Properties

The white layer is placed outside and reflects solar radiation, avoiding excessive heating of the feed. This avoids unwanted fermentation.
The black layer forms an infrared barrier, again providing a more balanced temperature. The temperature must always be at an optimal level to ensure the development of lactic acid bacteria.
