Breathable wool insulation
Japanese houses have been built using wood since ancient times, due to the availability of high-quality timber nearby. Even in modern times, wooden construction remains central to residential architecture due to cost and ease of processing. In an era without insulation materials, the difference between outdoor temperatures and indoor temperatures was minimal, and "condensation" was not a significant issue for homes. However, modern houses achieve a certain level of airtightness even without special construction methods or technologies, which increases the possibility of condensation occurring within walls. Even durable wood can significantly decrease in lifespan when it absorbs moisture, leading to the growth of decay fungi. Additionally, damp wood is a favorite food of termites. Methods such as increasing density to prevent moisture from entering walls or using external wall insulation have been considered; theoretically, these seem beneficial, but it is common knowledge on-site that ensuring walls remain moisture-free for over 20 years is challenging. Eliminating moisture in Japanese wooden houses is difficult, so we should consider how to coexist with moisture.

Company information
"Wood" absorbs carbon dioxide (CO2), emits oxygen (O2), and stores carbon (C), effectively trapping "carbon dioxide" in the form of "carbon" within "wood." This process is called "carbon fixation." Wood has excellent environmental cost performance. Muramoto Co., Ltd. has made "timber sales," which is considered highly important when thinking about the environmental impact on the Earth. It is often labeled as a "culprit of deforestation" (a misunderstanding). However, judging solely from one perspective that "using timber" harms the global environment is very shortsighted when it comes to utilizing the wonderful power of "wood." By "correctly utilizing timber," we can not only fix carbon dioxide on Earth in the long term but also rejuvenate and revitalize mountains by appropriately repeating the cycle of afforestation and logging over suitable periods. As professionals in timber sales, our company advocates and implements ways to use "timber" as a resource that enables appropriate renewal for all those who "use wood," "live in wooden houses," and "inhabit regions where wood grows," in a manner that contributes positively to the global environment.
