Trelleborg offers a special Haloten membrane worth recommending. It replaces roof foils with different vapor permeability. However, this membrane does not allow water vapor from the thermal insulation layer to pass to the outside of the roof, but thanks to its special structure, it collects the condensed water vapor on the bottom and with a system of fine hairs it perfectly drains it to the hood, and from there outside the building. This membrane is therefore able to replace roofing membranes with even very high vapor permeability.
