Suitable material for noise protection measures

There are many ways to keep annoying noise out of the apartment. Effective measures are insulation on surfaces and leaks. For really effective, self-installed insulation constructions, it is essential to follow a few rules - this includes using the right materials.

Correct noise protection materials depending on the measure

The materials you need for effective noise protection naturally depend on the measure you are aiming for. However, there are also some basic rules for the soundproofing effect of material:

  • massive, i.e. dense, heavy materials insulate well
  • stiff materials insulate sound worse
  • flexible materials are used to compensate for vibrations

Materials for ceiling and wall insulation

Regardless of whether you want to insulate a room ceiling or a wall against noise, the process is basically the same: first, an insulation layer is applied and in front of it one or even better two cladding is placed.

Because the mass of a material determines its sound insulation performance, you should use materials that are as dense as possible for the insulation layer. For example:

  • Rock wool (29.80 € at Amazon *)
  • Wood fiber
  • Polystyrene
  • Glass wool
  • cellulose

Rigid foams such as Styrofoam are less suitable for sound insulation because of their open-pored structure, but are well suited for cold insulation.

It is best to use building boards made of solid material such as plasterboard or wood for the cladding. With two instead of just one facing layer, you can achieve an even better noise protection effect. However, so that the plates can vibrate independently of one another and do not pass frequencies on to one another, they must be placed at a sufficient distance from one another.

The decoupling of the individual components from the existing building fabric and from each other is also crucial for the effectiveness of the installation. Attachment profiles for the insulation layer must therefore be attached with spacers made of elastic material such as rubber, felt or mineral wool and not directly on the ceiling / wall. Pre-cladding must also be decoupled by compensating elements such as adjustable swing bars.

Materials for door and window insulation

To keep noise out of the stairwell, for example, you can insulate the surface of the apartment door. This works best with foam or mineral wool mats and decorative wall sheeting or with finished door cushions.

For gaps under the door or non-flush window closings, you can use simple insulation strips made of rubber or draft strips made of thermoplastic elastomer (TPE).

Windows and doors can also be made more soundproof with an acoustic curtain. This can also be a solution for dividing an office area within a room. With acoustic curtains, make sure that you use a high-quality molton material.
