Breathable wool insulation
Japanese houses have been built using wood since ancient times because quality timber has always been readily available. Even in modern times, wooden construction remains central to residential building due to cost considerations and ease of processing. In an era without insulation materials, the difference between outdoor temperatures and indoor temperatures was minimal, making "condensation" not a significant issue for homes. However, modern houses achieve a certain level of airtightness even without special construction methods or technologies. This creates the potential for condensation to occur within the walls. Even durable wood can suffer from decay fungi when it absorbs moisture, significantly reducing its lifespan. Additionally, damp wood is a favorite food of termites. Methods have been considered to prevent moisture from entering the walls, such as increasing density and using exterior wall insulation, which theoretically seem beneficial, but it is common knowledge on-site that ensuring walls remain moisture-free for over 20 years is quite challenging. Eliminating moisture in Japanese wooden houses is difficult; instead, we should think about how to coexist with moisture.

Company information
"Wood" absorbs carbon dioxide (CO2), releases oxygen (O2), and stores carbon (C), effectively trapping "carbon dioxide" in the form of "carbon" within "wood." This is referred to as "carbon fixation." Wood has excellent environmental cost performance. Muramoto Co., Ltd. has made "timber sales," which is ranked high in importance when considering the environmental burden on the Earth. It is often labeled as a "culprit of deforestation" (a misunderstanding). However, judging that "using timber" worsens the global environment based on just one aspect 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 repeatedly planting and harvesting forests within appropriate time frames. As professionals in timber sales, our company advocates and implements ways to use "wood" as a resource that enables proper renewal for all involved: "people who use wood," "people who live in wooden houses," and "regions where wood is grown and the people who live there," in a manner that contributes positively to the global environment.
