Our state-of-the-art production facility houses multiple advanced production lines, each equipped with cutting-edge technology. We deliver high-reliability insulated glass systems tailored to European building configurations.
Building Trust and Excellence for Over Two Decades
Jiangsu Guoxin Glass Co., Ltd. was founded in 2006 and has since grown into a leading enterprise in the glass 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 aluminum windows, fireproof Glass, laminated glass, and insulated glass. This expertise has allowed us to innovate and produce high-quality products that meet the diverse needs of our customers.
In Spain's current structural design landscape, the Código Técnico de la Edificación (CTE) dictates stringent directives regarding energy efficiency (specifically documents DB-HE1 on energy limitation and DB-HE4 on thermal insulation parameters). With Spain split into diverse meteorological climate zones (spanning Zone A in the warm southern Andalusia to Zone E in the cold mountainous terrains of Castile and León), specialized double and triple insulated glass units (IGUs) are no longer luxury components—they are mandatory structural elements.
To comply with maximum permitted thermal transmittance rates ($U$-values) which are capped as low as $1.8\text{ W/m}^2\text{K}$ in demanding northern locales, local developers require high-end Low-Emissivity (Low-E) coatings combined with inert gas cavities (typically filled with 90% Argon). For Mediterranean zones such as Barcelona and Valencia, solar control glass with reduced Solar Factor ($g$-value) parameters is key to minimizing structural cooling loads during peak summer periods.
On a global scale, the structural glass market is pivoting rapidly toward complete decarbonization, circular economies, and low-embodied-carbon supply channels. Architects across Madrid, Seville, and Bilbao are now demanding verified Environmental Product Declarations (EPDs). By synthesizing advanced automation in China's top-tier production centers with regional distribution hubs across the Iberian peninsula, Guoxin Glass bridges this supply chain gap.
Our raw materials are processed via computerized tempering and automated gas filling lines, ensuring a durable double-barrier seal that protects against edge-seal failures—the leading cause of premature failure in high-humidity coastal zones like Malaga and Alicante.
The applications for modern double-glazed units in Spain fall into three main archetypes:
The transition toward building-integrated photovoltaics (BIPV), vacuum insulated glass (VIG) featuring ultra-low profiles, and chromogenic smart glass elements forms the technical trajectory of our R&D. Guoxin Glass is continuously innovating to deliver next-generation triple-glazed units featuring lightweight composite spacers that lower overall facade weight by up to 15% while improving edge-zone thermal values by 20% compared to traditional metallic spacers.
Engineered for seamless integration with Spanish thermal break frames (Rotura de Puente Térmico - RPT).
Combining artistic expression with sub-surface optical laser engraving technologies for premium partitions and architectural highlights.
Trusted globally, optimized for regional Spain performance parameters.
