断桥铝性能：
Performance of bridge cutoff 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 bridge cutoff aluminum doors and windows have good thermal insulation. The inner and outer frames of thermal insulation profiles are combined flexibly. The frame adopts a three sealing form of one rubber strip and two wool strips, which is tightly closed, with excellent air and water tightness and superior thermal insulation performance; The window sash adopts the hollow 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 value is tested to be below 2.23-2.94w/2K, and the energy saving effect is significant. The energy saving costs in a few years are enough to make up for the initial investment.
2、断桥铝门窗防水功能。纤维 驱鸟设备 保定通风管道 塑料土工格栅 检查井模具 流水槽模具 锻造厂家 华尔街铜牛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 cutoff aluminum doors and windows. The structural drainage system is designed based on the principle of pressure balance, and the sliding design is inclined and stepped, and the drainage outlet is set to ensure smooth drainage and good water tightness.
