Guide Specifications For Moduflex^® Operable Walls

Part 2.  Products

2.1 OPERABLE WALLS shall be manufactured by Panelfold, Inc., Miami, Florida, U.S.A. and installed by an authorized representative of the manufacturer in openings prepared by others to Moduflex^® Series (specify: 800; 600; or 400) requirements.

2.2 OPERATION shall consist of a series of manually or electrically operated flat panels, top supported. Top and bottom seals shall be as specified in paragraph 2.8.

2.3 PANEL CONFIGURATION shall be as follows for areas indicated on the plans:
2.3.1 MODELS 810/610/410 shall be comprised of a series of individual panels, side or remote stacking (located in rooms). Operation of the panels shall be (specify: Preprogrammed; or MultiDirectional). Final closure shall be effected by (specify: jamb-hinged single or bi-fold panels; expandable or expandable fly-panels; or jamb hinged communicating panels).
2.3.2 MODELS 820620/420 shall be comprised of panels hinged in pairs and center stacking (located in rooms). Final closure shall be effected by (specify: single or bi-fold panels; expandable panels; or jamb-hinged communicating panels.
2.3.3 MODELS 840/840 GWE/640 shall be comprised of a series of continuously-hinged panels, center stacking, electrically operated. Final closure shall be effected by (specify: jamb-hinged half panels; offset jambs; or seal thru pocket doors). Two spring loaded, center off, key switches, wired in series shall be installed for safety viewing by two operators on station during entire operating sequence.

2.4 PANELS:
2.4.1 SERIES 800 shall be 4” (102mm) thick, one piece, all steel construction. Continuous steel panel faces shall be invisibly welded to minimum 14 gauge (1.90mm) one-piece steel frames. Horizontal or vertical spliced frames or faces shall not be permitted. Interlocking vertical panel edges shall be made of steel.
2.4.2 MODEL 840GWE shall be 3” (76mm) thick, one piece, all steel construction with lightweight, impact resistant honeycomb core. Continuous steel panel faces shall be invisibly welded to minimum 16 gauge (1.62mm) one-piece steel frames. Horizontal or vertical spliced frames or faces shall not be permitted. Interlocking vertical panel edges shall be made of steel.
2.4.3 SERIES 600 shall be 4” (102mm) thick and nominally 49” (1245mm) wide. Panel faces shall be laminated to metal frames. Panels shall have appropriate internal insulation to achieve specified STC. The tops of the panels shall be reinforced to support suspension components.
2.4.4 SERIES 400 shall be 3” (76mm) thick and nominally 49” (1245mm) wide. Panel faces shall be laminated to metal frames. Panels shall have appropriate internal insulation to achieve specified STC. The tops of the panels shall be reinforced to support suspension components.
The vertical edges of the panels shall not require trim thus minimizing the appearance of the vertical joining of the Sheer-Look® panels.

2.5 PANELS shall be factory surfaced with one of the following Class A Flame Spread rated materials (colors to be selected from manufacturer’s standards): Vinyl wall covering, (specify: Type I; or Type II); Ribtex^® vertical-rib wall carpeting; Woventex^® panel fabric; Maharam Tekwall^® 1000^© panel fabric; Customer’s Own Material; or unsurfaced, prepared for field surfacing by others.

2.6 HANGING WEIGHT of panels shall not exceed 12 lbs./ft² (58.6Kg/m²).

2.7 ACOUSTICAL RATING of panels as tested by an independent acoustical laboratory in accordance with ASTM E90-85 test procedures in a full scale 14’0” (4267mm) by 9’3” (2819mm) shall be (specify: STC 54; STC 52; STC 50; STC 49; or STC 47; STC 42; STC 38; or STC 33). Optional N.R.C. .90, (Series 800 only) STC 50 panels shall be supplied where indicated on the plans.

2.8 SOUND SEALS shall be as follows:
2.8.1 VERTICAL SEALS between panels shall consist of deep nesting, universal interlocking ESP bronze steel astragals incorporating continuous vinyl acoustical seals. Vertical astragal vinyl seals shall be installed on the outboard edges of the panel skins in a double row with an acoustical labyrinth.
2.8.2 HORIZONTAL TOP seals shall be (specify: continuous contact extruded vinyl shapes; clearance type, manually actuated; or clearance-type, automatically actuated).
2.8.3 HORIZONTAL BOTTOM seals shall be (specify: clearance-type automatically actuated; or 1-1/2” (38mm); 2-1/2” (64mm); or 5-1/2” (141mm) manually actuated at waist height on panel edges).
Downward pressure of all clearance type bottom seal mechanisms shall assure an acoustical seal and resist panel movement.

2.9 PANELS shall be hinged with manufacturer’s standard butt-type hinges.

2.10 POCKET DOORS where indicated on the plans shall be manufactured of the same materials as the panels. Hinges shall be standard butt-type.

2.11 OPTIONAL U.L.^® ONE HOUR fire rated Series 800, only, walls shall be supplied where indicated.
