ELFI products are state-of-the art in the green-building construction market. In combination, ELFI wall and roofing systems deliver annual energy savings of 40-60% over traditional construction materials/methods.

A builder can erect ELFI component-centric buildings in one-third the time compared with traditional construction methods, yielding large labor cost savings. Our components are lightweight and easy to work with.

Also a major benefit: because the two materials are steel and EPS, there is never a problem with termites, mold, mildew, or warping, and there are no ozone-depleting chemicals; and our load-bearing components can be used up to nine stories.
