Perennial Wood is real wood made to endure. It resists shrinking and swelling that causes bowing, cupping, and warping, without sacrificing the natural beauty of real wood.
What makes Perennial Wood so special is that it’s been modified throughout with proprietary TruLast Technology. Once modified, Perennial Wood is three times more resistant to harmful shrinking and swelling. This helps it last for decades.URL: http://www.perennialwood.com
