Bottom Line (tldr;): - Both plywood and particle board are suitable for cabinet construction. If cost is no issue then go with a high quality plywood cabinet box. - A 45# particle board can outperform plywood when used properly - Beware of cheap plywoods - many imported cabinets are made from lower quality plywoods B
Kitchen cabinets are the cornerstone of your kitchen decor. Whether you go modern, traditional, or vintage, an important decision is what material will be used to make your cabinets from.
There are about 8 things to consider when looking at cabinets. Four of them have to do with the materials they are made from and the other two 2 have to do with how they are assembled, finished and packaged/shipped.
Cabinet Assembly and Handling
Today I want to talk about cabinet box construction and what to look for when you are shopping for cabinets at different price points. We'll tackle the other parts of the cabinet in later blog posts.
There are three kinds of materials for cabinet boxes: Solid Wood, Plywood and Particle Board.
Way back in the day solid wood was the only choice for cabinet box construction. It’s not used much today because it is expensive and solid wood tends to warp and twist easily, especially in humid environments. Its really just not a good choice for kitchen cabinet boxes.
Plywood is a composite material, similar to particle board, but made differently. Unlike particleboard (made of wood chips / wood pieces), plywood is made of thin sheets of wood glued together to make one sheet. One of the things that impacts the quality of a plywood is the number of layers it is made from.
Plywood is commonly made out of lighter wood, in many cases lighter than particle board which can make it easier to handle. Another factor in the quality of plywood is the type of wood used in each layer. Plywood is often more expensive than particle board so to cut costs some companies are using a thin outer layer of higher costs wood and using lower costs softwoods in the interior of the plywood.
You may automatically assume that your plywood would absorb less water than particle board but you would be wrong! Water can actually absorb faster into plywood than particleboard.
Plywood used to be a economical choice, however these days cabinet grade plywood is quite expensive and it looks like recent tariffs will only increase the cost.
Plywood comes in all kinds of varieties, some high quality, some low quality and everything in between
It can be very difficult to tell the difference between softwood and hardwood plywood. Price is usually the best indicator.
Particle board has been around since the mid 50’s. It was first made in a factory in Bremen, Germany during the second world war.
The first particle boards were expensive and not very durable. Today's particle boards are formed by using compression and temperature to make a much harder consistency.
Many manufacturers are moving to high quality particleboards in their cabinet construction because the material cuts and shapes more consistently, does not twist or warp like plywood and is a more uniform thickness than plywood.
Like plywood, particleboard comes in several varieties.
Check out the image below. On the left is a cabinet grade plywood. On the right is Industrial grade (45#) particle board. We place both samples in an inch of water with red food dye for 24 hours.
As you can see the plywood has delaminated and the water has wicked far up into the board. The industrial grade particle board has swelled slightly but shows much less damage.
Now, we don’t recommend you soak your cabinets in water for 24 hours. If however it does happen, modern particle boards hold up better than plywood.
Manufacturers know the general public has a bias towards plywood cabinets so they market their cabinets as “all wood”. But in order to cut costs low grade plywoods with softwood cores and very thin finish veneers.
Whether you cabinets are made from particleboard or plywood it’s important that the material is the highest quality.
It’s important to know that over the years particleboard earned itself a bad reputation because of how older cabinets were turning into mush with when they got wet from leaky plumbing.
Fortunately, particleboard has made quite the comeback since the 1960’s and 1970’s.There are now more high-end options that can serve to hold up many years and in some cases, particleboard can better support screws, due to its density. Also, high-end MFD can withstand situations that cause plywood to expand and contract.
You could also argue that particle board is the more sustainable option as it utilizes wood more efficiently in its manufacture.
Aside from the materials your cabinet box is made from you also want to consider how the box is put together.
Many lower end cabinets are simply stapled together with crown staples, which is a fairly flimsy way to construct a cabinet. Higher quality cabinets will use dowels or wood joinery techniques like dado channels to assemble the cabinet box.
You also want to pay attention to the shelf depth and adjustability. Some shelves are only ½ the depth of the cabinet, others are full depth.
Some cabinets are solid top, they have a solid ⅝ inch or ¾” solid top. Others are open on top. Solid top cabinets stay square better. Open top cabinets use corner braces or mid-rails to keep the cabinet square but often these come loose during shipping.
For the value it offers we think particle board is a great option and we specify it quite a bit. We also think its a more sustainable option and like the consistency of the material.
When we compare particle board cabinets to similarly priced plywood cabinets the plywood used is low quality and thinner than what we recommend for cabinet box construction.
High quality plywood cabinets cost roughly 20% more than cabinets made from high quality particle board.
There is a little bit of specialized knowledge needed when working with particle board cabinets but as long as you use the right fasteners and install methods they are a great option.
Our main cabinet lines, Bellmont and Dura Supreme both come with plywood and particle board options. Both companies use 45# industrial grade particleboard and have a limited lifetime warranty.
