Insulsteel Structural Building Systems
The EcoShell™ is designed and fabricated using composite steel and expanded polystyrene injection molded panels numbered and ready for onsite assembly. The EcoShell™ “kit of parts” when assembled “onsite” exceeds quality standards prescribed by USGBC LEED Platinum and state and local building codes for high winds, flooding, and seismic activity.
Insulsteel ExoSkeleton™: Recycled steel components (interior walls, floor system, and roof trusses) are manufactured offsite at the new Insulsteel LGS factory. The entire building is panelized eliminating more than 50% of labor hours and virtually all construction waste.
