普通铝门窗在夏季在太阳的烘烤之下铝合金的表面会非常的烫手，而铝材正是金属物质，导热的性能好，那么这种热量的传播就会增加屋内的温度，这也就是为什么有些人会觉得开着空调但是室内温度依然高的原因。但是断桥铝门窗在通过巧妙的设计采用在型材中加入了隔热条，在室内与室外之间形成一道防护罩，能有效的阻挡室内外气温的热传递，也就是说在夏天室外的热量不能通过型材传导进室内，而在冬天也能保证屋内的热量不会外渗。
Ordinary aluminum doors and windows in summer under the sun's baking aluminum alloy surface will be very hot, and aluminum is precisely metal material, thermal conductivity is good, then this heat transmission will increase the temperature of the room, which is why some people feel that the air conditioning is on but the indoor temperature is still high. But the broken bridge aluminium doors and windows add heat insulation strips in profiles through ingenious design, and form a protective cover between indoor and outdoor, which can effectively block the heat transfer of indoor and outdoor temperature. That is to say, in summer, outdoor heat can not be transmitted into the indoor through profiles, and in winter, it can also ensure that the heat inside the house will not be transferred. Extravasation
