Aluminum profile Definition:

Aluminum profiles are aluminum materials with different cross-sectional shapes obtained by hot-melting and extruding aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion and coloring. Among them, the coloring mainly includes: oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, wood grain transfer and other processes.

Aluminum alloy doors and windows

Definition：
1. Aluminum alloy door: a door with a frame and fan structure made of aluminum alloy building aluminum profiles.

2. Aluminum alloy windows: windows with frame and fan structures made of aluminum alloy construction aluminum profiles. Doors and windows are generally named as "model + function form", such as: 60 series inward opening and inverting windows. The name of the door and window series is generally named after the width of the aluminum profile frame, divided by function.

1). Sliding: including sliding windows, sliding doors, inward sliding doors, lifting sliding doors;

2). Casement: including casement inside, casement outside, inside-opening and inverted window, top-hung window, bottom-hung window

3). Folding doors and windows

3. Characteristics of aluminum alloy doors and windows

Energy-saving doors and windows
Many people don't pay attention to the doors, windows and glass of residential buildings when they buy a house, they just feel "beautiful" from the appearance. Industry insiders pointed out that doors, windows and glass are not only the eyes of buildings, but also the key structure of building energy saving.
The bigger the window, the less energy-saving
The largest area of window heat dissipation is glass, not window frames. Glass accounts for 70% to 90% of the area of different types of windows. Commonly used window types in buildings are generally sliding windows, casement windows and fixed windows
The structure of the stacking window determines that it is not an ideal energy-saving window. From a structural point of view, casement windows have obvious advantages over sliding windows. energy-saving aluminum profile, the latest art energy-saving aluminum profile.

The window frame of the fixed window is embedded in the wall, and the glass is directly installed on the window frame, and the four sides where the glass and the window frame are in contact are sealed with sealant. Under normal circumstances, with good water tightness and airtightness, it is difficult for air to form convection through the sealant, so convective heat loss is minimal.
