Unifold Operable Walls can be specified by completing three easy steps, designed to determine the type and features required for each operation.
The Unifold Specification Sheet is provided so you can easily select the specifications for your project. When complete, either post, fax or email your specifications to Unifold. If you prefer, call one of our representatives who will be happy to assist you and provide an accurate costing.
OPTIONS TO CONSIDER:
|
STILES
|
The Aluminium panel and door stiles are designed to achieve superb sound isolation qualities. This is achieved with combination of a labyrinth principle profiles and acoustical seals, which interlock forming an airtight seal. The MDF-panel faces are protected within the aluminium frames, leaving 10mm exposed aluminium surrounds when the panels are closed.
|
|
CLOSURES
|
Every Operable Wall will need to have a closure panel, either a full height pass door or an expanding panel, which enables the panels to be separated from each other.
Full height pass door is the most common option, which will also provide an access through the wall. The door is hinged off an adjustable aluminium jamb at one end. However, with a side and remote stacking option, a full height door can be hung from another panel.
Expanding panel with a telescopic stile is another effective way of closing off the wall. With this option there is no access through the wall. A simple lever action activates the telescopic stile providing a 150mm opening, which is required to release other panels for stacking.
|
|
JAMBS
|
The ends of the opening can be fitted with an adjustable jamb, which can compensate out-of-plumb conditions by +- 10mm. Sufficient stud structure is required behind the jabms, particularly behind a door jamb, to carry the weight of a door. Alternatively, balloon type bulb seals can be used at the end of the panels, eliminating any fixtures on the perimeter walls.

HOW TO SPECIFY YOUR OPERABLE WALL
The 7000-series Operable Wall specification consists of 4 numbers, each referring to certain performance and operional features critical to a successful installation.
1st digit - Panel thickness
2nd digit - Stacking configuration
3rd digit - Acoustic horizontal seal options
4th digit - Sound rating
FIRST DIGIT: PANEL THICKNESS
|
|
All panels have a thickness of 75mm = 7
|
|
|
SECOND DIGIT: STACKING CONFIGURATION
|
CONFIGURATION |
ADVANTAGE |
TO BE CONSIDERED |
CENTRE STACK
This is the most common stacking
arrangement. For extra stability, the
panels are operated and hinged in
pairs. With a full height pass door
option, the door will open to one side
of track only, not half-half, as with
stacking of all othter panels. |
- No additional headwork required for stack end of the wall (only a straight track required). Ideal for bulkhead installations.
- Low cost
|
- Stronger structural head required due to the ability to stack ALL panels anywhere along the track (point load).
- Can accommodate up to 15 deg corners
|
SIDE STACK
The easiest way to operate panels as
they are injdividually pushed along
the track. All panels will stack to one
side of the track as they are fed into
side stack track. |
- Easy to operate.
- Point load only at the stack end.
- Can accommodate corners and columns.
|
- Extra headwork required for the stack track. (If fitted to a blukhead, a separate bulkhead is required for stack track).
|
REMOTE STACK
Similar to side stack, but panels are
moved along the track to a remote
stack away from the main track,
(into a separate stacking bay, storage
room etc) |
- Can be stored in a separate area.
- No panels seen when wall is open.
- Can accommodate corners and columns.
|
- Extra costs involved with requirements for extra tracking and headwork.
|
|
|
THIRD DIGIT: ACOUSTIC SEAL OPTIONS |
CODE NUMBER |
DESCRIPTION |
|
0
|
Fixed top and bottom seals: the most economical solution for sealing off between the panels and the floor/track. Seals can acommodate 12mm variance in floor levels due to "tear-offs" in each finger.
|
1 |
Fixed top and retractable bottom seals: mainly used when floor levels exceed 20mm (up to 25MM), but also used on very high applications, where ease of operation is most critical. Seals can be activeated manually or automatically.
|
2 |
Retractable top and bottom seals: only recommended when the track and celing are perfectly flush for specific design. Seals can be activated manually or automatically.
