KNAUF PIANO DF | Sound-insulating, fire-rated plasterboards

High-density DF plasterboard (GKF), designed as a facing for dry construction systems in interior structures where both sound insulation and fire protection are required.

Knauf Piano DF belongs to the category of controlled (high) density plasterboards with a glass fibre-reinforced core. This combination — greater surface mass and improved structural integrity in the event of fire — makes it the product of choice for partition walls and wall/ceiling cladding where sound control and fire resistance are critical. It is used as a cladding in all interior dry construction systems with increased requirements.

What does ‘DF’ mean:

According to standard EN 520, the designation ‘DF’ describes two properties: D = controlled, higher density (greater mass per m² → better sound insulation based on the law of mass) and F = core with improved stability at high temperatures (reinforced with glass fibres). This is why a single panel simultaneously meets both acoustic and fire-resistance requirements.
