Ventilation performance 1.5 to 2 times that of conventional methods, efficiently expelling moisture from under the floor!
The Joto Kiso Packing Method involves laying Kiso packing at regular intervals between the foundation and the base, utilizing these intervals as ventilation openings. This method achieves full perimeter ventilation under the floor, increasing ventilation performance to 1.5 to 2 times that of conventional methods. It efficiently expels moisture from every corner, contributing to the creation of an ideal dry underfloor environment. Additionally, by sandwiching the Kiso packing between the base and the foundation, it prevents the base from absorbing moisture from the concrete, maintaining the dryness of the base and making it less susceptible to decay fungi and termites. The material of the Kiso packing is a unique composite (Joto composite material) developed by Joto Tech, combining the flexibility of resin with the strength of stone, making it resistant to aging and exhibiting excellent durability. We offer a wide range of options to accommodate various construction methods, including traditional methods and 2x4 construction.

We listen to the voices from the field and develop and manufacture with free thinking. That is the motto of Joto's manufacturing. Joto's building materials are described as "unique," which means not just "interesting," but in its original sense of "one-of-a-kind" and "unmatched." By utilizing our original ideas and technologies, we create distinctive and unparalleled products that cannot be replicated by other companies, and we believe that contributing to the housing industry is our value. To make Japanese homes last longer and to ensure that people can live with peace of mind for years to come, Joto will continue to challenge itself with "unique" manufacturing as a housing material manufacturer.
