Aluminum casement windows with protector from DERCHI combine thermal break engineering with an integrated safety system for high-rise and coastal projects. The R8Y Ruixuan series pairs a 118mm frame, 35mm wide insulation strip, and WEHAG hardware with concrete protector components—anti-fall rope rated at 150KG, anti-theft flyscreen, diamond mesh, and a patent six-point lock.
- Thermal break system with 2.0W/(m²·K) Class 6 insulation and triple sealing
- Protector package: 150KG anti-fall rope, anti-collision corner, diamond mesh, anti-theft flyscreen
- WEHAG antibacterial handle with silver ion coating inhibiting up to 99% of bacterial growth
- Custom glass, color, structure, and opening configurations for project-specific requirements
Product Details
These custom aluminum casement windows with protector use a 118mm thermal break aluminum frame with 1.8mm wall thickness and a 35/34/16mm insulation strip configuration. The glass sash opens outward while the flyscreen sash opens inward, allowing ventilation and insect protection in a single unit. Opening types include outward casement, top-hung, and outward-opening top-hung, with sash dimensions ranging from 350–750mm in width and 450–1500mm in height. Single fixed glass panels can reach up to 12 square meters.
Weather resistance comes from triple sealing with equal-pressure drainage and concealed drainage channels, using EPDM water-swelling weatherstrip. Standard glazing is 5+27A+5 hollow tempered glass with a fluorocarbon hollow aluminum spacer. For projects needing different frame profiles, the Jinghong 100 series (100mm frame) and S9 Xingguang series (109mm frame, 44/24/15mm insulation strip) offer alternative configurations—buyers should confirm which series best matches their performance and dimensional requirements.
Product Features
- Anti-Fall Rope (150KG): The integrated anti-fall rope carries up to 150KG, preventing sash detachment in high-rise outward-opening installations where wind gusts could force the window outward.
- Patent Six-Point Lock: The custom black zinc alloy four-side six-point lock is an invention patent, providing multi-directional locking that resists forced entry and improves sash compression sealing.
- WEHAG Antibacterial Handle: Silver ion coating on the WEHAG baseless handle inhibits up to 99% of bacterial growth, making it suitable for hygiene-conscious environments such as clinics, kitchens, and food-service spaces.
- 35mm Wide Insulation Strip: The super-wide 35mm insulation strip reduces thermal bridging across the frame, supporting a Class 6 thermal insulation rating of 2.0W/(m²·K) for energy-conscious projects.
- Triple Sealing with Concealed Drainage: Equal-pressure drainage channels and EPDM water-swelling weatherstrip work together to manage water ingress, achieving 700Pa water tightness (Class 6) without exposed drainage holes.
- WEHAG Hardware Durability: Germany WEHAG hardware is rated for 100,000+ open cycles, giving project owners long-term operational reliability without frequent component replacement.

- Friction Hinge: 12-inch friction hinge controls sash opening speed and hold position, reducing wind-slam risk on outward-opening sashes in high-rise installations.
- Lock System: Custom black zinc alloy four-side six-point lock (invention patent) provides multi-directional locking; confirm strike plate configuration for project requirements.
- Anti-Fall Rope: Integrated rope with 150KG bearing capacity prevents sash from detaching—confirm rope material and replacement interval for long-term maintenance planning.
- Sealing and Mesh: EPDM water-swelling weatherstrip, built-in diamond mesh glazing bead, and anti-theft flyscreen; confirm mesh material specifications and corner protector details.
