Introduce the working principle of passive windows and doors
Passive windows and doors work on a remarkable principle. They are designed with extremely high levels of insulation. The multiple layers and advanced materials prevent heat transfer. In winter, they keep the warm air inside and block the cold from outside. In summer, they keep the cool air in and keep out the heat. They also have excellent airtightness, minimizing air leakage. This helps maintain a stable indoor climate and reduces the need for excessive heating or cooling, saving energy and providing a comfortable living environment.
