The studio walls are going up! Note the resilient channel onto which the sheetrock will be fastened (the horizontal metal strips). The resilient channel acoustically isolates the sheetrock from the stubs. The black strip visible at the top of the walls is the IsoPad from A/V RoomService. Also note that none of the sheetrock seams overlap. This helps to further reduce the transfer of sound in and out of the studio. About half of the sheetrock is up in the studio. The first layer of sheetrock is fastened to the resilient channel (not the studs), then a coat of RoomDamp is applied and finally one more layer of sheetrock. All gaps are sealed with acoustic sealant. Even though the studio walls are not yet complete, the room is noticeably more quiet than the rest of the house.
This week the windows were installed and some of the siding. The interior of the studio is still bare studs.
Norman Varney of A/V RoomService was able to get us an upgrade of their IsoPad product because their supplier was out of the standard version. They provided the upgraded IsoPad for the same price. Thanks Norm!
IsoPad acts as a buffer between the walls, floor and ceiling, allowing each to be acoustically isolated from each other. In other words, the walls, floor and ceiling are not in direct contact with each other. This stops vibrations or resonance in one surface from transferring to another.
