Sound insulation is always more effective with multiple layers
Currently, when carrying out the final procedures, the latest technologies and highly effective materials are used, capable of handling tasks of any complexity at a high level. It is important to remember that in order for apartment soundproofing to fully meet all expectations, it should be done at the stage of major renovation. This applies both to new buildings and to secondary housing stock. Unfortunately, modern construction organizations do not pay due attention to the soundproofing of each individual apartment. As a result, those citizens who want to protect themselves and their loved ones from hallway noise and extraneous sounds coming from neighboring apartments have to do it on their own.
First, you should carefully inspect the walls for cracks and poorly sealed entries of heating pipes, hot and cold water supplies, etc. After that, small cracks are puttied, and large ones are foamed. In addition, complete plastering of the walls is carried out. Such measures can significantly improve the soundproofing of the apartment. In addition, there are additional measures that are carried out using the latest technologies and modern materials.
It is important to remember here that sound insulation is always more effective with several, even thin, layers than with one. Therefore, a good option could be to create a multi-layer wall structure. Among the relevant ones is a backing made of foamed polyethylene, which is installed directly under the wallpaper on a pre-leveled surface. This method allows to additionally improve the parameters of thermal and waterproofing.
Another option is the use of mineral materials. It is important to remember that such constructions 'eat up' about 8 cm around the entire perimeter, since there is a need to cover the sound insulation with plasterboard sheets. Thus, this method is relevant for those rooms that have sufficient area.
