what to put under vinyl flooring

Underlayment is not always necessary for vinyl flooring, but it can provide benefits such as sound reduction, insulation, and moisture protection. If the vinyl flooring product already has an attached underlayment, then there is no need for an additional one. However, if the product does not have an attached underlayment, then it is recommended to use one to maximize softness, warmth, moisture protection, and noise reduction. The type of underlayment to use depends on the subfloor and whether it is concrete, plywood, or an existing flooring material. Some popular options for underlayment include foam, felt, rubber, plywood, and OSB. The best underlayment to use for vinyl flooring depends on the specific situation and the desired benefits.
