Woodguard is an organic certified structural building material that outlasts conventional untreated lumber and replaces lumber treated with prohibited substances. It’s more cost effective than steel or concrete products and requires no maintenance. Even the most durable species of lumber deteriorate from insect and dry rot decay. Now you have an economical alternative with Woodguard made with a non-toxic, organic borate compound to protect against these threats. After treatment our lumber is then coated in a non-toxic, engineered, UV-stabilized polymer blend that gives Woodguard its superior strength, life span and durability.
