为什么我们要选择铝合金门窗而不是塑钢门窗？
Why should we choose aluminum alloy doors and windows instead of plastic steel doors and windows?
铝合金窗相比塑钢窗来说，耐久性，稳定性，坚固程度更好。特别是封阳台，阳光房都是大面积的，在整体抗变形程度上铝合金的优势是普通塑钢没法比的（我们常见的办公楼，酒店大面积的幕墙都是铝合金材料的）。塑钢的优点就是本身型材的传热系数比较低，保温性能很好，所以在北方使用的比较多。近些年，铝合金门窗的断桥隔热技术已经很成熟了，保温隔热性能也非常好了，所以现在主流市场是铝合金为主导的。塑钢主要还是占领了相对便宜的低端市场。（某些高端塑钢除外）
Compared with plastic steel window, aluminum alloy window has better durability, stability and firmness. In particular, the balcony and sunshine room are large in area, and the aluminum alloy has an incomparable advantage over ordinary plastic steel in terms of overall deformation resistance (aluminum alloy is used for large area curtain walls of our common office buildings and hotels). The advantage of plastic steel is that its profile has low heat transfer coefficient and good thermal insulation performance, so it is used more in the north. In recent years, the bridge cutoff thermal insulation technology of aluminum alloy doors and windows has been very mature, and the thermal insulation performance is also very good. Therefore, the mainstream market is dominated by aluminum alloy. Plastic steel mainly occupied the relatively cheap low-end market. (except for some high-end plastic steel)
