Waterproofing knowledge of aluminum alloy doors and Windows with broken bridge technology

Waterproof design principle

The waterproof performance of aluminum alloy doors and Windows with broken bridge mainly depends on their unique design and materials. Its waterproof system usually adopts the principle of pressure balance to ensure that rainwater can be effectively drained, avoiding water accumulation and leakage. Specifically, the design includes:

Drainage system: The sealing strip between the window frame and the window sash and the junction with the glass can effectively guide rainwater to flow away along the outer wall of the profile. The outer cavity of the profile is equipped with drainage holes to ensure that a small amount of water that seeps in can be smoothly discharged into the water collection trough.

Sealing structure: The aluminum alloy doors and Windows with thermal break usually adopt a three-seal structure, which rationally separates the water vapor cavity and significantly improves the water tightness and air tightness. This design not only prevents the infiltration of water, but also effectively isolates external noise and heat.

Installation and maintenance

When installing aluminum alloy doors and Windows with thermal break, waterproof treatment is of vital importance. The following are some key steps:

1. Application of sealant: At the junction of the window frame and the wall, waterproof sealant should be used to prevent rainwater from seeping into the room through the gaps. Make sure to clean the dust at the joints thoroughly before applying the glue to improve the sealing effect.

2. Drainage hole setting: Drainage holes must be provided at the lower end of the window and the sliding groove of the sliding window to ensure that accumulated water can be drained in a timely manner. The setting of drainage holes should follow a certain spacing to avoid blockage.

3. Regular inspection and maintenance: Regularly check the sealing strips and silicone sealant of the window frames to ensure there is no peeling or aging. If any problem is found, it should be replaced in time to maintain good waterproof performance.

Common Problems and Solutions

Water seepage problem: If water seepage is found in the window, first check whether the seal between the window frame and the wall is intact. If necessary, reapply glue. In addition, ensure that the drainage holes are unobstructed to prevent leakage caused by water accumulation.

Water accumulation phenomenon: When designing, ensure that the window sill has an appropriate slope to prevent water from flowing into the room. The design at the bottom of the window frame should be inclined outward to guide the water flow outward.

Through the above measures, the aluminum alloy doors and Windows with thermal break can effectively prevent moisture from seeping in, maintaining a dry and comfortable indoor environment.
