Overview
Hollow tempered fireproof glass is a high-performance safety glass designed to resist fire while providing thermal and acoustic insulation. It combines the durability of tempered glass with the fire-retardant properties of specialized interlayers, making it ideal for modern architectural applications. The glass is constructed by sandwiching a fire-resistant gel or intumescent layer between two tempered glass panes, sealed with a durable spacer. This design ensures the glass remains intact during a fire, blocking flames and smoke while maintaining transparency for safe evacuation.
Structure and Working Principle
The glass consists of multiple layers: tempered glass panes, a fire-resistant interlayer, and a sealed spacer filled with dry air or inert gas. Under high heat, the interlayer expands, forming an opaque, heat-insulating barrier that prevents fire penetration. The hollow space between the panes enhances thermal insulation, reducing energy loss in buildings. The tempered glass ensures shatter resistance, minimizing injury risks during breakage. The spacer system also prevents condensation and improves soundproofing.
Key Features
Hollow tempered fireproof glass offers exceptional fire resistance, typically rated for 30-120 minutes (EI30-EI120). It complies with international safety standards such as EN 1363-1 and GB 15763.3. Additional features include UV resistance, noise reduction (up to 40 dB), and energy efficiency due to its insulating properties. The glass is available in clear, tinted, or frosted finishes to meet aesthetic and functional requirements.
Application Areas
This glass is widely used in fire-rated windows, doors, and curtain walls for high-rise buildings, hospitals, schools, and industrial facilities. It is also employed in interior partitions, skylights, and elevator enclosures where fire safety is critical. In commercial spaces, it enhances safety without compromising design, allowing natural light penetration while meeting stringent fire codes. Residential applications include balcony railings and stairwell enclosures.
Maintenance and Precautions
Regular inspection for seal integrity and frame corrosion is essential to maintain fireproof performance. Clean with non-abrasive solutions to avoid scratching the surface. Avoid drilling or cutting after installation, as this compromises the fire rating. Ensure frames and fixings are also fire-rated to maintain system compliance. Follow manufacturer guidelines for handling and installation to prevent edge damage.
B2B Procurement Guide
When sourcing hollow tempered fireproof glass, prioritize suppliers with certifications like ISO 9001 and product-specific fire test reports. Request samples to verify clarity, thickness, and interlayer quality. Negotiate bulk discounts for large projects, but ensure lead times accommodate production and quality checks. Confirm logistics support for fragile shipments and inquire about after-sales services, such as installation support or warranty coverage.
