Historically, wood wool panels (fibrolith) have been used as one of the insulation elements, but nowadays the panels are more often chosen due to the thermal inertia characteristic of CEWOOD panels, which in appropriate construction protects the premises from rapid temperature fluctuations. If you choose CEWOOD panels, the rooms will be cooler in the summer heat for a longer time, while they will be pleasantly warm longer when the cold weather starts. More technical data of the boards can be found here.
