KNAUF Type H2 12.5 mm | Moisture-resistant plasterboard
Structural boards for dry constructionDescription
The classic ‘green’ moisture-resistant plasterboard: type H2 in accordance with EN 520, with reduced water absorption for interior spaces with moderate humidity — bathrooms, kitchens and utility rooms.
Knauf’s Type H2 moisture-resistant plasterboard has a specially treated core and facing that limit water absorption, for use in interiors with high levels of water vapour. It offers excellent flatness and stability, making it a suitable substrate for paint or light tiling in areas not subject to direct water spray. It can also be applied as a dry plaster to existing walls.
Which damp-proofing should I choose:
H2 provides protection against moderate damp — it is not waterproof. Depending on your requirements:
Type H2 → bathroom and kitchen walls/ceilings, away from direct contact with water.
DFH2 → when you need fire resistance as well as moisture resistance.
Diamant DFH1IR → high humidity (H1 class, ≤2.5%) + durability.
AQUAPANEL → shower cubicles/permanently damp areas/spas + waterproofing.
GUARDEX / Glasroc X → exterior / façades.
