Narrow Casement Window

Color Options for N2 Series Narrow Casement Window

For the N2 Series narrow casement window, color selection supports exterior coordination and interior consistency. DERCHI groups finishes into PVDF coating and stock colors. This structure helps define scope for narrow frame casement windows, inward swing casement windows, and double glazed casement windows projects. It also supports planning for a narrow casement window replacement when matching existing frames.

PVDF (Fluorocarbon Coating)

PVDF is used for outdoor exposure and UV impact control. It supports stable finish performance in demanding environments.

Options include Retro Green and Mint Gold.

Stock Colors (Standard Colors)

Stock colors provide 10 options across woodgrain, dark tones, gray/stone tones, and light tones. This supports consistent specification across elevations and unit types.

Woodgrain: Huanghua Pear, Black Walnut.

Dark: Black Skin, Deep Coffee, Deep Sea Blue, Caramel Coffee, Starry Sky Black.

Gray/stone: Black Crystal Stone, Quartz Gray.

Light: Pearl White.

Opening Options for N2 Series Narrow Casement Window

The N2 Series narrow casement window supports two opening modes in one hardware set. This approach fits many narrow frame casement windows and double glazed casement windows plans. It also helps when specifying an inward swing casement window for new builds or a narrow casement window replacement.

Tilt mode opens the sash at the top while the bottom stays fixed. This mode is used for light airflow. It helps limit rain entry and reduces the risk of children or pets reaching the opening.

Turn mode opens the sash inward like a door. This gives full opening for airflow. It also supports exterior glass cleaning from inside the room.

Tilt-and-turn combines both modes in one system. The user switches modes by changing the handle position. This supports daily ventilation needs and full opening when required.

Glass Options for N2 Series Narrow Casement Window

The N2 Series narrow casement window uses insulated glass options to support thermal control, sound control, solar load control, and safety. These selections are used across narrow frame casement windows, inward swing casement windows, and double glazed casement windows. They also help align performance targets in a narrow casement window replacement scope.

Double Pane Tempered Clear Glass is the base configuration. It uses two tempered panes with an air space. It supports standard insulation and sound reduction. It is a fit for mild climates and cost control.

Low-E Glass adds a thin metal oxide layer on the glass surface. It reflects heat radiation. It helps reduce heat gain in summer and heat loss in winter. It also blocks over 70% of UV, which helps reduce fading on flooring and furniture.

Triple Insulated Glass uses three panes with two air spaces. It increases insulation and sound control versus double pane units. It is used in cold regions or rooms facing traffic where noise is a concern.

Double Tempered Glass focuses on safety. When broken, the glass forms small granules to reduce injury risk. It is widely used in high-rise projects. For energy goals, this option can be paired with Low-E to balance safety and thermal performance.

Custom Style Options for N2 Series Narrow Casement Window

Large fixed glass designs use a wide fixed center panel with operable sashes on both sides. One fixed panel can reach 8 m². This layout reduces frame coverage and increases daylight. It supports clear views for gardens, lakes, or city skylines. Two side openings can create airflow across the room.

Special shape designs move beyond a standard rectangle. Options include an octagon or diamond top, a hexagon or pitched-roof top, and an arched top. These shapes help match specific facade lines. An arch or peak can also change how room height feels.

Multi-panel grid designs use horizontal or vertical mullions to split the window into zones. More frame support helps improve wind load capacity, which can suit high floors or windy sites. A fixed lower lite can act as a barrier for homes with children. Operable sash width can be set within 510–850 mm to support handling and daily use.

Standard vertical designs focus on simple lines and clear symmetry, or a single-sided layout. Common forms include an L-shaped asymmetric layout, a single sash, or a double casement. This option supports tilt-and-turn operation and keeps maintenance scope clear.
