seal for a period of one (1) year from date of substantial
completion.
A. Acceptable Skylight Manufacturers
1. Sun-Dome Tubular Skylights
8352 Garden Road West Palm Beach, FL 33404 (561) 840-0095,
Toll-Free (800) 596-8414, Fax (561) 840-7606 SBCCI (Approval
#9928) and Miami-Dade Product Approval No. 01-1011.02 FBC 9B
72-PDM1684
2. Architect Approved Equal
a. Products of other manufacturers must be pre-qualified to
bid not less than 10 days prior to bid date.
b. Submit written proof of compliance with SBCCI and
Miami-Dade Certification
criteria for large missile impact test including supporting
technical data, engineering calculation, certification of
equivalent experience and samples for comparison.
3. Roof Dome
a. Polycarbonate CC-1 approved for Dade County test protocol.
Material is
co-extruded UV barrier to block harmful rays. Co-extrusion
eliminates chance of delamination. Thickness shall not be less
than 0.125”. Visible light transmittance shall be 92% or more.
4. Aluminum Flashing
a. Aluminum sheet stock shall be 3105 ASTM-B209 alloy and
temper and not less than nominal 0.040 wall thickness. Four
(4) flashings are available to fit roof slope from flat to
8:12 and custom flashings available for metal roof
application. Flashings are easily installed on shingle, flat
tile, barrel tile, cedar shake, tar & gravel, EPDM and Hypolon.
5. Reflective tubing.
a. Tubing is fabricated of .020 aluminum with a heat applied
silver laminate to
transfer light from the solar collector (dome) on the roof
through the tubes into the domed diffuser in the room in both
commercial and residential applications. Tests have shown that
there is minimal heat gain or loss with this type of system
which makes the unit very energy efficient and also replaces
the need for electric lighting during daytime hours.
6. Diffuser.
a. The domed diffuser is fabricated of acrylic CC-2 matieral
and is of white
translucent color for greater light distribution. Nominal
thickness of material is 0.125”. Color rendering index (CRI)
is almost 100% with this type system.
7. Sealants.
a. A sealant that is compatible with all substrates and field
applied in
accordance with manufacturer’s recommendations.
b. Flashing base seal should be OSI-Tripolymer “Quad”. Formula
remains flexible in heat or cold.
A. Skylights shall be factory fabricated and in kit form at
the manufacturer’s factory.
B. Assemble in the largest possible sections according to
job-site conditions and
application.
A. After verification of field conditions and properly
prepared openings, install tubular skylight system in strict
accordance with approved submittal drawing.
B. Skylight system must be installed by a factory authorized
and licensed contractor.
C. Apply appropriate sealants where indicated on shop drawings
and in accordance with manufacturer’s recommendations.
A. Clean all dome surfaces with soft cloth or sponge using
mild detergent.
