In this loud and busy world, silence truly is golden. There are times when it is a necessity and times when it is a luxury.

Knauf Silentboard rewrites the rules on drywall acoustic performance. Its patented design allows the creation of drywall partitions which outperform the sound reduction of traditional plasterboard and solid masonry walls across a wider range of sound frequencies.

The unique formulation used to manufacture Knauf Silentboard combines density with a high level of flexibility. The result is a board which offers exceptional sound reduction at both high and low frequencies. Knauf Silentboard is therefore ideal for use in cinemas, entertainment complexes and other buildings where low frequency sounds are an issue.

Knauf Silentboard has been proven to improve the sound reduction of a drywall partition by up to 5dB when a single layer is applied to one side, up to 7dB when two layers are applied to one side and up to 9dB when a single layer is applied to each side of the partition.
