SKYLIGHT PANELS
**************************************************************************
NOTE: A polyvinyl fluoride film coating may be
specified for the exterior surface of skylight
panels when longer wearability is considered
necessary. For fire rated construction, panels with
fire ratings consistent with the overall
construction of the building should be specified.
Retain appropriate bracketed statements and
corresponding paragraphs below and delete the others.
The designer must consider the differences and
performance characteristics of the two materials:
glass-fiber reinforced polyester and extruded
cellular thermoplastic polycarbonate before making
the selection to meet specific project requirements.
**************************************************************************
Skylight panels shall be fabricated of [glass-fiber reinforced polyester]
[or] [extruded cellular thermoplastic polycarbonate] panels conforming to
the specified requirements and other appropriate lab test specified
criteria, weighing not less than 2.4 kg per square meter 8 ounces per
square foot. The Contractor shall submit Test Reports as specified in the
Submittals paragraph. Size and color of skylight panels shall be as
indicated.
2.2
GLASS-FIBER PANELS
Glass-fiber reinforced polyester panels shall conform to ASTM D 3841, Class
[_____] and to the requirements of AAMA 1600.
2.2.1
Weatherability
The exposed faces of fiberglass sandwich type panels shall have a permanent
glass veil erosion barrier embedded integrally to provide maximum long term
resistance to reinforcing fiber exposure. The exterior face sheet shall be
uniform in strength and be resistant to penetration by pencil point.
2.2.2
Non Combustible Grid Core
The aluminum I-beams shall be 6063-T6 with provisions for mechanical
interlocking of muntin-mullion and perimeter to prevent high and low
intersections which do not allow full bonding surface to contact with face
material. Width of I-beam shall be no less than 11 mm 7/16 inch. I-beam
grid shall be machined to tolerances of not greater than plus or minus 0.05
mm 0.002 inch for flat panels. Panels shall withstand 650 degrees C 1200
degrees F fire for a minimum of one hour without collapse or exterior
flaming.
2.2.3
Adhesive
The laminate adhesive shall be heat and pressure resin-type engineered for
structural sandwich panel use. Adhesive shall pass testing requirements
