As we all know, although there are steel linings inside the plastic steel window, the steel linings are not connected, which reduces the wind pressure intensity, so the broken bridge aluminum alloy window is better in terms of wind pressure intensity.

Second: water tightness

Watertightness is the key to determine whether the window will leak, because once it leaks, it will lead to indoor water accumulation. Plastic steel window is not watertight, and its structure determines that it sinks indoors, which is easy to cause water accumulation. On the contrary, there is no such worry about broken bridge aluminum alloy windows.

Third: air tightness

What I am most afraid of is the air leakage from the windows in winter, which makes the room chilly. As long as plastic-steel windows are installed, this problem does not exist. After all, it is welded, leaving no gaps. Although the broken bridge aluminum alloy window is easy to install, the bolt connection mode is easy to leak air.
