Bildspec Series 100 Acoustic Operable Wall

The acoustic operable wall shall be Bildspec Series 100. Note: the manufacturer shall guarantee that the operable walls are of like construction to those tested to AS 1191: 2002 by an independent Australian Acoustic Laboratory. The walls shall be installed by an authorised representative of the manufacturer and shall consist of top-supported, manually operated panels that can be linked together to form a sound retardant closure. No floor tracks are permissible.

Bildspec Series 100 Operable Walls are available in two frame types:

1. Standard Stile: (S) with a trim that consists of a 9mm wide perimeter frame around the 100mm thick panel.

3. Min/Max widths

Maximum Panel Width: 1200m

Minimum Panel Width: 600mm

Maximum Height: 6000mm

There are 3 standard stacking types available:

C: CENTRE Stack

S: SIDE Stack

R: REMOTE Stack

Centre Stack

A single straight line of track where the panels turn and stack perpendicular to the track. The carriers/trolleys are fitted centrally to each panel and, when stacked, 50% of the panel is positioned either side of the centreline of (perpendicular to) the head track. There is no separate stack track, instead the panels fold away on the main run of track to one or both ends. Please note the head track will need to be supported continuously along the full length of the track by either a suitable overhead concrete slab or a steel beam. This is the simplest and most cost-effective way to stack away your panels. This system typically has the panels hinged in pairs for stability. For Centre Stack systems, Bildspec’s ‘Number One Track and Trolleys’ (each trolley has 4 x vertical bearing wheels) enable the end user to glide the panels away and transform the space as required.

Side Stack

There is a main, straight line of track, with the stacking area/tracks off to one side of the track only (looks like an ‘h’ shape/configuration). The panels run along the main line of track and turn perpendicular to the track as they approach the stack bay track. The carriers/trolleys move 95% to the side of the centreline of the head track, with only one carrier/trolley staying on the main line of the track (the other trolley is diverted to the stack bay track). Please note the head track will need to be supported continuously along the full length of the main track and (stack bay tracks) by either a suitable overhead concrete slab or a steel beam.

*For Side & Remote Stack options, Bildspec offers two types of tracking systems, both with diverters, where possible, to guide the panels into/out of the stack bay:

i. our premium ‘Number One Track and Curves’

OR

ii. our more cost-effective ‘Number Two Track and Rollers’ which incorporates high and low rollers.

Remote Stack

There is a main, straight line of track, with the stacking area/tracks completely off to one side of the track only (looks like a one-handed trident shape/configuration). The panels run along the main line of track and turn perpendicular to the track as they approach the stack bay, with both carriers/trolleys stacking 100% off the centreline of the head track, normally stacking into a pocket recess or stacking bay.

Bildspec acoustic operable wall systems offer several seal configuration options, dependant on the site conditions and the application. In most instances we recommend Type 4 Seals (see below).

Type 1

Our basic offering being a dual line of fixed triple finger sweep seals top and bottom, which can be trimmed to the floor. These are a cost-effective option, however they can cause friction when the panels travel over the floor’s high points which in turn makes the panels harder to move.

Type 2

Our recommended and standard offering of dual line fixed triple finger sweep seals at top and mechanical retractable bottom seals. This assists the friction free movement of the panel offered by the retracting bottom seal. Furthermore, with a seal travel of

35mm, panels are able to accommodate more inconsistencies in undulating floor levels.

Type 3

Where requested, Bildspec also offers mechanical retractable seals to both the top and bottom of the panels. Please note that acoustic testing has shown that this arrangement generally performs the same as Type 2, above.

Types 4 & 5

For higher acoustic applications (e.g. Rw49 and above), Bildspec suggests a combination of fixed dual line triple finger sweep seals plus mechanical retractable seals to the bottom with either fixed or retractable seals to the top. This arrangement combines the manoeuvrability benefits of retracting seals while providing a superior sound barrier.

1. Sweep / Sweep
2. Sweep / Retractable
3. Retractable / Retractable
4. Sweep / Sweep and Retractable
5. Retractable / Sweep and Retractable

Closure Type

An acoustic wall with interlocking stiles requires a gap to be created to stack or close up the wall. We can create this gap in 2 ways depending on your project’s requirements:

D: DOOR FULL HEIGHT

X: EXPANDING PANEL

Expanding Panel

This method has a telescopic section that mechanically moves in and out, to “break” the wall down or close it off, however it does not allow for pedestrian access through the wall. This method has the best acoustic properties and adds extra rigidity to the wall system when it is in place. It is operated by a removable handle which means it cannot be operated by people without the required key.

Full Height Door Panel

Generally hinged off the wall at the stacking end (but can be hinged from another panel), this closure type allows not only to “break” the wall down or close it off, but also allows pedestrian access through the wall. This access can be designed to provide DDA compliance. (Disability Discrimination Act requirement).

Portal Panel (Full Height)

This is generally hinged off the adjacent panel at the stacking end (but can be hinged from the wall in some cases), this closure type allows only to “break” the wall down or close it off. I does not allow for pedestrian access.

Bildspec’s range has been tested to Australian Standard AS1191-200 (R2016) and AS/NZ ISO 717-1 (20040).  The following is a guide to selecting what is appropriate for your project from our range:

42 Rw – Normal speaking voices intelligible, generally suited to lower end applications where acoustic control is not required and the operable wall is to act more like a physical divide.

45 Rw – Normal speaking voices somewhat intelligible, you can understand some words and tonality. Suited to applications like school classrooms (EFSG standard), smaller 4 – 6 people meeting rooms, church halls and aged care facilities.

47 Rw – Normal speaking voices barely intelligible, suited to applications like 6 – 10 people meeting rooms, school halls, church halls and aged care facilities

49 Rw – Raised voices barely intelligible, suited to applications such as boardrooms, larger 8 – 12 people meeting spaces, smaller conference centres and hotel function rooms.

52 Rw – Raised voices unintelligible, and amplified sound is controlled, at the high end of the frequency range this is used in large 12 – 20 people training rooms, board rooms, conference centres, hotel function rooms, lecture theatres, convention centres and spaces/rooms where a high level of sound attenuation is paramount.

Select from: 

• Nylex Flexiclad Vinyl Laminate
• Wood Veneer
• Front Runner™ Fabric
• Plastic Laminate
• Prepared for on-site painting by others
• Or specify any suitable vinyl or textile wallcovering

• Inset Pass Door
• Full Height Pass Door
• Windows
• Pinboards, inset or full height
• Chalkboards with recessed chalk pockets
• Magnetic White Marker Boards

Approximately 30-45kg per square metre depending on sound rating. 

Bildspec, in conjunction with a testing lab, performed a variety of pull tests on their complete systems to ascertain the maximum failure load of their track and trolley systems when installed. 

Using a 200kN testing machine, we loaded the systems up at 5mm/min to produce analytical graphs for our consulting engineers to calculate the SWL for our complete installed system. 

The engineers calculated the SWL using factors of safety and in conjunction with AS/NZS 1170.0 - 2002/ Amdt 2011 Structural Design Actions - Part: 0 general principles, and AS/NZS 1170.1 - 2002/ Amdt 2011 Structural Design Actions - Part: 1, permanent, imposed, and other actions. 

Bildspec completed this certification to make sure our systems were fir for purpose and will perform correctly every day of the year.
