Operating principle

Maximum protection against mould and moisture damage to structures

INTELLO membranes work on the principle of climate-controlled membranes: the fleece membranes provide a seal against moisture in winter, whereas the molecular structure becomes more open in summer and facilitates drying out in a reliable manner.
