1.4 PERFORMANCE REQUIREMENTS:

A. General: Design glazing system consistent with guidance and practices presented in the GANA Glazing Manual, GANA Laminate d Glazing Manual, and GANA Sealant Manual, as applicable to project. Installed glazing is to withstand applied loads, thermal stresses, therm al movements, building movements, permitted tolerances, and combi nations of these conditions without failure, including loss or glass breakage attributable to defective manufacture, fabrication, or installation;

failure of sealants or gaskets to remain watertight and airtight;

deterioration of glazing materials; unsafe engageme nt of the framing

08 80 00 - 2 system; deflections beyond specified limits; or oth er defects in construction.

B. Glazing Unit Design: Design glass, including en gineering analysis meeting requirements of authorities having jurisdic tion. Thicknesses listed are minimum. Coordinate thicknesses with fra ming system manufacturers.

1. Design glass in accordance with ASTM E1300, and for conditions beyond the scope of ASTM E1300, by a properly subst antiated structural analysis.

1.5 SUBMITTALS:

SAMPLES.

B. Manufacturer's Certificates:

1. Certificate stating that fire-protection and fir e-resistive glazing units meet code requirements for fire-resistance-ra ted assembly and applicable safety glazing requirements.

2. Certificate on solar heat gain coefficient when value is specified.

3. Certificate on "R" value when value is specified .

G. Preconstruction Adhesion and Compatibility Test Report: Submit glazing sealant manufacturer’s test report indicating glazi ng sealants were tested for adhesion to glass and glazing channel su bstrates and for compatibility with glass and other glazing material s.

1.6 DELIVERY, STORAGE AND HANDLING:

A. Delivery: Schedule delivery to coincide with gla zing schedules so minimum handling of crates is required. Do not open crates except as required for inspection for shipping damage.

B. Storage: Store cases according to printed instru ctions on case, in areas least subject to traffic or falling objects. Keep storage area clean and dry.

08 80 00 - 3

C. Handling: Unpack cases following printed instruc tions on case. Stack individual windows on edge leaned slightly against upright supports with separators between each.

D. Protect laminated security glazing units against face and edge damage during entire sequence of fabrication, handling, an d delivery to installation location. Provide protective covering on exposed faces of glazing plastics, and mark inside as "INTERIOR FACE " or "PROTECTED

FACE":

1. Treat security glazing as fragile merchandise, a nd packaged and shipped in export wood cases with width end in upri ght position and blocked together in a mass. Storage and handling to comply with manufacturer's directions and as required to preven t edge damage or other damage to glazing resulting from effects of m oisture, condensation, temperature changes, direct exposure to sun, other environmental conditions, and contact with chemical solvents.

2. Protect sealed-air-space insulating glazing unit s from exposure to abnormal pressure changes, as could result from sub stantial changes in altitude during delivery by air freight. Provide temporary breather tubes which do not nullify applicable warr anties on hermetic seals.

3. Temporary protections: The glass front and polyc arbonate back of glazing are to be temporarily protected with compat ible, peelable, heat-resistant film which will be peeled for inspec tions and re-applied and finally removed after doors and wind ows are installed at destination. Since many adhesives will attack po lycarbonate, the film used on exposed polycarbonate surfaces is to b e approved and applied by manufacturer.

4. Edge protection: To cushion and protect glass cl ad, and polycarbonate edges from contamination or foreign m atter, the four (4) edges are to be sealed the depth of glazin g with continuous standard-thickness thermoplastic rubber tape. Alter natively, continuous channel shaped extrusion of thermoplasti c rubber are to be used, with flanges extending into face sides of glazing.

5. Protect "Constant Temperature" units including e very unit where glass sheet is directly laminated to or directly se aled with metal-tube type spacer bar to polycarbonate sheet, from exposures to

08 80 00 - 4 ambient temperatures outside the range of 16 to 24 degrees C (60 to

75 degrees F), during the fabricating, handling, sh ipping, storing, installation, and subsequent protection of glazing.

1.7 PROJECT CONDITIONS:

Field Measurements: Field measure openings before ordering tempered glass products to assure for proper fit of field me asured products.

1.8 WARRANTY:

A. Construction Warranty: Comply with the FAR claus e 52.246-21 “Warranty of Construction”.

B. Manufacturer Warranty: Manufacturer shall warran ty their glazing from the date of installation and final acceptance by th e Government as follows. Submit manufacturer warranty.
