The EPC are materials produced in the presence of physical / chemical blowing agents, resins, additives and modifiers resulting in a foaming material with closed cells to enhance and improve impact resistance, weathering characteristics and superior thermal performance. Additionally the EPC also provide a window with the appearance and beauty of wood, without the maintenance.
