High-Performance Replacement Systems for Global Procurement
Window and door replacement requires more than simple profile swapping. It demands exact structural matching, thermal barrier continuity, water tightness engineering, and long-term durability under harsh climate exposure.
Royal Windoor US manufactures architectural-grade replacement window and door assemblies engineered for seamless retrofit into existing building envelopes. Whether upgrading aging commercial fenestration, replacing low-efficiency builder vinyl, or supplying multi-family retrofit projects worldwide, our systems deliver superior thermal insulation, sound dampening, and air-tight seals.
Our direct-to-site and containerized wholesale shipping model eliminates distributor markups, supplying contractors, commercial glaziers, property developers, and international importers with customized solutions built directly to architectural drawings.

Precision Fabrication & Quality Control Workflow
Every replacement system undergoes rigorous quality audits at every stage of production, ensuring exact dimension accuracy and zero-defect delivery.
CAD & Opening Analysis
Review of structural opening tolerances, wind load dynamics, thermal targets, and fenestration CAD drawings to ensure complete alignment with project requirements.
Precision CNC Fabrication
Automated cutting, corner crimping, and notch milling executed via multi-axis CNC machinery with tolerance precision within ±0.5 mm across all frame profiles.
Insulated Glass Assembly
Automated double/triple glass washing, warm-edge spacer application, inert gas filling, and dual-seal structural silicone bonding in a clean-room environment.
German Hardware Fitting
Installation of multi-point locking gear, stainless steel hinges, and concealed drainage pathways configured specifically for high-frequency operational cycles.
AAMA Air/Water Testing
Batch sampling tested in mock-up chambers under simulated positive/negative pressure, torrential rain injection, and operational cycle endurance runs.
Export Packaging & Crating
Corner protectors, protective foil wrapping, vacuum moisture control, and fully enclosed steel-reinforced wooden crating for ocean FCL/LCL transit.
Tested, Certified, and Compliant for International Deployment
We adhere strictly to international building envelope codes and structural integrity standards, giving commercial architects and procurement teams complete peace of mind.
ISO 9001 Quality System
Certified factory management protocol covering raw material verification, extrusion alloy inspection, and finished product quality control.
NFRC & AAMA Standards
Tested for solar heat gain coefficient (SHGC), U-factor thermal conductivity, optical clarity, and structural resistance under extreme wind pressure.
Severe Windstorm Compliance
Structural impact testing conforming to ASTM E1886/E1996 large missile impact criteria for hurricane and cyclone coastal zones.
CE & AS2047 Conformance
Compliance documentation certified for European Union and Australasian commercial building fenestration requirements.
Heavy-Duty Packaging & Ocean Freight Consolidation
Transporting fragile architectural glass and heavy extruded metal frames across international trade routes requires standardized export packaging protocols engineered to prevent transit damage.

- Complete Export Documentation: Bill of Lading, Commercial Invoice, Packing List, Certificate of Origin, and Factory Inspection Reports provided with every order.
Frequent Questions From Procurement Officers & Importers
For standard architectural profiles, our minimum production batch is 20 units or 50 square meters. For commercial developments and wholesale FCL orders, volume tiered pricing applies. Sample units can be produced for technical validation prior to bulk manufacturing.
Every batch follows strict ISO 9001 quality protocols. Extrusion dimensions are validated by laser micrometers, hardware alignment is verified on assembly jigs, and glass seals are tested for dew-point and vacuum integrity before packaging.
Yes. We manufacture strictly according to client-provided shop drawings, laser measures, or CAD schedules. Our CNC machining process ensures dimensional tolerances within ±0.5 mm for precise field fitting without structural framing alterations.
Typical manufacturing lead times range from 3 to 5 weeks for uPVC vinyl and standard aluminum lines, and 4 to 6 weeks for custom thermally broken or hurricane impact systems. Ocean shipping time depends on destination ports and container schedules.
We provide a written 10-year manufacturer warranty on aluminum frames and surface finishes, a 10-year warranty on insulated glass unit seals, and a 5-year warranty on German multi-point locking hardware mechanisms. Replacement components are stocked for rapid global dispatch.
