At Clarion Boards, we produce high quality fiberboard used in the manufacture of products such as laminate flooring, furniture, fixtures, cabinetry and moldings.

Fiberboard is a panel made out of wood fibers and glue (resin). Clarion Boards makes two distinct types of fiberboard: MDF (Medium Density Fiberboard) and HDF (High Density Fiberboard).

MDF (Medium Density Fiberboard)

MDF is a composite panel product consisting of cellulose fibers and a synthetic resin or other suitable glue, which bond together under heat and pressure. The resulting density of the product falls between 38 lbs/cubic foot and 48 lbs/cubic foot.

The surface of MDF is flat, smooth, uniform and free of knots and grain patterns, which make finishing operations easier and consistent, as required by demanding uses such as direct printing and the overlay of thin films. The homogeneous density profile of MDF allows for intricate, precise machining and sophisticated finishing techniques. MDF is the material of choice for end uses where Particleboard is not technically an option.

MDF is widely used in the manufacture of furniture, cabinets, door parts, moldings and millwork.

HDF (High Density Fiberboard)

High Density Fiberboard (HDF) is produced in the same way as MDF, but applying higher pressures, which results in a product with a density between 49 lbs/cubic foot and 60 lbs/cubic foot.

HDF is primarily used as a substrate for flooring products, such as laminate flooring and engineered wood flooring. The moisture resistance of HDF is achieved by the addition, during the manufacturing process, of wax or other water repellent materials.
