How do sash windows work for ventilation?

Sash windows operate on a vertical sliding mechanism, allowing you to open either the top or bottom sash, or both, to control the airflow. The ability to adjust the opening of the sashes gives you the flexibility to regulate the amount of fresh air that enters the room. This feature is especially useful in rooms where you may want to control the temperature or air circulation, such as kitchens or bathrooms.

The design of sash windows also contributes to their ventilation capabilities. The vertical sliding mechanism allows for efficient air circulation as warm air rises and escapes through the top sash while cool air enters through the bottom sash. This natural flow of air helps maintain a comfortable indoor environment and prevents stagnant air.

  3. Energy efficiency: In addition to ventilation, sash windows can contribute to energy efficiency.
