Servers & server rooms

Effective noise protection for servers and server rooms

The noise generated by servers, computers and other electronic devices—particularly by fans, hard drives or power supplies—can be perceived as disruptive both in the workplace and at home. These noise emissions are often in the mid to high frequency range and can impair both concentration and general well-being. To reduce this impact, special sound and thermal insulation materials are used, which can be installed both directly on the equipment and throughout the entire room.

We are happy to assist you in selecting suitable materials and offer bespoke solutions – tailored to your requirements and spatial conditions.

Direct noise insulation on servers and computers

Direct noise insulation for servers and computers Various materials that are acoustically effective and thermally resistant are suitable for noise reduction directly on the device. The following are particularly suitable:

Melamine resin foams (Basotect® G+), which offer excellent sound absorption due to their open-cell structure whilst meeting the strict fire safety requirements (BKZ of VKF 5.2). They are available in various surface finishes (e.g. dimpled, smooth, laminated).
Recycled PUR foams, as well as combined solutions such as Teroform® composite mats, which consist of PUR foam and heavy-duty plastic layers. These offer high mechanical stability and effective insulation in a compact design.
Heavy-duty sheets (Teroform® and Terodem®) based on plastic or bitumen, which are ideal for reducing structure-borne noise. They are often combined with foam materials to further enhance sound insulation.

Depending on the available space, these materials can be installed inside the housing or used for external encapsulation. Care must be taken to ensure adequate ventilation so as not to increase the thermal load on the components. Air ducts or temperature-resistant, breathable insulation materials help to prevent heat build-up.

Room acoustic optimisation in server rooms

In larger data centres or technical facilities, it is advisable to specifically enhance the room acoustics in order to comprehensively dampen noise sources. In addition to wall and ceiling absorbers, floor insulation and, above all, retrofitted door insulation are also used here. Frequently used materials include:

Polyester fibre fleece (Fiberform) – durable, dimensionally stable, moisture-resistant, easily recyclable and versatile.
Composite foams (Teroform®Kombi) – very high density and mass, resulting in excellent sound insulation, but only limited flame retardancy.
Melamine foam (Basotect G+) – high fire resistance class, particularly suitable for sensitive environments with increased safety requirements.

A holistic approach also includes the decoupling of sound bridges, for example through elastic mountings, damping floor mats or acoustically isolated enclosures. All materials used should comply with the relevant fire safety regulations – particularly in areas with high electrical loads. Even where there are no legal requirements, the use of flame-retardant materials is generally recommended.

Noise protection in server environments can be effectively implemented through the targeted combination of absorptive, damping and decoupling materials. In addition to acoustic performance, criteria such as fire safety, thermal resistance, installation options and indoor climate are decisive factors in the choice of materials. Whether it’s localised insulation on equipment or room acoustic optimisation – the right solution ensures greater peace and quiet, safety and efficiency in technical environments.
