This study was conducted to establish the direction of developing windows and forecast effectively the adequate insulation performance level through the performance identification of each component of a window. Based on the insulation performance of windows tested for the high-efficiency appliance certification program, this study presented the pattern of insulation performance change according to the component change after comparatively analyzing each window’s general performance value as acquired according to the materials, opening and closing types, and glass composition change. For the window frame materials, plastic was 58%, and aluminum, 34%. For the opening and closing types by frame material, the curtain wall type was approximately 32% in the case of the aluminum window the 2-track sliding type was 46% in the case of plastic window, thereby taking up the largest share in terms of material. In terms of the criterion as the mean value of insulation performance of the selected and tested windows, aluminum windows met the criterion when Low-e glass was applied. Plastic windows also met the criterion when the thickness of the gas-filling layer was increased to 12mm. |
