Glass Customization Options
Our E0 Soundproof Double Glazing Casement Windows are available with several glass options. These choices affect window performance in areas like safety, energy efficiency, and light transmission. Select a glass type to meet specific project requirements.
> Low-E Glass: This glass has a coating to reduce heat transfer. It helps keep interiors warmer in winter and cooler in summer.
> Tempered Glass: This is a type of safety glass. It is processed for strength and shatters into small, blunt pieces if broken.
> Laminated Glass: This safety glass holds together when shattered. An interlayer keeps the glass layers bonded, increasing security.
> Reflective Glass: This glass has a metallic coating to reflect heat and light. It reduces glare and solar gain from the outside.
> Tinted Glass: This glass is colored to absorb solar energy. It reduces heat and glare inside the building.
> Insulated Double Glass: Two panes of glass are separated by a sealed air or gas space. This improves sound and thermal insulation.
> Insulated Triple Glass: Three panes of glass with two sealed spaces offer enhanced insulation. This further reduces noise and heat transfer.
> Bullet-proof Glass: Multiple layers of glass and plastic provide ballistic resistance. This glass is for high-security applications.

Design & Style Options
The E0 casement window series is built on a modular system. This framework allows for extensive style customization using standardized components. It supports both common and unique architectural designs.
> Standard Rectangular Windows: Available in single, double, or multi-pane layouts. These styles are suitable for typical residential and commercial facades, maximizing light and view.
> Custom Geometric Shapes: Includes configurations like sloped top, stepped, and hexagonal windows. These options fit special structures such as attics, split-levels, or feature corners.
> Fixed & Operable Sashes: Configurations can combine fixed (non-opening) panes with operable sashes. Opening methods include side-hung (casement) or top-hung (awning) to meet ventilation needs.
> Scalable Dimensions: Window widths are adjustable. The system allows for custom sizing to fit specific project openings while maintaining structural and weather-sealing performance.
> Curtain Wall Integration: The window frames feature a uniform depth. This design enables straightforward integration with standard curtain wall systems and building envelopes.
> Smart System Ready: Frames are designed to accommodate future technology. They include provisions for electric openers and sensors, allowing for upgrades to smart automation.

What is the DERCHI E0 Casement Window?
This is the E0 Soundproof Double Glazing Casement Window from DERCHI. It is a casement window, hinged on one side to open outward. A crank handle operates the window.
The E0 window features a thermal break aluminum frame and double glazing. This construction provides sound insulation. The double glazing also contributes to energy efficiency by creating a seal when the window is closed. This design offers a clear, unobstructed view.
DERCHI offers this product for wholesale. These are aluminum thermal break casement windows. As soundproof casement windows, they reduce noise transmission. The use of double glazing makes them casement window double glazing products. These are available as double casement windows.
Key Features of the E0 Soundproof Casement Window
The E0 soundproof casement window features an aluminum thermal break frame and double glazing for superior insulation and security. A durable, high-performance solution available for wholesale.

Glass:
> Thick Dual Panes: Features two 5mm glass panes separated by a 27mm air gap for superior sound insulation.
> Inert Gas Filling: The space between panes is filled with inert gas. This improves sound and heat insulation while preventing internal fogging.
> Durable Aluminum Spacer: The aluminum spacer has a fluorocarbon finish. This treatment prevents discoloration over time.
> Brand Identification: The DERCHI logo is printed on the aluminum spacer for clear brand recognition.
Frame Construction:
> Precise Corner Joints: The frame uses new-type injection-molded corner codes. This method creates flatter, more precise connections efficiently.
> Enhanced Corner Strength: Two-component corner glue is injected into the joints. This process increases water resistance and strengthens the corners.


Hardware:
> Custom Safety Handle: The custom handle has a simple, base-less design. It incorporates child safety features and inhibits bacterial growth.
> Heavy-Duty Hinges: Custom hinges support a single sash weight of up to 50KG, ensuring durability.
> Anti-Skew Mechanism: The transmission box prevents the sash from skewing. This ensures smooth operation and reduces failure rates.
> Secure Locking System: A custom two-point lock with roller locking points and an anti-pry seat enhances window security.
> Weather-Sealing Strips: The outdoor EPDM strip expands up to three times its size when wet. This seals the window against rainwater, ideal for coastal areas.
Structural Design:
> Screen Safety Corners: The screen sash includes anti-collision corners. This design feature improves user safety.
> Secure Screen Pressing Line: A patented built-in pressure line secures the diamond mesh screen, increasing anti-pry security and aesthetics.
> Flat Screen Frame: The interior screen sash features a flat frame design. This creates a clean, seamless look with no protruding profiles.

Performance Specifications
Explore the certified performance ratings of the E0 casement window. These metrics demonstrate the window's capability to withstand extreme weather, insulate against noise and temperature, and ensure long-term durability and structural integrity.
Thermal insulation
A thermal transmittance value of 1.8 watts per square meter-kelvin results in a grade 7 thermal insulation rating. The thermal break in the aluminum frame and the insulated glass unit reduce heat flow. This helps maintain a consistent indoor temperature and lowers energy consumption for heating and cooling.
Wind pressure resistance
Engineered to resist wind pressures up to 5 kilopascals, the E0 window achieves the highest performance grade of 9. The robust frame and secure locking mechanisms ensure the window's structural integrity in high-wind events. This makes it suitable for high-rise buildings and exposed locations.
Waterproofing
The E0 window withstands water penetration under pressures of 700 pascals. This performance, rated at grade 6, ensures the interior remains dry even during severe weather conditions. The system's design effectively channels water away from the structure.
Air tightness
With an air leakage rate of only 1.2 cubic meters per meter per hour, this window achieves a grade 8 rating for air tightness. This feature minimizes drafts and prevents conditioned air from escaping. It contributes to a stable indoor climate and energy efficiency.
Sound insulation
The window provides a sound reduction of 35 decibels, earning a grade 4 in sound insulation. The double-glazing system, featuring two panes of glass separated by a sealed air gap, effectively dampens exterior noise. This creates a quieter interior environment, suitable for urban or noisy areas.
