The system consists of two tunnel membrane layers:

First layer being the main membrane, maximum 4mm thick.
Second layer, a 2mm membrane is placed on top of the first layer.
To obtain vacuum between the two layers, the second layer membrane is delivered with an embossed surface in contact with the first layer.
