- 5+27A+5 mm double tempered insulated glass with argon gas and PVDF spacer
- Project-customizable glass, WEHAG hardware, color finishes, and screen options
Product Details
The three-section aluminum window structure typically features a fixed center lite flanked by operable side casements, though three vertical lites with one or two operable panels are also available. Operable lites use an outward opening mechanism, while non-operable sections hold fixed glass. The frame-depth family of 109/118/127 mm and 2.0 mm profile thickness provide structural stability for varied opening sizes.
Core technology centers on thermal-break 6063-T5 aluminum paired with a PA66/DERCHI insulation strip and argon-filled double insulated glass casement window units using PVDF aluminum spacers. This configuration reduces heat transfer compared to ordinary aluminum frames. Multi-point locking and project-level glass, hardware, and screen upgrades allow the window to meet specific energy, ventilation, and facade-design requirements.

Customizable Styles
Glass Configuration: Upgrade from standard argon glass to Low-E, laminated, triple, tinted, reflective, frosted, or bullet-proof options based on project climate and security needs.
Frame Color: Select from Pearl White, Quartz Gray, Starry Sky Black, Deep Coffee, wood-grain finishes, and PVDF custom colors with applicable upcharges.
Size and Layout: Choose single sash, double sash, side-opening with center-fixed, or three-section combinations within engineering limits and series constraints.
Opening Direction: Configure left, right, or both-side operable lites with outward or top-hung hardware to match room layout and ventilation strategy.
Screen and Safety: Add anti-theft, 304 stainless steel mesh, diamond mesh, or 48-mesh high-transparency screens with optional safety fences for added protection.
Hardware Accessories
WEHAG Handle: Available in black or silver finish with an ergonomic grip designed for smooth and comfortable daily casement operation.
WEHAG Hinge: Engineered specifically for outward-opening sashes, providing load stability and consistent operational durability over time.
Multi-Point Lock: Black two-point or six-point locking system selected by series to enhance window security and improve sealing pressure.
Casement Limiter: Simple or safety limiter options control the opening angle, protecting against sudden wind gusts and restricting access.
Sealing and Screen: EPDM sealing strips pair with optional 304 stainless steel mesh or diamond mesh screens for insect protection and ventilation control.
