Where can I buy heroal soundproof windows?

A professional installation is essential for your windows to provide the required sound insulation. heroal soundproof windows are exclusively available from heroal specialist partners. The windows are manufactured individually for you and adapted to every installation situation.

When do I need which sound insulation class?

However, the required sound insulation for a window also depends on the respective function of the living space. The following values can be used for orientation. During rush hours, the noise level should not exceed 25 dB in a bedroom, when the windows are open, 35 dB in a living room and 35 to 50 dB in a study. When it is time to start making plans for the installation of acoustic windows, the required soundproofing class should be determined in advance with a measuring device. A measurement is best made when the noise level is at its highest. If the noise reaches a value of less than 25 dB in the bedroom, a simple class 1 soundproof window with a sound insulation value of 25 - 29 dB is sufficient. However, if you measure a value of 43 dB, for example, you should opt for a class 4 soundproof window, which provides a sound insulation value of around 40 to 44 dB.

When are soundproof windows needed?

Ongoing noise is not only irritating, it can also affect your health. For adults, ongoing noise can have an impact on the cardiovascular system. For children, an ongoing high noise level has a significant impact on brain performance. Especially for people who live in a big city, on a busy road or near an airport, it is advisable to protect yourself against noise with acoustic windows. There are no general rules for the volume level that makes an soundproof window necessary. Noise is perceived subjectively, and each person feels a slightly different noise level to be disturbing. In general, however, a level of 55 decibels (dB) or higher makes it difficult to concentrate. Starting at 65-70 dB, there is an increased cardiovascular risk; and starting at 85 dB permanent hearing damage can occur.
