Interior door: What's the difference between MDF, solid wood board and multilayer board?

Density board is actually a kind of high-density board, which is made of wood residue glue under strong pressure.

Solid wood board is a kind of wood board, also called fiberboard, which is made of complete wood (logs) by hot pressing, while multilayer board is just a combination form, which is made by soaking objects such as tree technology in water and then hot grinding.

Multi-layer board is composed of multi-layer boards, made of wood fibers or other plant fibers, and the solid board is not processed. Dense density board is an artificial board made of wood, paved and coated with urea-formaldehyde resin or other suitable adhesives.
