3.1 General:
The deck boards described in this report are wood
thermoplastic composite lumber (WTCL) consisting of a
minimum of 50 percent wood flour and a maximum of
50 percent high-density polyethylene and other processing
additives. The deck boards are manufactured by an
extrusion process in accordance with the approved quality
assurance manual in four colors (redwood, cedar, gray and
walnut). Latitudes Capricorn, Latitudes Captiva, and Style
Selections have a 1/32-inch-thick (0.8 mm) polyethylene
coating embossed on top. The deck boards are either solid
or slotted.
The attributes of the deck boards have been verified as
conforming to the provisions of (i) CALGreen Section
A5.406.1.2 for reduced maintenance; (ii) ICC 700-2012
Sections 602.1.6 and 11.602.1.6 for termite-resistant
