Panel Products

Objectives• Identify the different types of panel products• Understand the composition of the various panel
products• Explain the advantages and disadvantages of
using panel products
Copyright © 2009 Delmar, Cengage Learning
Introduction• Panel products are important building materials
in today’s construction of cabinetry and furniture• Frequently used panel products are:
– Plywood, fiberboard, particleboard and melamine• These products have advantages such as:
– Being able to create large surfaces quickly– Being more stable than solid lumber because of not
having a continuous grain pattern

Plywood• Cabinet grade plywood may replace lumber in
cabinets or furniture– Provides the look of solid wood– Less time consuming to work and therefore less
expensive to use– Fabricated with fine veneer faces over a core

Plywood (continued)• Cores used to create cabinet grade plywood
– Lumber core– Veneer core– Medium-density fiberboard (MDF) core– Particleboard core
• Type of core used determines degree of stability and the ability to hold fasteners

Plywood (continued)• Veneer that is placed on the front and back of
the plywood is cut in one of three ways– Plain sliced– Quarter sliced– Rotary cut
• Possible to buy cabinet plywood that has already been finished

Fiberboard• Created by mixing wood fibers with resin and
bonding them together by radio-frequency adhesion or heat
• Has no grain at all, which makes it very stable• Comes in high, medium, and low densities

Fiberboard (continued)• High-density fiberboard (hardboard)
– Good choice for drawer bottoms and cabinet backs– Extremely rugged
• Medium-density fiberboard (MDF)– Provides a very smooth and stable surface– Excellent choice for jig material– Great base material for stained, printed, painted, or
laminated applications

Fiberboard (continued)• Medium-density fiberboard (MDF) (continued)
– Commonly used for furniture tops, drawer fronts, moldings, and shelving
– Can be shaped easily– Has some drawbacks:
• Hard on cutting edges of tools• Very heavy• Should not come into contact with water• Does not hold fasteners well

Fiberboard (continued)• Low-density fiberboard
– Not used by cabinetmakers– Primary use is in upholstery industry

Particleboard• Not as dense as either hardboard or MDF
– Is an adequate and less expensive alternative• Composed of small wood flakes, chips, and
shavings bonded together with adhesives• Often used as a substrate for laminates
– Frequently used for plastic laminate countertops

Particleboard (continued)• Hard on cutting edges of tools• Heavy• Does not hold fasteners well

Melamine• Thermally fused, resin-saturated paper finish
applied over a particleboard core• Highly stain and mar resistant• Comes in a wide variety of colors and wood
grain looks• Often the major component of inexpensive
furniture

Melamine (continued)• Requires no finishing; resin-saturated paper acts
as a finished surface• Since it has a particleboard core, its disadvan-
tages are same as those of particleboard

Advantages and Disadvantages of Panel Products
• Advantages– Stability– Reduced production time in building cabinets– Their use makes good ecological sense
Copyright © 2009 Delmar, Cengage Learning
Advantages and Disadvantages of Panel Products (continued)
• Disadvantages– Edges of the sheets must be covered– Poor fastener-holding ability; specialty fasteners have
to be used– Have only a thin veneer covering the core; deep
scratches will reveal the core and give away the fact that they are not solid lumber

Summary• Manufactured panel products are widely used in
the cabinet- and furniture-building industries• Panel products include cabinet grade plywood,
fiberboard, particleboard, and melamine• Panel products are far more stable than solid
wood• Primary drawback to panel products is that the
core is visible on the ends; edges must be covered
