Simply Efficient Sound Insulation Testing

lay bricks frog up
tape and seal all joints on panel walls
fill and seal masonry joints with mortar
keep the cavity leaves separate below ground floor level
use bricks/blocks that extend to the full thickness of the wall
stagger the sockets on opposite sides of the separating wall
fix the panels or the supporting frames to the ceiling and floor only
ensure any fire stops in the cavity are either flexible or fixed to one frame only
ensure that an external cavity wall is stopped with a flexible closer at the junction
control flanking transmission from walls and floors connected to the separating wall
ensure independent panels and supporting frames are not in contact with the existing walls

allow for movement of materials
use the correct density of resilient layer and ensure that it can carry the anticipated load
fill all joints between parts of the floor to avoid air paths
seal the perimeter of an independent ceiling with tape or sealant
control flanking transmission from walls connected to the separating floor
lay resilient materials in rolls or sheets with lapped joints or with joints tightly butted and taped
continue the resilient layer up at all room edges to isolate the floating layer from the wall surface
leave a small gap between the floating layer and wall edge/skirting and fill with a flexible sealant
fix or glue the soft floor covering to the floor (floor type 1 - concrete base with soft floor covering)
fill any gap with mortar that may form between the masonry wall and the underside of the concrete floor
give attention wherever a pipe or duct penetrates the floor, to reduce flanking transmission and air paths

allow the floor base to bridge to the wall
create a rigid or direct connection between the ceiling and the floor base
use non-resilient floor finishes such as ceramic floor tiles and wood block floors that are rigidly connected to the floor base
