Fire resistant window fire resistance limit: Class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, and Class C window is not less than 0.6 hours.
Technical requirements: 1. Materials and accessories (1) the window frame frame adopts a steel frame or wooden frame with certain strength to ensure the integrity and stability of components. (2) galvanized steel plate or stainless steel plate can be used for steel frame and layering. The material selection standard conforms to the provisions of Article 5.1 in GB12955 general technical conditions for steel fire doors. (3) the material selection standards of wooden frames and layering shall conform to the provisions of Article 5.1.1 in GB14101 general technical conditions of wooden fireproof door. (4) incombustible materials should be used for filling materials inside steel and wood frames. (5) fire-proof glass can be selected with products that do not affect fire resistant window fire resistance test. The transmittance of the glass shall not be less than 75% of the sheet glass of the same layer. (6) the sealing material between the frame and the fire-proof glass should be flame-proof material, which can play the role of fire-proof and smoke-proof in fire. (7) hardware accessories should be qualified after testing the shaping supporting products. II. Installation requirements: 1. Party A shall carefully check whether the quantity, specification, grade and various accessories are qualified and complete according to the supply contract when receiving the goods. 2. Storage and storage fire resistant window should be stored vertically in a dry room with anti-corrosion measures. Glass should be shelved and relied on objects that cannot damage the glass edge and glass surface. 3. Installation (1) fire resistant window must be checked before installation. If the window frame, Casement warpage, deformation, and glass damage are caused due to careless transportation and storage, the installation can be carried out only after repair. (2) when installing fire resistant window, the verticality of the front, back, left and right shall be corrected by horizontal ruler leveling or hanging line method, so as to be horizontal, vertical, and high and low. (3) the window frame must be integrated with the building, Use wood or iron to connect with the wall. After the steel window frame is installed, cement mortar must be poured between the window frame and the wall, and it can be used normally after maintenance for more than 24 hours. (4) the position of hardware accessories mounting hole should be accurate, so that the hardware accessories can be installed smoothly and firmly to meet the use requirements. (5) when installing fire-proof glass, the joints on the four sides should be kept evenly. After positioning, fill and fill the gaps on the four sides with fireproof cotton, and then seal the edge banding. (6) in addition to the above requirements, the installation shall be carried out in accordance with the requirements of engineering construction and acceptance code.
If the height of the windowless wall is less than 0.80m and the height of the window sill wall is less than 0.80m, fire-resistant poles should be set on the outer edge of each floor.
No less than 1.00h, no less than 0.80m height non-burning solid skirt wall or fireproof glass skirt Wall

You can ask the fire center what documents have such rigid rules.
Technical Specification for application of building glass JGJ113-2003. There are detailed regulations in it. Composite fireproof glass:
Good heat insulation: it can effectively reduce internal heat radiation and heat transfer. It can be used in some places requiring fire prevention and heat insulation.
Good sound insulation: it can effectively reduce the interference of various noises such as vehicles, planes, trains, etc.
High transparency: it can basically maintain the transparency of the original glass.
Application scope:
Fireproof capacity partition
Fireproof glass door
Fire screen
Fireproof glass window
Building atrium fire barrier
Steel or wooden fireproof door.
