What Are DERCHI E6N Large Casement Windows?
DERCHI manufactures the E6N series of large casement windows with tilt and turn functionality for residential and commercial use. These aluminum swing windows open inward and feature thermal break technology that reduces heat transfer between interior and exterior spaces. The dual-function handle system allows users to tilt the window from the top for ventilation or turn it to open fully like a door. The inward-opening design protects against weather damage and enables cleaning from inside the building. As experienced casement window manufacturers, DERCHI constructs these aluminum swing windows with durable frames that require minimal maintenance. The E6N series offers multiple exterior profiles to match different architectural styles and works well in single installations or multi-unit projects. These swing windows provide reliable operation, weather sealing, and flexible ventilation options for various building types and climates.

Ready to Experience Premium Large Casement Windows?
Transform your space with DERCHI E6N aluminum swing windows that combine superior insulation, advanced hardware, and elegant design. Our casement window manufacturers deliver quality that stands the test of time, backed by innovative engineering and reliable performance.
Technical Performance Standards
The DERCHI E6N represents advanced aluminum swing windows designed for large openings. These casement windows deliver robust protection against water infiltration, air leakage, and wind pressure while providing sound reduction and energy efficiency. As leading casement window manufacturers, DERCHI engineered these swing windows to meet demanding performance standards for residential and commercial applications.
U-Factor - 0.23
Thermal transmission coefficient indicates heat transfer resistance through window assembly. Low U-value demonstrates energy conservation capabilities in heating and cooling. Insulated frame technology reduces thermal bridging between interior and exterior. Performance meets energy efficiency standards for building codes.
Wind Pressure Resistance - 5 KPa
Withstands wind loads equivalent to moderate storm conditions. Reinforced aluminum frame construction distributes stress loads uniformly. Tested structural integrity ensures window stability during weather events. Safety glazing systems remain secure under pressure variations.
SHGC - 0.20
Solar Heat Gain Coefficient measures solar radiation transmission through glazing. Low SHGC value reduces cooling loads in warm climate conditions. Coating technology controls solar energy while maintaining visible light transmission. Balances energy efficiency with natural lighting requirements.
Water Tightness - 700 Pa
Prevents water penetration under pressure equivalent to heavy rainfall conditions. Tested seal integrity protects interior spaces from moisture damage. Multi-point locking system creates watertight barriers at closure points. Weather sealing technology maintains performance over extended use periods.
Air Tightness - 1.2m³/(m·h)
Controls air leakage to minimize energy loss through window gaps. Precision-fitted frames reduce drafts and maintain indoor climate control. Gasket sealing systems create barriers against unwanted air exchange. Low infiltration rate supports heating and cooling system efficiency.
Sound Insulation Performance - 35 dB
Reduces external noise transmission for quieter interior environments. Multi-chamber frame design disrupts sound wave transmission paths. Glass specifications optimized for acoustic dampening properties. Sealing systems prevent sound leakage through frame connections.
