Product Overview:

Engineered to deliver monumental performance with minimalist aesthetics, this 125 mm deep‑profile sliding door system features an exceptionally slim interlock stile —the narrowest in its class. Despite a massive 3.0 mm structural wall thickness and 300 kg load capacity, the central meeting stile is dramatically reduced, transforming the door into an almost invisible glass wall. Certified to NFRC thermal standards, compatible with UL‑certified Stanley or Nabtesco electric motors, and available in pocket door configurations, this system redefines what a heavy‑duty sliding door can look like.

Key Features & Technology:

1. Slim Interlock Stile – Maximum Glass, Minimal Frame
The signature innovation of this 125 mm system is its ultra‑slim vertical meeting stile. Where conventional heavy‑duty sliders require a bulky central post, our engineered interlock profile reduces visible frame width to an absolute minimum. The result: uninterrupted panoramic views and a clean, contemporary aesthetic—without sacrificing structural integrity.

• Interlock stile width: Visually slimmer than industry standard for 300 kg systems

• Glass exposure: Maximised sightlines for residential and commercial applications

2. Ultra‑Heavy‑Duty Structural Profiles
Extruded main profiles feature a 3.0 mm wall thickness, providing exceptional rigidity for oversized panels.

• Blade width: 600 – 2500 mm

• Blade height: 1500 – 3500 mm

• Maximum panel weight: 300 kg
  Ideal for panoramic resort entrances, luxury residences, and large‑scale commercial openings.

3. Electric Automation with UL‑Certified Motors
Seamlessly integrate with world‑class automation systems:

• Stanley electric motors

• Nabtesco electric drive systems
  Both are UL 325 certified for North American safety. Choose from:

• Electronic sliding door – sensor‑activated, hands‑free access

• Pocket door configuration – panels vanish completely into the wall cavity

4. Certified North American Performance

• NFRC certification available – verified U‑values

• Water penetration resistance: 330 Pa

• Air infiltration: ≤ 1.0 cfm/ft² @ 75 Pa

• Wind load resistance: +2160 Pa design pressure

• Structural test pressure: ±2000 Pa certified

5. Thermal Break & Energy Efficiency
Continuous polyamide thermal break separates interior and exterior aluminum surfaces, eliminating condensation and thermal bridging. Whole‑system Uw value ≤ 1.7 W/m²K (NFRC ≤ 0.30 BTU/hr·ft²·°F) – compliant with energy codes across Climate Zones 4–7.

6. Acoustic Comfort
Weighted sound reduction index Rw up to 37 dB effectively reduces exterior noise – ideal for urban residences, hotels, and noise‑sensitive environments.
