3-in-1 Underlayments

Q: What does 3-in-1 mean for Underlayments?
A: Underlayments which are labeled as “3-in-1” are a combination underlayment which consist of a foam underlayment, vapor barrier and seam tape. This type of underlayment is great for an easy all-in-one underlayment to go over concrete. The difference between underlayments labeled as “2-in-1” versus the 3-in-1 underlayments is that the 2-in-1 underlayment will not come with seam tape. This tape is required in order to seal the overlapping areas of the vapor barrier when installing over concrete. 3-in-1 underlayments are a great choice if you are looking to save a few bucks, but they rarely suppress sound as effectively as underlayments like cork or Sound6. If you’re not worried about a laminate being a bit “clicky” or “hollow” sounding and you’re working over concrete, such as in a basement, this is a great choice to make your job easier.
