Avoid structure-borne noise in buildings
Heat pumps, ventilation units and chillers often run around the clock. Without decoupling, their vibration travels through plinths, roofs or ceilings into the building as a low-frequency hum.
Quiet buildings
Elastic bearings prevent vibration from reaching living and working spaces.
Weatherproof
EPDM-based mats resist weather, ozone and UV – ideal for roofs and outdoor use.
Easy installation
Simply place mats and pads under plinths, brackets or base frames.
Typical applications
- Air-to-water heat pumps (indoor and outdoor units)
- Ventilation and air-handling units
- Rooftop dry coolers and chillers
- Heating and circulation pumps
- Emergency generators and CHP units
Recommended systems & technical data
| Recommended system | Load range (static continuous) | Suitable for |
|---|---|---|
| PUR elastomer, very light to medium | 0.011 – 0.22 N/mm² | Heat pumps, HVAC units – natural frequencies down to approx. 8–9 Hz |
| PU-bonded rubber granulate/fibre mat, class G1–G3 | 0.02 – 0.10 N/mm² | Plant rooms, screed decoupling, plinths |
| EPDM pads and strips | to design | Permanent outdoor installation |
Indicative values for static continuous load. Final design is project-specific.
FAQ
Will a mat help against heat pump hum?
If the noise is transmitted as structure-borne sound via plinth or wall, a properly designed decoupling is one of the most effective measures.
Are the mats suitable outdoors?
Yes – for outdoor use we recommend EPDM, which resists weather, ozone and UV.
Is your building services equipment causing noise?
Describe your installation – we will find the right decoupling for your building.
