As urban growth accelerates in Indonesia, facade performance is coming under greater focus. This year, SunFrame will showcase its curtain wall solutions at BDExpo Indonesia 2025, presenting practical applications and engineering innovations for high-performance facades. Here’s how SunFrame integrates engineering and policy alignment to support high-performance solutions.
Deepening Curtain Wall Design for Quality Execution
1. Indonesia’s Urban Growth Fuels Curtain Wall Demand
With the large-scale development of Indonesia’s new capital, Nusantara, and simultaneous upgrades in cities like Jakarta, the country is undergoing significant urban restructuring and focused public infrastructure expansion.
In this wave of construction, the performance of building facade systems is becoming a central focus. Indonesia’s typical climate which is characterized by high humidity, intense UV exposure, strong wind pressures, and heavy rainfall, poses challenges to curtain wall systems that far exceed those of normal conditions:
◆ Wind pressure ratings keep increasing , especially for high-rise buildings.
◆ Drainage and sealing under heavy rain have become key design priorities.
◆ Long-term durability and ease of maintenance directly affect service life.
According to the draft update of Indonesia’s national curtain wall standards scheduled for 2026, the industry is rapidly shifting toward high-performance, systematized, and locally adapted solutions. This shift opens the door for brands that excel in integrated design and system delivery.
2. SunFrame’s Tailored Curtain Wall Systems for Southeast Asia
In response to Indonesia’s unique climate and environment, SunFrame has developed a comprehensive curtain wall system emphasizing safety, adaptability, and flexibility. The system is optimized for three core application scenarios. And each is followed by one or more real-world case studies from the Philippines to illustrate our practical approach.
2.1 High Wind Pressure Zones
Our curtain wall system is engineered to withstand ±5.5 kPa wind pressure and is well-suited for coastal developments and high-rise buildings.
▶ Case Highlight: Sheraton Hotel Cebu
Considering the coastal exposure, our facade engineer customized a system that could handle strong wind loads while preserving the preserving the architectural intent of an open, panoramic coastal view.
2.2 High Humidity and Heavy Rainfall Conditions
Our whole facade system is designed with a multi-stage drainage and anti-condensation structures, which can improve drainage performance and sealing reliability.
▶ Case Highlight: Camiguin Resort
Situated in a tropical environment with frequent heavy rain, this resort applied SunFrame’s enhanced sealing and drainage solution. Such a solution leads to long-term durability and indoor comfort even in challenging weather.
2.3 Diverse Building Types
The SunFrame system supports a combination of unitized, exposed frame, hidden frame, point-supported, and aluminum panel curtain wall systems, offering a high flexibility. In addition, it can fully satisfy the customized needs of various building types, including public buildings, commercial complexes, and large residential projects.
▶ Case 1: MAHI Mixed-Use Complex
The Mahi project is built to be used as an office and commercial space. For this demand, we SunFrame employs multiple curtain wall systems so as to balance functional diversity with architectural design coordination.
▶ Case 2: Marikina Valley Medical Center
This healthcare facility focuses more on user comfort and long-term reliability. Therefore, SunFrame has adopted a high-performance exposed frame curtain wall system that enhances energy efficiency and ease of maintenance for it.
▶ Case 3: RealSteel Office Facade
For this urban office project combining the modern functional requirements with a distinct architectural identity, exposed frame curtain wall is a great choice.
Overall, SunFrame’s curtain wall system has proven effective in solving the above three core challenges. Besides, it demonstrates strong tested performance and on-site adaptability, making it particularly ideal for Indonesia’s current complex and evolving construction landscape.
Building on this, and drawing from years of overseas project experience, SunFrame has also introduced three practical and locally adaptable cooperation models to help reduce project costs and simplify technical coordination.
3. In-Depth Project Integration: SunFrame’s Three Collaboration Models
Building projects in Indonesia often involve complex systems, unique certification mechanisms, and a high level of localization requirements. With years of overseas engineering experience, SunFrame puts forward three practical and adaptable collaboration models:
3.1 Internationally Certified Materials with Verified Performance Standards
SunFrame’s curtain wall components and coating systems have passed multiple international standards. See below for the certifications we have obtained to ensure consistent performance and traceability.
◆ Australia Standards:
① AS/NZS 4420.1:2016 (operable windows performance)
② AS/NZS 4284:2008 (building facades)
③ AS/NZS 2208:1996 (safety glazing materials)
④ AS 2047 (windows and external doors)
◆ US. Standards: AAMA 2603 / 2604 (coating), ASTM (air-tightness and structural performance)
◆ European Standards: EN 14351-1
◆ Japanese Standards: JIS H4100 / H8601 / H8602
◆ UK Standards: BS 6496 (coating performance)
When project teams need a local assessment of alternative materials and halal-compliant sourcing, we can also support them.
What’ s more, if the project owner requires on-site testing of a specific performance standard, we can assist in arranging for local or international third-party testing agencies to conduct the test. This guarantees that the testing results are authoritative and the process complies with relevant standards. Such services can be quoted separately upon request, with costs to be borne by the project owner.
3.2 Supporting TKDN Strategy to Improve Local Content Compliance Efficiency
Facing the Indonesian government’s growing emphasis on TKDN (local content) requirements, SunFrame creates a modular “local + imported” supply strategy. By working with local partner factories for on-site assembly or phased delivery, we help project owners meet the required compliance ratios flexibly—without compromising product performance.
3.3 Specialized Design Optimization for Extreme Climate Conditions
Taking into account Indonesia’s distinct climate features, we’ve optimized our systems for heavy rain, strong winds, and high humidity through the following solutions:
- Multi-stage internal drainage paths within vertical mullions
- Anti-backflow pressure control systems
- Ventilation-balanced cavity structure design
The optimizations have already proven effective in projects across countries with similar climates. They significantly reduce maintenance frequency and minimize the risk of systemic water leakage.
Beyond that, SunFrame can provide on-site installation support according to project needs. We can assign experienced technical supervisors to assist local workers in following standardized installation procedures. On the other hand, a small task force can also be formed to work alongside the local construction team, so both quality and schedule are met. All support services can be tailored flexibly to match the specific demands of each project.
While we address technical and on-site challenges through system integration, we also recognize the strategic importance of aligning with Indonesia’s evolving policy and market landscape.
4. Building a Collaborative Brand Advantage
As Indonesia continues to advance its “local content first” policy, foreign brands face certain challenges. The increased import duties and preferential bidding treatment for domestic brands also cause difficulties to us. But we, SunFrame, actively align with these policy directions and propose the following practical solutions:
4.1 TKDN Modular Combination Table
We provide modular TKDN compliance strategies, enabling project owners to flexibly choose between domestic and imported material ratios. This supports more accurate preparation for compliance audits without compromising system performance.
4.2 Early-Stage BIM and Technical Coordination
We engage with contractors early in the project lifecycle through BIM collaboration and technical detailing, so that we can together improve overall integration efficiency and system responsiveness.
4.3 Proposal to Set Up Joint Sample Centers
We recommend establishing joint mock-up display centers with design institutes or contractors to enhance system trust and speed up project implementation.
SunFrame is your full-process partner in system coordination and project execution rather than just your material supplier.
5. Conclusion
SunFrame - A Capable Player and Trusted Partner
SunFrame is steadily expanding its presence in the Indonesian market, committed to practicality, high performance, engineering-driven solutions, and local collaboration. We believe that true trust comes from the attitude and ability on problem solving and result delivering.
In every new project, we bring not only system solutions, but also long-term partnership value.
To achieve a successful implementation of our systems, SunFrame can provide on-site installation guidance, system commissioning support. Even more, we can deploy a small engineering team to work with local contractors during key construction stages, based on the needs of different project phases.
We make every efforts because we believe that a genuine system solution isn’t just a plan on paper but something that needs to be crafted into every connection directly on-site.
Looking ahead, we hope to grow together with Indonesian design institutes, contractors, and project owners, and become a truly reliable partner in a rapidly changing market.
