In terms of quality performance of aluminum wood doors and windows, the performance of air tightness, water tightness, sound insulation, heat preservation and energy saving mainly depends on the sealing performance, material and glass configuration of doors and windows.
In addition to sliding windows, it is not difficult to seal hanging windows on ordinary casement windows, and most brand doors and windows can meet national and European standards.
The rest mainly depends on the glass configuration. Ordinary household double-layer insulating glass is enough, and building curtain walls generally use three-glass and two-cavity glass.
Therefore, the choice of doors and windows mainly depends on structural modeling and price.
I renovated my home some time ago and chose it online for a long time. Finally, I found an Adiya door and window, which is also a high-grade aluminum door and window. Unlike the German door and window structure in the world, sash and window frame are not side by side, but outside the window frame, shielding each other. In this way, the general picture frame area is saved, the lighting area is larger, and the picture frame lines are slimmer and simpler. And the width of the open fan is the same as that of the fixed fan, which is very beautiful and not German. Moreover, their external translation sliding window also solves the problem of poor sealing caused by left and right sliding. When opening the window, the movable fan is pushed out first, then pushed and pulled left and right, without friction, and the left and right fans of the sliding window are also in the same plane, which is beautiful and elegant as a whole.
