As a flooring expert with years of experience in the industry, I'm often asked about the role of underlayment in a flooring installation. Underlayment is a crucial component that serves multiple purposes, including providing a smooth surface, reducing noise, and managing moisture. When it comes to cork underlayment, it's important to understand its specific properties and how it functions as a moisture barrier, if at all.
Cork underlayment is a popular choice due to its natural, renewable, and environmentally friendly nature. It is made from the bark of the cork oak tree, which is harvested without harming the tree. Cork is known for its excellent insulation properties, as it provides both thermal and acoustic insulation. It also has a unique structure that allows it to be lightweight yet sturdy, offering a comfortable and warm surface underfoot.
However, when it comes to moisture protection, the role of cork underlayment is not as clear-cut. Unlike some other types of underlayment, such as QuietWalk recycled underlayment, which is specifically designed with a built-in vapor barrier, cork does not inherently possess moisture-resistant properties. The porous nature of cork allows it to absorb and release moisture, which can be beneficial in some applications, but it also means that it is not an effective barrier against moisture coming up from the subfloor.
Most flooring manufacturers require a vapor barrier to be installed beneath the flooring material to protect against this type of moisture. This is especially important in areas prone to high humidity or where there is a potential for water leakage, such as bathrooms or basements. Without a proper vapor barrier, the moisture can seep through the flooring and cause damage to the subfloor, the flooring material itself, and potentially lead to mold and mildew issues.
If you choose to use cork underlayment, it is essential to consider the environmental conditions of the space where it will be installed. In dry environments where moisture is not a significant concern, cork underlayment can be a suitable option. However, in areas where moisture is a potential issue, it is advisable to use an additional moisture barrier or opt for an underlayment that has a built-in vapor barrier.
In summary, while cork underlayment offers many benefits, it is not a moisture barrier in the traditional sense. It is crucial to assess the specific needs of your flooring project and choose the appropriate underlayment accordingly. Always consult with flooring professionals and follow the manufacturer's recommendations to ensure the longevity and integrity of your flooring installation.

There are many types of underlayment such as cork, rubber, and recycled. Some have vapor barriers built into them such as the QuietWalk recycled underlayment but cork and rubber do not. Almost every flooring manufacturer requires a vapor barrier to protect against moisture coming up from the subfloor.
