Duct systems play a crucial role in ventilation systems, as they are responsible for transporting air to and from different rooms. An efficient duct system ensures that the desired amount of air distribution is achieved, which contributes to a healthy indoor climate. Correct dimensioning and insulation of the ducts are essential to minimize energy loss and noise. Furthermore, the duct systems must be designed for easy maintenance to ensure long-term functionality and efficiency.

Extraction plays a crucial role in a ventilation system, as it ensures that polluted air is effectively removed from indoor spaces. A well-functioning extraction system helps to improve air quality and creates a healthier environment. It is important to choose the right components and maintain the system to ensure optimal performance. The implementation of proper extraction can also help reduce energy consumption in buildings.
