Fresh air enters through various leaks.

When installing ventilation in a wooden house and using an exhaust channel, it is sometimes not required to organize supply ventilation. Fresh air enters through various leaks. If you want a greater air supply of air, the supply ventilation is mounted similarly by exhaust. The only thing that the openings of the air fence must be placed at the level of the first floor. It is also necessary to install a lattice and blinds on the air intake to regulate temperature indicators in the room and ventilation intensity.

Good luck!
