Today’s drive for economic 

efficiency demands flexibility 

and ‘multi-tasking’. 

Movable walls provide the key to 

competent management of your 

space and Alco Beldan has the 

expertise to provide the 

opportunity for you to make the 

very best use of the space 

available. 

NW 100 WALL PANELS ACHIEVE AN 

ACOUSTIC RATING OF RW 59dB 

with a panel thickness of only 100mm up to Rw 57dB 


Total Flexibility 

Alco Beldan has emerged as the country’s leading supplier of 

acoustic movable walls. After many years working in this highly 

specialised trade, we have built up an admirable reputation for quality 

with both Architects and their clients. 

THERE ARE GOOD REASONS WHY: 

QUALITY BY DESIGN. 

Each component is designed to do its job precisely, with no expense 

spared on research and development. The product has been 

designed to give the best performance through years of effective 

service, day in, day out. 

QUALITY IN MANUFACTURE. 

Our European factory has achieved ISO 9001 accreditation. The 

panels are built on a dedicated production line, utilising modern 

machinery and are delivered, fully assembled, direct from either our 

factory in the Midlands or from one of our other facilities in Europe. 

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 

and clients, offering our advice and expertise where the opportunity 

presents itself, we seek to optimise the space available, and create a 

visually impressive environment within the budget constraints, whilst 

maintaining the overall programme schedules.

From Church Halls to Sports Halls and Community Centres to 

Convention Centres, our wall does them all. Thousands of users 

have benefited from carefully thought out solutions using the same 

basic product. As the name suggests, the NW100 panels are always 

100mm thick, except special Rw 59dB and fire resistant versions. 

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 

schools etc.

Swaminarayan Hindu Temple 

Architect: Triad Architects, London 

Internationally recognised as one of the most ornate buildings of the 

world, the Swaminarayan Hindu Temple, in North London has used 

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 

complete floor area of 2,300 m 2 

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.

The Celtic Manor Resort 

Architect: Goff Associates 

There cannot be many in the independent hotel sector that haven’t 

heard of the rebuilding of the Celtic Manor Hotel. Travellers along 

the M4 corridor at this gateway into Wales cannot miss this magnificent 

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 

walls so when closed, they fully integrate with the high quality décor, 

and when not in use the movable wall panels are concealed in 

recesses around the Hall. 

To complement the colours used in the traditional Celtic design on the 

ceiling, the panels were faced with burr poplar veneer with contrasting 

inlays and American cherry mouldings for skirting and dado rails, 

complete with bronze colour coded edge profiles.

Shaw Park Plaza 

London 

The project is interesting because it is on the site of the George 

Bernard Shaw Theatre, part of which has been incorporated into 

the scheme. The movable wall in the main function area is 4300mm 

high and has a sound reduction rating of Rw 53dB. The panel finish 

on our walls complement and match the structural walls around the 

rest of the room. Movable walls are also installed in the reception 

breakout area leading into the main function room and incorporate 2 

sets of double pass doors. Additionally, operable walls have been 

installed in the syndicate rooms with a sound reduction of Rw 50dB. 

The Nicholas Grimshaw designed new stand at Lords Cricket 

Ground has a number of private boxes divided by Alco Beldan 

100 Series Movable Walls. 

Acoustically these walls had to be manufactured to the highest 

standard (58dB) to maintain privacy. 

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. 

Lords 

Alco Beldan have also installed movable walls in the offices of the 

English Cricket Board, which is also within Lords grounds.

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 

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 

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 

required 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 recessed 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 NW 100 movable wall 

system offers the best levels of acoustic 

performance up to Rw 57dB from 

panels just 100mm thick. The 

superlative performance of the top 

version at Rw 59dB requires a panel 

thickness of 120mm. NW 100 movable 

wall panels were tested by an independent 

laboratory in full accordance with the latest 

(2002) version of ISO/EN 20 140-3. The Rw 

57dB walls were also tested with acoustic 

boards fitted to one side and to both sides 

(see pages 26 & 27). Test reports and 

certificates available on 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

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 high- 

pressure 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. 

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.

Acoustic 

Ratings 

Noise is defined as unwanted sound and it is usually just a nuisance but at 

times it can be a real headache. It invades privacy and causes disruption, 

when all everyone wants is a little peace and quiet. 

Movable walls are designed to divide areas of a room and control the level of the 

noise or sound travelling from one area to another thereby reducing the nuisance, 

creating an agreeable environment. 

Alco Beldan NW100 

movable wall panels are 

designed to provide 

effective sound control by 

the following means: 

breaking the vibration path 

absorbing the sound energy 

blocking the noise path 

When considering Noise 

Control it is important to 

appreciate the difference between 

sound absorption and sound 

insulation. 

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. 

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. 

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.

Note 1. Special version 120mm thick 

The 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 

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. 

Naturally each manufacturer will 

try to show that their product 

provides the best acoustic 

performance, but the only way in 

which each product can be 

compared equally is by laboratory 

test results. Adoption of the new 

Standard EN ISO 20 140-3 means 

that a new method of testing has 

recently been introduced. If a 

specifier requires that a product 

must be tested in accordance 

with EN ISO 20 140-3, then the 

only valid test certificates are 

those showing the results of tests 

carried out in full accordance with 

that Standard by an independent 

test laboratory. The results are 

expressed as Rw values only.

The 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. 

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 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 

26 and 27. 

Acoustic Performance 23


24 

To 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.

Fire and Smoke Resistance 

Designed to Make Life Safer 

As market leaders, Alco Beldan NW100 movable walls are now 

available in five levels of Fire Performance. Options include Fire 

Resistance of 30 and 60 minutes, Smoke Protection, Class '1' Spread 

of Flame rating and Class 'O' fire propagation. 

FIRE RESISTING WALLS 

Our type NW115 F is a 

movable partition wall which 

has been tested in accordance 

with DIN 4102-T2 and achieved 

60 minutes with class A2 (nonflammable) 

cladding boards. This 

was also tested with B2 (normal) 

cladding boards and achieved 30 

minutes. The same construction 

was also tested for sound 

reduction and achieved ratings up 

to Rw 54dB in accordance with 

EN 20140-3 (1995). This type 

NW115F is also smoke resistant 

to DIN 18095-2 

SMOKE RESISTING WALLS 

Our type NW100 RS is a 

movable partition wall which 

has additional modifications to 

make it smoke protected in 

accordance with DIN 18095-2 

CLASS '1' SURFACE SPREAD 

OF FLAME 

If there is no requirement for fire 

resistance specified and only 

reduction of flame spread is 

needed, we offer our type 

NW100S. This is our standard 

movable wall, which is 

constructed almost completely 

using non-flammable materials, 

but with B1 (difficult to ignite) 

cladding boards or sheet steel 

covering. Although this 

construction reduces flame 

spread, it is not the same as the 

'F' construction and therefore has 

no fire resistance rating. It has no 

General Building Control 

Certificate. 

CLASS 'O' FIRE PROPAGATION 

In order to comply with the more 

demanding Class 'O' 

requirements, our NW100S 

movable wall can be supplied with 

A2 (non-flammable, no 

contribution to combustion) 

cladding boards. 

Alco 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 


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’. 

Fire Resistance 

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. 

The new NW 115 F system has 

been carefully developed from the 

standard NW 100 S and many 

features are similar as detailed in 

specification below: 

Panel choice: Similar to NW 100 but 

No glazing cut-outs 

No lip seal joints 

No door panels (not tested) 

Panel thickness: 115mm 

Internal Frame: Peripheral welded steel section as NW 100 

Panel cladding: 16mm boards rated A2 or B2 depending upon fire rating required. 

Finishes: Laminate, veneer or paint (max thickness 0.5mm) 

Inter-panel joints: Aluminium profiles with magnetic inserts as NW 100 

Vertical edge profiles: Concealed type CP only 

Acoustic seals: Special seals with intumescent strips at top and bottom 

Seal operation: As NW 100 

Track: G M Steel with special protective track cladding 

Sound insulation: Rw 49dB up to Rw 54dB (laboratory tested in accordance with ISO/EN 20140-1995). 

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.

You now have the ideal 

opportunity to incorporate 

optimum smoke protection right 

from the start when using 

movable walls with the Alco 

Beldan NW100RS, available now. 

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 

Smoke Resistance 

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. 

Until now, there has been no one 

in the movable wall market to 

provide a solution which lowers 

the penetration of dangerous

laboratory. 

smoke bearing gases into a room. 

Movable walls which control 

smoke give the occupants 

valuable additional time, which 

can save lives in the event of a fire. 

Our technicians have modified the 

standard NW100 panels and by 

using a new sealing technique, 

protected by German Patent No: 

DBGM 299 03 466.6, have 

achieved the improved smoke 

retention characteristics. 

When in the closed position, the 

Alco Beldan NW100 RS movable 

wall system complies with the 

strict requirements of DIN 18 

095/2, but offers no fire protection 

rating. 

Electric Operation 

Designed to Make Life Easier 


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.

THE BENEFITS OF A NW100 PANEL 

Externally, most movable wall panels look the same, but it's not 

simply the outside which makes a good movable wall, its what's 

inside the panel which makes the difference. 

A movable wall is a significant investment and unless you already have a 

movable wall installed, how can you tell how good it is? Are you buying 

a juicy peach or a bitter lemon; you can only tell by opening it. 

So what makes our movable walls different?

The Visioplan range of folding walls provide economic and versatile 

solutions to your space division needs, where the ease of 

operation of a concertina partition combines with the appearance of a 

flat movable wall. An extensive range including fire resisting versions 

and options for half and fully glazed panels

• 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.

Introduction 37

Visioplan

Carden Park 

Carden Park has been a significant Cheshire Estate since the 17th 

century and its parkland makes an ideal setting for a luxurious hotel and 

golf resort. The par 72, championship course, designed by Jack 

Nicklaus, is served by a superb new clubhouse, catering for the variety 

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.

Glazed folding screens for internal use. 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.

ALUMINIUM SYSTEMS 

The SUNPLAN aluminium systems are manufactured to exacting 

standards. The profiles have flush surfaces and can be specified with 

thermal separation. The glazed panels are carried on tracks integrated into 

the outer frame which may be partly or fully recessed into the floor. 

APPLICATIONS 

SL 35 – for patios, room dividers and unheated conservatories. 

SL 45 – for applications above and shop fronts in malls. 

SL 50 – for heated conservatories and swimming pools. 

DESCRIPTION: 

Glazed sliding folding panels consisting of flush fitting aluminium profiles, 

running in either head or floor tracks with lever operated shoot bolts to 

secure alternate panels. 

OUTER FRAME: 

Constructed using powder coated aluminium profile sections incorporating 

head and sill roller guides. The sill sections may be partly or fully recessed 

into the threshold. 

PANEL FRAME: 

Powder coated aluminium profile sections bonded together to give flush 

finished surfaces at joints with glazed units ‘tuned’ into the frame using 

wedges and clip-in glazing profiles on the inside to allow glass 

replacement. 

ROLLER SYSTEM: 

(Head) - Height adjustable, four wheeled carriages designed to carry 

200kg, with articulated body to evenly distribute loading, and directional 

guide rollers. Rollers fitted with sealed for life bearings and coated with 

toughened polyamide for quiet running. 

(Floor) - Two wheeled carriages designed to carry 200kg, with flange

handle operating aluminium locking rods to extend polyamide cones 

28mm at head and sill. 

LAMINATED WOOD SYSTEMS 

The SUNPLAN wooden systems are ideal for internal use where a more 

traditional effect is required. Also manufactured to the highest quality, the 

selected timbers are processed as multi-laminar bonded strips with 

additional strengthening by concealed metal inserts. The ‘furniture quality’ 

finish of the wood is preserved by using open pore coatings to retain the 

natural character of the wood.

fill the gap between hinged folding walls and vinyl sliding-folding 

partitions with a variety of options designed to provide an alternative 

solution. 

The Alternative Solution 

An easily operated folding wall with robust internal lever mechanism to 

lock the panels absolutely flat when closed across a room, giving the 

appearance of a flat smooth panelled wall without visible hinges. Top 

hung with no floor guide. The leaves operate smoothly and quietly 

along an aluminium overhead track. The deep section aluminium 

leading edge profile incorporates a magnetic insert that combines with 

a special action latch for positive closure. Once the door handle 

releases the lever mechanism, the hinge system allows the bunched 

leaves to fold back unobtrusively to the side of the opening. Adjustable 

jamb posts mean the sides of the wall are neatly fixed without packing 

or architraves. Available in a choice of finishes including veneers and 

melamine with a choice of white or dark brown for the door handles.

Simple and Effective 

Foldacord vinyl sliding / folding partitions provide simple and 

effective everyday room dividers where value for money is 

important. They are ideal for applications where the available space 

has to be changed frequently without fuss. 

These top hung partitions are custom made to almost any size from a 

servery hatch to a dividing partition for a large sports hall, but are 

equally useful in schools, religious buildings, and of course, hotels and 

restaurants. The neat regular folds of the vinyl covers are equalised by 

a clever internal pantograph mechanism retaining a galvanised steel rod 

framework which also facilitates the easy extension of the partition 

across the opening. The mechanism is governed by a limiting tape, 

which prevents over-stretching. When at the side of the opening, 

bunched wings are retained by matching tie back straps. Curved tracks 

and switching joints allow bunched wings to be stored parallel against 

side walls instead of projecting into the opening. The washable, flame 

retardant vinyl covers have seams reinforced with fabric webbing, and 

are available in a wide range of colours and textures. With two frame 

sizes available, your choice of acoustic insulation ratings extends up to 

Rw 37dB.
