5 SECTION 1 - General Information SECTION 1 - GENERAL INSTALLATION NOTES: GENERAL CONSTRUCTION NOTES Don't drop products during handling. Dropping or striking members against any solid objects will damage the finish and may cause fabricated joints and applied sealants to fail. Stack with adequate separation so materials will not rub together. Use interleaving material if needed. Cardboard wrapped or paper interleaved material must be kept dry. Store products off the ground. Protect against the elements, and damage by other construction trades. Keep material away from water, mud, and construction materials. Prevent cement, plaster or other materials from damaging the finish. Protect the erected framing by wrapping with Kraft paper or by erecting sheet plastic or canvas splatter screens. Cement, plaster, terrazzo and other alkaline solutions are very harmful to the finish. Under no circumstances allow these materials to dry on the finish or permanent staining will occur. Remove immediately with mild soap and water. All materials should be checked for quality and quantity upon receipt, Pittco must be notified immediately of any discrepancies. Check to make sure you have the required shims, supplies, sealants, and tools necessary for installation. Any material substitutions must be of equal or greater quality. Sealants must be compatible with all materials with which they have contact, including other sealant surfaces. Consult with your sealant supplier for recommendations relative to shelf life, compatibility, priming, tooling, adhesion, safety, etc. "Fastening" will mean any method of securing one part to another or to adjacent materials. These instructions will specify only those fasteners used within the system. (Perimeter or anchor fasteners are normally not specified due to varying surrounding conditions.) Glazing gaskets should be cut long to account for shrinkage. They should be installed by inserting both corners first, then the center of the gasket followed by the quarter points. Continue subdividing the opening until the gasket can be easily and completely rolled into the gasket pocket. Gaskets installed in this manner will close at the corners and will not shrink or pull back at the ends. Isolate all aluminum to be placed directly in contact with concrete with a heavy coat of bituminous paint. Isolate aluminum from incompatible materials with plastic shims, paint finish, or zinc rich primer. Any horizontals will act as collectors of infiltrated water and will direct water to the vertical pockets that will act as downspouts. Water deflectors must be installed above all lights of glass to insure that water is directed from the downspouts to the outside of the building. Sill flashing is not required in all applications, when flashing is required end dams should be utilized. Always apply a good sealant to all bearing surfaces of all weathered shear block clips to insure positive weathering. Consult sealant manufacturer for approved materials. Take field measurements BEFORE fabrication to ensure a proper fit. A minimum perimeter shim space of 3 4" is required at the head, and 1 2" sill and jambs. Joint at head may be increased to accommodate building movements and / or thermal expansion with a "T" anchor. Joint should be twice the total anticipated movement. 3

6 1. Measure The Opening: Before fabricating material, an accurate frame size should be determined by physically measuring the actual dimensions of the intended opening. Because of construction tolerances and construction practices, the actual opening may not be in total accordance with the approved shop drawings. Anchor Conditions/Locations WL Measure the width of the opening in several places to determine the minimum opening width. Measure the height of the opening in several places to determine the minimum opening height. Check level and plumb of the opening and adjust width and height measurements accordingly. 2. Determine The Frame Size: After determining the maximum rough opening width, subtract twice the allowance for perimeter jamb sealant to determine the required frame width. After determining the maximum rough opening height, subtract the allowance for perimeter sealant at the sill and the allowance for perimeter sealant at the head to determine the required frame height. 3. Determine Anchor Conditions and Locations: Review the opening conditions to determine the type of anchoring required and the location of the anchors. Assess the surrounding structure to verify that if the type of anchors shown on the shop drawings can be correctly installed. Note anchor types at each condition which will be used during installation of the wall. TYPE C (Multiple Span w/splice - Overhang) DL SPLICE WL DL WL Make sure the shop drawings reflect your notes before fabricating the frame.

33 SECTION 3 - Framing Fabrication FIBERGLASS PRESSURE PLATE SAFETY SHEET HAZARDS The grinding, drilling, sanding, cutting or other mechanical working of this product may generate dusts that could form combustible dust-air mixtures. Consult appropriate NFPA standards and local Authority Having Jurisdiction for proper protection methods and OSHA directive for combustible dust CPL Dust from grinding, cutting, or machining may act as a mechanical irritant to skin, eyes and upper respiratory system. Continuous glass filaments are not listed as a carcinogen by the IARC. WASTE DISPOSAL Dispose in accordance with Federal, State, and local regulations. The primary method of disposal is in a municipal or industrial landfill. EXPOSURE CONTROLS / PERSONAL PROTECTION If airborne fiberglass concentrations of the dust from grinding, cutting or machining exceeds permissible exposure levels, the use of a disposable mask in accordance with OSHA respiratory protection requirements designed for nuisance dusts is advisable. Use a mechanical dust collector to capture dust from grinding, cutting or machining operations at point of generation. Use goggles or safety glasses when grinding, cutting or machining Use of long sleeved shirts fitting loosely at the neck and wrists, long pants, gloves and good personal hygiene will maintain comfort when grinding, cutting or machining.

41 SECTION 4 - Sealant and Erection SECTION 4 - SEALANT AND ERECTION PROCEDURES In all the following details the perimeter sealant should be applied BEFORE THE FACE AND RETAINER ARE INSTALLED. However, the area between the outboard edge of the sill closure plate and the vertical retainer must be left open to allow weep water drainage. Standard system splice joint including 2 sided EFG horizontals: Backer rod at vertical expansion joint should be approximately the same length as the metal splice and completely covered with sealant. When the vertical mullion has been properly located and anchored, apply a non-hardening, non-skinning sealant at the 1/2" nominal expansion joint to the entire front surface and return on each side approximately 1/2". Apply enough sealant to front side of mullion to make a sealant reservoir so when mullion expands, sealant will not be overstretched. EFG 2 sided vertical, vertical splice joint: At the 1/2" vertical expansion joints this area must be sealed with a low modulus silicone compatible to the silicone used to structurally bond the glass to the mullion. Special EFG notes: On EFG mullions where "sealant" is in contact with the silicone sealant this "sealant" must be silicone compatible. Exterior horizontal faces crossing structural silicone verticals may be continuous across these verticals but must have an expansion joint at the expansion vertical wide enough to accommodate horizontal expansion. Of course when this is done the entire face will have to be removed during any exterior reglaze operations and is not recommended. When applying structural silicone to bond glass to mullion and weatherseal silicone to seal between lights of glass, it is recommended that masking tape be applied either side of this silicone joint before applying silicone. Silicone must be tooled into the joint and immediately after have tape removed before silicone begins to "Skin Over". Of course all glass and metal edges must be cleaned immediately before applying silicone as per silicone manufacturers' recommendations. S1

Shim sill anchor to height and fasten anchor keeping mullion on control line 6. Plumb mullions and use the intermediate anchor clip as a drill template and drill through mullion using a drill bit of the appropriate size for anchor. Attach anchor to structure by method shown on shop drawings and or structural calculations. VERTICAL INSTALLATION 1V. Set 2nd jamb mullion or 2nd ladder over splice. For dynamic splice shim 1 2" between ends of mullions at splice to hold gap. 2V. Plumb to intermediate anchor and fasten clip to mullion and structure then remove shims. 3V. Repeat vertical process up to top of opening. 4V. Remove head from top ladder. 5V. Attach top of frame with 'T' anchor. 6V. Drop in head horizontal making sure to bed in sealant. 7. Drop in sill horizontal to finish the first ladder making sure to bed in sealant. 8. Starter mullion or ladder is now stable so either continue installing horizontally or vertically. HORIZONTAL INSTALLATION 1H. Attach intermediate horizontals to the jamb mullion or ladder 2H. Assemble second mullion or ladder to other end of intermediate horizontals 3H. Shim and anchor sill horizontal 4H. Attach intermediate anchor 5H. Drop in sill horizontal 6H. Continue horizontal process until ending jamb or final ladder is installed. NOTE: Plan installation so that last bay of loose horizontals are notched to slide over shear blocks. NOTE: If welding clips to steel structure make sure to protect framing from weld splatter. Alternatively intermediate anchors may be applied first. Leave 1 4" minimum clearance from clip to mullion to allow room to insert mullions or ladders between anchor clips. S9

50 SECTION 5 - Glazing GASKET INSTALLATION 1. Interior Gaskets: Cut the vertical gaskets 1" longer than the D.L.O. Insert the gasket in the vertical gasket reglet, centered on the opening in the frame. Cut the horizontal gaskets 1" longer than the D.L.O. Insert the gasket in the horizontal gasket reglet between the previously installed vertical gaskets. To avoid displacing the vertical gaskets, insert both ends of the horizontal gasket first and then continue inserting the rest of the gasket working towards the center of the opening in the frame. Seal the gasket corners for high performance installations. During glazing apply a small bead of sealant to the joints of the vertical and horizontal gasket. (See Figure 29) 2. Exterior Gaskets: The shop will leave gaskets long to account for any stretching that may occur. Field cut the exterior gaskets the same length as the retainers into which they will be installed except for ends at a splice and horizontal gaskets w/ vertical SSG. Press the gaskets into the gasket reglet until fully seated. For end below a splice cut gaskets 1" short; for end above splice cut gasket 1" long. For vertical SSG horizontal; gaskets on top of retainer should be 1 2" long to meet at centerline and gaskets on bottom of retainer should be same length as retainer to leave gap for drainage 1/2" SEAL HERE FOR ENHANCED PERFORMANCE FIG 29 - INTERIOR GASKET INSTALLATION G1

51 SECTION 5 - Glazing SETTING BLOCK INSTALLATION 1. Setting blocks are intended to be located on the tongue of the horizontal at the quarter points of the D.L.O. If the structural calculations require the setting blocks to be moved towards the corners of the opening in the framing, they may be moved but the center of the setting block length must never be closer than 8" from the ends of the horizontal. 2. Place the or setting blocks on the horizontal tongue aligned per the detail below. (See Figure 30) 3. When setting glass on the setting blocks, be sure not to move or dislodge the setting blocks. The setting blocks must be fully under the glass lite(s) and provide complete support for the glazing infill. SETTING BLOCK 3 32 " 1/4 LENGTH LENGTH <8" FIG 30 - SETTING BLOCK INSTALLATION G2
