2.0 USES
The Mesh Guard System described in this report is limited to
interior and exterior use as an in-fill system on guards for
balconies, porches, and decks of Type V-B (IBC)
construction, and dwellings constructed in accordance with
the IRC.
3.0 DESCRIPTION
3.1 General:
The Mesh Guard System consists of guard in-fill
components installed on either wood framed or
preservative-treated wood framed guards.
3.2 In-fill System:
3.2.1 General: The Mesh Guard system is installed on
guards with a minimum height of 36 inches (914 mm) or
maximum height of 44 inches (1117.6 mm) above the
walking surface. The mesh screening consists of a vinyl
coated polyester core yarn-woven with a visible orange
striping along the top and bottom borders. The mesh
screening is held in place with an extruded polyvinyl
chloride (PVC) flat spline with a visible orange striping;
both are rolled into the cavity of the extruded PVC mesh
guard base with a screening tool. A galvanized 14 gauge
(1.63 mm) steel reinforcement track is used to secure the
PVC mesh guard base to the wood framing. A decorative
PVC mesh guard cap snaps over the PVC mesh guard
base and comes in white, beige, grey, and brown. The
PVC mesh guard base and cap come in 1-
1
/
2
inch (38.1
mm) widths. See Figure 1 for details of the Mesh Guard
System.
3.2.2 Durability: The Mesh Guard System has been
evaluated for structural performance when exposed to a
temperature range from -20°F (-29°C) to 125°F (52°C).
3.2.3 Surface-burning Characteristics: When tested in
accordance with ASTM E84, the mesh screening and PVC
components of the Mesh Guard System have a flame-
spread index of 25 or less and a smoke-developed index of
450 or less.
4.0 DESIGN AND INSTALLATION
4.1 Design:
The Mesh Guard System, when used as an in-fill system
on guards, is satisfactory to resist loads specified in
Section 1607.8.1.2 of the 2015 and 2012 IBC (Section
1607.7.1.2 of the 2009 IBC) and Table R301.5 of the IRC,
when installed at the maximum clear span distance of
72 inches (1828.8 mm) between the posts.
4.2 Installation:
Installation must be in accordance with the manufacturer’s
published installation instructions, this report, and guard
height and opening limitations provisions specified in
Section 1015 of the 2015 IBC (Section 1013 of the 2012
and 2009 IBC) and Section R312 of the IRC, as applicable.
The manufacturer’s published installation instructions must
be available at the jobsite at all times during installation.
When installed on wood species with the minimum
specific gravity of 0.42, each PVC mesh guard base is cut
to length and installed with the galvanized 14 gauge (1.63
mm) steel reinforcement track using #6 x 1-
1
/
4
inches (31.8
mm) stainless steel screws spaced at 8 inches (203.2 mm)
on center. On vertical installations of the PVC mesh guard
base, the galvanized 14 gauge (1.63 mm) steel
reinforcement track was drilled ¾ inch (19.1 mm) from the
top and bottom with an additional #6 x 1-
1
/
4
inch (31.8 mm)
stainless steel screw to secure the track to the PVC mesh
guard base. The mesh screening, cut to length along the
orange striping, is stretched across the mesh guard base
and installed by rolling the PVC flat spline with the orange
striping facing down, cut to length, into the cavity of the
PVC mesh guard base with a screening tool. After the PVC
flat spline is inserted, the decorative PVC mesh guard cap
