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.
