Green Shield uses rice hulls that are rich in lignin to help protect your deck against many common risks. Our rice hull composite deck boards have been specifically chosen to provide better protection against pests, fungi, moisture, and UV radiation than wood based deck boards.
Lignin
Lignin is the second most abundant natural biopolymer on Earth after cellulose. A natural binder in the cell walls, lignin not only protects plants from moisture but is also known to protect against pests, fungi, and UV radiation.
The Green Shield Difference
"Rice hull lignin is a powerful natural protection that comes in every Green Shield deck board. Experience the difference rice hull can make for your deck at a Deck Designer appointment."
