The 18 x 48 casement window is a hand-crank operated aluminum unit built for versatile placement in residential and commercial projects. It features a 6063-T5 aluminum frame, EPDM sealing, and double tempered glass, suiting contractors and specifiers sourcing reliable fenestration.
- Nominal size 18 x 48 in (457 x 1219 mm) with hand-crank flat-opening operation
- Three frame depth options: 72 mm, 86 mm, or 100 mm for varied structural needs
- Configurable glass packages, color finishes, and hardware accessories
Product Details
Structurally, this crank-out window utilizes a 6063-T5 aluminum profile at 1.4 mm thickness. Buyers can select from three frame depths—72 mm, 86 mm, or 100 mm—matching the WY-72, WY-86, and WY-100 series. Sealing is handled by EPDM rubber strips, while the double tempered glass varies by series (5+27A+5 mm or 5+15A+5 mm). Operation is via a hand-crank mechanism for flat opening or hanging up.
Unlike standard fixed units, this aluminum casement window offers extensive project flexibility. The three series options allow buyers to align frame depth and glass packages with specific performance targets. Customizable layouts include single sash, awning, and fixed-plus-operable composites. An expansive option list covers limiters, safety fences, glass upgrades, and PVDF finishes, all packaged in wooden frames with PE films for sea freight.
Product Features
Hand-Crank Operation: Enables ventilation control in hard-to-reach positions without needing direct access to the sash, offering convenience for above-counter or exterior wall installations.
6063-T5 Aluminum Frame: Corrosion-resistant material suitable for exterior applications and long-term weather exposure, providing structural stability for various building types.
EPDM Rubber Sealing: Contributes to the 350 Pa water resistance and 4.5 m3/(m.h) air leakage performance, helping to reduce drafts and moisture ingress.
Double Tempered Glass: Safety glazing achieving 30 dB sound insulation, available in two spacer configurations depending on the selected series.
Multiple Frame Depths: Options of 72 mm, 86 mm, or 100 mm let buyers match structural cavity dimensions and performance targets to specific project requirements.
Export-Ready Packaging: Wooden-frame packaging with PE films, pallets, and air bags protects units during international sea freight shipping.
Customizable Styles
Glass Configuration: Choose 5+27A+5 mm or 5+15A+5 mm double tempered glass by series, with optional argon, warm-edge, Low-E, triple, or laminated upgrades.
Frame Depth: Select 72 mm, 86 mm, or 100 mm based on wall structure and performance requirements for the specific project.
Size: Made-to-order within the W450-800 mm x H600-1500 mm opening panel range; the 457 x 1219 mm nominal size fits within range.
Color and Finish: Twelve standard color families including Pearl White and Quartz Gray, plus PVDF/fluorocarbon and custom wood grain options.
Style Layout: Options include single sash, double sash, side-opening plus center fixed, three-segment, top/bottom fixed, or irregular combinations.
Hardware Accessories
