Fast Eddie and his team from Saphire Plaster hit the project at the beginning of the week. Boral have supplied their SoundStop and FireStop product for use throughout the project. We have chosen this as it provides the best finish for use in a Universal Design context.  The FireStop product will be used for all of the ceiling areas and the SoundStop will be used for most of the walls. As we used steel framing our stud walls are thinner than standard. This saved a lot of space as well as a light weight structure. The challenge then is to make it sound proof. This is where the SoundStop product comes into play. Here is an illustration that gives you an idea of the sound transmission profile of normal walls.

A standard internal timber frame and plasterboard wall has an STC of 34 and normal speech can be heard easily. By selecting the ‘Quietest’ QuietZone^TMWall System, the Sound Transmission Class is increased dramatically to STC53 so that loud speech cannot be heard. This includes SoundStop plasterboard and noise control batts.

You can clearly see in the above photos the noise reduction batts and the way the plasterboard is being installed on the steel framing. For more details you can download a Boral SoundStop installation brochure here.
