Explore our foundational range of performance engineered windows and high durability safety glazing systems, optimized for international builders and project specifiers.
A Technical Whitepaper on Custom German Aluminium Windows & Systems integration.
Thermal bridging is solved via multi-chambered polyamide thermal barriers (e.g., Technoform structure) inserted between internal and external aluminium profiles. This reduces overall frame U-factor ratings (Uf) below 1.3 W/m²K, making them compatible with strict passive house parameters.
The synergy between high-performance glazing and rigid frames is paramount. Our integrated lines handle low-emissivity (Low-E) insulated glass units filled with 90% Argon, featuring warm-edge spacers that eliminate condensation while improving peripheral U-values.
Equipped with original German tilt-turn hardware mechanisms, our custom aluminium windows are cycle-tested up to 50,000 operations, ensuring absolute operational security, air tightness (Class 4 EN 12207), and resistance to wind load (Class C5 EN 12210).
Our state-of-the-art production facility houses multiple advanced production lines, each equipped with cutting-edge technology.
Jiangsu Guoxin Glass Co., Ltd. was founded in 2006 and has since grown into a leading enterprise in the glass and architectural fenestration industry, with a stable and successful track record spanning two decades. Our company has accumulated a wealth of experience in the research and development, production, and marketing of high-performance aluminium windows, fireproof Glass, laminated glass, and insulated glass.
By utilizing a fully integrated vertical production system—from advanced glass tempering and laminating to structural aluminium assembly—we ensure that every customized window order satisfies rigorous international standards for safety, thermal efficiency, and wind load resilience.
This allows us to produce a wide variety of high-quality glass doors and windows with remarkable precision and efficiency.
Combining artistic innovation with industrial precision for monuments, landscapes, and custom corporate installations.
Providing high-efficiency custom facade structures engineered for commercial, civic, and passive residential landscapes.
By optimizing glass coatings and using premium insulating spacers, we help project developers achieve Net-Zero energy certifications. Triple glazed low-E configurations maintain internal climate stability regardless of extreme outdoor temperatures.
For coastal and high-velocity hurricane zones (HVHZ), we combine impact-resistant SGP laminated glass layers with heavy-duty structural alloy frames, guaranteeing structural survival against windborne debris and high atmospheric pressures.
Urban density requires acoustic shielding. Utilizing asymmetric laminated glass designs coupled with multi-chamber EPDM compression gaskets, our German-system windows reduce ambient sound transmission by up to 48dB.
A testament to our structural integrity, custom manufacturing capacity, and aesthetic versatility across world-class architectural landmarks.
Recognized as the world's "largest purple clay pot shaped building," this structure is 38.8 meters high. It integrates high-precision curved structural aluminium frames with customized stained glass segments, maintaining a flawless spherical profile with variable structural angles.
Handling a daily waiting capacity of over 120,000 passengers, this high-exposure transit hub utilized thousands of square meters of our specialized high-impact laminated glass. The structural glazing ensures long-term seismic protection and meets rigorous safety protocols.
Standing at 450 meters (1,480 ft), this landmark tower is clad in our premium high-performance insulated glass units. The insulated glass provides thermal regulation, wind-load stability at extreme altitudes, and maintains architectural transparency.
Integrating advanced daylighting algorithms, this facade manages solar heat gain dynamically. The system adjusts performance metrics depending on season and time of day, optimizing internal temperature without needing mechanical blinds.
Using triple-insulated solar control glass units, this project achieved a thermal recovery rate exceeding 80%. Integrating heating, cooling, and acoustic controls directly within the window boundary set new architectural standards.
This shopping center utilizes smart laminated glass configurations to combine high transparency with active media projections, transforming the facade into a dynamic aesthetic element without compromising structural stability.
Integrating 15,000 square meters of highly polished reflective glass panels, the building reflects its parkland surroundings, minimizing its apparent physical footprint. The customized safety glass supports high mechanical loads.
Featuring oversized, high-transparency reflective insulated panels, the automobile showroom facade maximizes natural daylighting while protecting high-value vehicles from UV deterioration through advanced solar control coatings.
Our company is built on the values of "Quality First, Customer First, and Credit-Based." We understand that every modern development project presents unique parameters. Our engineering teams work alongside architects to create bespoke profile extrusions, customized thermal barrier spaces, and performance-tuned glass pairings.

Addressing structural, thermal, and logistics queries from architects, quantity surveyors, and project managers.
Unlike standard windows, a German system window is designed as an integrated unit. Every component—profile geometry, thermal break strips, multi-point locking hardware, and EPDM gaskets—is designed to work together to achieve certified U-values, wind resistance, and water tightness.
Aluminium is a highly conductive metal. To prevent heat loss, a low-conductivity polyamide barrier is mechanically crimped between the interior and exterior profiles. This "breaks" the path of thermal transfer, lowering heating and cooling expenses.
By sourcing from factories like Jiangsu Guoxin, you gain access to localized raw materials and efficient production lines. We use advanced CNC machinery and follow ISO quality management, allowing us to offer European-spec windows at competitive prices.
For standard profile systems (e.g., 65/70/80 series with standard powder coating), our MOQ is minimal. For bespoke architectural profiles requiring new extrusion dies, the MOQ depends on profile weight and project scope. Contact our team to discuss your requirements.
