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.

GLAZING 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 sh all 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 shall be temporarily protected with compati ble, peelable, heat-resistant film which will be peeled for inspections and re-applied and finally removed after doors and windows are installed at destination. Since many adhesives will attack polyc arbonate, the film used on exposed polycarbonate surfaces shall b e approved and applied by manufacturer.

4. Edge protection: To cushion and protect glass cl ad, polycarbonate, and Noviflex edges from contamination or foreign ma tter, the four edges shall be sealed the depth of glazing with con tinuous standard-thickness Santoprene tape. Alternatively, continuou s channel shaped extrusion of Santoprene shall 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 e xposures to ambient temperatures outside the range of 16 to 24 C, during the fabricating, handling, shipping, storing, installat ion, and subsequent protection of glazing.

1.7 PROJECT CONDITIONS

Field Measurements: Field measure openings before ordering tempered glass products. Be responsible for proper fit of fi eld measured products.

GLAZING 08 80 00-4
