Technology description including background system Knauf Silentboard GKF sind Gipsplatten mit einem biegeweichen Spezialgipskern für höchste Schallschutzqualität. Die Gipsplatten sind faserverstärkt für hohe Stabilität und Brandschutzqualität. Herstellung Die Komponenten der Knauf Silentboard GKF werden mit Wasser gemischt und als Gipsbrei aufden Sichtseitenkarton (untere Lage) gegeben. DieserKarton wird zuvor zur Kantenumformung an den Seiten angeritzt. Anschließend wird der Rückseitenkarton durch die Formstation auf den Gipsbrei gelegt und die Kanten des Sichtseitenkartons aufgeformt. Auf der sich anschließenden Bandstraße bindet der Gipsbrei kontinuierlich ab und wird anschließend in einem Mehretagentrockner auf die zulässige Restfeuchte getrocknet. Nach der Trocknung werden die Platten auf die gewünschte Länge zugeschnitten. Technical data: The following technical data in condition on delivery is relevant for the declared product: Declared unit: The declared unit is 1 m of Knauf Silentboard GKF with a thickness of 12.5 mm, weight of approx. 17.5 kg/m.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
