When the moisture content exceeds 20-25%, wood decay is more likely to occur.
We conducted an experiment on how completely dried wood is affected by the ventilation conditions under the floor in a test house. Initially, the moisture content rises as it absorbs moisture from under the floor, but in the case of having a "subfloor ventilation fan" installed, the moisture content of the posts stabilizes at around 20%, as shown in the graph in the image. It can be seen that the moisture content is about 5% lower compared to when there is no "subfloor ventilation fan." 【Test Overview】 <Comparison of Moisture Content in Subfloor Posts in the Test House> ■ Duration: May 24, 2003 - July 27, 2003 ■ Post Size: 105×400mm, measuring 3 posts, the graph shows the average moisture content of the 3 posts ■ Measuring Equipment: Sanko Electronic Research Institute Co., Ltd.

Company information
In the 21st century, the way human society exists on a global scale is being questioned. In this era of rapid change, what kind of aspirations should we have when engaging in business? SEIHO's new concept naturally emerged from such inquiries. "Compassion" is the new concept. Rather than pursuing extravagant ideas, we want to delve deeper into a simple concept that everyone can be confident in. We wish to return to our origins to realize this concept. In a time when a diverse array of information is overflowing, misjudging the clear distinction between "purpose" and "means" can render even effective technologies futile. SEIHO will firmly place "principles, fundamentals, and essence" as the axis of our management decisions, learning from the wisdom of past sages while creating genuine technologies and services that benefit society.
