Deconstruction was a television series that appeared on the Do-It-Yourself network.  It was a show that was dedicated to exploring the science behind home improvement.  In 2009, the producer for Deconstruction asked WWPI for help to develop a show that would demonstrate the science behind pressure treated wood.  The segment opens at one of WWPI’s treater members – Allweather Wood plant in Colorado – to describe the wood treating process. At 9 minutes and 30 seconds they show the durability and termite test results.   They also do a later segment on fire retardants starting at 16 minutes and 30 seconds. This is a great educational and fun video to watch.  We hope you enjoy it and share it with others.


Webinar Details!

Our next webinar is being held on Thursday May 30, 2013 from 2:30 to 4:00 pm EST.

The topic this time is Pole Top Assemblies: Pole top assemblies are used to support conductors on wooden poles. This webinar will discuss the different types of assemblies (tangent, angle, and deadend) along with the framing options. Each component of the assemblies will be discussed in terms of its strength and proper application based on the conductor size. The focus will be on wooden crossarms with discussions on fiberglass arms. Calculations will be shown for maximum line angles within load limits of the pin and insulators. Strength of dead crossarms will include methods for selection of crossarms based on conductor tension.
