SEOUL, Dec. 13 (Korea Bizwire) – Reducing inter-floor noise presents a significant challenge for construction companies, especially in light of the government’s recent announcement that apartments failing to meet new inter-floor noise standards will not receive construction approval.
Despite the government’s initiative to address inter-floor noise concerns, it is imperative for construction firms to devise effective strategies for noise reduction. This is crucial not only to uphold their reputation but also to avoid consumer rejection, particularly in the current real estate market where the demand for high-quality apartments is evident.
In response to this demand, construction companies are actively racing to innovate technologies aimed at minimizing inter-floor noise. Apart from establishing dedicated research facilities and teams, they are leveraging advanced technologies from sectors such as the automobile, space, and aviation industries.
For instance, Hyundai E&C’s H-Silent Lab, a comprehensive research and demonstration facility, recently introduced a set of four inter-floor noise reduction systems collectively known as the ‘H-Silent Solution Package.’ Hyundai E&C utilizes a simulation evaluation method that replicates real living conditions to identify frequency bands susceptible to inter-floor noise, employing analysis techniques from diverse fields.
GS E&C, on the other hand, operates an eco-friendly building research team at the Yongin Institute of Technology. The team has successfully developed a four-layer floor structure awarded the ‘Interfloor Noise Class 1′ rating. Subsequently, in October, a five-layer floor structure was introduced to further minimize inter-floor noise through increased floor finish thickness and the application of high-elastic buffer materials.
Unlike conventional noise reduction methods, GS E&C’s technology offers the advantage of being applicable in the construction of large apartment complexes while maintaining floor quality consistently.
POSCO E&C has also contributed to noise reduction efforts by introducing a specialized ‘floor sound insulation system’ designed for remodeling projects. This innovative method incorporates a composite sound insulation structure utilizing dustproof modular boards, high-specific gravity mortar (cement dough), and expanded thermoplastic polyurethane (ETPU) materials.
The commitment of construction companies to minimize inter-floor noise is not only driven by regulatory compliance but also by the recognition of its impact on brand awareness. In today’s market, the level of inter-floor noise reduction technology is disclosed in sales announcements, emphasizing the industry’s transition from mere floor reinforcement to holistic technological solutions encompassing walls and ceilings.
