Insulating floors is becoming increasingly important in construction. Where carpets were used extensively in the past, this is now less common. As a result, more hard floors, such as wooden floors or concrete slabs, are being installed. Hard floors generally have more issues with impact noise, such as footsteps. Therefore, it is beneficial both for the user and for neighbours below to add a good sound-insulating layer.
Would you like to reduce sound transmission from your floor? Then it is important to first determine what type of subfloor you have. In this article, we explain step by step how to effectively insulate a wooden subfloor against noise.
Want to reduce sound transmission through a concrete floor? In this article, we explain step by step which construction effectively insulates sound with a concrete subfloor.
Floor insulation is generally relevant for all buildings with multiple floors. In apartments, it is essential for the comfort of the residents below. In commercial buildings, such as offices or schools, it helps to reduce sound transfer between floors - which benefits concentration and productivity.
When isolating floor noise, we distinguish between two types of sound:
Contact sound: arises from direct contact with the floor, such as walking or dropping something.
Air noise: arises from vibrations in the air, for example in speech or music.
Contact noise is effectively dampened with resilient materials that absorb vibrations before they spread through the construction. A floating screed is a suitable solution for this. To isolate airborne noise, a combination of extra mass and a floating floor or installing a soundproof ceiling in the underlying room is an effective approach.
The best soundproofing solution depends on the type of floor construction. A wooden floor requires a different approach than a concrete floor. On the underlying pages, you will find more information and suitable solutions for each type of floor. Wooden floor insulation Concrete floor insulation
