KGB (Kontrollgruppen Bygg as) is a company that offers consultancy services within the construction and energy sector. The company specializes in energy efficiency and carries out independent checks of wet rooms and tightness. Through modern technology, such as thermography, they uncover air leaks by putting the building under negative pressure. This helps to identify accidental leaks that can affect the building's energy efficiency.
In addition to density control and thermography, KGB offers energy consultancy, where they assess the building's energy use and make recommendations for improvements. The company places great emphasis on quality and reliability in its services, and they are engaged in sustainable solutions to contribute to a more energy-efficient society. KGB operates in Trondheim and offers free inspections for customers who wish to have their buildings assessed.
