断桥铝门窗和塑钢门窗是目前市场上两大主流的建筑门窗,消费者在选购门窗的时候往往不知道选择哪种门窗比较好,今天为大家分析讲解下断桥铝门窗和塑钢门窗的各项性能帮助大家更好的选择门窗产品。
目前,市场上主要应用的节能门窗有两种,分别是:塑钢门窗、隔热断桥铝门窗。从现在的应用情况来看,塑钢门窗主要用在农村市场、一些低档住宅小区并且楼层不高的一些建筑中。而隔热断桥铝门窗是城市住宅、商务公寓楼、标志性建筑应用的首选,甚至一些县城和村镇市场也逐渐认可这种门窗,其实这两种门窗有一些共性的优点和一些各自的特点。
塑钢窗使用虽然广泛,但由于断桥铝窗的一些突出性能,在市场上,断桥铝门窗逐渐占有优势。这到底是什么优势呢?
1、抗风压强度
虽然塑钢窗内有钢衬支撑,但钢衬与钢衬之间没连接,因此在强度上没有断桥铝合金高,抗风压强度相对断桥铝合金较低。
2、水密性
由于塑钢窗的开启扇(内平开)与框不是同一平面,向室内凹陷,因此容易积水(不会进入室内),需要通过排水槽排水,冬季不会结露。而断桥铝的开启扇与框在同一平面,不易积水,而且玻璃与窗框之间都会有玻璃胶进行密封,但由于其金属特性,在冬季可能出现结露现象。
3、气密性能
塑钢窗的PVC型材是通过焊接连接的,在连接处没有缝隙;而断桥铝合金窗是通过螺栓连接的,因此塑钢窗的气密性要优于断桥铝合金窗。
4、采光性能
由于塑钢窗的在外立面的投影尺寸比断桥铝合金窗大一些,其框扇构件遮光面积比断桥铝合金窗大10%左右,因此同样的洞口尺寸,塑钢窗的采光性能比断桥铝合金窗差10%左右。
5、隔声性能
由于断桥铝门窗采用的是双层铝合金门窗,中间采用隔热条,12A的中空玻璃,其隔音隔声性能远高于塑钢窗,其中就包括声能和热能,因此断桥铝门窗的隔声性要明显优于塑钢窗。
6、防火性能
塑钢窗的防火性能是难燃性,断桥铝合金窗是不烧性,因此断桥铝合金的防火性能要优于塑钢窗。
目前,建筑门窗大部分还是塑钢门窗为主,因为其价格相对于断桥铝门窗来说,便宜一倍,但是随着人们生活水平的提高,观念,开发商营销的改变,使得断桥铝门窗在很多家庭和楼盘中得到了很好的应用。
