How to achieve air permeability from the window in the house

Many people ask: how to maintain heat in the house, without limiting the flow of fresh air. This problem can be solved by installing wooden windows. Due to the unique structure of the wood, the air will pass into the room through the details of the window block, as well as through the outer walls and seams. Together with air, the smallest moisture particles move through wooden windows. This phenomenon can be explained by the difference between partial pressure from the outside and indoors.
