About This Product
Whether you're an architect or contractor, Knauf High Performance Boards are designed to make your life easier.
The unique, patented Knauf Silentboard is a superior sound reducing plasterboard. Drywall partitions using Silentboard will outperform the sound reduction of traditional plasterboard and solid masonry walls across a wider range of sound frequencies.
Silentboard can be applied to existing boards, upgrading their sound reduction without the need for disruptive deconstruction.
Used in a Knauf drywall system, this sound reducing board provides better sound reduction than a double thickness brick wall or a standard twin framed party wall, with a considerably smaller footprint, increasing the saleable floor space. In some cases this may add the capacity for an additional room or apartment.
Silentboard achieves better sound reduction using fewer components than other partitions, giving a less complex design. Simpler construction on site will also speed the building process and reduce labour costs.
- Thermal conductivity: 0.24 W/mK
- Compliance (to EN 520 Classification): Type D, F & R
- Reaction to fire: The National Classification is “Limited combustibility” but the European Classification is rated as “A2”.
- Tapered edge - differing from standard Tapered Edge as is rounded.
As Knauf Silentboard is installed using the same techniques as other plasterboards, it’s quick and simple to install.
This highly versatile sound reducing board for walls and ceilings can be used for both new and existing buildings. Knauf Silentboard can be used in partitions, suspended ceilings, linings and curved partitions where greater acoustic performance is required. Ideal for cinemas, entertainment complexes and other buildings where low-frequency sounds are an issue.
- 625mm x 2000mm = 1.25m² 625mm x 2400mm = 1.5m² 625mm x 2500mm = 1.56m²
- What is the weight of the board?
12.5mm – 17.5kgm²
- What is the density of the board?
To work out the density you take the mass of the board divided by the thickness of board in metres: 1400 kg/m3 .
- What colour is the board?
Brown face with a brown backing.
- What fire rating does the board give?
We test fire resistance performance using the complete Knauf system such as a partition wall, ceiling or floor, and it is the complete Knauf system that will achieve a fire rating. This means the board alone cannot be given a fire rating. Contact Knauf Technical Services for more information.
- What acoustic performance does the board give?
We acoustically test the board on a full Knauf system; it is the system that will achieve an acoustic rating. Contact Knauf Technical Services for more information. Single frame partitions achieving ratings in the 70s for dB Rw are possible.
- What is the acceptable moisture content?
If the board has been exposed or semi-exposed for a brief period, it is common for those inspecting it to use a damp proof meter such as a Protimeter, in such cases we would recommend as a rule of thumb that the board should be suspected of lasting damage if the reading exceeds 16-18. Below 16 is acceptable.
- What are the manufacturing board size tolerances?
In accordance to EN 520:2004 Knauf manufacturers its board to the below tolerances: Width +0/-4 mm Length +0/-5 mm Thickness +0/-5 mm
- What is the maximum finish weight that can be applied to the board?
- Can I use Knauf Silentboard on a normal partition?
Yes, however we would recommend the use of a Knauf MW Stud for fire and acoustic performance. Contact Knauf Technical Services for more information.
- What is the minimum bending radius?
All Documents including brochures, datasheets, declaration of performances and MSDSs: Resources and Literature
