At present, fire-resistant windows are common: steel fire-resistant windows, aluminum fire-resistant windows, aluminum alloy fire-resistant windows and plastic steel fire-resistant windows, steel fire-resistant windows generally refer to the practice of non-insulated fire windows, aluminum fire-resistant windows such as broken bridges are generally set in the frame or skeleton of the fire-resistant windows in the steel lining or aluminum lining to increase the strength of the window, and some are also filled with castable materials to enhance the fire-resistant performance. gb/t 31433-2015 “general technical conditions for architectural curtain wall, doors and windows Article 5.1.5 of the “Technical Conditions” stipulates that: “For external doors and windows with fire-resistant integrity requirements, the glass used in at least one layer of composite GB 15763.1, plastic external doors and windows, steel-plastic composite external doors and windows, steel-plastic co-extruded windows and doors, aluminum-plastic co-extruded windows and doors profiles used to strengthen the steel or aluminum lining should be connected to form a closed frame, and take measures to prevent glass falling out of the glass in the glass mosaic notches by the fire”. Measures to prevent the glass from falling off after being subjected to fire”.
The difference between steel fireproof window and aluminum alloy fireproof window:

Aluminum alloy fire window is in recent years with the gradual standardization of high-rise building fire prevention requirements, fire prevention concepts continue to improve, people for the fire window performance more humane functionality of the common reproduction of new products. It effectively overcomes the shortcomings of the traditional steel fireproof window as a home window, and at the same time has its own significant features, both have their own strengths.
Steel fireproof window has one or two decades of application history, the stability of its product performance is indisputable, recognized by consumers. As a building fire prevention windows, especially industrial fire performance is excellent, it has a low cost and economical and practical, good fire resistance and heat insulation, widely used features, especially in recent years, movable, self-closing fire window performance continues to optimize, so that its function is more comprehensive. At this stage, high-rise residential shelter, kitchen and bedroom windows are required to have heat preservation, energy saving, fire-resistant performance, especially the airtightness, wind pressure resistance is unmatched by ordinary steel fireproof windows. At the same time, aluminum alloy fire-resistant windows are novel in appearance, not easy to corrode, and have a long service life, which is more suitable for home fire prevention requirements.
