These 2 casement windows are built for B2B buyers managing multi-opening projects. Matched to DERCHI's high-performance thermal-break aluminum family, they pair structural stability with extensive customization for glass, hardware, and finish.
- Thermal-break 6063-T5 aluminum with PA66 insulation strips
- Standard 5+27A+5mm double tempered insulated glass with argon gas
- Configurable opening modes, sash styles, and WEHAG hardware options
Product Details
Structurally, these windows utilize thermal-break 6063-T5 aluminum profiles available in 109, 118, or 127 mm frame depths. The 2.0 mm profile thickness combined with PA66 insulation strips and a standard 5+27A+5 mm double tempered insulated glass unit creates a strong barrier against heat transfer, distinguishing it from non-thermal-break alternatives.
For project applications, the system accommodates multiple opening modes including outward casement, awning, and cranked-out configurations. This flexibility allows contractors to address specific ventilation, spatial, and performance requirements across different building zones, ensuring the 2 casement windows meet specific wind pressure and sound insulation targets.
