Kingflex
Engineered rubber foam and open-cell insulation sheets tailored to meet BCA (Building Code of Australia) requirements.
Kingflex Insulation Co., Ltd. is a premier manufacturing and trading combo for thermal and acoustic insulation products. Our R&D and main production facilities are located in the energy-saving green building materials hub of Dacheng, China.
Operating under a philosophy of environmental conservation and consumption reduction, Kingflex designs, manufactures, and supplies complete insulation systems globally. From standard duct configurations to cryogenic storage linings, our products ensure sound attenuation, thermal resistance, and durability.
With more than 40 years of industrial heritage trace-back to our establishment under the Jinwei Group (est. 1979), we have scaled up production to service large-scale global developments, including infrastructure projects across Australia and New Zealand.
Kingflex products have successfully obtained global standards approvals including BS 476 (Parts 6 & 7), CE, REACH, ROHS, UL94, and ASTM, ensuring compliance with Section F5 of the Building Code of Australia (BCA) governing acoustic performance.
A technical guide on noise mitigation, building compliance, and environmental sustainability in New South Wales.
Commercial and multi-residential builds in Sydney face strict acoustic scrutiny. The NSW Environment Protection Authority (EPA) and local municipal councils enforce stringent noise limits, particularly around high-density zones like Green Square, Parramatta, and Sydney CBD. Compliance with AS/NZS 2107 (recommended design sound levels) and BCA requirements demands predictable noise reduction coeffecients (NRC) from all building materials.
Sydney's coastal climate features humid summers and cool winters. In central air conditioning systems, poor thermal-acoustic insulation leads to condensation, leading to mold growth and structure degradation. Our open-cell and closed-cell elastomeric matrices provide a dual function: high-efficiency sound absorption and built-in vapor barriers with exceptionally low water permeability.

We minimize project delays through container-direct shipping models from our plant to Sydney ports. With strong raw-material sourcing, our clients avoid the typical regional supply shortages of industrial insulation materials.
Our engineers customize thickness (6mm - 50mm) and laminate densities to meet project specific sound insulation requirements (STC or Rw ratings), optimizing noise reduction in complex layouts.
Aligned with Australia's path toward net-zero buildings, Kingflex foam products contain no CFCs, HFCs, or HCFCs, supporting the Green Star rating system in New South Wales.
