隔热断桥铝合金门窗的突出优点是强度高、保温隔热性好，刚性好、防火性好，采光面积大，耐大气腐蚀性好，综合性能高，使用寿命长，装饰效果好，使用高档的断桥隔型材铝合金门窗，是高档建筑用窗的首选产品。
The outstanding advantages of aluminium alloy doors and windows with heat insulation are high strength, good thermal insulation, good rigidity, good fire protection, large lighting area, good atmospheric corrosion resistance, high comprehensive performance, long service life, good decoration effect. Aluminum alloy doors and windows with high-grade bridge insulation profiles are the preferred products for high-grade building windows.
看用料:优质的铝合金门窗所用的铝型材，厚度、强度和氧化膜等，应符合国家的有关标准规定，窗非弹性装配结构壁厚在1.4毫米以上，门非弹性装配结构壁厚在2.0毫米以上。抗拉强度达到每平方米毫米157牛顿，屈服强度要达到每平方毫米108牛顿，氧化膜厚度应达到10微米。如果达不到以上标准，就是劣质铝合金门窗，不可使用。
Seeing materials: Aluminum profiles, thickness, strength and oxide film used in high-quality aluminium alloy doors and windows should meet the relevant national standards. The wall thickness of window inelastic assembly structure is more than 1.4 mm, and that of door inelastic assembly structure is more than 2.0 mm. Tensile strength is 157 Newtons per square meter, yield strength is 108 Newtons per square millimeter and oxide film thickness is 10 microns. If it fails to meet the above standards, it is inferior aluminium alloy doors and windows that can not be used.
看加工:优质的铝合金门窗，加工精细，安装讲究，密封性能好，开关自如。劣质的铝合金门窗，盲目选用铝型材系列和规格，加工粗制滥造，以锯切割代替铣加工，不按要求进行安装，密封性能差，开关不自如，不仅漏风漏雨和出现玻璃炸裂现象，而且遇到强风和外力，容易将推拉部分或玻璃刮落或碰落，毁物伤人。
Look at the processing: high-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, easy switching. Poor quality aluminium alloy doors and windows, blindly select series and specifications of aluminium profiles, rough manufacturing, sawing instead of milling, do not meet the requirements of installation, poor sealing performance, unsound switches, not only leakage of wind and rain and glass cracking, but also encounter strong wind and external forces, easy to push and pull parts or glass blow down or Collision, destruction and injury.
