Internal Insulation

rockwool batten frame soundproof room

If you remember back to the design stage, I mentioned that there were two problems to solve. The first was to stop sound escaping from the room, and the second was to control the sound that remained in the room. We have now reached the point were the sound remaining in the room needs to be controlled.

The reverberation time of the room is going to be lowered by applying 30mm thick slabs of RWA45 Rockwool to the inner surfaces of the walls. These will be held in place firstly by horizontal battens with an internal spacing of 600mm, and then by the same technique used in stage 2 to hold the 75mm Rockwool to the outer wall.Horizontal battens at an internal spacing of 600mm

The reason for this is that in the next stage when the fabric finish is applied, you must ensure that there is wood all the way around the edges of the walls in order to act as a fixing point for the fabric. Planed 1"x2" batten was used to hold the internal absorbency.

If you have some other way o f lighting the room during construction, you can just push the hooks through the insulation. But I didn't, so I cut slits along the insulation, and fitted it around the already mounted lighting cables.It is very important that you box around the plug sockets and light switches. This will give you something to tension the fabric to. Without this, when you cut the fabric to allow the socket through, it will lose its tension and become baggy.
