任何门窗都有一定的使用寿命，随着时间流逝都会有不同程度的老化。耐老化、使用寿命长是断桥铝门窗的一个特点。根据对断桥铝门窗框耐候性、保温性、隔音性检测结果证明，硬质 PVC的老化过程是一个十分缓慢的过程，断桥铝门窗的使用寿命可达50年左右。
Any door and window has a certain service life, as time passes, there will be varying degrees of aging. Aging resistance, long service life, is a feature of the broken aluminum doors and windows. According to the test results of the weather resistance, heat preservation and sound insulation of the aluminum doors and windows of the broken bridge, the aging process of the hard PVC is a very slow process, and the service life of the broken bridge aluminum doors and windows can reach 50 years or so.
断桥铝门窗采用特殊配方的材料，其材料本身吸水率小于0.1%，框扇之间均用双层密封形式，缝隙处均装有优良的密封胶条，并于框材适当位置开设排水孔，角部也是通过机械焊接成型，所以断桥铝门窗的密封性能极好，不渗水且防潮、隔音，在保温性方面，门窗的框材材质与玻璃是影响热传导性的重要因素，断桥铝门窗的材质，其热传导系数仅为铝的 l/1250倍。
The aluminum doors and windows using a special formula of material, the material itself is bibulous rate is less than 0.1%, box fan are double sealing form, gaps are equipped with excellent sealing strip, and open drainage holes in the frame material position angle is through mechanical welding, so the broken bridge aluminum doors and windows of the excellent sealing performance, no water seepage and moistureproof, sound insulation, thermal insulation in terms of frame material of glass doors and windows is an important factor affecting the thermal conductivity of the aluminum doors and windows material, its thermal conductivity is only l/1250 times of aluminum.
对门窗而言， PVC单玻门窗与铝单玻门窗的传热性能之比为1：2，因此相同面积条件的断桥铝门窗其隔热性能较金属门窗为优，可节省能源消耗30%以上。在隔音性能方面，断桥铝门窗离马路6米的隔音效果和断桥铝门窗离马路18米的隔音效果相当。
For doors and windows, the heat transfer performance ratio of PVC single glass doors and windows is 1:2, so the thermal insulation performance of the broken aluminum doors and windows of the same area is better than that of the metal doors and windows, and the energy consumption can be saved by more than 30%. In the sound insulation performance, the broken bridge aluminum doors and windows away from the road 6 meters of sound insulation effect and the broken bridge aluminum doors and windows 18 meters away from the road sound insulation effect is quite.
相信很多业主都会碰到一个问题，那就是家里的门窗用久了，导致门窗老化，门窗合页出现断裂的现象，导致门窗关不紧。遇到这一类问题，相信业主都很矛盾，是选择换门呢?还是整个门框一起换掉?出现这一类的问题，我认为各位业主首先要做的，就是要明白断桥铝门窗变形的原因，也就是门窗用了几年之后关不紧的原因。
I believe many owners will encounter a problem, that is, the doors and windows used for a long time, leading to aging doors and windows, doors and windows hinge broken phenomenon, resulting in door and window closed tight. Encounter this kind of problem, believe that the owners are very contradictory, is the choice for the door? Or the entire frame change? This type of problem, I think the owners want to do first, the reason is to understand the deformation of the aluminum doors and windows, doors and windows is used because a few years later shut tight.
其次很多商家使用劣质的断桥铝门窗型材，这些材料比较薄，更加容易变形和下垂，使用年限更加的短。门窗配件也是很重要的，我认为使用优质的门窗配件比选择优质的断桥铝门窗型材更为重要，建议顾客尽量使用进口的五金件。
Secondly, many businesses use inferior broken aluminum doors and windows profiles, these materials are relatively thin, more easily deformed and sagging, the use of a shorter period of life. Door and window fittings are also very important. I think it is more important to use high quality door and window fittings than to choose high quality broken aluminum aluminum door and window profiles. It is suggested that customers use the imported hardware as much as possible.
