Wool insulation Wool Breath

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.
