Karmafloor Acoustic Batten

 Concrete Floor:

• Lay the Karmafloor Acoustic Battens around the floor perimeter, foam side down leaving a 50mm gap from any wall.  If at any point a shorter batten length is required, cut to size.
• Lay the Acoustic Battens within the perimeter battens, staggering joints at 400mm centres if using 18mm chipboard and 600mm centres if using 22mm chipboard.
• Where a lightweight non load bearing partition is to be erected above the floating floor either support this structure along its line with a double row of battens or create a ladder frame by placing cut lengths of batten perpendicular to the 2 adjacent rows of battens at 400mm centres.
• Position the Karmaplus Acoustic Perimeter Strip around the floor perimeter.
• Coat the Acoustic Battens with acoustic sealant and lay the chipboard, ensuring the joints are staggered, short edges are resting on a batten and a 10mm gap is left at the floor perimeter.
• Screw the chipboard to the acoustic battens using four countersunk screws across the face, two 25mm in from each edge and two equidistant in between.
• Glue continuously along tongued and grooved joints, removing excess glue with a damp cloth.  All joints must be tightly butted.
• Seal any gaps in the floating floor with acoustic sealant.  
• Fold over the Karmaplus Acoustic Perimeter Strip and trap it underneath the skirting board to ensure it is not in contact with the chipboard.

Timber floor:

• Lay the Karmafloor Acoustic Battens around the floor perimeter, foam side down and leaving a 50mm gap from any wall.  If at any point a shorter batten length is required, cut to size.
• Lay the Acoustic Battens within the perimeter battens, staggering joints at 400mm centres if using 18mm chipboard and 600mm centres if using 22mm chipboard.
• Where a lightweight non load bearing partition is to be erected above the floating floor and runs perpendicular to the line of or directly above structural joists provide additional support by placing a double row of acoustic battens beneath the partition.  When the non loading partition is not supported by structural joists create a ladder frame by placing cut lengths of batten perpendicular to the 2 adjacent rows of battens at 400mm centres.
• Position the Karmaplus Acoustic Perimeter Strip around the floor perimeter.
• Install acoustic quilt in between battens.
• In a brick bonded method, lay the plank on the battens, ensuring the joints are staggered, short edges are resting on a batten and leave a 10mm gap at the floor perimeter.
• Screw the plank to the acoustic battens using four drywall screws across the face, two 25mm in from each edge and two equidistant in between.
• Leaving a 10mm gap at the perimeter, lay the chipboard in the same direction as the plank, ensuring the plank joints are staggered from the chipboard joints.  Spot bond chipboard to the plank and ensure the short edges of chipboard rest above a batten.
• Screw the chipboard to the battens through the plank using four countersunk screws across the face, two 25mm in from each edge and two equidistant in between.
• Glue continuously along the tongued and grooved joints, removing excess glue with a damp cloth.  All joints must be tightly butted.
• Seal any gaps in the floating floor with acoustic sealant.
• Fold over the Karmaplus Acoustic Perimeter Strip and trap it underneath the skirting board to ensure it is not in contact with the chipboard.
