First-class sound dampening underlay with decoupling function, consisting of mineral fillers. Thanks to full gluing on both sides under parquet, Silent Double Fix achieves the best possible footfall sound values (+6 db compared to direct gluing on a cast floor without Silent Double Fix). Also suitable for floating laying and laying on top of underfloor heating.

The underlay can only be used for 3 layers of parquet, not 2 layers!
