Metal's greenness

This year's METALCON International, held Oct. 11-13 in Atlanta, offers an educational program schedule that includes the type of technical seminars you would expect. But in addition, much of the schedule is focused on the ever-popular topic: "green."

Now encompassing anything remotely environmentally friendly, the term "green" can be applied to virtually any roof system—and metal is no different. Metal is a versatile enough product that it can be made more energy-efficient and environmentally friendly fairly easily.

This month, two of our features focus on green applications of metal roof systems.

In "Evaluating metal roof assemblies," page 24, the authors discuss how to increase the thermal performances of metal roof systems. The article is based upon the authors' research and was presented at the 2011 International Roofing Symposium held in September.
