Inward Opening Windows

Selective Color Options

The DERCHI WN-112 Series features a distinct color palette tailored for versatility. This selection divides into two primary categories: PVDF and Stock Color. Each category offers specific benefits for different design requirements.

PVDF coatings provide superior weather resistance. This finish suits exteriors exposed to harsh sunlight. Retro Green offers a dark, matte appearance. Mint Gold presents a metallic tone similar to champagne. These options ensure durability without compromising style.

The Stock Color category includes ten varied options. For a natural look, Huanghua Pear and Black Walnut mimic wood grain patterns. These fit well with traditional or retro interiors. Classic solid tones include Pearl White, Deep Coffee, and the warmer Caramel Coffee.

Modern designs often require unique textures. Black Skin provides a smooth, matte surface. Black Crystal Stone adds a granular look, while Starry Sky Black features subtle details. Quartz Gray resembles stone, and Deep Sea Blue adds a cool, grey-blue hue. Choose the finish that best matches your architectural environment.

Operation Modes

The WN-112 Series features a dual-action hardware system. This design allows the window to operate in two distinct ways depending on ventilation and maintenance needs.

The Tilt and Turn mode tilts the top of the sash inward while the bottom remains fixed. This creates a small opening for airflow. Air enters from the top, which prevents direct drafts on people inside. The inclined angle allows water to run off, keeping the interior dry even during rain. This position also enhances safety. The small gap prevents intruders from entering and stops children from climbing out.

The Inward Opening mode swings the sash fully into the room on side hinges. This motion resembles a standard door. It opens the entire window area for maximum ventilation. This mode is essential for rapid air exchange. It also simplifies maintenance. You can clean the exterior glass surface while standing inside the room. This eliminates the danger of high-altitude cleaning. In emergencies, this full opening serves as an effective escape route.

Glass Configurations

The WN-112 Series offers eight distinct glass specifications tailored for efficiency, safety, and aesthetics.

Energy Efficiency: Three options focus on thermal regulation. Low-E Glass features a metallic coating that acts as a thermal mirror. It reflects heat back inside during winter and blocks external heat in summer. Insulated Double Glass separates two panes with an air gap to stop heat transfer. Insulated Triple Glass adds a second air chamber. This configuration provides maximum insulation for extreme climates and reduces noise.

Safety and Strength: Structural options prioritize security. Tempered Glass undergoes heat treatment to increase strength. If it breaks, it crumbles into blunt granules to prevent injury. Laminated Glass: bonds two panes with a PVB layer. This holds fragments in place upon impact and dampens high-frequency noise. Bullet-proof Glass uses a multi-layer composite structure. It withstands ballistic threats and forced entry.

Aesthetics and Privacy: Visual treatments manage light and privacy. Reflective Glass creates a mirror effect on the exterior. It blocks views from the outside during the day and reflects intense sunlight. Tinted Glass absorbs solar radiation to reduce glare.

Selection Advice: Choose Laminated or Insulated Triple Glass for noisy environments. For standard thermal performance, combine Low-E with Insulated Double Glass. Rooms with heavy sun exposure benefit from Reflective or Tinted options.

Customizable Styles

The WN-112 Series offers a flexible system to match specific architectural designs. This range adapts to diverse structural requirements through four primary configurations.

Combination Windows pair fixed glass with opening sashes. The fixed panels provide unobstructed views and reduce costs. The opening sections ensure necessary airflow. Popular layouts include a large central fixed pane flanked by side openers or asymmetric split designs.

Special Shapes accommodate unique building aesthetics. Hexagon or diamond shapes fit well in attics and stairwells. Arched tops add elegance to French or Mediterranean styles. For maximum ventilation, Double Sash models feature two opening panels.

Bay and Corner Windows project outward from the wall. This structure increases interior space and allows light to enter from three sides. These designs appear as distinct polygonal shapes in floor plans.

Design Recommendations For living rooms, select a "Picture Frame" combination with a large fixed center. This maximizes the view. Bedrooms benefit from standard square windows with tilt functions for privacy. For villas or top floors, arched or geometric shapes enhance the building's exterior appearance.
