Our Sustainability Philosophy

We live in a dynamic, creative, and exciting time to be in architectural design and construction. New building products and methods are revolutionizing the way we view shelter, energy, and ultimately, how we live together in our communities.

Innovative builders are demanding better energy efficiency, greater sustainability, and healthier building materials. We are not only aware of these trends, but we are a leading business in the building industry, providing reputable, long-known, long-enduring alternate building materials that meets the demand of this emerging market.

We are fully committed to this new paradigm and are enthused and proud to manufacture and offer the Faswall® insulated wood chip-cement green building system.
