Glazing fabrication Structural glazing.

At the request of the Project Director/COR, a Government representative shall be allowed access to the Contractor’s facilities and those of major suppliers at any time to monitor QC procedures. Make available all QC Program records upon request.

Quality Inspections:

Inspect each glazing layer (see Part 2 of this Section) thoroughly for observable edge damage, face imperfections, optical defects, or distortion prior to assembly. Optical defects are defined as follows:

ASTM C 1036 for flat glass.

ASTM C 1048 for heat strengthened glass.

ASTM C 1172 for laminated glass.

ASTM C 1349 for flat glass clad polycarbonate.

ASTM C 1376 for pyrolytic and vacuum deposition coatings on glass.

Conduct routine in-house staff training to ensure awareness of factors that affect polycarbonate cracking, including environmental stress cracking, creep, and non-compatible materials.

Quality Control inspection documents shall incorporate:

Detailed description of glazing layup.

Acceptance criteria, optical defect limitation tables, industry terminology for defects, means of detection, and other requirements of referenced standards, applied to entire layup.

IDENTIFYING DEVICES

Provide fritted or etched label within glazing panel layers with the following information: manufacturer’s name, date of manufacture, DOS Code number, and Glazing Layup number, and glazing panel dimensions. Locate label in lower right corner on the protected side and visible after glazing is framed and cladded.

Provide “ATTACK SIDE” removable label on attack side of glazing panel in very conspicuous location.

DELIVERY, STORAGE, AND HANDLING

Protect laminated security glazing panels 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."

Treat security glazing as fragile merchandise, and packaged and shipped in cases or racks, not comprised of wood manufactured with phenols, and blocked together in a mass. Do not use plastic or polyethylene sheeting, or extruded polystyrene. Storage and handling shall 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, ground contaminants, and contact with chemical solvents.

Protect sealed-air-gap insulating glazing panels from exposure to abnormal pressure changes, as could result from substantial changes in altitude during delivery by air freight. When windows will be installed in a location that has a different above sea level elevations than where they were manufactured and as a result will cause the glass to deflect, provide temporary capillary/breather tubes which do not nullify applicable warranties on hermetic seals.

Temporary protections: Security glazing shall be temporarily protected with manufacturer-applied compatible, peelable, heat-resistant film. This film shall be peeled by Contractor for inspections, and re-applied by Contractor, in accordance with manufacturer’s recommended procedures.

Edge protection: To cushion and protect glazing edges from contamination or foreign matter, the four edges shall be sealed the depth of glazing with continuous standard-thickness TPU or Santoprene tape. Alternatively, continuous channel shaped extrusion of Santoprene shall be used, with flanges extending onto faces of glazing.

Conduct thorough visual inspections of the glazing prior to packaging.

Pack replacement glazing panels with no more than two panels per crate. Provide replacement glazing tape, setting blocks, spacers, and other required accessories, packed in the same crate as the glazing panels.

Include packaging that clearly lists non-compatible materials for temporary protection during construction and cleaning. Include this information on the manufacturer’s website, product literature, warranties, and other documents provided to the construction team and building occupants.

Store materials in a dry, well ventilated location. Keep handling of materials to a minimum, and carefully protect materials from soiling and from condensation and other harmful moisture. Provide vapor-permeable materials for protection during shipping. Do not trap moisture within or adjacent to windows.

Conduct thorough visual inspections of glazing before installation. Inspections should include removal of glazing stops, if applicable. Do not install glazing with cracks in the polycarbonate.

SPECIAL PRODUCT WARRANTIES

Government will certify that it will continue proper maintenance and non-exposure to destructive forces exceeding those forces indicated to be satisfactorily resisted by panels without incurring permanent damages. Defective panels are defined to include delamination, change of optical characteristics, glass/plastic breakage or cracking, weathering, change of light/heat/solar transmittances, abnormal aging, and, for insulating panels, loss of hermetic seal.

Warranty Period: 5 years for delamination, 10 years for all other defects.
