Key Features

• Thermal Break Energy Efficiency — PA66GF25 thermal break strips + multi-chamber design deliver a whole-window U-Factor as low as 1.0–2.0 W/(m²·K), keeping rooms warm in winter and cool in summer while reducing HVAC costs.
• Multi-Chamber Profile Design — 3–5 chambers combine strength with insulation; hidden drainage and pressure-equalization cavities prevent water leakage in heavy rain.
• Flexible Glazing Options — 5+12A+5 double glazing, triple glazing, Low-E / double-silver Low-E and argon gas filling to meet energy, acoustic and solar control needs.
• Multi-Point Locking Hardware — 304 stainless steel hinges with multi-point locking for anti-theft security; ergonomic handles with smooth operation; tilt & turn mode for safe ventilation.
• Multi-Seal Gasket System — EPDM gaskets provide multi-seal protection with air permeability Class 8 and water tightness Class 6, keeping out dust, water and noise.
• Multiple Opening Styles — inward, outward, top-hung and tilt & turn options to suit different spaces and ventilation needs.
• Diverse Surface Finishes — anodizing, powder coating, PVDF coating and wood-grain transfer; colors customized per RAL chart, weather and UV resistant.
• Full Customization — size, color, glazing, hardware and opening style all customizable; OEM/ODM private label supported.

Assembly & Installation

Installation steps

• Measure the opening — verify actual opening dimensions, level and plumb before installation
