N9 Series Large Casement Windows Introduction
DERCHI engineers the N9 series for buildings requiring large casement windows. The 2.0mm aluminum profile supports fixed glass panels up to 12 square meters and sashes up to 130 kilograms.
Users operate these crank out windows using Winkhaus handles and a 180-degree tilt-turn mechanism. This hardware system integrates with multi-point magnetic locks to secure the sash and manage indoor airflow.
As direct casement window manufacturers, DERCHI tests each unit to exact structural standards. The N9 frame resists wind loads up to 5,000 pascals, prevents water infiltration at 700 pascals, and cuts sound transmission by 35 decibels.
Features of N9 Large Casement Windows
The DERCHI N9 series provides structural, thermal, and functional solutions for large-scale window applications. As an established manufacturer, DERCHI engineers these tilt-and-turn units to meet strict architectural standards. The system integrates six measurable performance features for modern buildings.
Maximum Dimensions
The N9 framework supports glass areas up to 9 square meters. Individual sashes accommodate heights of 2.8 meters and widths of 1.5 meters. Slim aluminum profiles increase the total visible glass area.
Dual Ventilation Modes
The hardware enables two opening methods. The tilt function creates a 15-degree top opening for secure, continuous airflow. The turn function opens the entire sash inward for rapid air exchange.
Single-Handle Control
One handle operates all window mechanisms. Users can lock the sash in closed, tilted, or turned positions. The engineered hardware reduces the physical force needed to move heavy glass panels.
Thermal Performance
The aluminum frames incorporate thermal breaks to block heat transfer. Standard double glazing achieves a certified U-value of 2.0 W/m²K. Continuous multi-point sealing strips prevent air leaks along the frame perimeter.
Structural Security
The system utilizes five distinct locking points along the frame. The 15-degree tilt position maintains exterior security during ventilation. Heavy-duty hinges support the structural load of the glass.
Manufacturing Configurations
DERCHI offers 20 standard colors and specific RAL finishes. Glass configurations include low-E, tinted, and acoustic variations. Clients can select manual handles or integrate automated hardware for remote operation.

Performance Specifications
This section outlines the tested performance metrics for the N9 window. These specifications detail water resistance, air tightness, sound reduction, thermal efficiency, and structural wind resistance capabilities.
Thermal Insulation
Achieves a heat transfer rate of 2.0 Watts per square meter Kelvin (Level 6 rating). This metric confirms the window retains interior temperatures. It lowers building energy consumption by reducing reliance on heating and cooling systems.
Wind Pressure Resistance
Engineered to tolerate structural wind loads up to 5 kilopascals (Level 9 rating). This rating proves the window frame maintains integrity and safety during severe weather and high wind conditions.
Waterproof Performance
Tested to withstand water pressure up to 700 Pascals (Level 6 rating). This metric indicates the window prevents water ingress during rain events, protecting building interiors from moisture damage.
Air Tightness
Measures an air leakage rate of 1.2 cubic meters per meter per hour (Level 8 rating). This value demonstrates the window blocks drafts and stops uncontrolled outside air transfer, maintaining indoor climate control.
Sound Insulation
Provides a noise reduction of 35 decibels (Level 4 rating). This specification shows the window decreases exterior noise transmission. It creates quiet interior environments by blocking traffic and neighborhood sounds.
