Wood Composite Shutters are typically manufactured from MDF or Medium Density Fiberboard, which is then coated in a Polypropylene film to give the MDF an even more durable finish and a nice even finish that identically mimics the look of a painted wood shutter. MDF is a wood composite that is made from recycled wood fibers, wax, and resins; which are compressed together using extreme pressure and heat. MDF is an extremely popular material for Plantation Shutters due to both the straightness of the material, and the fact that it is an extremely dense material, giving it a hardness rating of approximately 1200 on the Janka Hardness Scale (For Comparison, softer wood like Basswood rate at about 410 and hardwoods like Red Oak rate at 1290). Because MDF is a Wood Product, it can be milled, shaped, and assembled using more traditional joinery. The MDF is Milled into the components of the shutters, cut to size for production, then laminated with a polypropylene film. After the components are laminated, they are joined together using wood adhesives and either bridle joints or mortise and tenon joints.
