Insulation material nurtured by the great nature.
Fiber Ace (cellulose fiber), made from wood fibers, prevents heat from escaping due to the immobile air bubbles contained in each fiber, providing an "insulation" effect. It also offers "moisture regulation" and "prevention of wall condensation" effects due to the inherent properties of wood fibers, as well as "fireproof" and "insect-repellent" effects from the boron-based agents it contains. Additionally, the high-density installation within walls provides a "soundproofing" effect. Moreover, since boron-based agents are also used in products like eye drops, they are considered "safe" materials. It is not an exaggeration to say that using Fiber Ace as internal insulation is the only way to achieve a healthy, comfortable, and long-lasting home that incorporates natural air.
