Product Overview

Let your floor breathe! This multifunctional underlayment from Kronoswiss provides heavy duty sound insulation underlayment. Optimized through extensive test series and laboratory tests to provide high-level, lasting impact sound insulation.

Kronoswiss ProVent not only effectivelly minimizes the noise level when walked on, but also the sound level transmitted through the floor into adjacent rooms. Rated STC67 IIC 71 provides great noise insullation; perfect choice especially in condos and other multi-floor constructions.

Unique Micropumping System supports air circulation. ProVent underlay is shaped to allow the formation of a system of air channels which ensures a constant exchange of air when walked on and also eliminates water vapor from the floor.


ProVent PE underlay comes with an integrated moisture barrier and overlap to provide vapor protection. CFC free can be disposed of in the household waste without problems, is recyclable, does not polute water and is toxically safe.

Area of use: Use it when installing any type of floating floorings. Not suitable for any type of flooring that needs to be fully glued to the subfloor .

    So Glad
    I searched high and low to find what I thought was the right underlayment. With so many products available on the market it makes it real hard to choose the one. I'm so glad I picked the Provent underlayment by KronoSwiss be the product went down easy and the floor feels great under foot. Thank you Best Laminate!

    very easy to install!
    This was our first time using an underlayment. Very easy to install and helped with echo that laminate floors can create. Plus best laminate processed order immediately and we received product fast. Would definitely recommend company and product:)

    great job of sound absorption
    I bought 11 rolls of padding from you for my new laminate flooring and I am very impressed. The padding went down well and does a great job of sound absorption. Would buy again!

    very pleased
    I purchased underlayment, no flooring, from BestLaminate and quite frankly, it is difficult to review this material for unless there is moisture from the basement, I really cannot determine if the product is working or not. The sound appears to be more muffled than what pre-existed, but I do not know if this is a result of the new flooring or the underlayment because the former is quite a bit thicker, 4-5mm, than what existed before the new installation.
    Placing the order was trouble free, the material arrived very quickly, and the contractor had no problem with installing the product, so in these respects I am very pleased with my order.
