Sound absorption effect from wood fibers, and sound insulation effect due to high-density filling of 55-60 kg/m³! It is an insulation material with sound insulation and sound absorption properties!
When sound enters fibrous materials like cellulose fiber, the fibers vibrate intensely against each other, causing friction, and the sound's vibrational energy is converted into (friction) heat energy. This phenomenon creates sound absorption effects. While fiberglass and rock wool are also fibrous materials and have sound absorption effects, due to gaps from installation and their lighter specific gravity, they do not achieve the same level of effectiveness as cellulose fiber. Sound is transmitted through the vibration of air. To block that sound (soundproofing), it is necessary to increase the weight of the wall to prevent the transmission of air vibrations themselves. Additionally, cellulose fiber, with a high-density filling of 55-60 kg/m3, is heavier compared to other insulation materials, allowing for high soundproofing effectiveness.

basic information
Currently, there are various types of insulation materials used in homes, most of which are made from chemical substances. In contrast, Inside PC cellulose fiber insulation is made from recycled newspaper in the United States. It contains no formaldehyde, asbestos, or fiberglass. In addition to its insulation performance, it also possesses soundproofing and sound-absorbing properties, humidity control, fire resistance, and insect resistance, making it a multi-functional insulation material.
