Abstract

Die Erfindung betrifft eine Wandinnenplatte zum Bedecken der Rauminnenseite einer Hausaußen- oder -innenwand im Innenausbau eines Gebäudes mit einer die Außenfläche bildenden Außenschicht und einer zwischen Außenschicht und Wand befindlichen Zwischenschicht, wobei die Außenschicht von einer festen oberen Platte aus mindestens einem anorganischen insbesondere mineralischen Stoff und die Zwischenschicht von einem Vlies gebildet ist.

Description

  • Die Erfindung betrifft eine Wandinnenplatte zum Bedecken der Rauminnenseite einer Hausaußen- oder -innenwand im Innenausbau eines Gebäudes mit einer die Außenfläche bildenden Außenschicht und einer zwischen Außenschicht und Wand befindlichen Zwischenschicht.
  • Es sind die unterschiedlichsten Platten zum Innenverkleiden von Hauswänden bekannt. Häufig haben sie keine ausreichende Dampfdiffusionsfähigkeit oder sie bilden keine ausreichende Wärmedämmung. Auch bieten sie meistens keine feste dichte Außenfläche zum Tapezieren oder für einen Farbanstrich.
  • Aufgabe der Erfindung ist es, eine bauphysikalisch robuste Wandinnenplatte der eingangs genannten Art zu schaffen mit ausreichender Stabilität, hoher Feuchte-Dampfdiffusionsfähigkeit, Kondensat tolerierend mit hohem Austrocknungspotential, geringer Wärmeleitfähigkeit und mit einer festen Außenfläche zum Tapezieren, Streichen oder Verputzen.
  • Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Außenschicht von einer festen oberen Platte aus mindestens einem anorganischen insbesondere mineralischen Stoff und die Zwischenschicht von einem Vlies gebildet ist.
  • Eine solche Wandinnenplatte besitzt aufgrund ihrer Außenschicht aus anorganischen insbesondere mineralischen Stoffen/Komponenten eine hohe Stabilität mit einer festen Außenfläche und die darunter befindliche Zwischenschicht aus Vlies sorgt für eine optimale Wärmedämmung. Hierbei weist die gesamte Platte eine hohe Feuchte-/Dampfdiffusionsfähigkeit mit einem sd Wert von 0–5 m und ein optimales Brandverhalten auf, da sie schwer entflammbar ist.
  • Vorteilhafte Ausgestaltungen der erfindungsgemäßen Wandinnenplatte sind in den Unteransprüchen aufgeführt.
  • Verschiedenste Ausführungsbeispiele werden im Folgenden näher beschrieben. Hierbei zeigt die Zeichnung eine an einer Wand befestigte Wandinnenplatte im Schnitt.
  • Die Wandinnenplatte (Hybrid platte) besitzt als Außenschicht 1 eine feste obere Platte aus mineralischen Komponenten wie Blähglas, Perlite, Bims oder einem anderen leichten anorganischen Stoff mit einer Wärmeleitfähigkeit kleiner 0,1 W/(m2K). Die Partikel sind vorzugsweise mit Wasserglas oder auch synthetischen Bindern verfestigt. Die Außenschicht 1 bildet eine feste Außenfläche 3, die sich optimal tapezieren, streichen oder verputzen lässt.
  • Die darunter befindliche, an der Innenseite einer Wand 4 befestigbare Zwischenschicht 2 besteht aus einem Spinn-, Nadel-, Meltblownvlies oder aus einer Kombination der genannten Materialien. Das Vlies wird bevorzugt nachträglich thermisch oder chemisch nachverfestigt. Für die Fasern des Vlieses werden synthetische Kunststofffasern bevorzugt wie Polyesterfasern oder Bicofasern mit Polyesteranteil aber auch Mineral-, Glas- oder Cellulose-haltige Fasern verwendet.
  • Alternativ besteht die Zwischenschicht 2 aus einem Aerogel mit einer Wärmeleitfähigkeit von kleiner 0,025 W/(m2K). Die zwei Komponenten der Hybridplatte werden entweder mit den Bindern der verwendeten Komponenten verklebt oder mit einem synthetischen oder mineralischen Kleber.
  • Die erfindungsgemäße Wandinnenplatte besitzt folgende Eigenschaften:
    • • Eine feste tapezierfähige/streichbare/putzbare Oberfläche.
    • • Sie ist diffusionsoffen (sd Wert 0–5 m bevorzugt 0,5–2 m gemäß E DIN 4108-3: 2012-01) mit einem hohen Austrocknungspotential, damit die Wand als Feuchtigkeitsspeicher erhalten bleibt und Feuchtigkeit aus der Wand in den Raum austrocknen kann.
    • • Eine Schicht hat mindestens eine Wärmeleitfähigkeit von kleiner 0,035 W/(m2K).
    • • Sie ist eine Platte nach EN 13501-1 Klassifizierung von Bauprodukten und Bauarten zu ihrem Brandverhalten – Teil 1: Klassifizierung mit den Ergebnissen aus den Prüfungen zum Brandverhalten von Bauprodukten mindestens B.
    • • Die Größe beträgt mindestens 40 × 60 cm; maximal 150 × 260 cm; bevorzugt 70 × 100 cm bis 100 × 160 cm.
    • • Die mineralische Außenschicht 1 besitzt eine Dicke von 5 mm bis 50 mm, bevorzugt 8 bis 30 mm.
    • • Die Zwischenschicht 2 besitzt als Vliesschicht eine Dicke von 5 mm bis 100 mm, bevorzugt 10 mm bis 60 mm. Bei Verwendung von Aerogel 1 mm bis 50 mm, bevorzugt 2 bis 10 mm.
