[China Glass Network] Many people do not pay attention to the doors and windows of residential buildings when they buy a house. The glass just feels "beautiful" from the appearance. According to industry insiders, doors, windows and glass are not only the eyes of buildings, but also the key structure of building energy conservation.
The bigger the form, the less energy saving
The large area of ​​the form heat dissipation is glass, not the window frame. The glass accounts for 70% to 90% of the window area of ​​different types. The window type commonly used in buildings is generally a sliding window, a casement window and a fixed window.
The structure of the sliding window determines that it is not an ideal energy-saving window: structurally, the casement window has a distinct advantage over the sliding window.
The window frame of the fixed window is embedded in the wall, the glass is directly attached to the window frame, and the four sides of the glass and the window frame are sealed by the sealant. Under normal circumstances, the watertightness and airtightness are good, and the air is difficult to pass through the seal. The glue forms convection, so convective heat loss is minimal.
