The insulation of pure sauerkraut panels is not particularly pronounced in terms of cold and warmth. Their strength lies primarily in sound insulation. In earlier times, before the development of modern insulation materials, the panels were also used as thermal insulation, which does not meet today's requirements for thermal conductivity.
Insufficient thermal insulation, excellent sound insulation
Sauerkraut panels are also known as wood wool lightweight panels or Heraklith panels. Their thermal conductivity is 0.093 watts per meter and Kelvin [W / (m x K)]. Other modern insulation materials have a thermal conductivity of 0.04 W / (m x K) which is more than half the better.

The strength of the sauerkraut panels lies in their sound insulation and sound absorption (swallowing sound). They reduce reverberation times. That is why they are particularly popular in kindergartens, schools and underground garages as suspended ceilings. This acoustic insulation can take away the reverberant sound effect in private indoor swimming pools and significantly improve the reverberation and sound in entrance areas such as hallways and hallways.
Multi-layered sauerkraut plates insulate better, but not sufficiently
Two- and three-layer products are offered to turn sauerkraut panels into useful insulation panels. A thermal insulation layer made of polyurethane or polystyrene is inserted in the intermediate layers or in the core. These plates achieve thermal conductivities of up to 0.064 W / (m x K).
Before old sauerkraut panels are torn down, you should consider adding additional insulation. Above all, pure Heraklith plates cannot be disposed of without additional costs and at no cost. Even when dismantling multilayer panels, enormous disposal problems can arise.
Since the sauerkraut panels are usually installed permanently and stably, the application of modern insulation materials is often the best choice with less effort.
Ideal for use as cladding
Sauerkraut panels can be ideally used as front walls and cladding and the resulting cavity can be filled with insulating materials such as flax or hemp fibers or expanded clay granules as bulk goods.
When the panels are plastered, they insulate sound and even relatively thin wall elements offer noise protection. Unplastered panels absorb the sound, which reduces the noise in the room and the echoing effect.Tips & Tricks If you want to use sauerkraut panels for sound insulation and acoustic insulation, you can read about the reverberation times and their effect and ease of perception on hearing and people in DIN 18041 on audibility in rooms.
