European most advanced countries for natural energy development and building the action of economy energy develop more early. Europe winter the temperature is lower, so in constructing shell to reduce indoor of heat getting of designing, opposite then be subjected to a value more in the home, and aluminum roller blinds is it applies in open the window department of the skill, for they and speech, window outdoor of the aluminum a window is everywhere it is thus clear that, have already been development mature of equipment. But if application in Taiwan, the Taiwanese temperature, relative humidity and day shoot hot etc.
