These 72 inch casement windows are made-to-size thermal-break aluminum systems from DERCHI, built for project buyers needing specific width configurations. The S9 Starlight System serves as the primary recommendation, with R8Y and E6N alternatives available for coastal or internal-opening demands.
- Width-segment custom manufacturing (72 inches / approx. 1829mm)
- Multi-series selection (S9, R8Y, E6N) for different project environments
- Thermal-break aluminum with 44mm extra-wide insulation strip
- Configurable glass, structure, and hardware options
Product Details
The S9 Starlight System anchors this offering with a 109mm frame width, 1.8mm wall thickness, and a 44/24/15mm multi-insulation strip configuration. Standard glass is 5+27A+5 fluorocarbon insulating aluminum spacer glass. It supports outward opening, top-hung, and outward-opening top-hung configurations, with the glass sash opening outward and the screen sash opening inward. Structural technology includes a multi-cavity aluminum profile, a three-seal structure, and a micro-elastic glass block that reduces corner stress.
For projects requiring different performance priorities, the R8Y series offers a 118mm frame with anti-fall rope and equal-pressure drainage for coastal environments, while the E6N series features a 103mm frame with internal tilt-and-turn operation for residential applications. Because this is a width-segment product, the 72-inch opening is typically split into double-sash, three-sash, or fixed center with side opening configurations to manage glass weight and ventilation needs.
Product Features
- Thermal Break Technology: The 44mm extra-wide insulation strip and multi-cavity aluminum profile work together to reduce U-value, supporting energy efficiency in climate-controlled environments.
- Three-Seal Weatherproofing: EPDM water-swelling weatherstrip combined with a three-seal structure helps manage water and air infiltration during heavy rain and strong wind conditions.
- Stress-Relief Glass Block: A micro-elastic glass block reduces stress at glass corners, which is particularly relevant for large fixed panes or multi-sash combinations at this width.
- Safety Hardware Suite: Includes a child-safe handle, anti-pull diagonal transmission box, two-point lock, roller-sleeve lock point, and anti-pry lock seat for secured operation.
- Multi-Series Adaptability: Buyers can select S9 for general outward opening, R8Y for coastal safety features, or E6N for internal tilt-and-turn ventilation based on project requirements.
- Manual-Verified Performance: S9 manual lists 35dB sound insulation, 700Pa water tightness, and 5kPa wind pressure resistance; buyers should confirm test report applicability for their configuration.
