Engineered to meet the strict acoustic requirements of the Australian National Construction Code (NCC). Explore our premier open-cell and elastomeric materials optimized for thermal and sound insulation.
High-density NBR/PVC elastomeric foam designed for standard building acoustic dampening and thermal efficiency.
Advanced open-cell matrix specifically calibrated for sound attenuation across high-frequency ranges.
Acoustic wall panels providing high structural stability and sound absorption for commercial partitioning.
Excellent structural soundproofing board certified to pass international flame and smoke emission testing.
Sydney is currently experiencing unprecedented high-density urban transformation. From the expansive commercial centers of Parramatta and Barangaroo to residential developments in Mascot and Green Square, acoustic isolation has shifted from a premium option to a strict regulatory mandate.
The National Construction Code (NCC) of Australia imposes strict AS/NZS ISO 717.1 compliance standards on multi-residential and commercial spaces. Specifically, floor-ceiling systems must achieve a weighted standardized impact sound pressure level (L'nT,w + C1) of 62 or less, while partition walls require airborne sound attenuation indexes of Rw + Ctr ≥ 50.
Standard closed-cell materials fail to capture airborne reverberation inside mechanical rooms, HVAC shafts, and processing plants. This failure drives the demand for specialized, engineered open-cell nitrile rubber (NBR/PVC) formulations that block both thermal transmission and localized structural vibrations.
Sydney contractors have historically paid high premiums for localized supply lines. Kingflex Insulation Co., Ltd. offers direct factory access from Dacheng, China—the globally recognized hub of high-performance energy-saving building materials.
By integrating professional R&D with five advanced automatic production lines, we produce an annual volume exceeding 600,000 cubic meters. This manufacturing scale guarantees consistent product density, structural compliance, and stable pricing, direct from our factory floor.
Our specialized logistics channel ships directly to Port Botany, Sydney. This path minimizes freight handling costs, bypasses domestic distribution markups, and provides local mechanical engineers, builders, and acoustic consultants with certified products at wholesale rates.
Designed for maximum mechanical isolation, structural dampening, and acoustic lining inside concrete voids and partition walls.

Kingflex is established by the Jinwei Group, which carries a heritage spanning more than 40 years. Founded in 1979, the group was the pioneer of modern thermal insulation manufacturing north of the Yangtze River.
Today, Kingflex operates as an integrated manufacturing and trading powerhouse. Our production and research departments are located in Dacheng, China, a recognized hub for eco-friendly building materials. We provide solutions that cover the entire life cycle of insulation projects: dynamic design consultation, in-house R&D, customized thickness calibration, structural installation guidance, and dedicated post-sale support.
Our team consists of 8 senior research and development engineers, 6 international customer support representatives, and over 230 workers in our production lines.
Every product batch undergoes continuous testing to measure dynamic stiffness, thermal conductance, fire retardancy indices, and closed-cell consistency. Our products are fully traceable from raw chemical formulation to installation on-site.
