The 3 x 3 casement window is an engineered outward-opening aluminum window built for B2B buyers needing custom-sized, energy-efficient fenestration for residential and commercial projects.
- Thermal-break 6063-T5 aluminum frame with PA66 insulation strip
- 5+27A+5 mm double tempered insulated glass with argon gas
- WEHAG hardware with two-point or six-point locking system
- Configurable color, glass, and sash layout options from low MOQ
Product Details
The 3 x 3 casement window relies on a thermal-break 6063-T5 aluminum frame—available in 109, 118, or 127 mm depths—paired with a PA66 insulation strip. This structure interrupts thermal transfer far more effectively than non-thermal-break profiles, reducing heating and cooling loads. The base 5+27A+5 mm double tempered insulated glass uses argon gas and a PVDF aluminum spacer to support consistent indoor comfort.
The 36 x 36 in (914 x 914 mm) nominal size fits standard residential and commercial openings. Buyers can adapt the glazing to specific climate or security demands using Low-E, laminated, triple, tinted, reflective, frosted, or bullet-proof upgrades. Configurable sash layouts—including single, double, and side-opening with center fixed panels—provide design flexibility for varied architectural requirements.
Product Features
Thermal-Break Aluminum Frame: The PA66 strip within the 6063-T5 profile minimizes thermal transfer, directly lowering HVAC loads and supporting energy-efficient building envelope requirements.
Double Tempered Insulated Glass: The 5+27A+5 mm argon-filled unit reduces heat exchange and helps dampen external noise, improving acoustic and thermal comfort for occupants.
WEHAG Hardware Integration: Equipped with a WEHAG handle and hinge, the system uses a two-point or six-point lock to pull the sash tightly against weather seals.
Outward Opening Mode: Hinges on the exterior allow the sash to swing outward, saving valuable interior floor space and facilitating unobstructed side ventilation.
Configurable Glass Upgrades: Buyers can specify Low-E, laminated, or triple glazing to match project-specific climate, acoustic, or security demands.
PVDF Aluminum Spacer: The standard PVDF spacer maintains edge sealing integrity, with an optional warm-edge upgrade available to further mitigate condensation risks.
Customizable Styles
Glass Configuration: Base 5+27A+5 mm double tempered insulated with argon; upgrades include Low-E, laminated, triple, tinted, reflective, frosted, and bullet-proof options.
Frame Size: Nominal 36x36 in with custom dimensions available; outward sash range spans W350-750 mm x H400-1600 mm for standard systems.
Color Finish: Options include Pearl White, Quartz Gray, Starry Sky Black, and Black Walnut wood grain; fluorocarbon and custom coatings carry upcharges.
Sash Layout: Configurations include single sash, double sash, side-opening with center fixed, three-section, and upper/lower fixed combinations.
Screen Options: Buyers can select anti-theft mesh, 304 high-definition mesh, diamond mesh, or 48-mesh high-transparency screens for insect protection and security.
Hardware Accessories
WEHAG Handle: Available in black or silver finish, offering ergonomic operation with a corrosion-resistant coating for long-term functional reliability.
WEHAG Hinge: Engineered for smooth outward swing, with load-bearing capacity matched to the specific weight and dimensions of the sash.
Multi-Point Lock: Two-point or six-point locking mechanism (by series) enhances security and compresses perimeter seals against air infiltration.
Casement Limiter: Optional simple or safety limiters control the opening angle, supporting child-safety compliance and managing wind exposure.
Safety Fence and Screens: Optional fixed or opening safety fences integrate with multiple mesh types for fall prevention and insect control.

FAQ
How do I request a quote for the 3 x 3 casement window?
Provide size, color, glass configuration, hardware choice, screen selection, project location, and local wind-load code. DERCHI will confirm the series, layout, and current pricing.
What is the MOQ and can I customize size and color?
Reference MOQ is 2 m2 with color and size customization available from that threshold. Buyers should confirm current MOQ and specific customization upcharges during the quote process.
Are the performance parameters guaranteed?
Listed performance values are target specs. Actual performance must be confirmed by final series selection, glass package, and applicable test report verification before ordering.
What is the lead time?
Indicative lead time is 25-35 days depending on order volume and series. Buyers should confirm exact production and shipping schedules during the quotation process.
What certifications apply?
DERCHI holds NFRC, CE, AS2047, CSA, and ISO9001 at the brand level. Buyers must confirm applicability for the specific product series and target market before ordering.
How is the product packaged for export?
Windows use wooden-frame packaging, protective tape, pallet fixing, plastic belts, PE films against sea water, and air bags between pallets to ensure safe international shipping.
Can the 3x3 size be a single sash or does it need split panels?
Engineering confirmation is required. A split operable and fixed layout may be recommended depending on the selected series, sash weight, and project wind-load requirements.
