Built from various wood layers with a hardwood surface, engineered floors are the modern alternative to solid wood. Built from various wood layers with a hardwood surface. Its layered development is more stable than solid wood and will not be as affected by humidity changes in the environment. This dimensional stability means there is less need to accommodate for seasonal movement when installing, a reduced acclimatization period and it allows engineered floors to be fitted above underfloor heating. This allows for a floating floor installation, some with a click system, making for a simple installation.
