Theoretically, the base coat is designed to last up to 25 years or more. The general rule is that if the finished floor would normally be installed loose, the base layer can also be installed loose. But always check with your base and flooring supplier. 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.
This is because not all underlays are created the same way, so you can't assume that one 5 mm underlay will perform the same as another. The MuteMat 3 is the best acoustic base that allows you to comply with the construction regulations of part E without the need to use any other material. The only function of the acoustic floor base is to reduce the amount of impact noise that travels through the floor due to falling objects, footsteps and the movement of furniture on the hard surface finishes of any type of building. This combination of acoustic underlays allows you to achieve much better results with thinner soundproofing products.
Seal tightly against the wall: place the acoustic base against the wall, place a washer on the mat and use the inside of the washing machine to draw a line along the carpet by dragging the washer along the wall to get an exact replica of the shape and curve of the wall. This, together with the MuteMat range, provides the combination of highest-performing acoustic bases and, at the same time, keeps the build-up as thin as possible. Factors such as foot traffic, exposure to moisture and the type of floor installed can affect the useful life of the base layer, so it is essential to consider living conditions and specific preferences when choosing between the best base options. If the base is badly damaged, it is best to replace it with a new one to maintain the comfort and longevity of the carpet.
In these situations, it is almost always necessary to use an acoustic base for floors to meet these standards. In the case of carpets, you need a product that is soft but doesn't hit rock bottom, as is the case with most acoustic base coats on the market. While many of the advantages of the subfloor include compressive strength, thermal insulation and the ability to level the subfloor, one of the most important advantages is the reduction of noise thanks to its excellent acoustic properties. The base layer (with floor covering) must be acoustically tested to show how much impact noise it reduces.
Acoustic subfloors (for hard surface floors) and carpet cushions (for soft surface floors) are essential to meet these strict codes. However, in other places, there are no requirements or local legislation, making it a pleasure to have an acoustic base for floors.
