Moisture is a silent enemy that can wreak havoc on your flooring, leading to warping, buckling, mold growth, and even structural damage. Whether you're installing new floors or replacing old ones, understanding the different types of moisture barriers and their applications is crucial for safeguarding your investment and ensuring the longevity of your floors.
Why moisture barriers are important
Moisture can seep into your subfloor from various sources, including the ground below, humidity in the air, or spills and leaks. Even minor amounts of moisture can cause significant problems over time, especially with moisture-sensitive flooring materials like hardwood, luxury vinyl, or laminate.
Moisture barriers act as a protective shield, preventing moisture from reaching the subfloor and damaging your floors. Learn more about the importance of moisture barriers in our blog: Moisture Barriers: Do I Need One?
Types of moisture barriers
Polyethylene sheeting:
This is the most common and affordable type of moisture barrier. It comes in various thicknesses, typically 6 mil or 10 mil. Polyethylene sheeting is laid directly on the subfloor before installing the flooring. It's effective in preventing moisture vapor transmission and is suitable for most flooring installations.
Vapor retarders:
These are similar to polyethylene sheeting but are designed to slow down the rate of moisture vapor transmission rather than completely blocking it. Vapor retarders are often used in conjunction with other moisture barriers to provide an extra layer of protection.
Liquid moisture barriers:
These are applied directly to the subfloor as a liquid coating. They dry to form a waterproof membrane that prevents moisture from entering the subfloor. Liquid moisture barriers are easy to apply and can be used on various subfloor materials.
Two-in-one underlayment with moisture barrier:
This type of underlayment combines a moisture barrier with a cushioning layer. It simplifies the installation process and provides both moisture protection and sound reduction.
Cork underlayment:
Cork is a natural material with moisture-resistant properties. It can be used as an underlayment to provide additional moisture protection while also offering thermal insulation and sound absorption.
Choosing the right moisture barrier type for your luxury vinyl installation
The type of moisture barrier you choose will depend on several factors, including:
The type of flooring:
Different flooring materials have varying moisture sensitivities. Consult the manufacturer's recommendations for the appropriate moisture barrier for your chosen flooring.
The subfloor material:
The moisture barrier should be compatible with your subfloor material. Concrete subfloors may require different barriers than wood subfloors.
The climate:
In humid climates, you may need a more robust moisture barrier to protect against excessive moisture vapor.
