The performance of glass fireproof doors depends on the selection and matching of materials. Products with different material combinations have different focuses on adapting to different scenarios and protective effects. Understanding their material classification can better understand their fire prevention principles and scope of application. The materials of glass fireproof doors are mainly divided into three categories: fireproof glass, door frame materials, and sealing materials. The three work together to ensure the effectiveness of fire and smoke prevention.

Fireproof glass is the core component, mainly divided into three types: composite fireproof glass, poured fireproof glass, and laminated fireproof glass. Composite fire-resistant glass is composed of multiple layers of glass and a fire-resistant adhesive layer. When exposed to high temperatures, the adhesive layer foams and expands, forming a thermal and smoke barrier; Injected fire-resistant glass is made by injecting fire-resistant liquid into the glass interlayer, and the fire-resistant liquid solidifies at high temperatures to form a dense insulation layer with stable fire resistance; Metal wires are embedded inside the laminated fire-resistant glass, which not only enhances fire resistance but also prevents splashing after glass breakage, increasing safety.

The door frame material is mostly made of cold-rolled steel plate, stainless steel or aluminum alloy. Cold rolled steel plate has high cost-effectiveness and is suitable for most ordinary buildings; Stainless steel is corrosion-resistant and has a high aesthetic value, suitable for humid or high-end places; Aluminum alloy is lightweight and has fast thermal conductivity, requiring additional insulation treatment. The sealing material adopts fireproof expansion sealing strip, which maintains elasticity at room temperature and rapidly expands at high temperature, sealing the gap between the door frame and the door leaf to prevent smoke from penetrating. The reasonable combination of different materials enables glass fireproof doors to meet both fire prevention requirements and meet the usage needs of different buildings, becoming an important guarantee for building safety.
