large casement windows

The N9 Series combines tilt and turn functions with traditional casement window operation. These large casement windows feature dual opening modes - tilt inward for ventilation or swing fully open like crank out windows. The system uses reinforced aluminum frames to support expansive glass panels up to 9 square meters.

DERCHI designs the N9 for projects requiring oversized window solutions. The tilt function allows secure ventilation while the turn function provides full access for cleaning and emergency egress. As established casement window manufacturers, we engineer each unit with multi-point locking systems and thermal breaks for energy efficiency.

The N9 suits residential and commercial applications where standard casement windows large formats cannot meet architectural demands. The system accommodates various glass configurations including double and triple glazing. Each window operates with a single handle that controls both tilt and turn functions, eliminating the need for separate hardware.

Features of N9 Large Casement Windows

The N9 Series delivers performance features that set standards for casement windows large format applications. These crank out windows combine European tilt-turn technology with sizes that accommodate modern architectural requirements. DERCHI, as leading casement window manufacturers, integrates six core features into every N9 unit.

Size and Views

The N9 supports glass panels up to 9 square meters per unit. Large casement windows in the N9 series use minimal frame profiles to maximize visible glass area. The system handles heights up to 2.8 meters and widths up to 1.5 meters per sash.

Ventilation and Airflow

Dual opening modes provide ventilation control. The tilt position creates a 15-degree opening at the top for secure airflow. Turn mode opens the full window area like traditional crank out windows, allowing complete air exchange within seconds.

Easy Operation

A single handle controls both tilt and turn functions. The mechanism requires minimal force to operate casement windows large panels. The handle locks in three positions: closed, tilted, and turned. No reaching or stretching needed for operation.

Energy Efficiency

Thermal breaks in aluminum frames reduce heat transfer. The N9 achieves U-values of 1.2 W/m²K with standard double glazing. Triple glazing options further improve thermal performance. Multi-point sealing strips prevent air infiltration around the entire frame perimeter.

Security Features

Multi-point locking engages at five points along the frame. The tilt position allows ventilation while maintaining security. Reinforced hinges support heavy glass loads. Optional laminated glass and concealed hardware increase protection levels.

Customization Options

Casement window manufacturers offer the N9 in 20 standard colors and custom RAL finishes. Glass options include tinted, low-E, and acoustic configurations. Hardware choices range from standard handles to automated operators for remote control.

Performance Specifications

The N9 Series meets international standards for large casement windows performance. These crank out windows undergo testing for five critical metrics that determine quality and durability. DERCHI, as certified casement window manufacturers, ensures each unit exceeds minimum requirements for residential and commercial applications. The following specifications apply to all casement windows large format models in the N9 range.

THERMAL INSULATION

Level 6 rating at 2.0 W/(m²·K) means heat transfer measures 2.0 watts per square meter kelvin. Thermal breaks and insulated glass units achieve this U-value, helping casement windows large panels maintain consistent indoor temperatures.

WIND PRESSURE RESISTANCE

Level 9 rating at 5 kPa allows the N9 to withstand wind loads up to 5,000 pascals. Reinforced frames support this capacity for large casement windows in high-rise buildings and coastal installations.

WATERPROOF

Level 6 rating at 700 Pa ensures the N9 prevents water infiltration at 700 pascals pressure. Multi-chamber profiles and EPDM seals protect large casement windows against water penetration during severe weather, equal to hurricane-force rain resistance.

AIR TIGHTNESS

Level 8 rating at 1.2 m³/(m·h) means air leakage remains below 1.2 cubic meters per hour per meter. Multi-point locking compresses seals uniformly around crank out windows frames, reducing energy costs and eliminating drafts.

SOUND INSULATION

Level 4 rating at 35 dB reduces external noise by 35 decibels. Standard double glazing with acoustic spacers achieves this rating. Casement window manufacturers recommend this level for residential areas near moderate traffic.
