RASTRA produces a high quality building system from recycled foam plastics. We pioneered the insulated concrete form (ICF) industry and invented and developed the Compound or Composite ICF (ICCF). RASTRA is the solution for this century to build environmentally conscious, energy-efficient buildings that provide a safe and healthy living environment.
This specification includes RASTRA Insulated Concrete forms for concrete that stays in place as permanent building insulation for energy-efficient, cast-in-place, reinforced concrete walls, floors, and roofs.
