Technical and Functional Description
Fire-resistant windows can be classified into two types based on their functional use: fixed sashes and operable sashes. Fixed-sash fire-resistant windows cannot be opened; under normal conditions, they provide natural lighting and protect against wind and rain, while in the event of a fire, they help to prevent the spread of flames. Operable-sash fire-resistant windows, on the other hand, can be opened and closed; in the event of a fire, they automatically close to inhibit flame propagation, and when open, they facilitate smoke exhaust. Under normal circumstances, they also allow for natural lighting and protection from wind and rain. To enable the sashes of fire-resistant windows to be opened and closed, both automatic and manual operating mechanisms must be installed.
Fire-resistant windows are classified into Class A and Class B based on their fire-resistance rating, with Class A having a fire-resistance limit of 1.5 hours and Class B a limit of 1.0 hour.
Material Selection and Explanation
Thermal-insulated, fire-resistant windows are constructed from galvanized steel sheets and fire-rated laminated composite glass, serving as a fire barrier to isolate and prevent the spread of fire. The sealing material between the frame and the fire-rated glass is made of flame-retardant materials, which effectively contain fire and smoke in the event of a blaze.
