Optional Stacking Configurations

For a "dynamic" look at various stacking configurations, click here to view our Special Folding Configurations Floor Plan Line Animations. To see some of these options in 3-D, click here. Below are descriptions of our optional stacking configurations.

Center Pivot Option - SL45 and WD65

When the width of stacked panels on the inside or the outside is a concern, the center pivot option reduces this problem by centering the stacked panels below the head jamb with almost equal protrusion to the inside and the outside. This is accomplished by placing the running carriages at the center of the panel instead of at the corners of the panels. Some limitations are that the end panels will need to be about half the width of the other panels, use of swing panels is limited and the maximum panel sizes possible are smaller. There will also be 2 point locking bolts and handles on almost all the panels.

To be able to support the panels, the upper rail would generally need to be wider than the standard upper rail width. Use of half width panels can be avoided by using unhinged panels (panels not hinged to a side jamb). Unhinged panels have to be an odd amount.

Use of the center pivot option is generally not recommended as the operation of the panels is not as smooth as a system with panels folding inward or outward.

Shown below are elevation drawings and horizontal cross-section schematics of some possible configurations.

Maximum panel height: 8'2" (2500 mm) Maximum panel width: With Insulated glass 2'7"(800 mm) With Single Glazing 3'3" (1000mm)

Unhinged Paired Panels

In configurations with even number of panels on one or both sides, pairs of panels need not be hinged to a side jamb or other panels.   Flexibility in folding in any direction or position along the track can be achieved.  This is achieved by having sets of running carriages at both outside corners of a pair of panels or multiple of pairs of panels. Click here to see this in action in our animations.

Below are examples of some possibilities with inward opening units. Please note that units with unhinged paired panels may not be as weather resistant as standard units.

Inward-Outward Panel Systems

Below are elevation drawings and horizontal cross-section schematics of possible configurations for models with majority or panels folding to right with the inward opening panels on the right. Similar configurations are possible for models with majority of panels folding to right with the outward opening panels on the right and models with majority of panels folding to left with the inward opening panels or outward opening panels on the left.

"A" denotes outswing panels and "I" denotes inswing panels.

Please note that the width of panels that are inward opening can be different from the width of panels that are outward opening.

Angle Options

For certain configurations for each applicatable system, a 90 degree or a 135 degree angled turn of the head and sill is possible. Create dramatic, unique openings by opening two corners of a room without the need of a corner post.  Click here to see an example of a 90 degree unit, or a 135 degree unit.

Please note that angled units may not be as weather resistant as standard straight units.

Segmented Curves

Possible with the SL45 and WD65 systems, are changes in direction or angle of the head jamb and sill up to 45 degress between each panel, pair of folding panels, or a series of panels such that with multiple connections, the unit can have segmented curves. Click here to see one example of a segmented unit.

Limitations as compared to straight units are as follows:

1. A segmented curve unit is not as weather resistant and will not withstand the same structural load.
2. Installation is more complicated and past experience in installing folding systems is recommended.
3. Besides frame dimensions, precise angles or radius need to be provided.
4. There are limitations as to which configurations are possible.
5. Costs are substantially more than standard straight units.
