A fire-resistant window refers to a window that, together with the frame, can meet the requirements of fire-resistant stability and fire-resistant integrity within a certain period of time. According to the latest standards for fireproof windows, it can be divided into Class A fireproof windows, Class B fireproof windows, etc. According to the material of fireproof windows, it can be divided into steel fireproof windows, aluminum fireproof windows, plastic steel fireproof windows, etc. When choosing a fireproof window, in addition to paying attention to the price of the fireproof window, you should also pay attention to whether the manufacturer of the fireproof window is qualified.

Let's find out with Baydee Xiaobian!
Fire-resistant windows are mainly composed of window frames and glass. The window frame materials are wood, steel, stainless steel and other materials; the glass is fire-resistant glass, the difference lies in composite grouted glass and single-chip cesium-potassium fire-resistant glass. The former has good heat insulation effect , the latter does not have a thermal insulation function.
Fire window material classification
According to the different materials of the fireproof window frame, it can be divided into steel fireproof window (GFC), wooden fireproof window (MFC), steel-wood composite fireproof window (GMFC) and so on.
According to the classification of the use function of fire windows, it can be divided into fixed fire windows, movable fire windows, heat insulation fire windows and non-heat insulation fire windows, etc. Details>>

Generally, fireproof windows are made of steel, and there are also plastic steel, aluminum alloy, etc., while ordinary windows generally use aluminum alloy as the frame.
Fireproof windows have functions such as heat resistance and fire prevention, while ordinary windows do not have these functions.
The price of steel fireproof windows for buildings is higher than that of ordinary aluminum alloy windows
The difference between fireproof windows and fireproof windows
Fireproof windows mostly use steel and stainless steel frames, and internal glass must use fireproof glass. Fire-resistant window frames are mostly aluminum alloy or plastic steel, and non-fire-resistant glass can be used.
Different fire resistance standards
The fire-resistant limit time of fire-resistant windows can reach 1-5 hours, while the performance of fire-resistant windows is not so high, generally 1 hour.
