For the purpose of documenting the wind-borne debris protection method for the exterior glazing (windows) of the
structure located at:
I (print name) attest to the following:
1) The structure is classified as an R-3 or R-4 occupancy with mean roof height of 33 ft. or less.
2) The building is within one mile of the mean coastal high water line.
3) I have applied for a Building Permit under an exception to the required “Protection of Openings” found in the
Florida Building Code. (R301.2.1.2 and 1609.1.2)
NOTICE: This is only an option for Groups R-3 and R-4 occupancies.
Exception: Wood structural panels with a thickness of not less than
7
/
16
inch (11 mm) and a span between
lines of fasteners of 44 inches (1118 mm) shall be permitted for opening protection in buildings with a mean
roof height of 33 feet or less in locations where V
ult
is 180 mph or less. Panels shall be precut to overlap the
wall such that they extend a minimum of 2 inches (50.8 mm) beyond the lines of fasteners and attached to
the framing surrounding the opening containing the product with the glazed opening. Panels shall be
predrilled as required for the attachment method and secured with corrosion-resistant attachment hardware
permanently installed on the building.
a. Attachments shall be designed to resist the component and cladding loads determined in accordance
with either Table R301.2(2) or ASCE 7, with the permanent corrosion-resistant attachment hardware
provided and anchors permanently installed on the building.
b. As an alternative, panels shall be fastened at 16 inches (406.4 mm) o.c. along the edges of the
opposing long sides of the panel.
I. For wood frame construction, fasteners shall be located on the wall such that they are embedded
into the wall framing members, nominally a minimum of 1 inch (25.4 mm) from the edge of the
opening and 2 inches (50.8 mm) inward from the panel edge. Permanently installed anchors used
for buildings with wood frame wall construction shall have the threaded portion that will be
embedded into the wall framing based on

to penetrate through the exterior wall covering with sufficient embedment length to provide an
allowable minimum 300 pounds ASD design withdrawal capacity. For concrete or masonry wall
construction, fasteners shall be located on the wall a minimum of 1.5 inches (37.9 mm) from the
edge of the opening and 2 inches (50.8 mm) inward of the panel edge. Permanently installed
anchors in concrete or masonry wall construction shall have an allowable minimum 300 pounds
ASD design withdrawal capacity.
II. For concrete or masonry wall construction, fasteners shall be located on the wall a minimum of 1.5
inches (37.9 mm) from the edge of the opening and 2 inches (50.8 mm) inward of the panel edge.
Permanently installed anchors in Concrete or masonry wall construction shall have an allowable
minimum 300 pounds ASD design withdrawal capacity and an allowable minimum 525 pounds
