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
Engineered with nano-silica materials and advanced manufacturing processes, the glass significantly reduces heat transmission and maintains interior temperature stability under fire exposure.
Despite its fireproof properties, the glass maintains excellent visible light transmittance, enabling natural lighting while ensuring both functionality and aesthetics.
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.
With excellent resistance to UV radiation, oxidation, and corrosion, the glass performs reliably in diverse climatic conditions and offers an extended service life.
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.
Frequently Asked Questions
Depending on the thickness (ranging from 25mm to 65mm), the insulation duration ranges from 60 minutes to 180 minutes, meeting A1.00 to A3.00 fire resistance standards.
Under intense heat, the outer glass layer shatters, triggering the nano-silica interlayers to expand up to ten times their original thickness. This forms a rigid, opaque insulating barrier that blocks flames, heat, and toxic gases.
Yes, custom dimensions and specific configurations are fully available upon request to suit your architectural or industrial project specifications.
No. Despite its heavy-duty fire protection, the glass maintains high optical clarity and excellent visible light transmittance, allowing for natural illumination.
Yes, the glass is environmentally friendly, non-toxic, and free from hazardous materials. It does not release harmful gases even when exposed to high heat.
