I bought nearly 2000sf of floating click-n-lock floor. It came in 3 sizes, 4ft, ~3ft, 18" and 1ft lengths. We purchased very good underlayment at $38 per 100 sf. After the first 1000sf I stopped installing and called the manufacturer. Every step squeaked. I could even hear my 15lb shiz-tzu squeak the floor. Previously I had Kahrs floating floor and it did not squeak; but it was installed in 2001 with 8" wide 8 foot length pieces that were glued together(not to the concrete slab). I liked it but a broken fridge line ruined it so we had to replace the floor. Since it didn't squeak I didn't expect this new floor to. The manufacturer said it was defective wood, refunded me all the money for the wood, took back the unopened boxes and told me to throw out the 1000ft I had laid. I don't believe it is defective. I think this is what you get with this stuff. So after consultation, we decided to glue our floor down. We pulled up the floated floor, bought some more wood and had a professional re-install(with very good adhesive/glue). It doesn't squeak but we don't have that soft feel of floating floor that I liked. Also, I believe they used a urethane adhesive and it did not smell at all. Absolutely no glue smell. If you don't like the creaking, be careful with floating floor.

We have a cold crawl space under our flooring. Put engineered wood (hickory with no edge bevels) over a 1/4 inch cork underlay. Never noticeably cold and easy on the feet. My wife loves the floor. Warning: dropping knives or cast iron pans will damage engineered wood. We've done it! Also my wife knocked over a whole bottle of super glue on it and didn't wipe it up (she didn't notice it). That was/is a mess. Much scraping and still there are scars. I will have to sand and refinish the spots at least to make it look decent.

Laurie, what flooring did you choose? I am also interested in more information on the underlayment for an engineered wood floor. I am still deciding but must wait to do my wood floor now after my tax season since I am now so behind from finally just about finishing the tile job. My job entails moving a lot of heavy office furniture with files in the cabinets so it unfortunately looks like the job may have to wait and I will have to keep steam cleaning the very light beige carpet every 3 weeks.

Hi Wendy, "Yes" to answer your question. Just make sure that you have left the proper space around the room for expansion. Most engineered floors require 1/8" to 1/4" gap or space. This can be covered with your base or shoe molding. Hope this answers your question. Chris @ Nicefloors.com
