Explore our certified OEM fire guard glass assemblies, radiation shielding panels, energy-efficient curved insulated units, and specialized structural glass engineered for international building codes.
In modern structural engineering, the integration of passive fire protection within commercial, industrial, and high-occupancy residential environments has evolved from a regulatory requirement into a core element of architectural design. Global urbanization, strict municipal fire codes, and the increasing complexity of contemporary high-rise facades necessitate advanced fire guard security systems that combine high thermal resistance, mechanical durability, and optical transparency.
As a premier source manufacturer, Jiangsu Guoxin Glass Co., Ltd. delivers custom OEM (Original Equipment Manufacturer) and ODM solutions tailored to rigorous global standards, including ASTM E119, UL 10B/10C, EN 1363, EN 1634, and BS 476. By leveraging state-of-the-art float glass processing, multi-layer laminating technology, and advanced aluminum fenestration engineering, we provide comprehensive protection across structural glass partitions, curtain walls, emergency egress corridors, and critical facility security zones.
Founded in 2006, Jiangsu Guoxin Glass Co., Ltd. has grown into a leading enterprise in the international glass manufacturing sector, maintaining an unbroken track record of operational stability, technical innovation, and product reliability for over two decades. Our company has accumulated deep expertise in the research, development, custom fabrication, and global distribution of high-performance aluminum windows, fireproof glass, SGP/PVB laminated glass, and double/triple insulated glass units (IGUs).
Our facility operates state-of-the-art, automated production lines capable of precise thermal tempering, exact CNC edge grinding, automated cleanroom lamination, and robotic insulating assembly. This technological infrastructure enables us to fabricate complex specialized products—such as jumbo-size structural glass, curved fire-rated glazing, radiation-shielding lead glass, and architectural decorative pattern panels—with microscopic precision.
Our multidisciplinary engineering team is composed of seasoned professionals with deep backgrounds in inorganic materials science, structural mechanics, and fire-safety engineering. This deep technical foundation empowers us to pioneer advanced composite glass structures that provide robust structural integrity, superior thermal insulation, sound attenuation, and blast/fire containment.
Embracing our core tenets of "Quality First, Customer First, and Credit-Based Operations", every glass panel that leaves our production floor undergoes rigorous quality assurance. From raw float glass inspection to ultrasonic interlayer gap analysis and pyrometric fire endurance testing, we ensure uncompromising quality control for global compliance.
Equipped with horizontal convection tempering furnaces, high-pressure autoclave chambers, and automated double-edging production lines, Guoxin guarantees high flatness, minimal optical distortion, and precise dimensional tolerances across standard and custom OEM product lines.
To make informed procurement decisions, architects, structural engineers, and fire safety contractors must evaluate fire-rated glass based on European (EN) and North American (UL/ASTM) performance classifications. Fire safety glazing is categorized into three primary structural operational modes:
| Classification Type | Integrity (E) | Radiation Control (EW) | Thermal Insulation (EI) | Typical Fire Duration | Primary Applications |
|---|---|---|---|---|---|
| Class E (Integrity Only) | Prevents flames & hot gases | No thermal radiation control | No conductive insulation | 30, 60, 90, 120 Mins | Non-insulating fire doors, exterior windows with spatial separation. |
| Class EW (Integrity & Radiation) | Prevents flames & hot gases | Limits heat radiation < 15 kW/m² | Partial thermal shielding | 30, 60 Mins | Corridor partitions, stairwell enclosures, fire barrier doors. |
| Class EI (Integrity & Complete Insulation) | Prevents flames & hot gases | Blocks thermal radiation completely | Maintains back face < 140°C rise | 30, 60, 90, 120 Mins | Fire escape corridors, hospital safe zones, data center fire walls. |
Our flagship EI-Rated Fire Guard Security Glass incorporates clear, hydrated sodium silicate or aqueous gel interlayers sandwiched between tempered or heat-strengthened glass plies. When exposed to heat exceeding 120°C, the inner interlayer reacts pyrometrically: it expands and transforms into a opaque, rigid foam thermal shield. This endothermic reaction absorbs huge thermal energy, blocks radiant heat transmission, and maintains structural containment even under intense thermal shock.
Specially processed float glass subjected to chemical ion-exchange tempering. Provides high mechanical strength and withstands intense thermal stress, preventing premature cracking under localized flame exposure. Excellent for Class E applications.
Multi-layered glass units containing clear hydro-gel interlayers. Delivers up to 120 minutes of full EI insulation, ensuring safe human touch temperature on the non-fire side during severe fires.
A fire guard security system is only as strong as its frame integration. Jiangsu Guoxin Glass Co., Ltd. manufactures integrated fenestration systems where fire-resistant glass units are paired with heavy-duty, thermal-break aluminum profiles, steel-reinforced frame cores, and high-durability swellable intumescent gaskets.
We provide complete OEM customization for aluminium casement windows, tilt-turn window designs, heavy-duty sliding systems, and ultra-slim fixed curtain wall systems. Custom powder coating, anodizing, and PVDF coatings ensure seamless architectural matching.
Integrating SentryGlas® (SGP) ionoplast interlayers provides 5x the tear strength and 100x the rigidity of conventional PVB, ensuring that structural glass partitions remain upright even if individual glass plies shatter during emergency events.
Combine fire guard properties with Low-E energy efficiency coatings, acoustic dampening acoustic PVB interlayers, radiation shielding lead glass elements, or decorative fluted and patterned designs within single composite IGU assemblies.
With 20 years of production and export experience, Jiangsu Guoxin Glass Co., Ltd. has established an extensive global distribution network spanning North America, the European Union, the Middle East, Southeast Asia, and South America. As a trusted source factory in China, we handle turnkey international logistics, including sea-freight reinforced wooden crating, moisture-proof vacuum packing, and custom container loading for oversized jumbo panels.
Our products are installed in iconic commercial high-rises, international airport terminals, data facilities, medical centers, and high-security government complexes worldwide, earning international praise for quality, compliance, and structural resilience.
Fire Guard Security systems must be customized to meet the environmental and operational pressures of diverse build sectors:
Large-format glass smoke barriers, fire-rated elevator lobbies, and floor-to-ceiling atrium partitions that prevent vertical flame propagation while maximizing daylight transmission.
Combined x-ray radiation shielding lead glass integrated into fire-resistant door vision panels for hospital operating rooms, diagnostic centers, and linear accelerator vaults.
High-security EI120 insulation glass walls designed to isolate high-voltage control rooms and server banks against catastrophic thermal events and electromagnetic interference.
Energy-efficient insulated glass units matching thermal break aluminum sliding and tilt-turn windows that offer high security, noise isolation, and compliance with wildfire zones.
As architectural designs push the boundaries of structural transparency and thermal efficiency, Jiangsu Guoxin Glass Co., Ltd. is continuously expanding its R&D initiatives. Our product development roadmap focuses on three technological pillars:
Next-generation nanocomposite gel layers offering ultra-high optical clarity (>88% VLT), thinner profiles, and enhanced UV stability, preventing yellowing over decades of sunlight exposure.
Combining switchable dynamic tinting privacy glass with certified fire-barrier layers, offering intelligent solar control and instant privacy for executive suites and emergency response centers.
Developing light-weight, multi-ply SGP laminated structures engineered for blast containment, hurricane impact resistance, and extreme fire endurance in extreme environment applications.
