External insulation double ventilation exterior wall renovation method "SOIV method"

We propose a breathable exterior wall renovation suitable for Japan's climate!

Our company utilizes existing walls as insulation and creates a ventilation area on the outside to allow moisture to pass through. We then cover that side with aluminum siding, implementing the 'SOIV Method,' an external insulation double-ventilation wall renovation technique. The ventilation layer created between the siding and the existing wall controls temperature differences, creating an ideal living space that is cool in summer and warm in winter. Furthermore, it prevents indoor moisture from being trapped within the walls and expels it outdoors, thus preventing the occurrence of condensation, which can lead to dust mites and mold. 【Features】 ■ Mold and condensation have disappeared ■ Warm in winter, cool in summer ■ Maintenance-free *For more details, please download the PDF or feel free to contact us.
