Key Advantages for Importers, Builders & Developers
Our aluminum sliding window systems are tailored to solve common structural and thermal challenges faced in high-end construction projects.
Slim Sightlines & Panoramic Views
Engineered with slender frame profiles and narrow interlocking stiles to maximize daylight transmittance and deliver expansive, unobstructed outdoor views.
Energy Efficiency & Climate Control
Advanced polyamide thermal break structures prevent thermal transfer, lowering heating and air conditioning loads to meet modern building energy codes.
Weather Tightness & Wind Resistance
Designed with stepped drainage channels, concealed weep holes, and continuous EPDM gaskets to prevent water infiltration under storm pressure.
Multi-Point Anti-Theft Security
Integrated multi-point locking rods and anti-lift blocks prevent sashes from being forced open or removed from the outer frame from the exterior.
Precision CNC Manufacturing
Produced on automated CNC cutting and corner-crimping assembly lines at our 115,000 m² factory, ensuring perfect dimension tolerances for rapid site installation.
Tested & Certified Quality
Full compliance with international standards including ISO 9001 quality management, AS2047 Australian testing, European CE, and NFRC energy ratings.
Sliding Window Track & Sash Configurations
Foshan Derka Architectural Doors & Windows Co., Ltd. provides flexible window framing configurations tailored to your architectural floor plan.
2-Track Sliding Windows
Classic dual-sash design where one or both panels slide horizontally. Ideal for bedroom openings, living spaces, and standard wall cavities.

- 100% operation smoothness check for rollers & locks
- Water spraying and airtight chamber testing
- Project-specific crate labeling with opening marks for installers
Frequently Asked Questions About Aluminum Sliding Windows
Detailed answers for contractors, developers, and trade buyers importing windows from China.
Our aluminum sliding windows deliver exceptional space savings, expansive panoramic views, robust weatherproofing, and superior thermal insulation. Utilizing 6063-T5 high-density aluminum extrusions and polyamide PA66 thermal barriers, they achieve outstanding acoustic reduction and energy efficiency compliant with global standards.
Yes. Every sliding window configuration can be customized with specific thermal breaks, double or triple Low-E argon-filled glazing, and reinforced mullions to meet North American NFRC/Energy Star ratings, Australian AS2047 specifications, and European CE standards. Official test certificates are provided prior to shipment.
We offer complete made-to-measure flexibility including 2-track, 3-track (with integrated flyscreens), and 4-track multi-slide profiles, heavy-duty lift-and-slide mechanisms, custom powder coating (RAL colors), anodized finishes, fluorocarbon (PVDF) spray, and custom glass specifications.
Each order undergoes a strict 44-point quality inspection process covering profile wall thickness verification, CNC cutting accuracy, corner joint strength, seal continuity, hardware operating smoothness, and airtightness/watertightness testing prior to export-grade protective crating.
