This fire-resistant glass is a composite material made by laminating multiple sheets of high-transparency, toughened float glass with nano-silica-based intumescent interlayers.
Upon exposure to intense heat, the exposed glass layer shatters. Simultaneously, the nano-silica interlayers expand up to ten times their original thickness to form a rigid, opaque black insulating barrier. This layer effectively blocks flames, intense heat, and toxic gases from penetrating to the unexposed side.
Custom dimensions and configurations are available upon request.
Product Features
Superior Thermal Insulation
Engineered with nano-silica materials and advanced manufacturing processes, the glass significantly reduces heat transmission and maintains interior temperature stability under fire exposure.
High Optical Clarity
Despite its fireproof properties, the glass maintains excellent visible light transmittance, enabling natural lighting while ensuring both functionality and aesthetics.
Excellent Fire Resistance
Certified to meet stringent fire safety standards, the product effectively prevents the spread of flames during fire emergencies, ensuring vital time for evacuation and response.
Exceptional Durability
With excellent resistance to UV radiation, oxidation, and corrosion, the glass performs reliably in diverse climatic conditions and offers an extended service life.
Environmentally Friendly
Free from hazardous materials, the product does not emit toxic gases under high heat, making it a safe and sustainable choice for building applications.
Applications
External façades, partitions, and windows in commercial buildings, office towers, shopping malls, hotels, and exhibition centers.
Fire safety-critical areas such as schools, hospitals, metro stations, and airports.
Windows and internal partitions in vehicles and vessels, providing secure and unobstructed visibility.
Especially suited for high-temperature environments such as chemical and pharmaceutical plants to safeguard personnel and equipment.
