断桥铝性能：
Performance of bridge broken aluminum:
1、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。
1. The aluminum doors and windows with broken bridge have good thermal insulation. The inner and outer frame of heat insulation profile is combined with soft, and the frame is sealed with one rubber strip and two wool strips. It is closed tightly, with excellent air and water tightness performance and superior heat preservation performance; The window sash adopts insulating glass structure, which makes the window truly show excellent sound insulation, heat insulation, heat preservation and functions, and saves a lot of heating and cooling costs. The heat transfer coefficient K is less than 2.23-2.94w/2k, which shows remarkable energy-saving effect. The energy-saving cost in a few years is enough to make up for the early investment.
2、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。
2. Waterproof function of bridge broken aluminum doors and windows. Based on the principle of pressure balance, the structural drainage system is designed. The sliding slope is designed to be stepped, and the drainage outlet is set. The drainage is smooth and the water tightness is good.
3、断桥铝门窗防结露、结霜。断桥铝型材可实现门窗的三道密封结构，合理分离水汽腔，成功实现气水等 压平衡，显著提高门窗的水密性和气密性，达到窗净明亮的效果。
3. The aluminum doors and windows of the broken bridge shall be protected against condensation and frost. The broken bridge aluminum profile can realize the three seal structure of doors and windows, reasonably separate the water vapor cavity, successfully realize the equal pressure balance of air and water, significantly improve the water tightness and air tightness of doors and windows, and achieve the effect of clean and bright windows.
4、断桥铝门窗防蚊虫纱窗设计。隐形纱窗，可内外选择安装使用，具有防蚊虫，苍蝇，尤其适合北方多蚊虫地区。
4. Design of mosquito proof screen window for broken bridge aluminum doors and windows. Invisible screen window, can be installed inside and outside, with anti mosquito, fly, especially suitable for Northern mosquito areas.
