GS Engineering & Construction and LX Hausys Achieve Grade 1 in LH Quality Test for Inter-Floor Noise Reduction Technology

GS Engineering & Construction announced on September 1 that the "floor structure for reducing inter-floor noise," developed in collaboration with LX Hausys, achieved a Grade 1 rating for both heavy and light impact sound in the quality test conducted by Korea Land & Housing Corporation (LH).

GS Engineering & Construction received Grade 1 certification for both heavy and light impact sound in the floor impact sound quality test conducted by the LH Quality Test Certification Center, recording 31dB for heavy impact sound and 27dB for light impact sound. The 31dB result for heavy impact sound is even lower than the Grade 1 standard of 37dB, representing the lowest level in the industry.

The newly developed floor structure incorporates "high-density open-cell polyurethane," which was jointly developed by GS Engineering & Construction and LX Hausys. This new material is highly effective at reducing inter-floor noise and has a low moisture absorption rate, allowing it to maintain consistent performance over a long period of time.

Previously, in February, the two companies signed a business agreement to jointly develop inter-floor noise reduction technology and, through collaborative research and development, comprehensively optimized the floor slab structure, cushioning material, and construction methods.

A representative from GS Engineering & Construction stated, "This new floor structure for reducing inter-floor noise is an innovative technology designed to resolve chronic issues in multi-family housing. We will continue to lead the development of technologies that enhance quality of life for our customers and set new standards for future residential spaces."

Meanwhile, GS Engineering & Construction plans to apply the newly developed "inter-floor noise reduction cushioning material" to the Songpa Hanyang Phase 2 reconstruction site and the Seongsu Strategic Zone 1 redevelopment project, both of which are key sites for strategic orders in the second half of this year.
