In response to requests of the global low carbon emission energy-saving building materials and due to the rapid rise in oil prices, we developed the eco-friendly PVC combined with integrated high-performance stainless steel insulated windows frame. We have made a compound chassis for windows composed of stainless and eco-friendly PVC. This compound window chassis makes the most of strong points of both materials and shows excellent insulation, airtightness and wing proofing. Heat insulating performance of the developed stainless steel insulated windows is excellent and it meet the demands for energy saving improvements and housing culture to improve the quality of life. A new beautiful appearance development can improve the performance of highly effective thermal insulation building materials and will contribute to the development of industrial competitiveness and energy-saving building technology areas.
