断桥铝窗户保温隔热性好。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。
Broken bridge aluminium windows have good thermal insulation. It adopts the soft combination of the inner and outer frames of heat insulation profiles and the three sealing forms of one rubber strip and two wool strips to close tightly, with excellent air-tightness and water-tightness and excellent heat preservation performance. The window fan adopts hollow glass structure, which makes the windows truly show sound insulation, heat insulation, heat preservation and excellent function, and saves a lot of mining and cooling costs. The value of heat transfer coefficient K is less than 2.23-2.94w/2K. The energy-saving effect is remarkable. The energy-saving cost in several years is enough to make up for the previous investment
