Engineered for maximum thermal isolation, customizable privacy control, and visual ergonomics across Surabaya's commercial skyscrapers and residential towers.
Understanding East Java’s epicenter of commercial growth, sustainable building standards, and tropical environmental imperatives.
As the economic powerhouse of East Java and Indonesia’s second-largest metropolis, Surabaya is undergoing an unprecedented architectural transformation. From the bustling commercial corridors of Jalan Tunjungan and Mayjend Sungkono to the expanding luxury developments in West Surabaya (CitraLand and Pakuwon City), the city's skyline is rapidly dense-building upward. However, designing high-performance glass facades in Surabaya presents unique thermodynamic challenges driven by its tropical savanna climate (Köppen Aw), direct equatorial solar irradiance, and high coastal humidity originating from the Madura Strait.
Modern building developers and engineering consultants across Surabaya are faced with stringent energy performance targets. With ambient peak temperatures frequently hovering between 32°C and 35°C year-round, unconditioned solar heat gain through conventional glass curtains imposes extreme cooling loads on commercial HVAC systems. Standard tinted or reflective glass often falls short by either permanently darkening interiors—requiring artificial electric lighting—or reflecting excessive glare into adjacent urban spaces. This is where dynamic switchable Smart Tinting Glass Technology serves as a game-changing paradigm shift for modern Indonesian architecture.
In accordance with Peraturan Wali Kota Surabaya No. 80/2018 regarding Green Buildings and the Green Building Council Indonesia (GBCI) Greenship Certification framework, commercial properties must lower overall Energy Use Intensity (EUI). Integrating dynamic PDLC (Polymer Dispersed Liquid Crystal) and Electrochromic (EC) smart tinting glass allows structural engineers to dynamically manage Solar Heat Gain Coefficients (SHGC) from a clear 0.65 state down to an ultra-efficient 0.09 tinted state. This intelligent transition eliminates solar heat before it penetrates the thermal envelope, directly contributing to GBCI energy points and meeting strict Indonesian National Standards (SNI 15-0048-2005 for safety glazing).
A comprehensive engineering comparison of active and passive tinting mechanisms for structural applications.
Utilizes liquid crystal droplets suspended in a polymer matrix sandwiched between conductive ITO films. Upon applying 48V-60V AC, liquid crystal molecules align, instantly turning the glass from opaque frosted white to 88%+ optical clarity within 100 milliseconds.
Ideal for exterior curtain walls facing direct Surabaya sun exposure. Employs tungsten oxide ($WO_3$) intercalation layers to reversibly change color tint levels under low-voltage direct current (1.5V to 5V DC), gradually absorbing solar radiation without obstructing exterior views.
Combines smart tinting interlayers inside double or triple-glazed Insulated Glass Units (IGU) equipped with soft-coat Low-Emissivity silver layers and argon gas fill. Yields exceptional U-values down to 1.1 W/m²K to repel harsh East Java ambient humidity and heat.

Combining world-class German equipment, ultra-precise quality assurance, and seamless global logistics to serve East Java's major construction developers.
BYG.GLASS, as a large high-end glass source production enterprise, sets research and development, production, and sales in one. Its products cover tempered glass, insulating glass, art glass, and premium architectural glass products. Since its establishment in 2020, it has always been committed to creating all kinds of high-end decorative and functional glass products for domestic and foreign high-end brand doors and windows, structural curtain walls, luxury bathrooms, high-end hospitality, star hotels, and elite commercial spaces, satisfying diversified market demands with exquisite technology and uncompromised quality.
Located in Shijie East Industrial Park, Nanhai District, Foshan City, Guangdong Province, our headquarters covers an expansive area of more than 20,000 square meters. Adhering to the core development policy of "quality is king, delivery first, service first", as well as the business philosophy of "stable foundation, change and innovation", BYG.GLASS has successfully operated three specialized production divisions: Tempering, Hollow (IGU), and Technology Processing.
Full-chain quality control using imported raw float sheets and German-made processing equipment. Our flatness error is maintained at ≤0.3mm, light transmittance exceeds 91% in clear state, impact resistance is 20% better than industry standards, and factory defect rates stay below ≤0.05%.
Covering float glass thickness from 3mm to 19mm, 12 distinct color tint systems, and integrated multi-functional options like fire-rated, acoustic, or bulletproof laminates. Intelligent scheduling ensures small custom orders ship rapidly while managing 5-meter structural curved glass orders effortlessly.
With 3 national production bases and 6 regional warehousing centers totaling 100,000㎡, our raw materials turn over within 3 days. We offer direct sea-freight routing to Tanjung Perak Port in Surabaya with specialized export crating and anti-desiccant packaging.
Professional & Efficient – Your Trusted Trade Partner. Our factory's container loading team is a highly efficient and professional group, known for its precision, speed, and teamwork. With extensive experience, the team expertly manages loading processes to ensure optimal space utilization while strictly adhering to safety protocols. They pay close attention to detail, meticulously checking lists to prevent errors, and skillfully operate loading equipment to safeguard cargo integrity against high-humidity sea transits.
Deploying switchable privacy and active tinting across corporate, medical, and residential projects.
In high-density commercial centers like Plaza Surabaya or HR Muhammad towers, PDLC glass eliminates the need for dust-collecting blinds. Conference room partitions instantly transition from clear glass to fully private projection screens with the touch of a remote control or smart wall panel.
Major healthcare institutes across Surabaya rely on non-porous switchable smart glass for ICUs, operating theaters, and isolation suites. By embedding PDLC films between double-tempered layers, surface hygiene is maximized, completely preventing bacterial growth typical of fabric curtains.
Penthouse apartments in West Surabaya facing west receive harsh afternoon sun. Electrochromic double-glazed facade panels selectively filter heat-inducing infrared radiation while keeping ocean views of the Madura Strait crystal clear without interior thermal spikes.
Ensuring smooth procurement, sea-freight handling, and regulatory approval for engineering projects.
The next frontier of smart glass in tropical regions like Surabaya involves combining Electrochromic technology with semi-transparent Perovskite Photovoltaic (BIPV) cells. These self-powering facade windows generate clean electricity from intense tropical sunlight while dynamically adjusting tint levels to optimize indoor cooling.
Procuring custom architectural glass for projects in East Java requires strict adherence to customs regulations at Tanjung Perak Port, Surabaya. Key procurement checkpoints include:
From patterned smart facades to high-gloss painted and high-end safety laminated solutions for any project requirement in Surabaya.
Addressing structural, electrical, and maintenance inquiries for architectural smart glass installations.
Our smart glass units designed for tropical climates utilize specialized EVA (Ethylene Vinyl Acetate) or high-grade PVB lamination films with edge-sealed hydrophobic barriers. This prevents moisture ingress and delamination even under Surabaya's average 75%-85% humidity and severe coastal salinity near Tanjung Perak.
PDLC glass operates as "Fail-Safe Opaque." When power is cut, the liquid crystals relax into a randomized state, making the glass completely frosted and private. For facade projects requiring continuous clarity, we supply battery backup UPS systems or Electrochromic alternative options.
By reducing peak air conditioning energy consumption by up to 35% and eliminating interior window blinds maintenance, commercial high-rise projects in Surabaya typically achieve full capital investment payback (ROI) within 2.8 to 3.5 years.
Yes. All smart glass panels are custom-manufactured to size prior to tempering and lamination. We engineer precise notch cutouts, hinge holes, and concealed busbar wire outlets tailored specifically to your structural shop drawings.
