What should I do if the vermiculite is cracked/broken?

The material vermiculite is porous and does not withstand impacts or shocks. If the plates crack, it is usually because the material has been struck by a piece of wood or similar. It is not crucial for the insulating effect that they are cracked as long as the plates are still correctly positioned in the wood-burning stove.

Vermiculite plates should be replaced when they are worn down to about half thickness. After this, they no longer insulate optimally and cannot ensure the correct combustion temperature, nor do they protect the wood-burning stove from the high temperatures in the combustion chamber.

The plates in the combustion chamber are made of vermiculite, a specially manufactured material that withstands high heat and insulates effectively. This ensures both optimal temperature and optimal combustion in the combustion chamber.
