Why is floor sound insulation important?

Footsteps, furniture moving and impact noise from above transmit to the lower floor as structural vibration, not as airborne sound. So even with wall and ceiling insulation, upstairs noise persists if the floor is left untouched. Floor sound insulation places an elastic layer between the screed and structural slab, breaking the path of structural vibration.

Which product types are available?

• Rubber sheet (5-25 mm): high impact resistance, ideal for heavy traffic
• Cork mat (3-10 mm): natural material, classic under-parquet choice
• Acoustic mat (5-20 mm): polyester or foam-based, broad use
• Carpet tile (raised floor): acoustic-backed carpet for office and modular floors
• Floating floor systems: rubber + cork combination, top performance
• Under-parquet acoustic membrane: fast install, thin profile

Where is it used?

• Apartment upper-lower floor sound insulation
• Hotel room floor acoustics
• Office between-floor
• Fitness room, dance / pilates studio
• Hospital and clinic corridors
• Concert hall / stage
• Data centre raised-floor system

How does floating screed work?

Floating screed is a screed layer fully decoupled from the walls and substructure. Acoustic mat is laid; 50-80 mm concrete screed is poured on top; resilient edge tape is applied to walls. As the screed "floats", impact vibration does not travel into the structure. In our practice, floating screed alone delivers 22-28 dB impact-noise reduction.

How to choose the right product?

1. Load: 5-10 mm enough for residential; 15-25 mm needed for fitness.
2. Target reduction: ΔLw 22 dB minimum is acceptable for apartments.
3. Build-height limit: if thin profile is mandatory, use a high-performance formula.
4. Humidity / temperature: use suitable material for bathrooms, kitchens, outdoors.
