Installation instructions for impact sound insulation rolls

Variant: DIY instructions

1. Preparation & placing of the rolls

Observe the official laying instructions provided in every package before laying the rolls, otherwise any warranty or guarantee claim will be invalid.

The subsurface should be firm, level, dry, and dust-free before laying. Before placing, thoroughly vacuum the subfloor. Store the insulating mat in the room for about 24 hours before installing it to allow the material to adapt. As soon as the substrate has been checked, the first sheet can be laid out in a well-positioned spot in the opposite direction of the top floor covering. Simply cut the first mesh from the roll using a cutting knife to separate it from the roll. When installing parquet, the rough side is laid down. When placing vinyl, the rough side should be up. A cutting knife can easily separate the mesh. To avoid overlap, the succeeding lanes are now placed end to end on the ones already in place.

ATTENTION: Please note that the edge distances of about 5 mm from the wall should be maintained.

2. Fix panels

To prevent the footfall sound insulation strips from slipping while paving the floor, secure them at the abutting edges using aluminium tape. Check that the strips do not overlap. There should be places of contact only at the abutting edges. You can now begin to install the floor.
