断桥铝窗是现代建筑中广泛应用的一种高性能门窗类型，以下是对其的详细介绍：

Broken bridge aluminum window is a high-performance door and window type widely used in modern architecture. The following is a detailed introduction to it:

基本概念

Basic concepts

断桥铝窗是由断桥铝合金材料制成的窗户。所谓“断桥”，是指在铝合金型材中间加入隔热条，将内外铝材分开，形成断热桥，从而有效阻止热传导。这种设计使得断桥铝窗具有优越的保温隔热性能、良好的隔音效果以及耐用性。

Broken bridge aluminum window is a window made of broken bridge aluminum alloy material. The so-called "broken bridge" refers to adding insulation strips in the middle of aluminum alloy profiles to separate the inner and outer aluminum materials, forming a thermal break bridge, effectively preventing heat conduction. This design enables the broken bridge aluminum window to have superior thermal insulation performance, good sound insulation effect, and durability.

主要结构

Main structure

断桥铝窗的基本结构包括铝合金型材、隔热条、玻璃、密封条及五金配件等部分。其中，铝合金型材是窗户的主要承重和支撑部分；隔热条则起到保温隔热的作用；玻璃通常采用中空玻璃，以提高窗户的隔音和保温性能；密封条用于增强窗户的密封性能；五金配件则包括执手、铰链等部分，用于窗户的开启和关闭。

The basic structure of a broken bridge aluminum window includes aluminum alloy profiles, insulation strips, glass, sealing strips, and hardware accessories. Among them, aluminum alloy profiles are the main load-bearing and supporting parts of windows; The insulation strip plays a role in thermal insulation; Hollow glass is usually used to improve the sound insulation and thermal insulation performance of windows; Sealing strips are used to enhance the sealing performance of windows; Hardware accessories include handles, hinges, and other parts used for opening and closing windows.

材质与特点

Material and Characteristics

铝合金型材：断桥铝窗的铝合金型材通常选用优良原生铝，具有强度高、耐腐蚀性好等特点。型材的厚度也是影响窗户性能的重要因素之一，一般优良的断桥铝型材厚度应在1.4mm以上。

Aluminum alloy profiles: The aluminum alloy profiles for bridge cut aluminum windows are usually made of high-quality primary aluminum, which has the characteristics of high strength and good corrosion resistance. The thickness of the profile is also one of the important factors affecting the performance of the window. Generally, the thickness of excellent broken bridge aluminum profiles should be above 1.4mm.

隔热条：优良的隔热条采用PA66尼龙材质，这种材料不仅隔热效果好，还耐高温、抗老化。而劣质隔热条往往使用PVC材料，隔热效果差且容易老化。

Heat insulation strip: excellent heat insulation strip is made of PA66 nylon, which not only has good heat insulation effect, but also is resistant to high temperature and aging. Poor quality insulation strips often use PVC material, which has poor insulation effect and is prone to aging.

玻璃：中空玻璃是断桥铝窗的标配，优良的中空玻璃可以有效提升窗户的隔音和保温性能。购买时，建议选择厚度在5mm以上的钢化玻璃，并确保中空部分填充有惰性气体（如氩气），以提升保温效果。此外，还可选择夹胶玻璃或真空玻璃，以进一步提高窗户的隔音效果。

Glass: Hollow glass is a standard configuration for bridge cut aluminum windows, and excellent hollow glass can effectively improve the sound insulation and thermal insulation performance of windows. When purchasing, it is recommended to choose tempered glass with a thickness of 5mm or more and ensure that the hollow part is filled with inert gas (such as argon) to enhance the insulation effect. In addition, laminated glass or vacuum glass can also be chosen to further improve the sound insulation effect of the window.

五金配件：五金配件的质量决定了断桥铝窗的使用寿命和安全性。优良的五金配件通常采用不锈钢、铜质或知名品牌的产品，具有耐用、耐腐蚀、密封性能好等特点。

Hardware accessories: The quality of hardware accessories determines the service life and safety of bridge aluminum windows. Excellent hardware accessories are usually made of stainless steel, copper, or well-known brand products, which have characteristics such as durability, corrosion resistance, and good sealing performance.

密封条：好的密封条决定了窗户的密封性能和防水性。硅胶密封条是目前很好的选择，柔韧性好且耐老化。也可选择采用三元乙丙材质+发泡处理的密封条，这种密封条耐热、耐低温、不易老化，且具有良好的弹性，能够保障更好的密封效果。

Sealing strip: A good sealing strip determines the sealing performance and waterproofing of the window. Silicone sealing strips are currently a good choice, with good flexibility and aging resistance. Alternatively, a sealing strip made of EPDM material and treated with foam can be chosen. This sealing strip is heat-resistant, low-temperature resistant, not prone to aging, and has good elasticity, ensuring better sealing performance.
