Thermal Break Single-Hung Window
Engineered with a 70mm frame depth and 24mm PA66 polyamide insulation strip. Built for mid-to-high-rise residential projects requiring high structural integrity and sleek sightlines.
Get CatalogIn modern commercial architecture and high-density residential developments, Single-Hung Aluminum Windows stand out as the definitive fenestration choice. Combining classic vertical ventilation aesthetics with rigid structural frames, single-hung systems feature a stationary top sash and a vertically operable bottom sash. At Crestor Door Manufacturing Co., Ltd., we transform this classic window configuration into an ultra-efficient, thermal break system designed to meet strict NFRC, CE, and AS 2047 energy codes.
Engineered at our Beijing R&D center and produced across our 100,000 m² smart factory in Dongying, Shandong, our single-hung aluminum windows incorporate 6063-T5/T6 extrusions, laser cold-welded corner joints, PA66 polyamide thermal barriers, and heavy-duty spiral/constant-force balance mechanisms. Whether you are an architectural specifier, commercial contractor, or window brand owner looking for dependable OEM/ODM supply, Crestor delivers certified structural strength and thermal insulation directly from our production lines.
Tailored for high-rise residential, hospitality, institutional, and commercial facades, our single-hung systems deliver optimized U-factors, maximum wind resistance, and smooth vertical movement.

As energy efficiency mandates tighten globally, single-hung aluminum window design is experiencing rapid technological elevation. Key developments led by Crestor include:
Traditional single-hung aluminum frames suffered from thermal bridging. Crestor integrates multi-chambered PA66 GF25 polyamide insulation strips within 6063-T5 aluminum extrusions, isolating external temperatures from interior spaces and eliminating condensation.
Mechanical corner brackets are upgraded with laser cold-welding jointing combined with two-component glue injection. This creates a structurally unified frame joint with zero corner gap, offering unmatched weather resistance and preventing frame distortion under heavy wind pressure.
Modern single-hung sashes frequently specify heavy double- or triple-glazed Low-E units. Crestor incorporates heavy-duty constant-force spring balances and stainless steel spiral balances that calibrate lifting resistance precisely to sash weight, eliminating sash drop and reducing operational force.
Security is paramount in modern fenestration. Crestor sashes utilize heavy-duty cam-action sweep locks and interlocking meeting rails with continuous EPDM bulb seals, preventing forced entry and air leakage across meeting rail seams.
Understanding shifting buyer preferences and market dynamics enables developers and importers to optimize their procurement strategies.
A window is only as strong as its weakest component. Every profile, gasket, and balance spring is manufactured and assembled under one roof.

High-tensile virgin aluminum extrusions with PA66 thermal barriers.

CNC-machined frame sashes featuring tight tolerance corner joints.

Double & triple glass options filled with 90%+ Argon gas fill.

Continuous weatherstripping eliminating air drafts & water ingress.

Precision-calibrated spring balances for effortless sash operation.

High-clarity insect and security screen options.
Combining nearly 30 years of manufacturing experience with direct-from-factory pricing and certified engineering.

From aluminum extrusion machining and powder coating to insulating glass production and final sash assembly, everything is managed inside our own plant. No sub-contracting risk, full quality control.

Our dedicated R&D team in Beijing analyzes project wind loads, thermal specs, and structural building codes to produce custom shop drawings and tailored window profiles for global clients.

Tested to China's national standards and international fenestration codes, our windows hold AS 2047 StandardsMark License SMK41686, ISO 9001:2015 certification, and CE conformity.

Eliminates traditional visible frame joints and corner gaps. Laser cold-welding produces seamless corner strength, superior air tightness, and exceptional aesthetic finishing.

We work with global window brands, wholesalers, and developers to supply custom frame profiles, custom powder coating colors, hardware branding, and private protective packaging.
