  • Lay the battens in continuous rows at recommended centers, with the felt side down. Leave a 25mm gap between the perimeter battens and the walls.
  • If using SilentCloud-Felt™ 10 Resilient Layer, roll it out across the base structure before laying the battens, ensuring full coverage.
  • Plan the floor layout with a 10-15mm expansion gap around the perimeters. Fix the flooring boards to the battens using SilentCloud-Bond Panel Adhesive and secure with ring nails or screws. Avoid penetrating the resilient layer. Glue the flooring boards at all teegee joints.
  • Use SilentCloud-Seal 20 Perimeter Seal to fill the expansion gap, ensuring acoustic isolation from the walls. Alternatively, follow Robust Detail instructions using SilentCloud-RD Flanking Strip.
