Insulation material born from natural resources, gentle to people and the Earth.
A thermal insulation material made from carefully selected virgin wool blended with special hollow polyester. It prevents wall condensation with high humidity control, prolongs the lifespan of structural materials, and suppresses the growth of mold and dust mites. Additionally, it helps maintain indoor humidity around a comfortable 50%, contributing to reduced utility costs for air conditioning and humidifiers. There is also a "worry-free condensation guarantee" of up to 50 years. Furthermore, it adsorbs and decomposes unpleasant odors from tobacco and pets, and effectively removes volatile organic compounds (commonly known as VOCs) that can cause sick house syndrome. It contains a lot of air, has a high vibration-damping effect to suppress vibrations, and is effective in reducing sound leakage between floors and external noise.

Company information
Our company is engaged in the development and manufacturing of "Thermo Wool," a wool insulation material. Japan's high-temperature and high-humidity environment makes it very difficult for people to live comfortably and places a significant burden on housing. There are current challenges in preventing damage to homes from issues such as mold and sick house syndrome caused by internal condensation, as well as the deterioration of wood. "Thermo Wool" is an insulation material made from natural wool that has very high moisture regulation performance, making it effective for preventing wall condensation. Since its launch 20 years ago, there have been zero condensation issues, demonstrating its proven track record. It maintains a comfortable indoor humidity level throughout the year, reduces unpleasant odors with its deodorizing properties, creates a quiet space with its sound-absorbing qualities, and improves air quality. Additionally, our company manufactures other products such as polyester insulation "Power Max," "Floor Insulation Power Dry," retrofittable "Sound Absorbing Panel Sound Sphere," and "Deodorizing Panel Hayakawa." We sincerely confront the issues faced by living environments, aiming to be genuinely beneficial to both people and homes, ensuring health and safety, maintaining an environmentally friendly process from manufacturing to disposal, and allowing our customers to experience this value.
