Substrates that have been treated using the present method include a borate-silicate polymer within the substrate. When the present substrates are wood, wood products, or green lumber, they may be used to build structures.Type: GrantFiled: October 28, 2002Date of Patent: November 23, 2004Assignee: Wood treatment Products, Inc.Inventors: Robert N. Grantham, Robert R. Weaver, III
