Foundation insulation is a method of insulating the foundation that faces the outside air. The period when the risk of condensation and mold is highest with foundation insulation is from June to September of the first year after completion. The main cause is the large amount of water vapor that comes from the concrete floor. Especially, wood that contains a lot of moisture significantly deteriorates in strength, so it is important to be cautious considering durability against earthquakes and typhoons. As a solution to these moisture problems, our company has developed a dedicated underfloor dehumidifier called "Dry Pro." It effectively eliminates moisture and condensation, and is useful for preventing mold, pests, and decay fungi in the underfloor wooden components.

However, at the same time, measures against condensation during the summer must be considered. In a site where glass wool was filled using the 2x4 construction method and a vapor barrier was installed on the interior side, significant corrosion due to condensation occurred. It is believed that the interior became hot and humid, leading to condensation as it was cooled by the air conditioner on the inside. The hold-down hardware also showed white mold, and if corrosion progresses like this, it will pose problems for the durability of the building. This type of summer condensation particularly occurs in regions with high temperatures and humidity, like Japan. Therefore, it is necessary to implement sufficient measures against winter condensation while simultaneously preventing summer condensation. *For more details, please refer to the PDF document or feel free to contact us.
