The 48 x 42 casement window is a made-to-size thermal-break aluminum system built for residential and commercial projects. DERCHI engineers this opening around 48 x 42 in (1219 x 1067 mm) dimensions, offering configurable sash divisions, glass types, and series selections rather than a stock standard product.
- Primary recommendation: S9 Starlight System with 109mm frame and 44mm extra-wide insulation strip
- Alternative series: E0 Glory for budget/batch projects, S6 Star Sea for lightweight mid-range applications
- Configurable structure: double-sash, three-lite, fixed+opening, and multi-sash combinations
- Outward opening design: glass sash opens outward, screen sash opens inward to save interior space
Product Details
This custom 48 x 42 casement window covers approximately 1.30 square meters. The primary recommended double-sash structure divides the opening into two 24.0 in (610 mm) lites, falling within the 400-750 mm outward casement sash width range. A three-lite configuration yields roughly 16.0 in (406 mm) per lite. The S9 Starlight System carries a 109 mm frame width, 1.8 mm wall thickness, and a 44/24/15 mm multi-thermal-strip arrangement.
Structural differentiation comes from a 1.8 mm multi-cavity aluminum profile, a three-seal structure, and a micro-elastic glass block that reduces corner stress. The frame and sash sit on the same horizontal line for a flush appearance. As a 48 x 42 casement window manufacturer, DERCHI also offers the E0 Glory (100 mm frame, 35/30/12 mm strips) and S6 Star Sea (82 mm frame, 35/14.8/30 mm strips) series, giving buyers three tiers of frame width and thermal strip configuration to match specific project budgets.
Product Features
- Thermal-Break Engineering: The multi-cavity aluminum profile and 44mm extra-wide insulation strip (S9) help reduce U-value and support energy-efficient building requirements.
- Opening Configuration: Glass sashes open outward while screen sashes open inward, preserving interior floor space and allowing unobstructed ventilation control.
- Security Hardware Suite: Includes a child-safe handle, anti-pull oblique transmission box, two-point lock, and anti-pry strike plate to resist forced entry attempts.
- Weather Sealing: A three-seal structure paired with EPDM water-swelling weatherstrip contributes to the verified 700Pa water tightness and Level 8 air tightness ratings.
- Acoustic Insulation: Rated at 35dB sound insulation (Level 4), though buyers should confirm the test glass configuration matches their selected glazing.
- Stress Reduction: The micro-elastic glass block technology minimizes glass corner stress, which is particularly useful for large or multi-lite combination window walls.
Customizable Styles
- Glass Options: Standard 5+27A+5 hollow tempered glass; custom choices include argon gas, Low-E, laminated, frosted, tinted, ultra-clear, and built-in blind glazing.
- Color and Finish: Available in Sand Gray, Dark Coffee, Black Crystal, White, Black Walnut, Fluorocarbon Flash Silver, and more; finishes include powder coating, fluorocarbon, and wood grain.
- Frame and Series: Choose S9 (109mm high-end), E0 (100mm budget), or S6 (82mm lightweight) thermal-break aluminum profiles based on project performance and cost requirements.
- Size and Structure: Configure as single sash, double sash, fixed+opening, three-segment, asymmetric, or multi-lite window wall combinations to fit specific openings.
- Opening Style: Supports outward opening, top-hung, and outward-opening top-hung configurations; optional 48-mesh screen, stainless steel mesh, or guardrail available.
Hardware Accessories
- Handle: DERCHI custom child-safe handle standard on S9; S6 uses a WEHAG baseless handle; optional fingerprint/password/key handle available.
- Hinge: 13-inch casement friction hinge controls outward opening speed and hold angle, preventing wind-slam damage to the sash.
- Lock System: Two-point lock with roller-sleeve lock point and anti-pull oblique transmission box secures the sash at multiple contact points.
- Strike Plate: Anti-pry strike plate reinforces the locking mechanism against physical intrusion attempts.
- Sealing Hardware: EPDM water-swelling weatherstrip expands when exposed to moisture, actively improving the seal during rain; buyers needing specific hardware brands should confirm availability.
