General


Q: When stored away, does SKYFOLD operable walls take up any floor space?

A: When not in use, SKYFOLD rests in its folded position, in the ceiling, requiring absolutely no floor space. In fact, in many installations, it is not even possible to tell if and where the SKYFOLD walls are located, until they are operated.

Q: What type of structural support is required for SKYFOLD operable walls?

A: SKYFOLD operable walls takes less structural steel than conventional operable walls since it is a static load. SKYFOLD walls’ loading on the structural steel is always evenly distributed across its width. SKYFOLD walls’ entire weight is never concentrated as a single point load on the structure. SKYFOLD operable walls weighs approximately 6.0 - 9.4 lbs/ft² (29.4 - 46 kg/m²), significantly less than conventional operable walls.


Q: How much ceiling room is required to store SKYFOLD operable walls?

A: SKYFOLD operable walls is remarkably compact. In many instances, depending on the height of the wall, a folding ratio from 1:5 to 1:10 is achieved. This remarkable feature allows SKYFOLD operable walls to be stored in most existing ceiling spaces.

Q: What is the difference between an operable wall’s acoustic rating (the complete system rating) and its panel’s acoustic rating?

A: The difference between an operable wall’s acoustic rating and its panel rating can be significant. In general, panel ratings are based on tests performed on one or more panels that are fixed in place and that do not necessarily have some or all of the panel joints and associated gaskets and seals that the fully operable system has. As such, the Panel acoustic ratings do not represent the actual fully operable system rating. Similarly, a test of a manual system cannot accurately represent the ratings achievable by a fully automatic operable system using the same panel construction as its “equivalent” manual system.

Skyfold operable wall system tests are of fully automatic Skyfold operable walls that are installed and tested within an independent and accredited lab’s, standard steel frames in accordance with ASTM E90 (North America) and ISO 140-3 (Europe). For the ratings to be legitimate the tested operable wall must be identical in construction and functionality as the ones manufactured for the market. They include all fixed acoustic seals and gaskets, mechanical acoustic seals, mechanisms, etc. Also, for the test specimen to be designated an operable wall it must be opened and closed no less than 5 times without further adjustments prior to testing as per the ASTM E90 test standard for operable walls.

Q: What finishes are available for the SKYFOLD Classic operable walls?

A: Our finishes include, but are not limited to vinyl, fabric, stainless steel, customer supplied materials, wood veneer, plastic laminates, et. The finish cannot exceed 1/8'' (3mm) thickness. For standard design criteria, the finish cannot exceed 0.111 pounds per square foot (0.542 kgs/m²). Heavier material will have to be approved by Skyfold. Our finishes are "railroaded" onto our panels, applied horizontally, in one piece, along the panel length, rather than vertically as is the typical application for wall finishes.

Standard SKYFOLD Classic operable walls are 11 3/4" (300mm) thick with two independent planes of steel panels separated by a 10 1/4" (260mm) air space that creates an anechoic chamber. It also has 1½" (38mm) insulation on the back of each panel. The combination of these elements creates an exceptional sound barrier that must be heard to be believed. SKYFOLD Classic operable walls have been approved by many top architectural firms in the world for use in spaces where sound control is critical.

The Skyfold® Classic NRC™ is not only designed to stop sound but also absorb sound.


Q: Do the SKYFOLD Classic operable walls require any wall or floor tracks?

A: Part of the beauty and elegance of the SKYFOLD Classic operable walls is that they do not require any floor or wall tracks. All acoustical components are integrated into the wall. Once the SKYFOLD Classic operable wall is in the down position, acoustical seals automatically engage against the floor and fixed walls.


Q: What types of safety features do the SKYFOLD Classic operable walls provide?

A: All SKYFOLD operable walls are equipped with two switches; a key to activate the system and two push buttons to operate the system. These switches are wired in series to ensure they are operated simultaneously. When either or both push buttons are released, the wall stops immediately, without coasting. SKYFOLD Classic operable walls are also equipped with a continuous pressure sensing strip on the bottom leading edge of the wall. If this sensing strip comes in firm contact with an object, power will be cut to the system and it will then automatically reverse direction and ascend for approximately 3 seconds to clear the obstruction. Normal operation of the system can resume once the obstruction has been removed.
