Heat pumps, pumps and similar vibrating devices should be innately decoupled well from the floor so that the vibrations do not spread through the floor (structure-borne sound). The manufacturer usually pays attention to this during the installation. If not, you can use our foam rubber to decouple the pump or devices in general from the floor. The emitted airborne sound must then be absorbed.
For an attenuation of the noise, you must enclose the device, thus build a type of room around the heat pump and line this with a 5 cm thick foam - if the area is dry, our acoustic foam planes or our rebond foams are most suitable. The thicker, the better the insulation. To maximise the insulation, you can also build a triple construct - first, a rebond foam sheet is adhered, then our double-sided adhesive bituminous foil and on that another rebond foam sheet.
You will find more detailed information on how this construction works in the Help topic area under “outward noise insulation”.
If the heat pump is outdoors or in an area which is damp or wet, then foams are unsuitable because they absorb water and disintegrate. You should also enclose heat pumps outdoors and then proceed as described above. The thicker you choose the foam, the better the insulation is in turn.
However, most pumps have to be ventilated also. Naturally, this cannot be combined directly with noise insulation. Thus you have to build a type of ventilation duct too and line this also with foams so that air can be extracted or discharged. Ideally, you should interlace the duct so that the sound cannot be emitted directly.

Fire protection is an important issue when installing acoustic foam sheets.
The quality of the acoustic foam is largely responsible for its absorption behaviour.
Noise insulation is much more complicated than pure acoustic improvement or resonance removal.
You can easily mount foam because it is very light compared to other materials
