保温隔热冬暖夏凉热反射窗帘是在一定的化纤布表面镀上厚度不足1μ的特种金属后制成,系中国建筑一局科研所新近推出的节能科研成果。此种窗帘冬天能保温,夏天可隔热,使房屋冬暖夏凉,能耗减少,且美观实用,价格便宜。人体和一切物体按其自身温度的不同,都向外发出不同波长的热射线。在常温下则发出长波红外 Insulation heat insulation curtains are made of special metal with a thickness of less than 1μ on a certain chemical fiber cloth surface, which is a research result recently launched by the Institute of Science and Technology of China Construction Bureau. Such curtains can keep warm in the winter and can be insulated in the summer, making the houses cool in winter and cool in summer, reducing energy consumption, being beautiful and practical, and being cheap. The body and all objects emit heat rays of different wavelengths, depending on their own temperature. It emits long-wave infrared light at room temperature
