Wood is our only renewable natural resource and provides thousands of products to improve our lives. Wood's advantages to the construction industry are many. It can be worked and fabricated on the job; it is strong; has a great insulation value and can be finished in a variety of ways; it has warmth and an eye-appealing tone. It has limitless possibilities for creative design inspirations, and is the most economical building material from the standpoint of both material and labor. Wood creates a congenial atmosphere in which to live and work. It is only natural that we preserve all these excellent characteristics for as long as possible, and above all, preserve wood to make it last as long, if not longer, than other building materials.
