I don't know how big the window of the house I bought is. What are you calling about?

Call the developer or the property. Generally speaking, the width of the window should be half of the width of the room, and the height of the window should be determined according to the height of the house. Generally, the windowsill is 900mm high, and the height of the top surface of the window is 300 ~ 600 mm from the ground. For example, in a house with a width of 3.6 meters and a height of 2.8 meters, the window specification is best: width × height = 600mm 2. For an office building with a bay of 3.6 meters and a floor height of 3.6 meters, the window specification should be: width× height =1.8.

1 The protective height of the low windowsill shall meet the following requirements:

1) When the height of low windowsill is less than 0.5m, the height of guardrail or fixed fan shall be counted from the windowsill surface;

2) When the height of low windowsill is higher than 0.5m, the height of guardrail or fixed fan can be calculated from the ground. However, within the height range of 0.5m below the guardrail, no horizontal fence or any other treadable part shall be set. If there is a treadable part, its height should be calculated from the treadable part;

3) When the indoor and outdoor height difference is less than or equal to 0.6m, the first floor low window sill can be undefended.

2 The protective height of the bay window (bay window) low windowsill shall meet the following requirements:

1) There is a wide windowsill for people to sit or place flowerpots in the bay window, and the protective height of the guardrail or fixed window is calculated from the windowsill surface;

2) When there is no wide windowsill in the bay window and the guardrail is set near the inner wall of the bay window, it can be implemented according to the provisions of the low windowsill.
