Integrated System Windows

Modern architecture demands windows that balance aesthetics, performance, and adaptability — and that’s where our integrated system range excels. Drawing from years of fenestration expertise, we offer solutions that combine clean lines with exceptional thermal and acoustic control. For projects requiring lightweight strength and a contemporary look, our Aluminum Alloy System Windows deliver slim sightlines and corrosion resistance. When luxury and timeless appeal are essential, Premium System Windows provide hand-finished frames with advanced multi-point locks. In automated homes and commercial buildings, Smart System Windows offer motorized operation and integration with building management systems. Meanwhile, Energy-saving System Windows significantly cut heat transfer through low‑E coatings and thermal breaks. Every category shares the same DNA: precision engineering and rigorous testing to form a truly integrated building shell.


Integrated System Windows embody a complete approach to fenestration design, where frame, glass, and hardware work together as a single cohesive unit. Each window is fabricated using high‑grade polyamide‑reinforced profiles, triple‑seal gaskets, and fusion‑welded corners that eliminate thermal bridges. Integrated System Windows achieve air permeability ratings as low as 0.5 m³/h·m² (Class 4) and water tightness above 600 Pa, making them suitable for exposed high‑rise and coastal installations. The locking mechanism is fully concealed within the sash, maintaining the minimal visual footprint while providing security up to RC3 level. For glazing, we utilize double or triple insulating glass units with warm‑edge spacers, which push the whole‑window U‑value down to 0.8 W/m²K in select configurations. The result is a silent, draft‑free interior environment that requires less heating and cooling year after year.

Key Performance Parameters

  • Frame construction: multi‑chamber uPVC, uPVC/aluminum composite, or full aluminum with 34 mm thermal breaks
  • Hardware: concealed 6‑point locking with tilt‑before‑turn or tilt‑only function
  • Glazing options: 24 mm to 48 mm IGU, double or triple pane, argon‑filled, low‑E (emissivity ≤ 0.03)
