24-Hour Ventilation Support System "Kaze no Suke Blower 24"

Some of you may be wondering whether to introduce the effective equipment "underfloor ventilation fan" for pest control under the floor and to prevent the deterioration of the foundation (moisture control). Why is ventilation under the floor necessary? We have created a page that clearly summarizes the effects of forced ventilation and installation. The area of openings required under the floor is specified by the Building Standards Act. In short, this means that you must provide a certain area of ventilation openings for moisture control under the floor. However, when looking at single-family homes, you will find that there are always ventilation openings, whether they are square grilles or full-perimeter ventilation foundation packing methods, although the types may differ. In recent years, homes with foundation insulation methods (especially in northern regions like Hokkaido) have also been built, but in this foundation insulation method, the underfloor is connected to the interior, and the underfloor is considered part of the interior, so there are no ventilation openings under the floor to prioritize insulation effectiveness. The adoption rate of the foundation insulation method is still low, but moisture issues are not nonexistent. I would like to touch on this at another opportunity.
