Step 1: Apply a vibration-isolating layer
Lay a layer of vibration-isolating material, such as EASYbond, directly onto the concrete floor. This layer absorbs impact noise and prevents vibrations from spreading through the structure.
Step 2: Attach a edge strip along the walls
Place an edge strip of vibration-isolating material along all walls. This strip ensures that the floor structure does not make direct contact with the walls, preventing sound vibrations from propagating through the construction to the walls.
Step 3: Attach OSB or underlayment boards to the insulation layer
Install OSB or underlayment boards on top of the vibration-isolating material. Using planks with a tongue-and-groove connection usually requires only one layer. If standard straight boards are used or if the floor is heavily loaded, it is advisable to place two layers in a staggered pattern. Ensure that the boards do not directly abut the wall but connect to the insulating edge strip.
Step 4: Choose a suitable finish
Finish the floor with a coating of your choice, such as laminate or PVC. Make sure the finished floor remains clear of the wall and connects to the insulating strip along the edges. This prevents impact noise from still being transmitted via the walls.
