断桥隔热窗
Broken bridge insulation window
一般指的是铝型材，这属于节能的范畴。铝型材属于金属材料，建筑工程的墙体一般都采用了保温处理，由于室内外的温差与湿度的影响，往往在冬季与夏季温差大的时候容易在窗及圈梁等部位产生结露或冷凝等现象，造成节能损耗。这时对于这些部位有专门的处理方法，断桥窗由此而来，因为窗体玻璃可以为两层，中间有空气层能很好的起到节能作用，而与墙直接接触的窗体型材就成薄弱部位了。塑型窗还好点，如果是铝型材则导热性能高就得做断桥处理了。
Generally speaking, it refers to aluminum profile, which belongs to the category of energy saving. Aluminum profiles belong to metal materials, and the walls of construction projects generally adopt heat preservation treatment. Due to the influence of indoor and outdoor temperature difference and humidity, it is easy to produce condensation or condensation in windows, ring beams and other parts when the temperature difference is large in winter and summer, resulting in energy-saving loss. At this time, there is a special treatment method for these parts, and the broken bridge window comes from this, because the window glass can be two layers, and the air layer in the middle can play a good role in energy saving, and the window profile in direct contact with the wall becomes a weak part. Plastic windows are better. If they are made of aluminum, they have to be broken if they have high thermal conductivity.
