断桥铝门窗保温隔热性好。采用隔热型材内外框软性结合，边框采用一胶条，双毛 条的三密封形式，关闭严密，气密、水密性能特佳、保温性能优越；窗扇采用中空玻璃 结构，使窗户真正显示出隔音、隔热、保温、功能卓越，大量节省采暧和制冷费用，传 热系数K值经检测2.23—2.94w/2K以下，节能效果显著 ，几年的节能费用足以弥补前期的投资。
The aluminum doors and windows of bridge cutoff have good thermal insulation. It adopts the combination of internal and external frames of thermal insulation profiles. The frame adopts the three sealing forms of one rubber strip and two wool strips. It is tightly closed, airtight and watertight, and has excellent thermal insulation performance. The window sash adopts the hollow glass structure, which makes the window truly show excellent sound insulation, heat insulation, thermal insulation and functions, and saves a lot of heating and cooling costs The value of thermal coefficient K is less than 2.23-2.94w/2k, so the effect of energy saving is remarkable. The cost of energy saving in several years is enough to make up for the investment in the early stage.
断桥铝门窗防水功能。利用压力平衡原理设计有结构排水系统，下滑设计斜面阶梯式，设排水口，排水畅 通，水密性好。
Waterproof function of aluminum doors and windows for bridge breaking. The structure drainage system is designed by using the principle of pressure balance, the sliding slope is designed as a ladder type, and the drainage outlet is set, the drainage is smooth, and the water tightness is good.
