  • The importance of low pressure drop in an energy efficient ventilation system

    Pressure drop can be a source of wasted energy and is an important parameter in determining the overall running costs of a building’s ventilation system. In this blog post, we’ll try to explain pressure drop in a simplified way, how pressure drop data is used in ventilation design and why low pressure drop contributes to a more energy efficient ventilation system.

  • Lindab delivers ventilation system in fossil-free steel to Castellum
