This system uses double layers of APB with the addition of SBM5 sound barrier mat that attenuates
impact noise transmission. This system give a large a reduction of impact sound traveling downwards.
required materials
Resilient Tape (on)
18mm APB
flooring top wear surface (4mm hardboard)
SBM5 between APB and floor boards
Installation:
the room must be cleared and swept and making sure a smooth uniform surface for laying the SBM5.
SBM5 should be layed across the direction of the floorboards and sealed at joints.
APB should be layed stait on the SBM5 followed by cailk at joints.
Before the seconf layer of APB is layed the lower layer should be sprayed with acoustic adhesive.
The second layer of APB should be layed with boards running at right angles to the first layer, caulking all joints.
lay top wearing surface with hardboard or use quiet board for better soundproofing, making sure to run a bead of sealant along all joints between boards.
screw down floor floor to make sure there are no movement, creaks or noises from boards.
