The house, which was built using wood, by and large does not need ventilation. Wood has a unique property of "breathing" and, as a rule, such buildings do not require complex duct systems. The situation is quite different with floors and basement, where ventilation is simply necessary. Roughness and moisture can cause irreparable damage to wooden floors and significantly reduce their service life. In order to avoid this, it is necessary to take care of underfloor ventilation as early as at the foundation stage.
