Introduction
Features
Strong Wind Resistance
Miami-Dade NOA certified, the window can withstand hurricane‑force winds up to 210 km/h. Titanium-reinforced rollers ensure stable operation under full system wind loads rated at 2400 Pa.
Reliable Thermal Insulation
PA66-GF25 thermal break strips infused with aerogel maintain performance from -40°C to 88°C, reducing heat transfer (U-value ~0.82 W/m²·K, ) for superior energy efficiency.
Superior Corrosion Resistance
Hinges crafted from 316L stainless steel with 2% molybdenum and titanium pins, engineered to resist chloride-induced pitting and ensure long-term durability in coastal or corrosive environments.
customization
- Dimensions: Fully bespoke panel heights and widths to suit any opening.
