F.  FABRICATION: 

1.  Panels: Wall panels are constructed of 18-gauge, 304 Stainless Steel with a number 4 finish. Each Panel is 2” thick and pre-fabricated with exact dimensions for location within the wall. Due to installation variances, final dimensions are determined before fabrication by field measuring. (All equipment should be set in place and fully anchored prior to field measuring).

Double-Sided Panels consist of a front and back skin, both have a 90-degree form running around the perimeter. A reinforced hat form running through the center of the panel, lends added rigidity and integrity to the panels, preventing “oil canning.” Panels are filled with fire retardant glass fiber mineral wool. The back skin is attached to the front panel using internal stainless steel strips, and hidden fastening methods along the sides.  There are openings left in the back of the panels to anchor each panel to the next.  A cover plate closes this off once all panels are bolted together.   The panels are arranged with a vertical grain direction to conceal all open areas around the equipment.  Each panel shall be firmly attached to the adjacent panel using internal ¼ 20 SS hardware. 

2.  Insulation: Fire retardant mineral wool is used as an insulation in our panels.

It has an R-Value of 13. Its noise reductions add an STC of 4-12 to each panel and hold an NRC of 1, much higher than that of solid insulations. It also absorbs up to 25% more sound. It is moisture resistant and inorganic; mold cannot feed on it. It is naturally noncombustible and can withstand temperatures up to 2150F. With this we exceed stringent fire rating requirements e.g. NFPA220, ASTM E 136 

3.  C-Channel/ Anchoring Brackets: The panels are firmly attached to both the floor and existing perimeter walls using C Channel and brackets. These not only lock the panels in place but shall also conceal any clearance openings between the modwall perimeter and adjacent building walls, floors and ceiling. There shall be no visible anchoring or fastening methods on the front face of the wall.

4.  Access Doors: Shall be constructed of 18-gauge, Type 304 Stainless Steel with a #4 finish. Grain Direction shall match adjacent panels. The door is fabricated with similar methods to the modwall panels, keeping the look of the wall consistent.  All Hardware Shall be Stainless Steel. Door shall be held in place with a full-length Type 304 Stainless Steel, “Piano” style hinge.  The door shall be provided with a keyed lockset with an anti-microbial finish. The door shall have a gasketed stainless steel sweep. The door is set in an 18ga stainless steel frame.

5.  Trim Pieces: 18ga, 304 stainless steel angles.

6.  Modular walls are gasketed with metal colored silicone resistant to the growth of mold and mildew. This silicone sealant has Federal Specifications of TT-S001543A(COM-NBS), TT-S-00230 C (COM-NBS), ASTM-C-920, Type S, NS, Class 25.

G  QUALITY ASSURANCE
