Comparison of moisture content in underfloor support timber

Comparison of moisture content in underfloor support timber

When the moisture content exceeds 20-25%, wood decay is more likely to occur.

The effect of completely dried wood on the ventilation conditions under the floor was tested in a test house. Initially, the moisture content rises as it absorbs moisture from under the floor, but in the case of the underfloor with a "subfloor ventilation fan," 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 the case without the "subfloor ventilation fan." 【Test Overview】 <Comparison of Moisture Content in Underfloor Posts in the Test House> ■ Period: May 24, 2003 - July 27, 2003 ■ Post Size: 105×400mm, measuring three posts, the graph shows the average moisture content of the three posts ■ Measuring Equipment: Sanko Electronic Research Institute, Moisture Meter MR-200 *For more details, please refer to the PDF document or feel free to contact us.
