I am thinking about putting down about 500 sq ft of Engineered Wood Flooring instead of Laminate. To keep it quiet for the neighbors below, I am thinking about using a cork underlayment. Since this install will be on the 2nd floor, do I still need to use a moisture barrier under the cork? Also, do I have to glue the cork down? I would rather not- the floor might be gypcrete which might not like glue. I am planning to float the floor using a click lock system. This is my first time so any other suggestions would be appreciated e.g., type of species to use, tips, etc.
You will not need to add a moisture barrier. You do not need to glue down the underlayment or flooring on a floating floor. You will need to tape down the underlayment. Buying good underlayment will make the floor quieter for the people on the first floor and make the feel of the floor softer for you. Good luck putting in the floor. I have installed several. Make sure you buy the install tools. They are cheap and will make the installation smoother.
