TOPDACH 3000 – leichte diffusionsoffene Unterspannbahn für Dach und Fassade

Die TOPDACH 3000 ist eine leichte, dreilagige und hoch diffusionsoffene Unterspannbahn (ca. 100 g/m²) für gedämmte und belüftete Steildächer sowie als Windsperre an Wand und Fassade. Trotz des geringen Gewichts erreicht sie einen niedrigen Sd-Wert von ca. 0,02 m.

Hohe Dampfdurchlässigkeit in der Leichtklasse

Mit einem Sd-Wert von ca. 0,02 m und 3000 g/m²/24h leitet die Bahn Feuchtigkeit zuverlässig nach außen ab - der Wert liegt unter dem vieler Bahnen dieser Gewichtsklasse. Die Wasserdichtigkeit der Klasse W1 schützt die Konstruktion vor Regen und Flugschnee.

Leicht zu verlegen

Das geringe Rollengewicht von ca. 7,5 kg macht das Handling einfach und die Verlegung zügig - direkt auf der Wärmedämmung oder auf einer Holzschalung. Der dreilagige Aufbau aus zwei Lagen Polypropylen-Vlies und einem Funktionsfilm sorgt für eine saubere Verarbeitung.

Ihre Vorteile auf einen Blick

Hoch diffusionsoffen: niedriger Sd-Wert ca. 0,02 m, 3000 g/m²/24h - die Dämmung bleibt trocken.
Wasserdicht (W1): zuverlässiger Schutz vor Regen und Flugschnee.
Leicht und handlich: ca. 100 g/m², Rollengewicht ca. 7,5 kg.
Vielseitig: für Steildach und Fassade, direkt auf der Wärmedämmung verlegbar.
Geprüft: nach EN 13859-1 und EN 13859-2, Temperaturbereich -30 °C bis +80 °C.
