Fixed windows: Fixed windows cannot be opened. Generally, Casement is not set. The glass can only be fixed on the window frame. Sometimes Casement is set to produce the same facade visual effect as other windows, but the Casement is fixed on the window frame and cannot be opened.
Fixed windows is only used for lighting and observation, and is usually used in occasions where only lighting is considered without ventilation.
Because Casement is fixed, the glass area can be slightly larger.
The use of fixed windows is to ensure that the ventilation is not affected. Because the cost of fixed windows is much less than that of the window area, and the sound insulation and heat insulation are better than those of the open fan.
Fixed windows abandoned the influence of window frame on visual effect, plus aluminum spacing strip, making the window area more neat and beautiful.
Living room, large jump floor, study and other places mostly adopt fixed windows to ensure that the lighting area can be expanded as much as possible under the condition of sound insulation and heat insulation.
