Underlayment options provide different performance attributes, such as better moisture tolerance or sound absorption. When selecting a floor material, it is important to follow the manufacturer's recommendations for adhesives and underlayment to ensure the warranty remains valid. Depending on the product, you may be able to choose from several manufacturer's underlayment options that offer different performance characteristics, such as better moisture tolerance or sound absorption. In addition to soundproofing, acoustic underlayment also has moisture-resistant qualities that protect the subfloor from early decay.
As the name suggests, acoustic underlayment is specifically designed for soundproofing and can be very effective, although it is more expensive than most other soundproofing materials. There are acoustic underlayment options for all types of floors, including rubber underlayment for tiles, cushions for carpets and cork for wood. If sound insulation is a major concern, opt for a subfloor with superior acoustic properties. The most common reason for installing an acoustic base is its ability to reduce noise levels and vibrations caused by footsteps.
Acoustic subfloors (for hard surface floors) and carpet cushions (for soft surface floors) are essential to meet these strict codes. If sound reduction is essential to your project, consider selecting a specifically designed underfloor to provide acoustic performance. These lower layers may be more expensive than foam or rubber options, but they offer superior acoustic performance. For those installing new floors in the house, consider placing acoustic layers first, especially if you are thinking of hardwood floors.
You can work with your flooring contractor to choose the acoustic floor system, including the floor itself, its subfloor, and installation accessories, that best meets the specific needs of your application. The acoustic underlayment for vinyl floors must have the necessary dimensional stability to prevent notches and thickness from absorbing sound. Polyurethane foam underlayment is the least expensive underlayment option and offers some insulation under new floors. The acoustic base, which often combines several layers of fluffy material, provides great comfort to family members when walking under their feet.
A good soundproofed underfloor will also block the noise generated by the structure in a similar way: the underfloor acts as a damper for noises transmitted by the structure, such as footsteps. Some LVP manufacturers may require specific underlayments or may not recommend the use of any underlayment. An acoustic underlayment made of cork, rubber or foam can further reduce noise and prevent its transmission. The acoustic subfloor must be installed under the structure (if necessary) on the upper floor and must completely cover the floor so that no paths form lower resistance.
