MODEL CSCLC 7: STRUCTURAL COMPOSITE LUMBER CORE

Interior

An all purpose door of seven ply construction. Three ply hardwood doorskins are permanently bonded to wood slab and frame. The core consists of Structural Composite Lumber that utilizes wood strands from a variety of tree species providing an alternative to dimension lumber.
The material is engineered for strength and stability. While not really “lumber” it is marketed as a lumber substitute, to be used primarily in place of stave lumber core materials. SCL is tested under a number of ASTM and other test criteria. The precision surface core provides a smooth stratum for the hardwood doorskins.
