Moisture Protection for Hardwood Floors

Consider Vapor Retarder for Hardwood Floors

Hardwood isn’t cheap and spending a couple cents more can help support the structure of the floor. No matter what application you use hardwood wood for, wood absorbs moisture from air. Too much moisture and the wood will start to bow and not enough moisture, cracks and separates. Keeping the correct moisture level for your floor helps strength and durability. Using a vapor retarder below your hardwood floor slows down the passage of moisture from reaching.

According to NWFA – a vapor retarder is to be used under hardwood flooring. If you have a NWFA installer installing your floor, they will follow their association installation guidelines. No underlayment is stated in their installation guidelines and any underlayment will get rejected of installation.

Moisture/Vapor Barrier for Hardwood Floors

A vapor barrier or moisture barrier is another term that often gets misused with vapor retarder and is completely different. Vapor barrier actually blocks all moisture from transferring. Built-in vapor barrier allows no moisture to get to your hardwood flooring. This can be good and bad in certain situations. Each situation can be different, so please give us a call at (888) 379-9695 and we can help steer you in the right direction.

Clean Indoor Air Quality
