Isolmant has been promoting the concept of the “Sistema Pavimento”, which is the italian for "Floor System", for years, based on the idea that the system-based approach should be the foundation of any construction consideration, both in new builds and renovations.
When it comes to acoustic insulation, the “Floor System” refers to a structure in which each element must be aware of the others, and all components must work together in synergy to achieve optimal performance.
In this system, the insulating material—whether placed beneath the screed (under-screed solutions) or under the floor finish (underfloor solutions)—plays a central role in meeting the client’s expectations. These expectations go beyond simply complying with legal requirements and focus instead on ensuring a truly comfortable living environment.
The Floor System is designed as an integrated technological system that, with a view to sustainability, balances acoustic, thermal, mechanical, and aesthetic needs, along with requirements for service integration and long-term durability.
When the insulation is placed beneath the screed, we are generally dealing with a “designed” solution, whether for a new build or a renovation project.
The acoustic insulation is installed below the screed, and the structural characteristics are defined based on the thickness of the screed itself.
When the insulation goes beneath the flooring, we are operating in an evolving context, where needs and requirements can vary greatly. In this scenario, the choice of insulation becomes crucial for defining the acoustic and mechanical performance of the floor and must and must follow a system approach.
Impact noise, also known as footfall noise, refers to the collection of sounds generated by shocks, impacts, and mechanical stresses within a building. Most impact noises affect horizontal partitions, as they are structurally transmitted and typically caused by footsteps, falling objects, or dragged items.
The solution to reduce the transmission of impact noise is the construction of a technological assembly made up of layers of materials with different physical and mechanical properties, capable of dissipating the energy caused by impacts. Specifically, the construction technique of the floating screed system involves decoupling the screed and flooring from the adjacent structures by means of a layer of elastic material placed beneath the screed that supports the flooring and along the perimeter of the room. By interposing this resilient layer, a “container” or “basin” is created in which the screed is free to float, not rigidly connected to the surrounding structures. This creates an oscillating system that absorbs and dissipates the sound energy generated by impact.
