This app will allow you to look up the commodity, application and exposure environment for treated wood products and find out the required retention by the AWPA and the CheckMark third party inspection details on the end tag. In addition the app allows you to look up the Treated Wood Councils (TWC) life cycle assessments (LCA) comparing treated wood versus substitutes as published by different peer reviewed journals. The app also provides information on different WWPI programs, EPA approved preservatives, fire-retardants, handling and answers frequently asked questions (FAQ). The app also includes location services for treated lumber yards. In effect this app will allow an architect or engineer to look up and specify the proper AWPA Use Category for a designed application knowing the exposure and location of the treated wood. The contractor will be able to look up the Use Category and get quotes from the lumberyard on specific preservatives that meet the proper retention. The building official and code inspector will be able to verify the end tags on the treated lumber or plywood meet the proper standards and show it to the contractor. This will help the entire building process to streamline one of the more confusing operations and improve the knowledge about and use of preserved wood products.
