Engineered insulation systems optimized for Istanbul's dynamic architectural engineering and coastal environmental conditions.
Istanbul, bridging Europe and Asia, acts as a primary corridor for heavy manufacturing, shipbuilding, and commercial construction. With the expansion of industrial zones in Tuzla, Dudullu, and the rapid pace of urban renewal programs, structural thermal engineering requirements have reached unprecedented strictness.
Under the Turkish Standard TS 825 (Thermal Insulation Requirements for Buildings) and stringent seismic codes, structural safety, low smoke emission, and fire classifications are paramount. Non-combustible mineral wool structures, particularly A1-rated Rock Wool, provide critical structural stability in high-density commercial centers such as Maslak, Levent, and Ataşehir.
High humidity and saline air originating from the Bosphorus and Marmara Seas accelerate atmospheric corrosion on standard carbon steel piping systems. Utilizing closed-cell flexible elastomeric foams or hydrophobized rock wool blankets drastically reduces Corrosion Under Insulation (CUI) risks by keeping moisture transmission factors (μ-value ≥ 10,000) highly resilient against saline vapor intrusion.
Bridging global manufacturing strength with localized distribution capabilities to optimize cost-efficiency.

Continuous investment in engineering, testing, and production scaling since 1979.
Established under the parent Jinwei Group, which holds more than 40 years of manufacturing history. Kingway Group, established in 1979, was the first pioneer manufacturer of thermal insulation materials north of the Yangtze River. The group's cumulative manufacturing and engineering experience ensures that every consignment exported to Turkey conforms directly to European EN standard frameworks.
Our team is composed of eight professional chemical and mechanical engineers in our R&D Department, 6 international sales managers, and 230 skilled production technicians, working together to deliver zero-defect insulation panels, blankets, and tubes.








Ensuring full structural and regulatory compliance across strict municipal standards in Turkey.
Sourcing structural components for commercial, civil, or public infrastructure in Istanbul demands certified verification. Kingflex products undergo external laboratory monitoring to secure critical ratings for flame propagation, smoke toxicity, structural stability, and thermal conductivity. By offering products certified to BS 476, CE, REACH, RoHS, UL94, and ASTM standards, we simplify customs clearance at Turkish customs ports.

It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound absorption in complex environments.
Yes, our rubber foam insulation products are fire retardant, meeting strict safety standards of international building and industrial projects, including BS 476 and UL94 ratings.
Rubber foam is flexible, closed-cell, and highly moisture-proof, making it suitable for HVAC systems, refrigeration, and anti-condensation protection. Rock wool is highly temperature-resistant and completely non-combustible, designed for high-temperature industrial pipelines, structural fireproofing, and heavy thermal plants.
Yes, we support comprehensive OEM/ODM services to customize density, size, thickness, and outer protective layer finishes (such as aluminum foil or self-adhesive backings) to suit specific architectural layouts in Istanbul.
Our products have passed BS 476, CE, REACH, RoHS, UL94, ASTM, and other international certifications, ensuring compliance with global and Turkish customs directives.
Yes, all manufactured batches are assigned discrete serial numbers and manufacturing logs, ensuring raw materials and process parameters are traceable.
We can manufacture standard sheets ranging from 6mm to 50mm in thickness, with various density thresholds.
When properly installed and maintained under standard operating temperatures (-40℃ to 105℃), our insulation systems feature a service life of approximately 10 to 15 years.
We offer FOB, CIF, or CFR shipping terms. Consignments are packaged in standard maritime containers and dispatched directly to Ambarlı Port or Haydarpaşa Port. Our document packages include Certificates of Origin, CE certificates, and detailed packing lists to ensure streamlined customs clearance.
