These opening options allow users to select the ideal mechanism for their aluminum casement windows based on space availability, ventilation preferences, and accessibility needs.

Edge Frame Customization

DERCHI S9 Series aluminum casement windows provide two edge frame packages for different installation requirements. As an aluminum casement window manufacturer, we offer custom casement windows with specialized frame configurations that ensure proper sealing and integration with various wall types.

Available Edge Frame Options:

> New 48 Pack: Standard frame depth of 48mm suitable for regular wall installations and retrofit projects

> New 88 Pack: Extended frame depth of 88mm designed for thicker walls and enhanced thermal performance

These edge frame packages for aluminum casement windows allow installers to select appropriate configurations based on wall construction, climate conditions, and energy efficiency requirements while ensuring compatibility with all casement window hardware.

Style Customization

DERCHI S9 Series aluminum casement windows offer diverse style configurations to meet various architectural requirements. Our custom casement windows include single casement for compact spaces, double casement for wider ventilation, and combinations with fixed panes for larger openings. As a leading aluminum casement window manufacturer, we provide multi-panel configurations mixing fixed and operable units, asymmetric layouts with different pane sizes, and geometric shapes including rectangular and trapezoidal designs. Additional options include picture window combinations with flanking casements and stacked designs with horizontal divisions. All styles integrate seamlessly with casement window hardware for smooth operation and lasting performance.

Glass System

 Double-pane configuration (5mm+27A+5mm) creates superior sound barriers. The 27mm air gap blocks noise transmission effectively.

 Inert gas filling prevents condensation between panes. This technology eliminates fogging and maintains clear visibility year-round.

 Fluorocarbon-treated spacer bars resist discoloration. The coating prevents yellowing and maintains aesthetic appeal over decades.

 DERCHI logo on spacer bars ensures authenticity. Each window features clear brand identification for quality assurance.

Connection Technology

 Foulow-guided injection corner connectors join frames precisely. This system connects outer frames, mullions, and sashes with perfect alignment.

 Two-component corner adhesive strengthens joints permanently. The injection process creates watertight seals and increases structural integrity.

Casement Window Hardware

 Base-free child safety handles prevent accidents. The custom design inhibits bacterial growth and ensures safe operation.

 Heavy-duty hinges support 50kg per sash. These custom components guarantee smooth operation under maximum loads.

 Anti-skew transmission boxes maintain proper alignment. The mechanism prevents diagonal pulling and reduces failure rates significantly.

 Two-point locking system enhances security. Roller lock points and anti-pry bases protect against forced entry attempts.

 Water-swelling EPDM weatherstrips expand 300% when wet. This feature provides exceptional protection in coastal and typhoon-prone regions.

Structural Design

 Anti-collision corner protectors on screen frames increase safety. These components prevent injuries during daily use.

 Patented built-in mesh pressure line improves security. The concealed design prevents tampering while maintaining clean aesthetics.

 Flat interior screen frame eliminates protrusions. This design creates seamless integration with interior spaces.

Flush Frame Design

Frame and sash align on the same horizontal line for both interior and exterior surfaces. Creates seamless appearance while ensuring proper weather sealing and structural integrity.

Advanced Profile System

1.8mm multi-cavity aluminum profile incorporates multiple sealing layers to block noise transmission. Three-seal structure provides enhanced weather protection and thermal performance for residential applications.

Superior Insulation Strip

44mm extra-wide insulation strip effectively reduces the U-value of the complete window assembly. Provides thermal insulation and noise reduction for improved indoor comfort and energy efficiency.

Micro-Elastic Glass Protection

Micro-elastic glass blocks prevent direct contact between glass panels and aluminum profiles. Overcomes structural weaknesses at toughened glass corners while maintaining long-term window performance and durability.
