Get smart on Treated Wood with the WWPI app!

WWPI App

WWPI has released a free interactive smartphone app for treated wood specifiers, suppliers, users and inspectors. This new 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 Council's life cycle assessments (LCA) comparing treated wood vs. substitutes as published by different peer reviewed journals. The app also provides information on different WWPI programs, EPA approved preservatives, fire retardants and safe handling and answers frequently asked questions (FAQ).  The app will soon include a search services for treated lumber yards near your location.

The app will allow an architect or engineer to search, review and specify the proper AWPA Use Category for a designed application. Contractors will be able to look up the Use Category and get quotes from the lumberyard on specific preservatives that meet the proper retention. Building officials and code inspectors can verify the end tags on treated lumber or plywood to ensure they meet the proper standards.

Utilizing the app will help the entire building process by streamlining one of the more confusing operations and improve the knowledge about and use of preserved wood products.

The app is available on all tablet and smartphone operating systems, through the iTunes Store for iPhones and iPads and the Google Play Store for Android phones and tablets. Also avaiable is an HTML5 version for Microsoft and Blackberry users. Scan the QR code below to download it.
