Blinds keep air flowing. The window is an opening to the outside. Even if the windows are well sealed, they still absorb some moisture, cold or heat from the outdoors. They can add an extra barrier to reduce the impact of these elements, they can help keep the house more comfortable, and help reduce energy bills. For owners of historic buildings, maintaining old, intact windows is sometimes necessary due to protection regulations. They can add insulation without changing windows.
