Manufactured under stringent quality standards at our 123,000 m² Foshan production complex, engineered for wind load resistance, thermal efficiency, and minimal frame sightlines in tropical urban environments.
A comprehensive technical analysis for property developers, structural engineers, facade consultants, and general contractors seeking high-performance OEM fenestration solutions across Greater Jakarta (Jabodetabek).
In contemporary tropical architecture across Southeast Asia—specifically in high-density, high-humidity urban environments like Jakarta—the demand for Aluminium Flush Windows has experienced exponential growth. Traditional window systems, characterized by stepped sash-to-frame profiles, frequently accumulate dirt, particulate matter, and stagnating rainwater during severe tropical downpours. By contrast, flush aluminum window systems position the exterior face of the window sash completely coplanar with the outer frame profile. This seamless, flat architectural exterior offers not only a clean minimalist aesthetic popular in modern Indonesian luxury villas and high-rise developments, but also provides unmatched aerodynamic and hydrodynamic performance.
Exporting custom aluminum window solutions from our manufacturing hub in Foshan to major development hubs like Pantai Indah Kapuk (PIK 1 & PIK 2), South Jakarta (Pondok Indah, Kebayoran Baru), BSD City, and Karawaci requires rigorous engineering tailored to local environmental stressors:
Designed with stepped pressure-equalized internal drainage channels and non-return flap valves. Capable of resisting wind pressure forces up to 3000 Pa (ASTM E330) and preventing water penetration under 600 Pa dynamic rain loads (ASTM E331).
Jakarta’s heavy vehicular traffic and urban density require substantial sound insulation. Our flush windows combine asymmetrical double-glazing (e.g., 6mm Low-E + 12A + 6.38mm PVB acoustic laminate) with multi-chamber EPDM seals to significantly reduce ambient urban decibels.
Equipped with high-density Technoform Polyamide PA66-GF25 thermal breaks that isolate internal heat transfer. Combined with spectrally selective Low-E coatings, our systems reduce solar heat gain (SHGC < 0.25), cutting air conditioning electricity loads dramatically.
To assist facade consultants and structural procurement leads in Jakarta with bid specification writing, the matrix below details the structural metrics of our exported aluminium flush window series:
| Specification Parameter | Standard Commercial Window Profile | Doorreme Architectural Flush Window Series | Jakarta Urban Relevance & Engineering Advantage |
|---|---|---|---|
| Aluminium Alloy & Temper | Recycled / Primary 6063-T5 | High-Precision 6063-T6 Architectural Billet | Superior tensile strength to withstand high-rise wind loads in Sudirman CBD & TB Simatupang towers. |
| Exterior Flush Plane Alignment | Offset Sash (8mm–14mm drop) | 0mm Perfectly Coplanar Flush Alignment | Prevents dirt accumulation and moisture trapping; creates sleek modern elevation lines. |
| Thermal Barrier Material | Un-insulated / Standard PVC Strip | Polyamide PA66-GF25 (25% Glass Fiber Reinforced) | Eliminates thermal bridging in air-conditioned interiors across tropical Jakarta. |
| Surface Finish Standard | Standard Mill / Anodized (10 µm) | AAMA 2605 Compliant PVDF Coating (3-Coat, 70% Fluoropolymer) | Resists severe salt air corrosion in coastal North Jakarta (PIK, Ancol, Pantai Mutiara). Tested 3,000h salt spray. |
| Hardware & Locking System | Single-Point Latch | German Roto / Siegenia Multi-Point Locking Systems | Provides maximum perimeter compression, forced-entry security, and smooth operating torque. |
| Acoustic Isolation Rating | Rw 25–28 dB | Rw 38–43 dB (with Laminated Acoustic Glass) | Isolates indoor residential environments from heavy Jakarta arterial street noise. |
How direct factory customization supports specific architectural topologies and environmental challenges across Greater Jakarta.
Environmental Stressors: Corrosive marine atmosphere, high solar UV radiation, and high wind pressure from the Jakarta Bay.
Engineering Solution: We supply flush aluminum casement and sliding windows treated with 3-coat AAMA 2605 PVDF surface finishes. The profiles utilize marine-grade 304 stainless steel hardware and double-laminated Low-E glass units, maintaining structural integrity and crystal-clear aesthetics without frame pitting or surface chalking over decades of coastal exposure.
Environmental Stressors: High ambient traffic noise from primary thoroughfares, strict aesthetic requirements, high security needs.
Engineering Solution: Our concealed-hinge flush windows feature multi-point perimeter locks and double-glazed soundproof acoustic configurations (6mm + 1.14PVB + 6mm outer / 12A argon / 6mm inner). This reduces interior noise levels to under 35 dB, providing serene living conditions while honoring modern luxury architectural designs.
Environmental Stressors: Extreme wind loads at elevated heights, seismic structural drift requirements, strict energy codes (GBCI Greenship Indonesia).
Engineering Solution: Structural curtain wall systems combined with integrated flush vent windows. Engineered with thermal breaks, low SHGC solar control glass, and seismic movement expansion joints, enabling compliance with Indonesian national structural and energy building standards.
Environmental Stressors: Rapid construction schedules, demand for consistent factory-controlled modular quality, heat gain management.
Engineering Solution: Factory-direct pre-assembled flush window sets manufactured to exact CAD elevation schedules. Standardized modular profiles allow rapid site installation while delivering high energy performance and long-term low maintenance for township housing developers.
As Jakarta’s real estate landscape evolves toward sustainable luxury and modern tropical minimalism, several key trends are influencing B2B fenestration purchasing decisions:
Two decades of manufacturing rigour, direct factory supply chains, and technical engineering support for global project delivery.
Located in Shishan Town, Foshan—China’s premier aluminum manufacturing cluster. Operating advanced German and Italian automated CNC cutting, machining, and corner-crimping production lines capable of outputting over 500,000 m² of windows and curtain walls annually.
Our team of over 800 employees includes senior facade structural engineers. We provide detailed shop drawings, structural wind load calculations, glass deflection analysis, and installation sequencing support for complex international projects.
Certified ISO9001 quality management system with compliance testing for NFRC, CE, AS2047, and CSA standards. Every unit undergoes rigorous 100% factory pre-assembly and water-tightness testing prior to ocean freight packaging.
Essential guidance for Indonesian developers, main contractors, importers, and architects ordering custom aluminum flush windows directly from China.
