You did a good job explaining it.Ok the difference between hardwood and engineered floor is hardwood is the species of wood all the way thru the plank, engineered is basically plywood (no movement- expansion or contraction) with whatever species of wood you want on top so you could match. Hardwood can be refinished quite a few times, engineered can only be refinished about 3 times, if this is important to you. The decision is yours I'm just trying to give you another option. There are some flooring guys on here that may do better at explaining this than I did, they should be along to help.
Many engineered floors can have as thick of a top layer as real solid hardwood. So it can be refinished just as many times. A couple good brands to check out are real hardwood floors and shamrock. You can find both online. Hope this helps.ok- i feel better to investigate and explore engineered with that explanation- i lumped all flooring into 2 catagories real wood floor and fake floating floors- i do not like the laminate (wood)flooring and have installed a couple for others. this sounds like wood onj wood wich wouldnt have the dreaded click sound when walking on
