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.

The N9 Series meets international standards for large casement windows performance.

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.

Application Scenarios

The N9 Series serves both commercial and residential markets requiring large casement windows. These crank out windows adapt to various architectural requirements from office buildings to luxury homes. DERCHI, as experienced casement window manufacturers, designs the N9 for projects demanding oversized openings with dual functionality. The following applications demonstrate where casement windows large formats deliver optimal performance.

Commercial

Modern commercial buildings require windows that balance aesthetics with functionality. The N9 provides floor-to-ceiling glass installations for offices, hotels, and educational facilities. Large casement windows maximize natural light while reducing energy costs. The tilt function ensures controlled ventilation without compromising security. Crank out windows meet commercial building codes for emergency egress. Multi-point locking systems protect valuable assets. The N9's wind resistance rating suits high-rise installations. Casement window manufacturers specify these systems for projects requiring durable, low-maintenance solutions.

Residential

Homeowners choose the N9 for rooms requiring maximum light and ventilation. Living spaces benefit from panoramic views through casement windows large glass panels. The dual opening modes provide flexibility for different weather conditions. Tilt position offers secure night ventilation in bedrooms. Full opening creates indoor-outdoor connections for entertaining. Single-handle operation simplifies daily use for all family members. The N9's thermal performance reduces heating and cooling costs. These crank out windows complement both contemporary and traditional architectural styles.
