underlayment

Underlayment is a supportive layer installed beneath the finished flooring, such as hardwood, laminate, or tile. Its primary functions are to provide a smooth, even surface, enhance the flooring’s durability, and improve insulation and soundproofing. It also helps absorb minor subfloor imperfections and reduces noise transfer between floors. Different types of underlayment are used depending on the flooring material and specific needs, such as moisture barriers or thermal insulation. Proper underlayment ensures the longevity, comfort, and appearance of the finished floor, making it an essential step in many flooring installations.
