What's the problem? In and of themselves, concrete floors generally insulate air and contact noise well. In some cases, for example with constructions that contain large spans or hollow floors, both types of sound can still be heard. Contact noise is especially a problem in flats, think of sounds resulting from the ticking of high heels, slamming doors and walking up and down the stairs. Contact noise is ideally addressed at the source, its root cause. This does not necessarily apply to airborne noise, which can be reduced both at the source and the receiving side.
What is the solution to contact noise? The insulation of contact sound is done by applying a 'floating' floor. Akoestifloor is a product that allows you to create a floating floor. Akoestifloor consists of a layer of vibration insulation glued to a double layer of gypsum fibreboard with two sides that overlap. A floating floor reduces the amount of vibration that is transmitted to the existing floor. An important point to pay attention to is that the Akoestifloor shouldn't touch the walls! Use Agglomer Strips in order to achieve this. When selecting your product, pay attention to the total thickness of the floor including the floor covering, so that the doors can still open and close.
What is the solution to airborne noise? Air noise is usually not a problem in case of concrete floors. It is more likely that flanking sound will enter your room, i.e. through the walls, ventilation ducts or sound leaks such as not properly connected walls or ceilings. With high noise levels from a (pop) rehearsal room or studio, airborne noise may cause a problem. In this case we recommend you to combine Akoestifloor with the floating wall and ceiling system Merfoflex.
