The ISOVER Acoustic Comfort Classes. Life is better without noise.

2 ISOVER ISOVER 3 All around the world, the general noise level is at an alarmingly high level. As you are exposed to this soundtrack of modern life day and night, you are bound to reach the limit of what you can stand rather quickly. Today, any kind of protection from noise definitely helps to improve our mental and physical well-being. It is a well-known fact that noise pollution not only makes relaxation more difficult. It also causes physical stress and even pain and thus poses a serious health threat. By offering appropriate insulation solutions for both new builds and renovation...

4 ISOVER ISOVER 5 On an island of silence: the whole potential of acoustic insulation. Successful protection against noise pollution calls for sophisticated and well-aimed measures. Although, e.g. in Austria, the sound insulation standard has always been high, a large part of the population feels disturbed by ambient noise – even at home. When conducting a scientific study on the topic, two things turned out: first, the applicable sound insulation standards were no longer up-todate; second, their implementation was often handled very carelessly. The regular revision of sound insulation...

6 ISOVER ISOVER 7 How to block out noise: the blueprint of acoustic comfort. Only sound insulation that has been planned for and integrated in the earliest blueprint stage can be expected to achieve maximum effect. In our endeavour to control noise, every detail counts that is able to influence the noise level in a positive way. Good planning takes many factors into account. In order to block out ambient noise, external walls, roof and windows need to be perfectly insulated. In addition, carefully designed internal walls, floors and ceilings block the DnT,w Speech Audibility Effectiveness...

10 ISOVER ISOVER 11 Enjoy the”Comfort“ class. Thanks to the mass -spring-mass principle. The mass-spring-mass system ensures top performance in the sound insulation of adjacent rooms by combining optimum acoustic protection Massive walls Sound Mass-spring-mass performance construction Thickness [mm] Surface weight Rw [dB] Surface weight Thickness [mm] [kg/m2] [kg/m2] 100 140 42 19 75 130 180 45 20 100 160 220 48 21 125 The soundproofing efficiency of mass-spring-mass systems is unique and vastly superior to single-leaf constructions. It is a well-known fact that in conventional solid...

12 ISOVER ISOVER 13 Why three walls absorb more sound than one. In the case of two-leaf walls, the sound-damping effect is achieved by the interplay of the individual components. This interplay determines the efficiency of the system as a whole. Compared to one-leaf walls, the possibilities of influencing the efficiency are much more diverse with two-leaf walls. The single components can be optimally matched to each other and to their respective environments. The acoustic effect of these positive factors adds up. This is where ISOVER lightweight insulating materials come into play. Their...

14 ISOVER ISOVER 15 When installing soundproofing materials, the density of the sound absorber within a mass-spring-mass system is not important. This is proven by ISOVER glass wool: on the one hand, it reduces sound much better than thinner materials that are more pervious to air. On the other hand, materials with a higher density (or air flow resistance) do not achieve any further improvement: such materials are stiffer and thus likely to form sound bridges. ISOVER glass wool is therefore an excellent "spring" material in combination with multiple plasterboard "masses": such wall systems...

16 ISOVER ISOVER 17 Solutions for excellent sound insulation: how to achieve the ”Comfort“ class. Soundproof inside the dwelling: damping internal walls. Keep noise out: horizontal sound insulation between living units. Recommended construction of a double metal stud partition. Recommended construction of a wood beam ceiling with a floating floor. Make floors and ceilings into sound absorbers between dwellings. Recommended construction 2 x plasterboard 12.5 mm 25 mm ISOVER glass wool 100 mm 2 x plasterboard 12.5 mm 25 mm Recommended construction 2 x plasterboard 12.5 mm 25 mm 2 x ISOVER...

18 ISOVER ISOVER 19 Insulating massive walls the light way. Roof constructions with top level damping. By significantly improving the insulation values of regular walls, you can achieve the “Comfort” class in renovation. Recommended construction Hollow brick wall 200 mm Mortar 15 mm ISOVER glass wool 100 mm ISOVER Optima System – Plasterboard 12.5 mm Get the best out of a brick wall: with metal framework and gypsum boards. Dry lining is the best solution when it comes to achieving better acoustic performance for existing walls in new buildings and renovation projects. Instead of increasing...

20 ISOVER ISOVER 21 ”Music“ class damping: the sounds of silence. Sometimes, the acoustic insulation of interior walls needs to meet particularly high demands, e.g. when soundproofing a private bedroom. In this case it is essential to avoid an often overlooked sound bridge: the stud between the gypsum boards can have an impact on the insulation performance. This effect may be diminished when using The task of soundproofing inside a building is to prevent the transmission of sound between rooms. However, the propagation of sound does not only take place between immediately adjoining rooms,...
