Expandable Polystyrene (EPS) is an excellent insulator as it bars heat from entering structures, helping to reduce overall building temperature. Partnering with the multinational manufacturer, STO Corporation, which specializes in exterior insulation, Free Form Factory offers an economical and low maintenance method for insulating commercial spaces and private residences. With the External Insulating Finishing System (EIFS), EPS panels are affixed to the surface of outer walls using a special glue. A textured concrete coating is then applied to the EPS and the paint or trowel-on is added in the final stage.
