The summer rainstorm weather will also hit, and the doors and windows of the home will usher in a big test. Therefore, the tightness, water resistance and firmness of broken bridge aluminum doors and windows have become the most concerned points. Therefore, when we buy and install doors and windows, we must add a thought.

In the process of buying doors and windows, not only consider the style, design, price, but more importantly, consider the practical performance. Strong winds and heavy rain have a greater impact on the doors and Windows of the home system, and it is an effective way to fight against heavy rain weather to have strong, sealed broken bridge aluminum doors and Windows.

The air tightness of doors and Windows refers to the ability of doors and Windows to prevent the penetration of external air flow, and the image of doors and Windows with good air tightness uses double or even three layers of vacuum insulating glass, plus two rubber seals, both warm and windproof. In addition, there is a greater impact on the air tightness of doors and Windows, and the air tightness of the open window is better.

Compared with ordinary doors and Windows, aluminum alloy doors and Windows have good air tightness, water tightness and sound insulation performance. High strength, good stiffness, strong and durable. When the doors and Windows are closed normally, they are easy to be damaged in the face of strong wind pressure, and the wind resistance of the profiles has high requirements.

The accessories of doors and Windows determine the life of the whole window, which is not only closely related to the airtight, watertight and wind pressure resistance of doors and Windows, but also plays a very important role in safety and other performance.
