The Environamics demountable wall was selected as the building standard during the Pentagon Renovation program as the standardized product to be used throughout the Pentagon, including all Air Force rooms. Therefore, this product is currently widely in place. As Air Force missions change and reconfigurations to add personnel or replacements are needed, supplementing new purchases to match the existing walls promotes economy and efficiency to fully integrate, co-mingle and create a cohesive, professional appearance in all Headquarters Air Force Pentagon offices.
