Introduction
                                                                                                                           Benefits of Drywalling




Benefits of drywalling                                                                       Less weight, more upward scope
Modern Knauf drywall systems offer huge benefits compared to solid                           But it is not just in terms of surface area, their is also additional
constructions, for example, with regard to sound insulation, space gains and                 scope in the upward direction. Thanks to the considerably lower
lower weights.                                                                               weight, a vertical extension can be realised from a structural
            Sound insulation that sets the standard                                          point of view using drywalling. For even more space. And
            According to the German Federal Environment Agency (UBA)                         revenues.
            more than 40 % of people are disturbed by environmental noise.                   Lower loads on the foundation and thus lower initial costs.
            Just 10 dB more will be perceived as twice as loud.                  Furthermore, drywalling offers even more solutions.
            Nowadays, thick masonry is not a requirement to ensure                          Short construction time
            effective insulation from noise. By exploiting the spring-mass                  By tailor-made constructions and simple installation.
            principle, modern drywalling systems can significantly reduce the         fast
            noise from the room in other rooms.
                                                                                             Room climate
            Furthermore, intelligent constructions avoid sound bridges with
                                                                                             Sustainable climate management as a comfort and health
            the floor and thus a transfer of footfall noise.                       indoor
                                                                                   climate   factor.
            Knauf drywalling also has an ace up its sleeve when to comes
            to remodelling in solid construction: By installing furring on the               Flexibility
            exterior walls the sound insulation is improved considerably.                    Quick retrofitting and upgrading for a customized room design.


            Every centimetre counts
            Slim construction that offers a huge plus in terms of net surface
   +m2      area. When employing Knauf drywalling systems this can be as
            much as three percent in comparison to solid construction.

Cladding with Silentboard GKF in comparison to Knauf Wallboard GKB
Flexurally ductile even with its high mass
Knauf Silentboard achieves exceptional sound insulation properties due to its modified gypsum core. With Silentboard, the weight of the cladding can be
increased significantly without using thicker and thus more rigid boards. Accordingly, the important flexurally ductile behaviour for sound insulation is retained.
The high weight facilitates a reduction in the wall thickness or enhancement of the sound insulation.

             If divergent wall constructions are to be upgraded with the measures described here, the listed sound reduction improvement measures may
