    What does everyone think about this? The coefficient looks really impressive for a hard product - no idea how it achieves that?

    Sound absorbing plaster, do you mean absorbing sounds made in the room or noise coming in from the other sides of the walls or ceilings?

    At 27mm thick it seems more than possible. Could do with something like that here so will be following this with interest.

    What's the difference in sound levels compared to 2 boards of DB and skim finish?

    Was wondering that too also. Suspect that would be a whole lot cheaper, but indeed, how does that compare acoustic wise?

    This particular product is used to reduce reverberation and noise levels within the room in which the noise is generated. Acoustic plasters are (often much) thicker than regular plasters and are normally aerated using a foaming agent (such as aluminum powder) to incorporate pores that absorb and convert the sound wave energy into heat.

    That's aimed at reducing sound transmission, rather than reverberation, so not comparable.
