GS Construction announced on the 12th that it will take full-scale action to reduce noise between floors in apartment buildings in collaboration with LX Hausys.

On the same day, GS Construction signed a memorandum of understanding (MOU) with LX Hausys for 'collaborative development of high-performance inter-floor soundproof floor structures.'

GS Construction plans to conduct research on developing inter-floor soundproof floor structures that use high-performance polyurethane, independently developed by LX Hausys as a cushioning material for inter-floor soundproof floor structures, in apartment floor construction to ensure performance in floor impact sound measurements at the time of occupancy.

Previously, GS Construction had been conducting research on floor structures that can stably implement inter-floor soundproof performance even at the time of occupancy. Both companies agreed that effective noise reduction between floors requires a combination of materials, structural technology, and on-site quality control, and thus decided to jointly engage in research and development.

The floor structure applying the polyurethane cushioning material independently developed by LX Hausys participated in the '2024 High-Performance Floor Impact Sound Insulation Structure Technology Contest' conducted by the Korea Land and Housing Corporation (LH) last year, achieving the highest inter-floor soundproof grade 1 for both lightweight impact sounds such as chair dragging and heavy impact sounds such as children running.

GS Construction will develop a floor structure that can stably secure quality based on the polyurethane cushioning material prototype developed by LX Hausys and will seek certification. Subsequently, it plans to prepare construction specifications so that the technology can be applied in actual field construction.

The floor impact sound insulation structure jointly developed by the two companies is being developed with the goal of commercialization in 2026, and once the next-generation floor impact sound insulation structure is developed in the second half of this year, it will be applied to key contracted complexes.

A GS Construction official said, "Until now, cushioning materials used for inter-floor noise reduction have been limited to styrofoam (EPS) and synthetic rubber (EVA), which has posed limitations on the development of inter-floor soundproof technology. Through this MOU, we will develop more effective noise reduction technology between floors through joint research and development with LX Hausys, which has excellent R&D capabilities, and we will do our best to solve the inter-floor noise problem through early commercialization."
