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 58DB
whilst maintaining a panel thickness of 100mm
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.
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.
THERE ARE GOOD REASONS WHY:
Space ManagementTotal Flexibility
Space Management
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.
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, no matter what the application or acoustic rating.

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 m2is 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.

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.

Floor plan of The Caernarfon Suite at The Celtic Manor Resort
This conference centre won theaward for the most effectivefunctional design in theEuropean Hotel design anddevelopment awards 2000.
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.
Alco Beldan have also installed movable walls in the offices of the
English Cricket Board, which is also within Lords grounds.

SOUND REDUCTIONThe Alco Beldan NW 100 movable wallsystem offers the best levels of acousticperformance from panels just 100mmthick. Internal layers of dense insulationmaterials are combined to increase theacoustic performance, not the overall panelthickness. Independent laboratory testresults ‘with flanking transmission’ were re-evaluated in accordance with DIN 4109-3to give equivalent ratings of Rw 52dB up toRw 58dB. Panels have since been re-tested in accordance with the latestEuropean standard procedure ISO / EN 20140-3: (1995). Test report certificatesavailable upon request.

GENERAL DESCRIPTIONThe Alco Beldan NW 100 is a rapid actionmovable wall system designed for easy,efficient and reliable daily use. Interlocking,individual panels, 100mm thick, carried onrollers running in a top track only, pushtogether with an expanding panel as thelast element, to form a complete, securepartition wall. Panels have independentlyoperating pressure seal carriers extendingat top and bottom.
PANEL SIZESPanels are custom made with widths fromapprox. 650mm up to a maximum of1260mm. Panel heights from 2.00m up to10.00m approx.
STANDARD PANEL
CONSTRUCTIONEach panel is constructed with a weldedtubular steel inner frame, clad both sides with16mm high density boards, isolated from theinternal frame. The cavity is insulated usinglayers of sound absorbing materials asspecified to achieve the acoustic rating.Cladding boards are retained by removablealuminium edge profiles which do not formpart of the panel frame.
INTER-PANEL CONNECTIONSound leakage through the verticalconnection between meeting panels isminimised by aluminium interlocking wedge-shaped, tongue-and-grooved, edge profileswith integral magnetic strips. Profiles may beeither exposed, to protect the panel edge, orconcealed.
PANEL FINISHESPanels can be finished to suit almost everytaste 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 on-site decoration with wall-coverings, and anycombination of these using dado rails andmouldings etc. Sections of pin-board andspecial absorptive acoustic boards may beincorporated; and for ultimate integration,inlaid veneered feature panels sourced andsupplied by the client’s appointed joineryspecialist.
OPERABLE ACOUSTIC SEALSThe acoustic seals are housed in deep, two-piece extruded aluminium carrier assembliesthat extend independently at the top andbottom of each panel. The black finishedcarriers have insulated bridging plates tominimise sound transmission. To ensure leakfree sealing and secure panel stability, theseal carriers operate under very high (2kN)spring pressure controlled by a manuallyoperated, rapid action scissor linkmechanism (with motor drive option). Ourscissor link device provides much longer sealtravel for out-of-level floors and facilitateseasy setting up of the panels by anyone,using a removable handle.

Our careful detailing makes these pass doorpanels probably the best inthe industry
Examples of how single ordouble pass doors can beincorporated into movablewalls.
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 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.

* = DIN 52.210 Part 3 ** = DIN 4109 Supplement 3
When considering NoiseControl it is important to
appreciate the difference betweensound absorption and soundinsulation.
Sound Absorption refers to theattenuation of the reverberantnoise within the same room andtherefore it mostly falls outside thescope of a movable wall system.However when a sound wave hitsa movable wall some of its energywill be reflected and someabsorbed.
Sound Insulation, (also known assound reduction) is the preventionof noise being transmitted fromone area to another, by erecting apartition wall, for example. Theability of a partition wall to resistthe passage of sound energythrough it is largely determined byits mass, but structural isolationof the two surfaces and soundabsorbency of the cavities in theconstruction are other factorswhich enhance the overallperformance.
An Alco Beldan NW100 movablewall combines these 3 factors by:Using dense cladding boards toadd to the mass. Careful detailingof the internal components toisolate the boards from the innersteel frame and slabs of mineralwool infill within the cavity toincrease the sound absorbency.Attention to detail is all importantand that is why even the cavities of the seal carriers at top andbottom of the panel are filled withmineral wool.
The sound insulation level of amovable wall is graded by its
Sound Reduction Index (SRI). Thisis usually derived from the resultsof laboratory tests and isexpressed in terms of 'Rw dB',being a single figure based on aweighting system defined inBS/ISO/EN 20.140
Since the results of laboratorytests are obtained in perfectconditions where there is noflanking sound leakage, theycannot be replicated on sitewhere flanking leakage is alwayspresent at various levels. Thenormal loss between laboratoryand site performance is 3 to 8dB,depending upon how much carehas been taken to eliminatesound transmission paths. Nomovable wall nor partitioningcontractor can guarantee anyparticular 'on site' performancebecause flanking transmission isbeyond their control.
Naturally each manufacturer will tryto show their product provides thebest performance acoustically, butthe only way each product can becompared equally is by alaboratory test result. Recently thetesting method has been altered totake into account a wider range offrequencies and hence test resultsobtained prior to 1995 are invalid.The latest test procedures providetest results at frequencies from 0through to 5,000hz and theaverage figure is expressed interms of Rw. The relevantstandard is now BS EN ISO 140-3,1995 in which results areexpressed as Rw values only.
The performance scale islogarithmic which means it is
quite easy to achieve acousticimprovement at the lower end ofthe scale but very difficult toachieve significant improvementat the higher end. Its similar tosqueezing water from a saturatedsponge and partly explains why itis more expensive to raise theacoustic performance by 2dBfrom 52dB up to 54dB than it is toraise it from 41dB to 43dB. Anincrease in insulation of 10dB willcorrespond to a halving of theperceived loudness of the noise.
The perception of noise issubjective, some people havemore acute hearing than othersdo, and therefore we mustunderstand exactly what level ofinsulation the client is expectingfrom the movable wall. In mostcases the client's expectation ofnoise reduction levels cannot beachieved using panels rated lowerthan Rw 48dB, when flankingtransmission losses of 8dB aretaken into consideration.
Acoustic insulation is expensiveand it is tempting to try to makesavings, but this will be falseeconomy if the resulting noiselevel is still a nuisance.
Don't take risks. We can adviseyou and provide practical 'on site'results based on our experience.
ACOUSTICCHARACTERISTICSTo achieve the optimum audiblecondition in a room, it is necessaryto consider reverberation times.In general, a concert hall needsacoustically 'live' conditions,whereas a seminar room needsreduced levels of reverberation forintelligible speech.
Alco Beldan NW100 movable wallpanels can be faced with specialacoustic slotted boards whichcan improve the acousticcharacteristics of a room byincreasing the sound absorptionlevels. Refer to section on pages24, 25.
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.

To determine the correct level of sound reduction for any particular circumstance is a complicatedprocess, 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 comparingthe results obtained by other methods of dividing rooms, and by using information from various sources, thetable shown below may help to identify the required level of noise reduction.

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

Fire Resistance
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.
Alco Beldan are aware of newEuropean initiatives to
harmonise the various nationalFire and Smoke Regulations ofmember states within theEuropean Union. To prepare forthe introduction of new ENstandards, our Germanmanufacturing partner, FranzNusing GmbH & Co., hasdeveloped a new range of Fireand Smoke resisting movablewalls.
The new standard is DINEN1364-1. Fire protection inbuildings is a matter of PublicSafety and must be consideredextremely carefully and seriously.
The Specifier must first establishthe level of Fire Protectionrequired by the Authorities inrespect of a movable wall systemwhich is classed to as a ‘non-loadbearing wall’.
It must be remembered thatmovable walls are not self-closingand therefore cannot be classifiedwith a F30, F60 or F90 rating.Because of their mobility, the fireresistance rating of a movablewall only relates to itsperformance when in a closedposition with the seals fullyextended.
With something as important aspreservation of life, it is essentialthat products are appraised inaccordance with the testprocedures and certificates ofverification must be provided.When tested in accordance withDIN 4102-T2, a movable wallwhich successfully passes thetest will be issued with a GeneralBuilding Control Certificate.
The Alco Beldan NE115 F hasrecently been tested inaccordance
with DIN EN 1364-1 classificationand General Building Control TestCertificates have been issued for30 minutes and 60 minutes fireresistance. The sample testedincluded several inter-panel joints,grooves, fixings, wall posts etc.This is therefore a fully movablepartition wall which when fullyclosed and locked in position,achieved the same fire resistanceas a fixed wall. The NW 115 Fmovable wall system meets therequirements of the BuildingRegulations and currentlyrepresents the best movablepartition wall for the protection ofescape and rescue routes.
The new NW 115 F system hasbeen carefully developed from thestandard NW 100 S and manyfeatures are similar as detailed inspecification below:

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.
Electric OperationDesigned to Make Life Easier
Smoke Resistance
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
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
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.

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
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.
This system can be top hungremoving the need of a floor track

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.

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 inter-
connected 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.
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.

Unrivalled StabilityFoldawall
Atraditional timber, double shell concertina folding wall with internal
link mechanism which when supplied with the floor rolling option
makes this a robust sliding partition with unrivalled stability.
A heavy duty, sound insulating, folding wall which may be either top
hung or floor supported for openings up to 4 metres high as standard.
The high-density chipboard leaves, with flexible acoustic seals at top
and bottom, are connected by metal piano hinges. Inside the double
shell construction, non-distorting internal pantograph units are
connected to a number of the folded leaves to provide unrivalled
stability. Aluminium leading edge profiles have magnetic strips for
positive closing with hook latch. An adjustable jamb post assembly
that needs no packing simplifies the wall fixing. Where required
shallow, load bearing floor tracks are available either surface fixed or
recessed, but both must be fixed to a level threshold. Available in a
range of finishes including melamine, laminates and veneers, with
certificated sound insulation ratings up to Rw 36dB.

Foldawall head detail
Amodern double shell concertina folding wall which closes flat, to
fill the gap between hinged folding walls and vinyl sliding-folding
partitions with a variety of options designed to provide an 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.
Sound insulation ratings up to Rw 34dB.

Simple and EffectiveFoldacord
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.
Protective heavy duty webbing sewn to outer PVC coated fabric with nylon thread, and attached to hinge valley by self locking clips
High performance acoustic fabric (2 options)
Carbon steel pantograph action hinged to aid evenness of fold when opening the partition
Leading post trolley with a ball bearingaction and smoothrunning nylon tyres
Vertical rods connected to hinges form the rigid framework
Limit tape to avoid overstretching
