In March 2021, Jeongyang SG obtained Certification of Structural Technology from the Korean Structural Engineers Association (KSEA) for its Zero-E thermal break insulation system.

The certification confirms that the submitted technology was reviewed based on scientific and engineering grounds and recognized as suitable for building structural technology.

This achievement supports the technical reliability of LBN Modular® as a structural thermal break system designed to meet both structural performance and energy efficiency requirements in reinforced concrete buildings.
