ジョイ・コス Company Profile

If it's about housing, feel free to consult us about anything!

Currently, the Earth's environment is definitely changing. To effectively utilize limited resources, we need homes that are durable and long-lasting, homes that can be heated and cooled with minimal energy, and homes that allow residents to remain healthy for a long time. There is a growing demand for homes that consider both people and the Earth's environment. The charcoal used in "Chako's House" by Joy Cos Co., Ltd. is made from carbonized cork, and this carbonized cork not only possesses the characteristics of charcoal but also offers excellent sound absorption due to its elasticity. In addition to insulation and airtightness, we have significantly resolved the issues that have been the biggest weaknesses of high-insulation and high-airtight homes, such as sound reverberation inside the house and the problem of dryness in winter. Furthermore, thanks to the adsorption properties of charcoal and the operation of a 24-hour ventilation system, it has become possible to remove harmful substances (such as VOCs that can cause sick house syndrome) from the indoor environment, allowing for homes that prioritize the health of residents more than ever before. Joy Cos pledges to contribute to society with dedication and passion for energy-saving technology, as a partner in the cultural heritage of living, in order to pass on this Earth's environment to the next generation.
