Floor Soundproofing – Complete Guide & Certified Solutions
Introduction
Floor soundproofing is essential for protecting against impact noises (footsteps, knocks, falling objects) as well as vibrations transmitted through the structure. In apartment buildings, hotels, recording studios, or commercial spaces, proper sound insulation ensures:
✔️ Comfort & privacy for users
✔️ Compliance with regulations and specifications
✔️ Prevention of complaints & technical failures
Stop Sound Constructions provides certified floor soundproofing systems with lab-tested and real-project verified results.
Types of Floor Soundproofing
1. Floating Screed Floors
The most common and effective solution for demanding projects.
- Installation of a floating concrete screed on a vibration isolation underlay
- Excellent isolation at low frequencies
- High load resistance and mechanical stability
- Compatible with underfloor heating systems
Materials we use:
- ISOLMER® & ISOLDYN® (mixed-cell polyurethane)
- Recycled rubber underlays
- Closed-cell polyethylene
- Composite multilayer systems

5. Perimetric Decoupling & Sound Bridge Prevention
No soundproofing system performs effectively without proper perimetric decoupling.
With products such as:
- Superfascia AD®
- ISOLMER®
we ensure complete separation of structural elements, eliminating sound bridges that reduce the system’s overall acoustic performance.

Common Mistakes in Floor Soundproofing
- Using only a thin underlay without a membrane or decoupling layer
- Discontinuous installation of perimeter tape → formation of sound bridges
- Incorrect material selection in areas with high loads
Stop Sound Case Studies
🏨 5-star Hotel in Athens: installation of floating screed with ISOLMER® → impact noise reduction > 28 dB

Frequently Asked Questions (FAQ)
Q: How many dB can floor soundproofing reduce?
A: A certified floating floor system can reduce impact noise by more than 35 dB.
Q: What is the cost?
A: The cost depends on the floor type, underlay, and project requirements. There are economical to premium solutions available.
Q: Can it be applied in renovations?
A: Yes. With thin underlays and Viscolam® membranes, sound insulation can be significantly improved without major structural interventions.
