Nur 8 mm dünn – trotzdem 28 dB Trittschallschutz?

Impact sound insulation in existing buildings often fails due to the installation height. At just 8 mm thick, the BTF Whisper Mat reduces impact sound by a tested 28 dB – and is also compatible with underfloor heating. ... What you'll learn in this video: Why the installation height in existing buildings determines whether a project is feasible or not How the whisper mat achieves a tested 28 dB impact sound reduction with just 8 mm of insulation How to retrofit underfloor heating without violating DIN 4109 🔧 Product used: BTF Whisper Mat – 8 mm impact sound insulation for renovations, tested according to DIN ISO 10140, certified by ETA 22 0600 🔗 More information about the whisper mat: https://www.btf-innovationen.de/btf-f... 🔗 To the blog post: https://www.btf-innovationen.de/tritt... --- How do I permanently stop impact noise in existing buildings without losing installation height? In renovation projects, the installation height is often the limiting factor around doors, thresholds, and heating connections. The BTF Whisper Mat was developed precisely for these situations: With a thickness of just 8 mm, it achieves a tested ΔLw value of 28 decibels according to DIN ISO 10140, secured by the European Technical Assessment (ETA). It can be combined with thin-layer screed systems and underfloor heating, thus simultaneously meeting the requirements of DIN 4109. Load-bearing capacity is up to 4 kg/m² (standard) or 10 kg/m² (heavy-duty version) – more than sufficient for typical residential construction. In short: 8 mm installation height, 28 dB tested impact sound reduction, ETA-certified – a planned detail instead of a compromise solution.
