Engineered wood versus solid hardwood

Questions regarding the proper wood flooring to choose? Engineered or solid? The easiest answer is to ask the question, are you on a main level of the house and if so is is it concrete. If it is concrete the recommendation would be an engineered product.

 There are several types to choose from such as a glued together tongue and groove, a click together "floating floor" system or a glue down method. In my opinion, the glue down method is the most stable of the three.

 Engineered wood in it self is a more stable wood product because of the layers of wood glued together,one on top of each other, with the grain going in a different direction each layer. What this does is reduces the amount of expansion and contration. A solid product will absorve moisture in humid climates and expand. While in a dry climate shrink, thus having both climates,your wood will exppand in the summmer and shrink in the winter. Engineered will not go thru this change.
A solid hardwood product is not recommended "below grade". Which means under the main level of your house. I will get more detailed pictures in a few hours.
