Installation instructions

Uplift the existing floorboard / chipboard floor to expose the joists and cavity. Clear the cavity and install 100mm RWA45 Rockwool into the cavity at the bottom leaving an airgap at the top of the cavity. Friction fit the insulation tight within the cavity and infill any small gaps with insulation.


Ensure your joists are level. You can pack out the top of the joists to level them or in extreme cases strap new timbers to the existing joists to level them. Replace the floorboards or install a new sublfloor, screw the sub floor down into the joists to form a structural subfloor. Install the dB RD Flanking strip around the perimeter of the room, touching the floor and vertically up the wall. Install the dB Panel 28 over the subfloor, push it tight to the perimeter strip around each room. Lay the dB Panel 28 brick bond pattern off setting the joints. Use dB Panel PVA adhesive between the tongue and groove joints. Do NOT mechanically the dB panel to the sub floor, this is a floating floor treatment. The dB RD flanking strip can then be cut flush. It can be returned over the top of the floor under the skirt and cut at this point.


Your desired floor finish can then be installed onto the chipboard surface. Check with your floor manufacturer on installation instructions over acoustic flooring.
