July 19, 2001: Underfloor ventilation |
|
 |
Nearly 30 years have passed since my house was built. The house was partially reformed nine years ago and some parts of the floor were replaced recently. As we built a spacious terrace on the south of the house, the underfloor ventilation became insufficient. Yes, a free-from-dampness atmosphere is needed to protect the house from the attack of termites anyway. |
 A brochure of a termites eradicator appeals the effectiveness of dry underfloor. |
|
 They say the underfloor ventilation will be good not only for house but also for human health. |
|
 This is why we have decided to set the equipment. |
|
 |
Machine-packed small car came to my house today at last. |
| Blue sheets were spread from the entrance to the Japanese room. |  |
 |
The small hole in the Japanese room is the inlet to the underfloor. |
 |
 |
| The instant look of the underfloor looks like clean, but the southern part of the ground has dampness. | |
| Hot humid day is bad for the construction work in the outdoor and under the floor. |  |
 |
 |
| The ventilation grid is removed and the opening is widened a little to set up the fan. | |
 |
Well, the fan was set perfectly. |
| The wet air will come out from this opening. |  |
 |
 |
| The ventilation system works automatically from 10:00 a.m. through 3:00 p.m. daily. I hope my underfloor atmosphere will become dry and clean. Thank you very much for the hard works. | |
