LX Hausys "Interfloor Noise Reduction Floor Structure Achieves Grade 1 LH Impact Sound Insulation Certification"

"We Will Continue to Introduce Technologies to Solve Interfloor Noise Problems"

On November 24, LX Hausys announced that it has obtained the highest grade (Grade 1) certification for interfloor noise from LH (Korea Land & Housing Corporation) for its floor structure product, which includes the installation of flooring materials.

Recently developed by LX Hausys, the 'Interfloor Noise Reduction Floor Structure (AF Solution 4_E)' recorded less than 37dB for both light and heavy impact sound in the floor impact sound quality test conducted by the LH Quality Testing Accreditation Center, earning the Grade 1 certificate for floor impact sound insulation performance.

The LX Hausys floor structure that received the Grade 1 certification consists of a general-purpose floor structure (slab + resilient material + lightweight foam + finishing mortar), which is commonly used in apartment designs and includes a lightweight foam layer, with LX Hausys’s 'Editon for New Apartments' flooring material installed.

The 'high-density open-cell polyurethane' resilient material, developed in-house by LX Hausys, serves as the primary vibration-damping layer against low-frequency heavy impacts generated when people walk or run. In addition, the 'Editon' flooring material further reduces the transmission of impact energy, enhancing the reduction of heavy impact sound.

LX Hausys explained that, typically, high-strength rigid flooring materials are not effective for floor sound insulation, but achieving Grade 1 certification with a floor structure that includes the finished flooring is of significant technical value. Furthermore, the test results were obtained at a GS E&C apartment construction site, which is expected to accelerate the commercialization of this floor structure product. Earlier this year, LX Hausys and GS E&C signed a business agreement and have been conducting joint research on high-performance interfloor noise reduction floor structures.

A representative from LX Hausys stated, "We will continue to introduce innovative technologies that help solve the problem of interfloor noise."
