韩信工程建设与两家公司签署楼板隔音结构技术开发MOU

Hanshin Engineering & Construction (004960) has begun developing next-generation floor structure technology to reduce inter-floor noise in apartment buildings.
Hanshin Engineering & Construction said on the 3rd that it signed a memorandum of understanding (MOU) with Daehan Polytech and Yukyung System to jointly develop a floor impact sound insulation structure for apartment buildings. The agreement was pursued to combine each company's technological capabilities and develop a floor structure equipped with both performance and constructability, amid growing social interest in inter-floor noise and rising demand for improved housing quality.
The three companies plan to conduct technology development with the goal of simultaneously securing Grade 1 for light-weight impact sound and Grade 1 for heavy-weight impact sound, the highest grades under the Ministry of Land, Infrastructure and Transport's performance certification standards for floor impact sound insulation structures.
Hanshin Engineering & Construction will handle floor structure design and construction technology, field applicability reviews and performance verification. Yukyung System will be responsible for analyzing noise and vibration transmission paths and optimizing vibration-proofing and sound-insulation performance. Daehan Polytech will support the development of high-functionality polyurethane materials and mass production technology.
Yukyung System is a specialized company with noise and vibration control technology accumulated over approximately 30 years, and was selected as a company to carry out the Korea Land and Housing Corporation's (LH) "Floor Impact Sound Grade 1 Technology Development" project. Daehan Polytech, based on production bases in Gimpo and Gyeongju, has a system that produces everything from polyurethane raw materials to finished products, securing competitiveness in developing customized cushioning materials and in mass production.
Development will proceed sequentially, starting with material mixing and prototype manufacturing, followed by laboratory performance evaluation, full-scale mock-up testing and field applicability verification. Hanshin Engineering & Construction plans to strengthen its technological competitiveness by securing a field-applicable floor impact sound insulation structure that considers not only sound insulation performance but also construction convenience, quality stability and economic efficiency.
"The goal of this collaboration is to enhance apartment housing quality by converging design and construction technology, noise and vibration control, and high-functionality material technology," a Hanshin Engineering & Construction official said. "We will continue to develop technologies that can reduce inter-floor noise and increase customer satisfaction."
