Non-combustible material wall and ceiling substrate material 'Soundproof Panel 18.5'
Non-combustible materials with high sound insulation performance that demonstrate high-level soundproofing capabilities in non-combustible residential and public commercial facilities, used as soundproofing substrate materials for walls and ceilings.
■ By combining with other building materials (gypsum board, sound-absorbing wool F), we achieve D-30 to D-40. ■ It can be used in a wide range of properties, from public commercial facilities with fireproof specifications to residential buildings. * The sound insulation rating refers to the sound pressure level difference in six frequency bands at center frequencies of 125, 250, 500, 1000, 2000, and 4000 Hz. Specifically, it represents the sound pressure level difference between the sound entering the wall (incident sound) and the sound passing through the wall (transmitted sound) expressed in decibels (dB), known as the transmission loss represented by 'D value'. (Example) Incident sound level (100dB) - transmitted sound level (60dB) = transmission loss (40dB) ... resulting in D value (D-40).
