King StarBoard® WG is a high-density polyethylene sheet with a wood grain finish. It is the
product of a proprietary process called K-Stran™, the most advanced manufacturing process
for superior flatness and consistency. King StarBoard® WG has a wood grain finish on
both sides of the sheet. It is environmentally stabilized to withstand the harshest outdoor
conditions. King StarBoard® WG will not rust, delaminate or rot when exposed to UV,
humidity or water. It is ideal for a variety of applications from replacing wood, to building
furniture. The wood grain polymer sheet never needs painting or refinishing, works like
wood, and is easy to fabricate with common woodworking tools and techniques.

King Plastic pioneered King StarBoard®, the original marine-grade polymer sheet. Now, we
deliver the highest performance and durability in our new wood grain plastic sheet King
StarBoard® WG with elegance and casual sophistication for outdoor living. King StarBoard®
WG, the all-weather wood grain polymer sheet inspiring everyone to live outdoors.

King StarBoard® WG is upgradable to King MicroShield® with an advanced antimicrobial
technology for protecting the product surface against stain and odor causing bacteria, algae
and fungi.*

King StarBoard® WG is upgradable with King FlameShield, for ASTM E-84 Class A Flame
Compliance and CAN/ULC-S102 for Canadian Compliance.

The ASTM E84

This test method is intended to compare the surface flame spread and smoke developed measurements to those obtained from the tests of mineral fiber cement board and select grade red oak flooring. The results are expressed as Flame Spread Index and Smoke Developed Index.

Class A Interior Finish:

Flame Spread Index 0-25, Smoke Developed Index 0-450. Includes any material classified at 25 or less on the flame spread test scale and 450 or less on the smoke developed test scale. Any element thereof when so tested shall not continue to propagate fire.
