Soundproofing & Vibration Insulation for Appliances & Machines

Soundproofing and insulation for appliances and machines
Appliances and machines, such as a pump installation for an aquarium, or a swimming pool, noisy compressors, air conditioning units or a washing machine, can all produce unwanted noise and/or vibrations which undesirable for the surroundings. Most of these appliances, devices or machine causes sound problems because they switch on and off at the most undesirable times. Leaving the direct surrounding area with airborne noise and/or contact noise. On this page we offer soundproofing and insulation products and solutions for both sound problems Which solutions and product you choose, always pay close attention to the ventilation of the appliances you want to soundproof!

Soundproofing and insulation for airborne noise
To insulate airborne noise from appliances and machines it's necessary to place a housing, or enclosure, over the a device. This housing must meet three important requirements: mass, decoupling and ventilation. A good housing is made from heavy sheet material, for example plywood insulated with Isomat TS. Mass = Insulation. This means that a housing or enclosure made of heavy plywood will give the best result, lightweight enclosures cannot insulate low frequencies or loud sounds.

When you make a soundproof machine housing, make sure it's spacious enough, leaving enough space for the machine and an acoustic sound insulation product. The properties of the sound insulation products, such as heat-resistance, depends on the situation and machine in question. We recommend a product with a protective top layer as thick as possible for the best result.

Insulation to reduce impact noise
Vibrations from appliances are reduced by isolating them from their foundation. You can do this with Regufoam vibration insulation which isolates the source from it's foundation. It's not necessary to equip the entire floor area underneath the appliance with Regufoam. For non-industrial appliances and machines, a few parts, or feet, made of Regufoam measuring 120 x 120 x 25 mm is usually sufficient enough.

The amount of Regufoam parts and the density needed all depends on the weight and size of the device. Regufoam with a thickness of 12 mm is often used for machines with a high centre of gravity and high RPM's, such as a turning lathe or washing machine. Machines or equipment with a vertical movement, like a treadmill or with the same form of movement, is best placed on a Regufoam type with a thickness of 25 mm, or even double, 50 mm.

Sound insulation products
To soundproof and insulate machine noise, and thereby machine enclosures, you can use an acoustic sound insulation, or sound absorber product, without a protective top layer, such as Acousticcell, for clean and dry appliances. For machines and devices that leak moisture or oil we recommend using a sound insulation woth top layer such as Merfocell PU or Flamex PU. With the latter it's important to tape the seams with PU Finishing Tape. Use Flamex FC for appliances that produce high temperatures up to 150°C.

Industrial equipment and complex machines
In some cases it's better to make a calculation to find out the appropriate way to soundproof or insulate appliances or machines. Please do not hesitate to contact us for advice on how to proceed. On our tips page you can a guide on how to make a housing, or enclosure, for appliances and machines.
