The Vevor floor underlayment is designed to provide sound reduction, moisture protection, and added cushioning beneath laminate and wood flooring. Its recycled fiber construction with attached PE film helps reduce hollow floor noise while creating a waterproof vapor barrier. The large 200 sq. ft. roll is ideal for covering broad areas efficiently with less waste. This underlayment also helps smooth minor subfloor irregularities for a more stable finished floor. It is suitable for indoor spaces such as bedrooms, living rooms, studios, and bathrooms.
