SECTION 08 80 00
GLAZING
PART 1 - GENERAL
1.1 DESCRIPTION:
A. This section specifies the following:
1. Glass.
2. Glazing materials and accessories for both factory and field glazed assemblies.
1.2 RELATED WORK:
A. Factory glazed by manufacturer in following units:
1. Doors: Section 08 11 13, HOLLOW METAL DOORS AND FRAMES, and Section 08 14 00, WOOD DOORS.
1.3 LABELS:
| A. | Temporary labels: |
| 1. | Provide temporary label on each light of glass identifying manufacturer or brand and glass type, quality and nominal thickness. |
| 2. | Label in accordance with NFRC label requirements. |
| 3. | Temporary labels are to remain intact until glass is approved by Contracting Officer Representative (COR). |
| B. | Permanent labels: |
| 1. | Locate in corner for each pane. |
| 2. | Label in accordance with ANSI Z97.1 and SGCC label requirements. |
| a. | Tempered glass. |
1.4 PERFORMANCE REQUIREMENTS:
| A. | General: Design glazing system consistent with guidance and practices presented in the GANA Glazing Manual, GANA Laminated Glazing Manual, and GANA Sealant Manual, as applicable to project. Installed glazing is to withstand applied loads, thermal stresses, thermal movements, building movements, permitted tolerances, and combinations 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 engagement of the framing system; deflections beyond specified limits; or other defects in construction. |
| B. | Glazing Unit Design: Design glass, including engineering analysis meeting requirements of authorities having jurisdiction. Thicknesses listed are minimum. Coordinate thicknesses with framing system manufacturers. |
| 1. | Design glass in accordance with ASTM E1300, and for conditions beyond the scope of ASTM E1300, by a properly substantiated |
2. Maximum Lateral Deflection: For glass supported on all four edges, limit center-of-glass deflection at design wind pressure to not more than the structural capacity of the glazing unit, the threshold at which frame engagement is no longer safely assured, 1/100 times the short-side length, or 19 mm (0.75 inch), whichever is less.
1.5 SUBMITTALS:
A. In accordance with Section 01 33 23, SHOP DRAWINGS, PRODUCT DATA, AND SAMPLES.
B. Manufacturer's Certificates:
| 1. | Certificate stating that fire-protection and fire-resistive glazing units meet code requirements for fire-resistance-rated assembly and applicable safety glazing requirements. |
| 2. | Certificate on solar heat gain coefficient when value is specified. |
| C. | Manufacturer Warranty. |
| D. | Manufacturer's Literature and Data: |
| 1. | Glass, each kind required. |
| 2. | Elastic compound for metal sash glazing. |
| 3. | Glazing cushion. |
| 4. | Sealing compound. |
1.6 DELIVERY, STORAGE AND HANDLING:
| A. | Delivery: Schedule delivery to coincide with glazing 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 instructions on case, in areas least subject to traffic or falling objects. Keep storage area clean and dry. |
| C. | Handling: Unpack cases following printed instructions 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, and 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, and packaged and shipped in export wood cases with width end in upright position and blocked together in a mass. Storage and handling to comply with manufacturer's directions and as required to prevent edge damage or other damage to glazing resulting from effects of moisture, condensation, temperature changes, direct exposure to sun, other environmental conditions, and contact with chemical solvents. |
| 2. | Protect sealed-air-space insulating glazing units from exposure to abnormal pressure changes, as could result from substantial changes in altitude during delivery by air freight. Provide temporary breather tubes which do not nullify applicable warranties on hermetic seals. |
| 3. | Temporary protections: The glass front and polycarbonate back of glazing are to be temporarily protected with compatible, peelable, heat-resistant film which will be peeled for inspections and reapplied and finally removed after doors and windows are installed at destination. Since many adhesives will attack polycarbonate, the film used on exposed polycarbonate surfaces is to be approved and applied by manufacturer. |
| 4. | Edge protection: To cushion and protect glass clad, and polycarbonate edges from contamination or foreign matter, the four (4) edges are to be sealed the depth of glazing with continuous standardthickness thermoplastic rubber tape. Alternatively, continuous channel shaped extrusion of thermoplastic rubber are to be used, with flanges extending into face sides of glazing. |
| 5. | Protect "Constant Temperature" units including every unit where glass sheet is directly laminated to or directly sealed with metaltube type spacer bar to polycarbonate sheet, from exposures to ambient temperatures outside the range of 16 to 24 degrees C (60 to 75 degrees F), during the fabricating, handling, shipping, storing, installation, and subsequent protection of glazing. |
