Engineered Thermal Break Casement Window Systems

At Veltor Window & Door Co., Ltd., we engineer high-performance aluminum casement windows tailored for international project developers, general contractors, commercial builders, and window distributors. Operating directly out of Foshan, China, our advanced production facility combines precision 6063-T5/T6 aluminum extrusion profiles with European PA66 polyamide thermal breaks.

Our casement windows deliver outstanding energy ratings, severe weather resistance, and sound attenuation. Every unit is custom-fabricated according to project elevation drawings, wind-load calculations, and local building energy codes.

  • PA66 Polyamide thermal barrier strips
  • Multi-point hardware locking systems
  • Double & triple Low-E insulated glass
  • Factory direct CAD shop drawing support

Opening Modes & Options

Versatile Configurations for Any Building Profile

Whether for modern high-rise apartments, luxury residential villas, or commercial office facades, our casement systems are available in flexible opening styles.

Outward Opening Casement

Traditional side-hung design providing maximum clear open ventilation area without taking up indoor living space. Features friction hinges and multi-point perimeter compression seals.

Inward Tilt & Turn Window

Dual-action European mechanism: turns inward for easy cleaning and maximum ventilation, or tilts inward from the top for secure draft-free background ventilation.

French Double Casement

Twin operable sashes with a floating center mullion, opening up wide unobstructed exterior views for luxury patio and garden access spaces.

Triple Glass Glazing Options

Configurable with double or triple insulated glass units (IGU), Low-E soft coating, warm edge spacers, and argon gas infill for climate-zone energy efficiency.

Integrated Flyscreen Mesh

High-tensile 304/316 stainless steel security mesh or invisible retractable insect screens seamlessly integrated into the thermal break frame profile.

Premium Finish & Hardware

Architectural grade powder coating, PVDF, or anodized finishes in standard RAL colors. Powered by premium hardware including Hoppe, CMECH, and Siegenia.

Factory Assurance

Precision Fabrication & Strict QC Control

From primary 6063-T5 aluminum billet extrusion to automated CNC milling, corner crimping, continuous EPDM gasket sealing, and trial assembly testing, Veltor Window & Door Co., Ltd. maintains strict quality standards.

1. Shop Drawing Confirmation

Our senior structural engineers produce 2D/3D CAD shop drawings detailing profile cross-sections, glass build-up, and wall anchoring for buyer approval prior to production.

2. 100% Pre-Shipment Trial Fit

Every casement window sash is trial-assembled on our test rig to check diagonal squareness, gasket compression seal, friction stay torque, and latch alignment.

3. Export Fumigated Wooden Crating

Windows are wrapped in protective PE film, shielded with rubber corner protectors, and packed into heavy-duty reinforced wooden crates labeled by opening schedule.

Frequently Asked Questions

Casement Window Purchasing Guide

Thermal break aluminum casement windows feature a reinforced polyamide (PA66) insulating strip between the inner and outer aluminum frames. Combined with double or triple Low-E insulated glass units and argon gas filling, this barrier significantly restricts thermal conduction.

Our casement windows are engineered with continuous EPDM multi-seal gasket systems and multi-point compression locks, achieving superior air permeability and high water resistance suitable for severe weather conditions.

Yes. Every casement window unit is custom fabricated according to confirmed shop drawings. We offer architectural powder coating, anodizing, PVDF finishes, and wood-grain sublimation in full RAL color spectrums.

We integrate premium hardware options based on buyer requirements, including top European brands such as Hoppe, Siegenia, CMECH, and Sobinco, ensuring long-term durability and smooth operation.

Each window frame is protected with protective film, foam corner guards, and wrapped in shrink wrap before being loaded into fumigated, reinforced wooden crates labeled by project opening numbers.
