ALM, "Soundproofing Material Reducing Interfloor Noise Selected as LH Phase 1 Certified New Technology"

Rubber flooring specialist RM Co., Ltd. (CEO Man-Ok Heo) announced on the 17th that its developed inter-floor soundproofing material ‘RMFGNZ (First Green Noise Zero System)’ has been selected as the first certified new technology of 2023 by Korea Land and Housing Corporation (LH). This product uses rubber, an eco-friendly material, as its core component, contains no heavy metals, and does not emit toxic gases in case of fire. The company explained that its insulation effect is higher than that of styrofoam. A company representative stated, "Even if a basketball is bounced upstairs, the noise is not perceived downstairs."

RM Co., Ltd. features a design that replaces two existing soundproofing materials?soundproofing and lightweight foam?with a single material while maintaining floor height. It is completed with a standalone panel structure combining polymer composite materials and special pillars, and by eliminating the lightweight foam curing process, construction can be carried out regardless of the season. The installation process is also simple assembly, making it easy to install. Last year, it obtained the floor impact sound insulation performance certification from the Korea Institute of Civil Engineering and Building Technology (lightweight grade 1, heavyweight grade 2). CEO Man-Ok Heo said, "To maintain material stability and noise performance within concrete structures for decades, long-term research, development, and verification were necessary," adding, "We also acquired design technology and know-how on structural stability in the process of removing the lightweight foam process."

RM’s soundproofing material has been registered in the LH Technology Innovation Partner Mall. LH plans to apply this soundproofing material to pilot complexes soon. Earlier, in April, LH conducted the ‘2023 First LH Certified New Technology Contest’ to discover excellent new technologies from small and medium enterprises and support the application of technologies at construction sites. Selected new technologies are applied at LH sites. Furthermore, after screening, they can also be applied at social overhead capital (SOC) public institution sites, helping secure initial market channels. Since 2014, LH has selected a total of 244 new technologies through annual certified new technology contests and utilized new technologies and new materials worth approximately 130.6 billion KRW at construction sites.
