Yes. The door is built with no hollow cavities. The advantage with our doors is the engineered frame built with thick veneers over a stave core. The cores are built with the same material as the faces. In simple terms it is a bunch of laminations that you cannot see from the face of the door. The more laminations one has the stronger and more stable it becomes. See our glossary page for a better understanding of this when you look at the cross sections.
