Inside our 25,000m² intelligent production hub: Full visibility into precision extrusion processing, automated CNC machining, strip threading, manual assembly, and rigorous testing racks.


















As carbon-neutral mandates redefine the building envelope industry, aluminum glass window engineering is shifting toward ultra-low U-values, smart glazing, and structural integration.
Traditional structural isolation relies on standard Polyamide (PA66 GF25) strips. The next generation incorporates micro-porous silica aerogel core fill into multi-cavity profiles. This innovation lowers profile thermal conductivity ($\lambda \le 0.030 \text{ W/m}\cdot\text{K}$), pushing overall window U-factors down to Passive House levels ($U_w \le 0.8 \text{ W/m}^2\cdot\text{K}$).
Modern architectural facades are transitioning from passive physical barriers to active energy generators and daylight modulators. Integrated Building Photovoltaic (BIPV) glass units combined with electrochromic dynamic tinting allow users to adjust solar heat gain coefficient (SHGC) dynamically between 0.09 and 0.60 based on ambient sunlight.
By shifting to 80%+ post-consumer recycled primary aluminum without compromising yield strength (minimum tensile strength $\ge 205 \text{ MPa}$), our extrusions deliver maximal wind-load deflection performance ($L/175$ to $L/300$ standard limits) while achieving a 70% lower embedded carbon footprint per profile.
Tailored fenestration engineering matrices formulated to address unique structural, thermal, and regulatory requirements across global climatic zones.

Key technical answers for facade consultants, architectural procurement managers, and structural engineers.
Our architectural systems hold full CE compliance under EN 14351-1 standards, covering air tightness, water resistance, and structural load deflection. For the North American market, our systems carry NFRC thermal performance ratings and AAMA/WDMA/CSA 101/I.S.2/A440 compliance for air infiltration, water entry, and hurricane impact resistance (ASTM E1886/E1996 Level D).
Thermal break profiles utilize structural Polyamide strips (PA66 GF25) to isolate the exterior aluminum extrusion from the interior section. By breaking the high thermal conductivity of metal ($\approx 200 \text{ W/m}\cdot\text{K}$ down to $0.3 \text{ W/m}\cdot\text{K}$ across the strip), our windows achieve total assembly thermal transmittance ($U_w$) values as low as $0.8 \text{ to } 1.4 \text{ W/m}^2\cdot\text{K}$, significantly reducing energy loss in extreme climates.
Yes. Our in-house engineering team of 42 active R&D personnel delivers comprehensive CAD shop drawings, elevation details, section cuts, structural wind load calculations (evaluated in Pascals according to project height and regional wind speed), and Revit BIM models prior to production release.
Our 35-inspector QC team subjects 100% of finished window units to corner strength testing, hardware cycling checks, and water spray tests. Products are packaged using protective film layer wrapping, corner guards, plastic moisture barriers, and custom steel-framed stillage crates to guarantee damage-free sea freight under DDP or CIF terms.
