Precision-Engineered Thermal Break Casement Windows
Primor Metal Door Co., Ltd. custom manufactures industrial-grade thermal break aluminum casement windows tailored for commercial developments, residential villas, and architectural distribution partners globally.
High Performance & Engineering Standards
Casement windows provide the highest air tightness, water tightness, and structural stability among all operable window styles. By utilizing side-hinged sashes that seal firmly against multi-channel EPDM rubber gaskets under lever compression, our Series 119 and Series 80 casement windows deliver outstanding thermal performance for extreme climate zones.
Every profile is constructed from high-tensile 6063-T5 aluminum extrusions combined with low-conductivity PA66GF25 polyamide thermal break strips. This design significantly reduces thermal bridging, prevents indoor condensation, and enhances HVAC energy savings in compliance with international energy codes.

Flexible Casement Configurations for B2B Projects
To support diverse architectural schedules, Primor Metal Door Co., Ltd. offers full OEM/ODM flexibility across custom dimensions, sash directions, and combined fixed-and-operable lite layouts.
Outswing Casement Windows
Engineered with friction stays or cranking operators. Ideal for rainy and windy regions as exterior wind pressure pushes the sash tighter against seals.
Inswing & Tilt-Turn Windows
Dual-function European hardware allowing inward swing for complete ventilation and top-tilt for draft-free security venting and easy interior cleaning.
French Double-Sash Windows
Double casement sashes opening from the center without a vertical mullion, creating an unobstructed wide opening for views and emergency egress.
Integrated Insect Screens
Optional stainless steel security mesh, high-transparency fiberglass screens, or motorized retractable screens integrated directly into the window frame.
Surface Finishes & Quality Control
We apply high-durability surface coatings certified to Qualicoat and AAMA standards, ensuring long-term resistance against UV radiation, salt-spray oxidation, and surface abrasion:
- Powder Coating: Available in RAL custom colors, matte black, architectural bronze, and pure white.
- PVDF Fluorocarbon: Exceptional weatherability for severe coastal and tropical environments.
- Anodized Finishes: Champagne, silver, satin bronze, and metallic black anodizing.
- Thermal Transfer Wood Grain: Authentic timber appearance combined with aluminum durability.
Prior to packing, every unit undergoes strict quality control inspection—including sash alignment checks, seal compression verification, water spraying testing, and protective film wrapping.
Frequently Asked Questions for Importers & Contractors
Q: Can you manufacture casement windows according to our CAD shop drawings?
Yes. Our engineering team reviews architectural drawings, structural wind-load requirements, and window schedules, issuing finalized CAD shop drawings for sign-off prior to production.
Q: How are products packed for containerized overseas shipment?
Windows are labeled according to project opening numbers, wrapped in protective foam film, corner-protected, and packed into fully enclosed export plywood crates suitable for FCL and LCL ocean transport.
Q: What is the typical production lead time for bulk orders?
Standard lead time is 25-35 days following drawing approval and deposit receipt, depending on profile finishes and glass specifications.
