Engineered for extreme thermal performance and minimal U-values matching the central European climatic demands.
Founded in 2006, Jiangsu Guoxin Glass Co., Ltd. has established itself as a global benchmark in the design, engineering, and mass-fabrication of premium aluminium window systems and high-specification architectural glazing.
With a stable, vertically integrated development structure spanning two decades, our factory works side-by-side with global developers, facade contractors, and local Austrian importers. By integrating German-engineered hardware, precision CNC-cut profile systems, and advanced insulating glass units (IGUs) fabricated in-house, we meet the demanding requirements of Austria's regional building laws (OIB guidelines) and the DIN EN standards.
Unlike standard window fabricators, Guoxin manages the entire supply chain. From the raw float glass tempering, multi-layer Low-E coating, and gas filling, to the structural bonding within CNC-machined structural thermal-break aluminium profiles, we maintain control over every step of production.
The Austrian construction sector is defined by some of the most stringent energy efficiency and environmental protection regulations in the European Union. In accordance with the Austrian Institute of Construction Engineering (OIB) Guidelines (specifically OIB Richtlinie 6 covering energy conservation and thermal insulation), new buildings and deep renovations must satisfy rigorous thermal performance targets.
In cities such as Vienna, Graz, Linz, and Salzburg, developers are transitioning rapidly from traditional PVC and wood systems to high-end structural aluminium window designs. While PVC represents cost-effectiveness, it fails to meet the structural integrity required for large-format, floor-to-ceiling modern architectural facades. Wooden frames, though traditional, demand extensive maintenance under the volatile Alpine and continental European climates.
Consequently, thermal-break aluminium windows have emerged as the standard for both premium residential properties and multi-story commercial projects. The Austrian market demands an overall window heat transmission coefficient (Uw) of ≤ 0.8 W/(m²·K) for passive house developments, forcing manufacturers to innovate using complex multi-cavity polyamide thermal breaks, triple-insulated glass configurations, and warm-edge spacer technologies.
Different regions in Austria present unique micro-climatic and architectural challenges that require customized, factory-engineered solutions:
The future of the window and door sector lies in the integration of smart building systems and sustainable material lifecycles:
Smart Dynamic Glass Integration: The integration of electrochromic "smart glass" technology is transforming commercial office buildings in Austria. By utilizing dry-film laminating technology, our factory-integrated smart glass allows users to adjust light transmission dynamically. This technology mitigates solar heat gain coefficients (SHGC) during summer while maximizing heat gain in winter, directly contributing to LEED and BREEAM building certifications.
Thermal Separation & Insulating Gas Infusion: To achieve U-values below 0.8 W/(m²·K), our engineering team utilizes high-density polyamide thermal breaks (up to 39mm width) filled with polyurethane insulating foam. When combined with triple glazing filled with 90%+ Argon or Krypton gas, it minimizes convection currents within the glass panes.
Cradle-to-Cradle (C2C) & Low-Carbon Aluminium: Circular economy initiatives in Austria require documentation of material recycling capabilities. Aluminium is infinitely recyclable. By optimizing our factory-level casting and extrusion processes, we prioritize the use of high-recycled-content aluminium profiles, reducing embedded carbon emissions per window unit by up to 45% compared to standard global benchmarks.
A common concern for Austrian architects and contractors sourcing materials internationally is lead time predictability and product consistency. Jiangsu Guoxin Glass Co., Ltd. addresses these pain points through a mature, vertically integrated manufacturing process.
Our facility houses advanced automated extrusion lines, modern CNC machining centers, and a fully automated glass processing plant. This integration eliminates the common issues of multi-tier supplier delays.
To optimize delivery times to Austria, we utilize the China-Europe Railway Express (CR Express). Shipping containers depart directly from Jiangsu and reach central European freight hubs in Vienna, Graz, or Linz within 15 to 20 days. This overland rail route offers a faster alternative to traditional sea freight via Hamburg or Koper, allowing us to align production milestones with tight construction schedules.
Compliance with local construction regulations is mandatory for imported products. Our products are fully tested under European Norms (EN) and certified to carry the CE mark.
Through rigorous internal testing and independent certification, our factory delivers complete technical documentation, including thermal transmittance simulations (using THERM software), structural wind load calculations (FEA analysis), and acoustic test reports.
Whether your project requires conformity to the ÖNORM B 5200 series for window installation (RAL quality installation standards) or structural glazing guidelines, our engineering department works with your project managers to ensure compliance before shipping.
