Explore our high-performance thermal break aluminium profiles, steel-look Crittall doors, bi-fold systems, and commercial entrance structures manufactured to European standards.
The architectural landscape of Istanbul presents a unique synthesis of rich historical heritage and cutting-edge contemporary urban development. From the restoration of waterfront yalı mansions along the Bosphorus to high-density commercial towers in Maslak, Levent, and Ataşehir, the demand for ultra-slim, industrial-style glazed openings has reached an unprecedented peak. Traditionally, industrial steel-framed doors—famously referred to as Crittall doors—were favored for their iconic grid aesthetics and razor-thin sightlines. However, legacy steel systems present severe thermal liabilities in coastal and varied climates: thermal bridging, high conductivity, weight-induced hardware stress, and eventual rust under saline atmospheric exposure.
As a leading global manufacturer established in 1993, Window Wurx Industry Co., Ltd. has engineered a modern paradigm shift: CE Certified Aluminium Crittall Door Systems. By replacing heavy steel profiles with high-tensile 6063-T5/T6 extruded aluminium alloys equipped with advanced polyamide thermal break technology (PA66 GF25), our factory delivers authentic industrial aesthetic appeal coupled with world-class energy efficiency, structural rigidity, and zero maintenance overhead.
Information Gain Insight: Modern aluminium Crittall doors eliminate thermal cold-bridging via dual PA66 GF25 structural insulation zones, lowering structural frame weight by 45% while meeting European Union Energy Performance of Buildings Directives (EPBD) and EN 14351-1 CE compliance requirements.
When specifying glazing systems for high-end residential and commercial developments across Turkey and Europe, architectural engineering teams must weigh long-term thermal, structural, and financial parameters:
| Performance Standard / Specification | Traditional Steel Crittall Doors | Window Wurx CE Aluminium Crittall Doors |
|---|---|---|
| Thermal Insulation (Uf Value) | Poor (3.5 – 5.8 W/m²K) - High risk of condensation | Superior (1.1 – 1.6 W/m²K) with PA66 GF25 Thermal Break |
| Corrosion Resistance (Marine Air / Bosphorus) | Prone to rust; requires frequent painting/touch-ups | C5-M Grade PVDF / Qualicoat Powder Coating (Zero Rust) |
| Frame Weight & Structural Load | Heavy (~7.8 g/cm³ steel density); high hinge strain | Lightweight (~2.7 g/cm³ aluminium); smooth operation |
| Sightline Profile Width | Ultra-slim (15mm – 25mm) | Architectural Slimline (18mm – 30mm) matching aesthetic |
| Acoustic Insulation (STC / Rw Rating) | Single glaze limit (25 – 30 dB) | Double/Triple Glazed Acoustic Interlayer (Up to 42 dB) |
| CE Certification & Testing (EN 14351-1) | Limited standardized factory certification | Fully Tested & Certified CE & AS2047 Factory Compliance |
Operating a 20,000 m² automated production plant in Foshan, China with three CNC extrusion & assembly lines, Window Wurx provides direct factory pricing and custom production for Istanbul importers, contractors, and design studios.
Every profile design undergoes rigorous structural load, air permeability (EN 12207 Class 4), and water tightness (EN 12208 Class 9A) testing. Complete technical documentation dossiers and Declarations of Performance (DoP) accompany every export container.
We craft custom French grille bar configurations, applied muntins, structural transoms, and interior glass partition frames. Specify exact grid ratios, arch units, side-lights, and transom panels made to structural millimetric shop drawings.
Long-haul ocean shipment to Haydarpaşa or Ambarlı ports demands zero-damage packing. Each frame is individual protective film wrapped, corner cushioned, bubble sealed, and packed into fumigation-free solid timber crates.
Istanbul’s complex microclimates—ranging from humid coastal zones along the Marmara Sea and Bosphorus Strait to windy interior highlands like Kemerburgaz and Zekeriyaköy—require bespoke structural engineering for exterior and interior door openings.
Properties along the waterfronts of Bebek, Arnavutköy, Yeniköy, and Kandilli face constant exposure to saltwater mist and severe winter gale winds. Traditional steel Crittall frames rapidly corrode in these environments. Window Wurx supplies marine-grade anodized or PVDF-coated aluminium French Crittall doors featuring double Low-E toughened glass filled with 90% argon gas. This guarantees zero corrosion, U-values below 1.3 W/m²K, and resistance to wind loads up to 3500 Pa (Class C5).
Renovating historic masonry buildings and turn-of-the-century brick industrial structures requires strict aesthetic alignment with original wrought steel window grids while dramatically upgrading occupant comfort. Our ultra-slim aluminium Crittall casement and pivot doors retain historical proportions while introducing multi-point perimeter locking, integrated EPDM weather gaskets, and acoustic laminated glass (STC 40+ dB) to block heavy metropolitan traffic noise.
Modern corporate headquarters, luxury boutique hotels, and fine dining venues require sophisticated interior glass partitions to separate meeting rooms and dining zones without obscuring ambient natural sunlight. We supply non-thermal slim aluminium internal Crittall partition walls, sliding barn doors, and concealed pivot doors featuring toughened clear, frosted, fluted (reeded), or tinted acoustic glass build-ups.
Ultra-slim 18mm sightline aluminum profiles designed for minimal visual impact.
Turkey’s construction and architectural sector operates under strict energy efficiency regulations mandated by the Turkish Building Energy Performance Directive (BEP-TR) aligned with European Norms (EN). Buying directly from a certified OEM manufacturer in Foshan offers substantial cost optimization for Istanbul-based developers and dealers without compromising on quality or regulatory compliance.
