failure, undue stress on members or anchors, and other detrimental effects.
2. Provide tight joints and effectively seal component parts of panels and their joint with contiguous work against water leakage and air infiltration. Water leakage is defined as the appearance of the uncontrolled water, other than condensation, on any inboard part of panels, either during testing or under actual weather conditions.
E. PANELS - GENERAL:
1. All aluminum panels shall be constructed to consist of a formed .040” Anodized aluminum face, laminated to a 1” DOW Extruded Polystyrene core and formed .032” Mill Finish Aluminum backface. The components shall be laminated into one monolithic unit. The adhesive used in lamination shall be permanently elastic-type neoprene rubberbase industrial contact adhesive, and shall be applied to 100% of all surface areas to be laminated using an automatic four-gun reciprocator. Adhesive bonding strength shall be equal to or better than the internal bond strength of any of the component materials. Formed pan shape back shall fit inside formed pan shaped face with one part silicone sealant applied to perimeter of panel and each corner to provide a weather- tight seal against any moisture intrusion to the interior of the panel. Face pan shall be mechanically riveted to back pan at panel edges. Thickness of finished panels to be 1” Nominal Panel Thickness with a tolerance of +1/16”.
2. Panel face shall be formed from .040” anodized aluminum and back pan shall be .032” mill finish aluminum.
3. Core material shall be 1” DOW Extruded Polystyrene.
4. Sealant shall be DOW Corning 999 one part silicone building sealant. Sealants must meet Fed. Specification TTS-00230C Type II Class A.
F. METAL PROTECTION:
1. Finish on face shall be protected by strippable vinyl masking during manufacture, delivery, storage and installation of panels.
Follow manufacturer’s instructions with regard to removal of masking. Backface metal shall be mill finish unless specified otherwise.
G. PRODUCT HANDLING:
1. Panels shall be unloaded and stored in a dry space with proper blocking materials and covers to prevent damage until erection is started. Panels shall be stored off ground (so as to prevent condensation from forming between panels or sections of panels).
H. INSTALLATION:
1. All panels may be installed with back fastened clips or in a fixed window frame system as shown on drawings. Comply with panel manufacturer’s instructions and recommendations for installation, as applicable to project conditions. Install panels and other components of the work securely inplace, with provisions for thermal/structural movement.
2. Set panels level, plumb and true to line, with uniform joints. Use only types of equipment, ropes, wedges, spacers, shims and other items during erection which will not stain or mar the finish of units.
3. Exposed surfaces and edges shall be kept clean and free from sealants, metal cuttings, hazardous burrs, and other foreign materials. Stained, discolored, or damaged panels shall be removed from the site.
4. Perform all caulking operations to completely seal metal to metal contact surfaces of wall panel joints using DOW Corning 795 silicone building sealant.
I. CLEANING AND PROTECTION:
1. Damaged Units - Replace panels and other components of the work which have been damaged or have deteriorated beyond successful repair by means of finish touch-up or similar minor repair procedures.
2. Cleaning - Leave panels free from dirt, markings, scratches, dents, warpage and other damage. Remove sealants from exposed surfaces before sealant cures. Do not use abrasives, caustic or acid cleaning agents in cleaning surfaces of panels.
