Plywood Laminated veneer lumber Particle board Medium density fiberboard High density fiberboard
Medium Density fiber board is 48 lb. board. High Density Fiberboard is 55 lb. board. Low Density Fiberboard is 38 lb. board. Ultra Light Fiberboard is 33 lb. board.
There are three kinds of fiberboard--low-density, medium-density and high-density. All three are made by mixing powdered wood fiber and adhesive, then pressing them in a hydraulic press. Low-density fiberboard is made by compressing a foot-thick pile of fiber to 1/2" thickness. Medium-density fiberboard compresses a foot of fiber to 1/4" thickness, and high-density fiberboard compresses a foot of fiber to 1/8" thickness. Low-density fiberboard is usually coated with asphalt on one side and used as cheap sheathing under siding on houses. Medium-density fiberboard is used for a multitude of purposes, and high-density fiberboard is used for laminate flooring.
You might choose a high-density fiberboard (HDF) or medium-density fiberboard (MDF) for a long shelf for heavy books. These boards are known for their stability and strength, making them suitable for supporting the weight of heavy items like books. Additionally, MDF and HDF are typically more affordable than solid wood options.
The differences between medium density and high density fiberboard (mdf and hdf) do vary slightly between manufactures. These are some general facts. MDF is a product of soft woods that are broken down by a defibrator, added to wax and resin, and formed from heat and pressure. The majority of the wood comes from saw dust. It is moderately resistant to termites and mold. It can be quite moisture sensitive. HDF is made in a similar process as MDF, but is much more dense and made from exploded wood fibers and quite a bit more pressure. HDF is highly resistant to mold and infestation and not nearly as sensitive to moisture as MDF.
One type of man-made wood is blockboard. It is made by glueing thin strips of wood from edge to edge, and then sandwiching them between veneers of wood which is then glued on under higher pressure. There is also another type called plywood.
