The base (with floor covering) must be acoustically tested to show how much impact noise it reduces. This is because not all underlying layers are created the same way, and not all underlays are created the same either. Therefore, you can't assume that one 5 mm underlay will perform the same as another. The acoustic subfloor for vinyl floors must have the necessary dimensional stability to avoid crevices and the thickness necessary to absorb sound. In general terms, felt, cork or foam would be good acoustic underlayment options.
Rubber, while it might work functionally, is known to dye vinyl and is not recommended. The Hush II, composed of cork and foam, is a good example of a patented underlayment system designed for luxury vinyl tile (LVT). When combined with compatible stretch flooring products, this system can reach between 50 and 70 IIC. The reduction of floor noise is achieved mainly through the use of an acoustic base. Installers must place rolls or sheets of subfloor above the subfloor before installing floating boards on top.
Think of the base layer as a layer of foam or rubber material that cushions any impact and blocks loud noises. The INS Soundsense acoustic base has several advantages, as it offers sound reduction and thermal insulation. Our acoustic floor base can also offer great durability and resilience, and adapts to any property that requires a high-performance base layer. Acoustic floors generally inhibit the transmission of two forms of noise, such as impact noise and airborne sound. The additional advantage is the reduction of noise transmission within the building structure.
For example, FloorVenue has a Marvel SPC hybrid floor, which comes pre-installed with a 6-star acoustic base. Marvel hybrid floors can be installed almost anywhere, as they have the highest acoustic certification without the need for an additional base layer. As an acoustic membrane, the Inspira Sound acoustic layer is perfect for any concrete floor, as it prevents echoes, but it also ensures that more use is made of the floor before it starts to show signs of wear and tear. However, in other places, there are no requirements or local legislation, so it's a good idea to have an acoustic base for floors. The performance of an acoustic base layer depends on several factors, such as the thickness and density of the material, as well as the type of floor being installed. If you are looking to improve the acoustics of your property, the INS Soundsense elastic acoustic layer is ideal. If your concrete walls produce an echo, this acoustic base will remove any tension and instantly make your home feel cozier.
Acoustic subfloors (for hard surface floors) and carpet cushions (for soft surface floors) are essential to meet these strict codes. The main function of an acoustic floor base is to reduce the transmission of noise through the floor, absorbing or blocking sound waves and vibrations. You can work with your flooring contractor to choose the acoustic paving system, including the floor itself, its subfloor and the installation accessories that best meet the specific needs of your application. The purpose of the acoustic base for floors is to prevent the transfer of excessive volumes, but also to provide a protective layer for the floor.
