Floating Floor Solutions
Impact noise is caused by the use of rooms, radiating via the floor into adjacent rooms and other floors of the building. Effective floating floor solutions isolate the source elastically from the structure — stopping noise where it starts rather than treating it after it has spread.
This is essential in mixed-use buildings: supermarkets beneath offices, doctor's surgeries next to private apartments, rooftop bars above hotel suites, and recording studios in any building type. The right approach depends on load, available floor height, construction type, and the frequency range of the primary disturbance.
The Acoustic Floor Mat (AFM) range is installed over the entire surface and is suitable for isolating floating screed, dry screed, and heavy-duty screed. Six types provide customised sound control — from targeted compliance with standards to the highest acoustic requirements, with impact noise improvements of up to 38 dB.
Product Features

Acoustic Floor Blocks (AFB) are elastomer point bearings made from Sylomer® material, used under dry and wet screeds. Due to their dynamic properties they achieve particularly low natural frequencies — indispensable in recording studios, cinemas, theatres, and stage construction worldwide.
Key Advantages
- Excellent impact sound insulation for high acoustic requirements
- Outstanding resistance to shock and impact
- Minimal settlement behaviour
- Exceptional long-term ageing resistance
- Natural frequency ≥ 6 Hz across all variants
- Compatible with FloorCalc® for customised calculations
Product Specifications

|---|---|---|---|---|
| AFB 30 | 30 kg/m² | 31 dB | 38 dB | 50mm |
| AFB 60 | 60 kg/m² | 31 dB | 38 dB | 50mm |
| AFB 110 | 110 kg/m² | 31 dB | 38 dB | 50mm |

The Akustik + Sylomer® Floor Mount is a point-bearing isolation element for floating floor construction. Each mount houses a pre-selected Sylomer® pad within a galvanised steel cup, placed under structural supports such as C-profiles or timber battens. Five variants cover loads from 25 to 100 kg/m², with the Sylomer® grade factory-matched to the specified floor load.
Key Advantages
- Factory-calibrated Sylomer® grade ensures optimal deflection at the design load
- Galvanised steel housing protects the elastomer during wet screed installation
- Compact, low-profile element — minimal impact on finished floor height
- Simple installation under standard C-profile or timber batten grid systems
- Suited to both new-build and refurbishment projects
Product Range
- Floor Mount 25 — 25 kg/m² · very light screed and panel systems
- Floor Mount 30 — 30 kg/m² · light anhydrite or gypsum screed
- Floor Mount 40 — 40 kg/m² · standard sand-cement screed · most commonly specified
- Floor Mount 75 — 75 kg/m² · reinforced or fibre-reinforced screed
- Floor Mount 100 — 100 kg/m² · maximum load in the range
The Akustik Floor Spring AFS combines a calibrated coil spring with a Sylomer® microcellular polyurethane element in a single point mount. The two elements work in series: the spring handles low-frequency isolation where elastomer is less effective, and the Sylomer® attenuates mid and high frequencies where springs alone perform poorly. The combined system achieves broadband attenuation not available from either material individually.
When to Specify AFS Over AFM or AFB
- Floors above mechanical plant rooms where both low-frequency machine vibration and higher-frequency impact noise must be controlled simultaneously
- Recording studios and broadcast facilities requiring the lowest achievable noise floor — where AFB blocks alone do not provide sufficient low-frequency attenuation
- High-specification residential and hotel floors above heavy vibration sources
- Any project where the disturbing frequency range spans both low-frequency mechanical excitation and mid-frequency impact noise
