Lotte Construction announced on the 21st that it signed a Memorandum of Understanding (MOU) for the 'Joint Development of High-Performance Floor Impact Sound Insulation Structures' on the 18th at Lotte Chemical's Uiwang plant, together with Lotte Chemical, a company specializing in eco-friendly materials, and EPS KOREA, a specialized company holding numerous excellent technologies for inter-floor cushioning materials.

Prior to this MOU, Lotte Construction established a noise and vibration solution team composed of 13 experts with master's and doctoral degrees in February to achieve zero inter-floor noise.

Floor impact noise, which causes inter-floor noise, is commonly divided into two types. 'Lightweight impact noise' occurs when hard and light objects such as spoons or plastic fall, and 'heavy impact noise' is caused by heavy and large impacts such as heels, basketballs, or hammers. Lotte Construction will begin developing cushioning materials effective in reducing both lightweight and heavy impact noises to mitigate inter-floor noise.

The new cushioning material to be jointly developed will primarily use EPP (Expanded Polypropylene), an eco-friendly material produced by Lotte Chemical. The EPP material is known to be particularly effective in reducing lightweight impact noise compared to EPS materials, which are the main materials for existing inter-floor cushioning materials, and it is expected to also provide relatively good performance in reducing heavy impact noise.

Through this research, Lotte Construction aims to achieve a reduction in inter-floor noise using the EPP floor cushioning material, which will be commercialized for the first time in Korea. The EPP material is also eco-friendly, producing less carbon emissions upon disposal compared to the existing EPS material.

Park Soon-jeon, Head of Technology Research at Lotte Construction, said, "Through this joint research, we expect to simultaneously achieve three goals: developing technology to reduce inter-floor noise, strengthening eco-friendly and ESG management, and fostering win-win cooperation with small and medium-sized enterprises."
