China, January 20, 2026 - United Insulation, a leading exporter of building materials for insulation around the world, today successfully delivered a quantity of our premium quality glass wool boards to South Korea, totaling more than 350 tons. The delivered insulation products strictly comply with the South Korean National Industrial Standards. The requirements for our delivered glass wool insulation boards to South Korea included density levels at 24-96kg/m³, thickness levels at 25-150mm, and thermal conductivity levels at 0.034 to 0.42 W/(m*K), and our delivered products have an A1 non-combustibility fire rating.

South Korea is one of United Insulation's main markets, and the company has constantly ranked as one of China's top glass wool exports to the country over the years. Each board in the shipment meets official Korean standards and certification measures, such as:

- KS Certification, which is a standard Korean stamp needed in government projects as well as large-scale companies

- A KS certification for each batch and a test report are provided with every batch; the latter comes from a separate testing body such as an organization accredited by the Korea Standards Institute and certifies that the batch meets the codes set by the Ministry of Land, Transport and Infrastructure for buildings in terms of energy efficiency.

A one-stop service tailored specially for the Korean market

United Insulation provides strong "local" support to the Korean customer base with the following capabilities:

Authentic compliance, dependable energy-saving benefits: that is the core value of Korean clients.

Korea enforces strict measures and requirements on security and authenticity of KS certification, thermal performance, and fire rating requirements, especially when considering large factory grounds and large numbers of Seoul city center condominiums. United Insulation explains that all batches of our Glass Wool boards "are designed to pass KS acceptance on arrival," freeing up customers from Green Building Certification requirements (G-SEED), Zero Energy Building (ZEB), and Public Procurement Service bids.

Our glass wool boards that are sent to Korea are accompanied by the following sets of world-standard certifications:

- KS Certification

- CE Marking (EN 13162)

- UL 723 & GREENGUARD Gold

- ISO 9001/14001/45001

These boards utilize a large percentage of recycled glass fibers and offer excellent properties against fires. They are also resistant to settling and moisture; indeed, accelerated aging tests performed under humidity and temperature changes in Korean weather confirm their performance. Indeed, their lifespan of more than 50 years means that it would withstand Korea's harsh weather of cold winters and hot summers.
