What does engineered flooring mean?

In the past, solid wood flooring was the only option. In the late 90’s and early 00’s several manufacturers started to develop engineered boards. This meant that the basic core was made out of plywood or OSB. The top layer was made from solid wood. In this way they wanted to overcome the problem of stability with solid wood flooring. Later on, it also meant that these floors were very good for use over Unde Floor Heating. Also they perform much better under changing climate conditions. So if products are going overseas, or when you have a big difference between summer and winter, these floors are THE solution.
