The Eurovent Matt mat is used for pitched, insulated, non-insulated, boarded, ventilated roofs as a separation and drainage layer under metal coverings. Eurovent Matt is also suitable for use in ventilated and non-ventilated metal facades as a drainage and ventilation layer. Thanks to the use of a polypropylene braid in the production as a separation layer, we have achieved a space that allows full ventilation and the possibility of draining water and moisture from under the metal roofing or facade. Thanks to the Eurovent Matt weave, the service life of a metal roof or facade is extended by at least several years.
