One of the principal advantages of this type of house is it´s energy-saving characteristics. Exterior wall panels are pre manufactured in a controlled environment using Expanded Polystyrene (EPS) insulation panels sandwiched between I-beam studs instead of conventional wood frame and glass fiber batt construction. Our unique design produces a structurally superior home that stays warm in the winter, cool in the summer, and cuts energy costs by up to half. In that way there is nearly 50% of energy costs reduction in heating as well as in air-conditioning.
