DKI Jakarta, operating under a tropical monsoon climate (Köppen Am) characterized by high relative humidity (frequently exceeding 85%) and constant ambient temperatures of 28°C to 34°C, presents extreme challenges for building utilities and HVAC design. Under these severe conditions, structural condensation control becomes the single most critical factor for central air-conditioning, chilled water piping, and mechanical ventilation networks.
Without proper high-density closed-cell elastomeric rubber insulation, condensation on cold metal surfaces is inevitable. This phenomenon leads to corrosion under insulation (CUI), dramatic drops in chiller efficiency, structural ceiling damage, and the dangerous spread of molds—violating local green building codes like the Greenship Rating System set by the Green Building Council Indonesia (GBCI).
Calculating the minimum insulation thickness required to prevent condensation depends on the thermal conductivity ($\lambda$) of the material and the external convective heat transfer coefficient. Because Kingflex NBR/PVC closed-cell rubber maintains an exceptionally low thermal conductivity ($\lambda \leq 0.034 \text{ W/(m}\cdot\text{K)}$ at 0°C) and a high water vapor diffusion resistance ($\mu \geq 10,000$), it allows designers to minimize insulation thickness while guaranteeing 100% dry surfaces even under extreme indoor/outdoor temperature differentials.
For instance, for a standard 6°C chilled water pipe routing through a non-conditioned mechanical shaft in South Jakarta (where ambient temperature can reach 32°C and humidity 85%), a minimum elastomeric wall thickness of 25mm to 32mm is calculated to safely keep the outer surface temperature above the 29.1°C dew point.
As Indonesia transitions toward its Net Zero Emission 2060 goal, municipal enforcement of energy-efficient buildings in Jakarta (Governor Regulation No. 38/2012 on Green Buildings) has tightened. Selecting insulation with low VOC emission characteristics, zero ozone depletion potential (ODP), and global warming potential (GWP) of less than five is paramount. Elastomeric NBR/PVC foam is non-fibrous, dust-free, and formaldehyde-free, making it the preferred standard over glass wool for cleanrooms, pharmaceutical hubs in Cikarang, and office complexes in SCBD.
For over 40 years, Kingflex (established under the Jinwei Group in 1979) has set industry benchmarks in green-building thermal materials.
Kingflex Research and Development Center features comprehensive laboratories equipped for thermal conductivity characterization, accelerated weathering, moisture permeation profiling, and structural flammability chamber tests. Guided by 8 senior chemical and design engineers, we cooperate directly with national standard bodies, assuring each batch of elastomeric NBR/PVC products satisfies both the Ministry of Energy mandates and municipal building controls in developing markets like Jakarta.
From raw material compound blending to structural foaming stabilization, every process undergoes electronic monitoring to achieve cellular uniformity (with over 98% closed cell rate), ensuring reliable long-term insulation protection.
Kingflex was established by the Jinwei Group, which holds more than 40 years of corporate history. Established in 1979, the group pioneered the manufacturing of thermal insulation materials north of the Yangtze River. Operating with energy conservation and structural durability at our core, we provide end-to-end insulation systems ranging from custom consultations, R&D engineering, and production optimization, to localized delivery and on-site assembly guidance for megaprojects across Southeast Asia.
Kingflex products comply with international building safety codes and clean air requirements.

Cryogenic Line Cladding
The building’s chilled water line specifications demanded an insulation material that could handle outdoor humidity spikes up to 90% without sweating. Kingflex Class 0 NBR/PVC elastomeric rubber foam sheets (25mm and 32mm thickness) were selected for the primary HVAC riser ducts and water piping. The project recorded a 14% improvement in chiller plant efficiency compared to adjacent towers utilizing conventional mineral wool systems, while avoiding architectural damage from mold.
