Beschreibung

TOPDACH 115 – diffusionsoffene Unterspannbahn für Dach und Fassade

Die TOPDACH 115 ist eine dreilagige, hoch diffusionsoffene Unterspannbahn, die Ihr Dach trocken und Ihre Wärmedämmung leistungsfähig hält. Sie eignet sich für gedämmte und belüftete Steildächer – auch mit Vollschalung – sowie als Windsperre an Wand und Fassade.

Trocken von innen, dicht von außen

Mit einem Sd-Wert von ca. 0,02 m und einer Wasserdampfdurchlässigkeit von 3000 g/m²/24h leitet die Bahn Feuchtigkeit zuverlässig nach außen ab. Die Wasserdichtigkeit der Klasse W1 schützt die Konstruktion während und nach der Bauphase vor Regen und Flugschnee.

Stark und verarbeiterfreundlich

Der dreilagige Aufbau aus zwei Lagen Polypropylen-Vlies und einem Funktionsfilm macht die Bahn reißfest und trittsicher. Die Höchstzugkraft beträgt längs/quer ca. 200/130 N/5 cm, die Weiterreißkraft ca. 120/140 N. So lässt sich die Membran schnell, sauber und sicher verlegen.

Ihre Vorteile auf einen Blick

Hoch diffusionsoffen: Sd-Wert ca. 0,02 m, 3000 g/m²/24h – die Dämmung bleibt trocken.
Wasserdicht (W1): zuverlässiger Schutz vor Regen und Flugschnee.
Reißfest: Höchstzugkraft ca. 200/130 N/5 cm für sicheres Arbeiten.
Vielseitig: für Steildach und Fassade, direkt auf der Wärmedämmung verlegbar.
Geprüft: nach EN 13859-1 und EN 13859-2, Kälteflexibilität bis -30 °C.
