Current through Register 1531, September 27, 2024
Fiber reinforced polymer or fiberglass reinforced polymer
shall be permitted to be installed on the exterior walls of
buildings of any type of construction when such polymers meet the requirements
of Section 2603.5 and is fireblocked in accordance with Section 717. The fiber
reinforced polymer or the fiberglass reinforced polymer shall be designed for
uniform live loads as required in Table 1607.1 as well as for snow loads, wind
loads and earthquake loads as specified in Sections 1608, 1609 and 1613,
respectively.
Exceptions:
1. When all of the following conditions are
met:
1.1. When the area of the fiber
reinforced polymer or the fiberglass reinforced polymer does not exceed 20
percent of the respective wall area, the fiber reinforced polymer or the
fiberglass reinforced polymer shall have a flame spread index of 25 or less or
when the area of the fiber reinforced polymer or the fiberglass reinforced
polymer does not exceed 10 percent of the respective wall area, the fiber
reinforced polymer or the fiberglass reinforced polymer shall have a flame
spread index of 75 or less. The flame spread index requirement shall not be
required for coatings or paints having a thickness of less than 0.036 inch (0.9
mm) that are applied directly to the surface of the fiber reinforced polymer or
the fiberglass reinforced polymer.
1.2. Fireblocking complying with Section
717.2.6 shall be installed.
1.3.
The fiber reinforced polymer or the fiberglass reinforced polymer shall be
installed directly to a noncombustible substrate or be separated from the
exterior wall by one of the following materials:
corrosion-resistant steel having a minimum base metal thickness of 0.016 inch
(0.41 mm) at any point, aluminum having a minimum thickness of 0.019 inch (0.5
mm) or other approved noncombustible material.
1.4. The fiber reinforced polymer or the
fiberglass reinforced polymer shall be designed for uniform live loads as
required in Table 1607.1 as well as for snow loads, wind loads and earthquake
loads as specified in Sections 1608, 1609 and 1613, respectively.
2. When installed on buildings that
are 40 feet (12 190 mm) or less above grade, the fiber reinforced polymer or
the fiberglass reinforced polymer shall meet the requirements of Section 1406.2
and shall comply with all of the following conditions:
2.1. Where the fire separation distance is 5
feet (1524 mm) or less, the area of the fiber reinforced polymer or the
fiberglass reinforced polymer shall not exceed 10 percent of the wall area.
Where the fire separation distance is greater than 5 feet (1524 mm), there
shall be no limit on the area of the exterior wall coverage
using fiber reinforced polymer or the fiberglass reinforced polymer.
2.2. The fiber reinforced polymer or the
fiberglass reinforced polymer shall have a flame spread index of 200 or less.
The flame spread index requirement shall not be required for coatings or paints
having a thickness of less than 0.036 inch (0.9 mm) that are applied directly
to the surface of the fiber reinforced polymer or the fiberglass reinforced
polymer.
2.3. Fireblocking
complying with Section 717.2.6 shall be installed.
2.4. The fiber reinforced polymer or the
fiberglass reinforced polymer shall be designed for uniform live loads as
required in Table 1607.1 as well as for snow loads, wind loads and earthquake
loads as specified in Sections 1608, 1609 and 1613,
respectively.
