. Alco Beldan NW 100 movable walls have been installed in the convention hall and the syndicate rooms but the most difficult challenge facing the technical staff was how to support the 6.30 metre high panels in the Caernarfon Suite. Above the ceiling is a 5.00 metre deep void to the substantial roof structure, which also supports the car park. In order for the heavy panels to operate in all conditions we had to take account of 100mm dead-load deflection in the roof structure which could deflect a further 50mm under live load from the car park. The key to this successful solution was our standard rapid action scissor link mechanism, which provides more than 50mm of spring assisted travel to our unique, double depth top and bottom seal carriers, specially developed for this job. Each panel is suspended on two rollers running in heavy duty track and both roller hangers are fitted with self-locking height adjustment devices which prevent the panels losing level alignment. The track layout provides options to divide the Suite into six, with doubled up tracks at the centre so two walls may be set up in a duplex configuration for very high acoustic separation between the two areas. The resulting acoustic performance from a duplex set of Rw 58dB rated panels was assessed as Rw 65dB or better. The panels are finished to match the panelled effect of the perimeter

The success of the installation has created flexibility for Lords to also lease out the enlarged boxes as meeting rooms to companies. This again creates a multiuse stand that does not stand empty when there is no cricket.

GENERAL DESCRIPTION The Alco Beldan NW 100 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
16
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
IMPACT RESISTANCE
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

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

SOUND REDUCTION Steel frame
The Alco Beldan NW 100 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.

hen considering Noise Control it is important to appreciate the difference between sound absorption and sound insulation.
he sound insulation level of a movable wall is graded by its Sound Reduction Index (SRI). This is usually derived from the results of laboratory tests and is expressed in terms of 'Rw dB', being a single figure based on a weighting system defined in BS/ISO/EN 20.140

T
Sound Absorption refers to the attenuation of the reverberant noise within the same room and therefore it mostly falls outside the scope of a movable wall system. However when a sound wave hits a movable wall some of its energy will be reflected and some absorbed.
Since the results of laboratory tests are obtained in perfect conditions where there is no flanking sound leakage, they cannot be replicated on site where flanking leakage is always present at various levels. The normal loss between laboratory and site performance is 3 to 8dB, depending upon how much care has been taken to eliminate sound transmission paths. No movable wall nor partitioning contractor can guarantee any particular 'on site' performance because flanking transmission is beyond their control.

h pat
Sound Insulation, (also known as sound reduction) is the prevention of noise being transmitted from one area to another, by erecting a partition wall, for example. The ability of a partition wall to resist the passage of sound energy through it is largely determined by its mass, but structural isolation of the two surfaces and sound absorbency of the cavities in the construction are other factors which enhance the overall performance.
Naturally each manufacturer will try to show their product provides the best performance acoustically, but the only way each product can be compared equally is by a laboratory test result. Recently the testing method has been altered to take into account a wider range of frequencies and hence test results obtained prior to 1995 are invalid. The latest test procedures provide test results at frequencies from 0 through to 5,000hz and the average figure is expressed in terms of Rw. The relevant standard is now BS EN ISO 140-3, 1995 in which results are expressed as Rw values only.
An Alco Beldan NW100 movable wall combines these 3 factors by: Using dense cladding boards to add to the mass. Careful detailing of the internal components to isolate the boards from the inner steel frame and slabs of mineral wool infill within the cavity to increase the sound absorbency. Attention to detail is all important and that is why even the cavities of the seal carriers at top and bottom of the panel are filled with mineral wool.

he performance scale is logarithmic which means it is quite easy to achieve acoustic improvement at the lower end of the scale but very difficult to achieve significant improvement at the higher end. Its similar to squeezing water from a saturated sponge and partly explains why it is more expensive to raise the acoustic performance by 2dB from 52dB up to 54dB than it is to raise it from 41dB to 43dB. An increase in insulation of 10dB will correspond to a halving of the perceived loudness of the noise.
T
The perception of noise is subjective, some people have more acute hearing than others do, and therefore we must understand exactly what level of insulation the client is expecting from the movable wall. In most cases the client's expectation of noise reduction levels cannot be achieved using panels rated lower than Rw 48dB, when flanking transmission losses of 8dB are taken into consideration.
Acoustic Performance

Acoustic insulation is expensive and it is tempting to try to make savings, but this will be false economy if the resulting noise level is still a nuisance. Don't take risks. We can advise you and provide practical 'on site' results based on our experience. ACOUSTIC CHARACTERISTICS To achieve the optimum audible condition in a room, it is necessary to consider reverberation times. In general, a concert hall needs acoustically 'live' conditions, whereas a seminar room needs reduced levels of reverberation for intelligible speech. Alco Beldan NW100 movable wall panels can be faced with special acoustic slotted boards which can improve the acoustic characteristics of a room by increasing the sound absorption levels. Refer to section on pages 24, 25.

o determine the correct level of sound reduction for any particular circumstance is a complicated process, and for an accurate appraisal, it is better to obtain the advice of an Acoustic Consultant. However, it is possible to obtain a reasonably accurate prediction of expected performance by comparing the results obtained by other methods of dividing rooms, and by using information from various sources, the table shown below may help to identify the required level of noise reduction.

lco Beldan are aware of new European initiatives to harmonise the various national Fire and Smoke Regulations of member states within the European Union. To prepare for the introduction of new EN standards, our German manufacturing partner, Franz Nusing GmbH & Co., has developed a new range of Fire and Smoke resisting movable walls.
A
The new standard is DIN EN1364-1. Fire protection in buildings is a matter of Public Safety and must be considered extremely carefully and seriously. The Specifier must first establish the level of Fire Protection required by the Authorities in respect of a movable wall system which is classed to as a ‘non-load bearing wall’.
It must be remembered that movable walls are not self-closing and therefore cannot be classified with a F30, F60 or F90 rating. Because of their mobility, the fire resistance rating of a movable wall only relates to its performance when in a closed position with the seals fully extended. With something as important as preservation of life, it is essential that products are appraised in accordance with the test procedures and certificates of verification must be provided. When tested in accordance with DIN 4102-T2, a movable wall which successfully passes the test will be issued with a General Building Control Certificate. The Alco Beldan NE115 F has recently been tested in accordance
with DIN EN 1364-1 classification and General Building Control Test Certificates have been issued for 30 minutes and 60 minutes fire resistance. The sample tested included several inter-panel joints, grooves, fixings, wall posts etc. This is therefore a fully movable partition wall which when fully closed and locked in position, achieved the same fire resistance as a fixed wall. The NW 115 F movable wall system meets the requirements of the Building Regulations and currently represents the best movable partition wall for the protection of escape and rescue routes.

It is most important to remember when considering Fire Resisting movable walls, that only those products which have successfully passed the Fire Test are awarded a Building Control Certificate. There is no reason specifiers should be put off insisting on inspecting a copy of the test data by vague covering statements such as testing in accordance with ‘DIN 4102 F30 quality’ or ‘F30 A/B flammability’ since such statements mean nothing.

In the event of a fire, creeping smoke is the greatest danger.
Most people perceive the development of heat in a fire as being the most dangerous aspect; however fire experts know the accelerated spread of smoke has a higher potential for danger. In such situations, escape for the occupants of the building
along emergency escape routes is made difficult and the dense smoke hampers the job of fighting the fire by the Fire Service.
For these reasons, fire protection experts recommend that normal smoke and heat extraction equipment be supplemented by the provision of smoke protection doors and building elements which prevent the spread of smoke.

flat movable wall. An extensive range including fire resisting versions and options for half and fully glazed panels The main features of the VISIOPLAN range are: • Pass door available, in most cases, at no extra cost. • Choice of Floor Supported or Top Hung systems. • Convenient handle operated securing bolts. • Versatile range of decorative finishes. • Glazed options in timber or aluminium frames. • Fire resisting version available.
STANDARD VISIOPLAN Visioplan systems are normally designed to run along a shallow, surface mounted, aluminium floor track, but where structural support is available, the top hung version without a floor track may be used. The low profile floor track overcomes trip hazard and dirt accumulation problems. Floor tracks must be fixed to a horizontally level surface. Continuously hinged from a wall jamb, single wing panels fold to one side of the opening with a single pass door as the last panel but a double wing system offers a central, double pass door set. Pass doors with 'D' ring handles and cylinder locks are standard. Each alternate panel is located and secured with a self-adjusting bolt using a convenient removable key handle. When bunching, the panels may be folded equally on the track centre-line or eccentrically to one side of track. With the exception of most economical, Type 40, each panel has understated aluminium profiles to protect the vertical edges and complement the range of veneers, laminate, melamine or painted surfaces which are available. Our wide range of acoustic ratings up to Rw 46dB cover all but the most demanding situations.

of corporate functions offered. In order to optimise the flexibility of this two storey building, the Architects wanted to use three, high quality, folding walls to divide the first floor into four rooms which could be enlarged as necessary. The structural support available from above varied, as did the required stacking arrangements and the flexibility of the systems provided ensure that the Architect was able to overcome all the design obstacles. Our Visioplan range of sliding-folding flat panels provided the ideal solution. Being of composite construction, the internal acoustic insulation was altered to match the requirements and the choice of top hung or floor supported roller units, combined with centre-folding or end-folding panels, meant this one product met the different conditions at each of the locations. In the bar area, the folding wall consisted of narrow leaf panels, which are concealed, unobtrusively, in a deep narrow recess blending into the end of the bar counter. In the main lounge however, a large feature fireplace provides the opportunity to store the panels away within the chimney breast and since these panels were top hung, centre-folding and needed no floor track, there was no interruption to the run of carpet through the two rooms. It was equally important that the panels complement the interior decor. The adjacent walls are finished with raised and fielded feature panels and although it is not possible to fix timber mouldings to the surface of the folding panels, a similar effect was achieved by routering a double depth profile into the panel face. This example of lateral thinking perfectly demonstrates how our clients benefit from our wealth of technical expertise. This installation made full use of the options available within the Visioplan range and provided the perfect solution to each of the individual challenges faced by the design team.

Developed using the
successful Visioplan detailing, this refined, glazed version throws
new light on to an old subject, brightening your prospects by introducing glass into the traditional timber framed panels or the clean, elegant aluminium framed panels. Ideal for Day Centres, Schools and Hospitals. TIMBER FRAME A series of custom made, timber framed panels, which are continuously hinged and are easy to operate. Available either top hung or floor rolling where structural support is not adequate to carry the weight of the panels or when bunching off-centre of the track. Sweep seals are fitted at top and bottom of each panel to enhance the acoustic properties. A pass door, fitted with a D-ring handle and latch, is usually included in the run of panels at no extra cost. The door may be located in the centre of the opening when using a double wing system. Finished in high density paint as standard, panels are available in a choice of finishes, extending to veneers, laminates or melamine and may be fully glazed with a mid-rail or half glazed in clear or obscure glass. ALUMINIUM FRAME These panels are assembled from extruded profiles in white lacquered finish providing clean attractive lines. As with the timber-framed system, panels are top hung, requiring a floor guide only when using end-folding configuration. Panels are fitted with integral sweep seals at top and bottom edges, and are interconnected by butt hinges. Each alternate panel is secured at the floor with slide bolts engaging into sockets, or the floor guide when using end-folding stacking. Horizontal or angled cross rails, to co-ordinate with the interior design of the room, can be supplied and are recommended for use within taller screens to meet safety requirements. In addition to the standard white finished profiles and 6mm plain glazing, various alternatives can be offered upon request. Remote stacking is also available using separate panels on two-point suspension.
