difference between pergo and engineered hardwood floor
This is quite a lot for hardwood flooring. Pergo is a floating type of floor, in that it is not attached to the subfloor, which may be concrete or even vinyl. The planks snap and lock into each other quite easily hence quick to install.
Engineered wood flooring is the type of floor that is most commonly confused with plastic laminate flooring. This is a wood floor which has a top wear layer, usually 1/8 thick on better products, and than has one or more layers or plies. The top layer is generally made out of oak, maple, cherry, etc.
