“断桥铝”这个名字中的“桥”是指材料学意义上的“冷热桥”，而“断”字表示动作，也就是“把冷热桥打断”。
"Bridge" in the name "broken bridge aluminum" refers to the materials science in the sense of "cold bridge", and "break" the word says action, namely "the hot and cold bridge interrupted".
具体地说，因为铝合金是金属，导热比较快，所以当室内外温度相差很多时，铝合金就可以成为传递热量的一座“桥”，这样的材料做成门窗，它的隔热性能就不佳了。

Specifically, because of the aluminum alloy is a metal, heat faster, so when the indoor and outdoor temperature varies a lot, aluminium alloy can transfer heat to become a "bridge", such materials doors and Windows, its heat insulation performance is poor.
而断桥铝是将铝合金从中间断开的，它采用硬塑将断开的铝合金连为一体，我们知道塑料导热明显要比金属慢，这样热量就不容易通过整个材料了，材料的隔热性能也就变好了，这就是“断桥铝（合金）”的名字由来。
And broken bridge aluminum aluminum alloy has cracked, it USES a hard plastic will disconnect the aluminum alloy is an organic whole repeatedly, we know that the plastic thermal conductivity significantly slower than metal, so heat is not easily through the material, material of insulation performance is better, this is "broken bridge aluminum (alloy)" cause of name.
断桥铝又叫隔热断桥铝型材，隔热铝合金型材，断桥铝合金，断冷桥型材，断桥式铝塑复型材，它比普通的铝合金型材有着优异的性能。
Broken bridge aluminum is also called heat insulation broken bridge aluminum, heat insulation aluminum alloy profiles, broken bridge aluminum alloy, cold bridge profile, broken bridge type aluminum-plastic compound material, it has more excellent performance than ordinary aluminum profile.
