MDF is an engineered lumber product made of sawdust bonded together with a urea-formaldehyde adhesive. Formaldehyde is suspected of being a carcinogen, and MDF has some of the highest concentration of urea-formaldehyde adhesives out of all the engineered wood products that use it.
What's the Best Material for Kitchen Cabinets?
- Solid wood. Wood is by far the most common material used for cabinets.
- Laminates. As solid wood is prone to damage and infestation, often laminates are preferred.
- Wood veneers. Veneers are slices or sheets of solid wood that are pasted over a composite substrate, just like laminates.
- PVC.
- Stainless steel or aluminium.
Although melamine may be strong enough to do your cabinets, plywood tends to be stronger. This in turn makes your cabinets withstand more.
Followings are the disadvantages of MDF:
- MDF is comparatively weaker than wood.
- MDF can crack or split under extreme stress.
- MDF absorbs water quicker than wood.
- MDF doesn't take nails and screws easily.
- MDF contains VOC, containing urea formaldehyde, that can cause irritation to lungs and eyes.
Not surprisingly, chipboard is a cheaper product than plywood largely because it's a wood product that can be made effectively from what is pretty much wood waste products. Plywood on the other hand is made from full sized sheets of very fine wood, making it a more expensive product to manufacture.
Unlike plywood and other fiber boards, hardboard is only sold in thin ? inch or ¼ inch thick sheets. Because it is so strong and durable, hardboard can often perform as well, if not better than, other fiber boards that are 3-6 times as thick.
Plywood is generally thought to be the better product when building cabinets. Plywood has superior construction longevity because it holds screws and other mechanical fasteners more efficiently. Many plywood manufacturers also make particle board from the leftovers. Because of this, particle board is less expensive.
Veneer core hardwood plywood is normally the lightest type of plywood you can buy. The core of this material is made from fir, which is a very light wood, and then a wood-grain veneer is placed on one side of the board.
Medium density fibreboard is stronger than chipboard because the board has a higher density. Medium density fibreboard also has a much smoother surface than particle board which allows for a better finish. Kitchen - MDF outperforms chipboard because it is water resistant.
Chipboard sheeting is usually pre-treated and is ok out in the weather for at least a few months. The sheeting will swell at the joins, this doesn't matter. It will dry out once the house is enclosed and then the joins are rough/level sanded prior to covering with carpet, vinyl, tiles or timber.
No such thing as waterproof chipboard. You may be thinking of moisture resistant. This is better than the standard stuff but still swells up if left wet for too long.
Medium density fiberboard is stronger than chipboard because the board has a higher density. The connection joints with Medium density fiberboard are more likely to hold then with chipboard. When it comes to the finish on both types of board, it is a good idea to use a wood sealant before painting.
Chipboard flooring has been specifically designed for use on floors. It's ideally suited for use as flooring in new builds, as a replacement board or for suspended floors over existing solid subfloors.
The chipboard flooring that we supply is strong versatile and offers high levels of stability. It's also treated with a water resistant resin that makes it suitable for use in humid and damp conditions like bathrooms and kitchens.
Although chipboard floor boards are available in 18mm and 22mm thicknesses you will almost certainly need 22mm thick for any normal modern flooring application. Boards are 600mm wide and 2400mm long, meaning they are fairly easy to manage plus quick and easy to lay.
Wood-plastic composite (WPC)
Like marine plywood, wood-plastic composite can be used in home spaces which are susceptible to heat and moisture, like the kitchen and bathroom. It can prove a useful material in making those kitchen shelves. The main benefit is that this material is highly resistant to rot and decay.Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming it into panels by applying high temperature and pressure. MDF is generally more dense than plywood.
Different varieties of plywood exist for different applications:
- Softwood plywood.
- Hardwood plywood.
- Tropical plywood.
- Aircraft plywood.
- Decorative plywood (overlaid plywood)
- Flexible plywood.
- Marine plywood.
- Other plywoods.
If you ever wondered “what is the strongest plywood?” The answer is Marine plywood. It is the strongest and toughest of all plywood on the market. It is bonded with high-quality glues to make the plies structurally solid and resistant to moisture.
Why MDF is safe to use. Formaldehyde is an integral part of the adhesive used to bond together the wood fibres which form MDF panels. At extreme concentrations, formaldehyde is known to cause some serious health problems but there is no health risk from the amount of formaldehyde gas given off by MDF.
Plywood Thickness
Make cabinet sides of 3/4, 5/8 or 1/2-inch plywood. Choose 3/4-inch or 5/8-inch to use European style hinges. Selecting 1/2-inch plywood for cabinets with face frames will save money and weight.EGGER Thin MDF board is an extra thin, medium density fibreboard. Due to its standardised structure it is very good for profiling and easier and cleaner to process. Its surface is regular and fine-fibred. It can be coated with laminate, paint, finish foil and veneer.
MDF offers a smoother surface than plywood, making it the optimal choice for painted cabinets, according to the National Kitchen and Bath Association. Plywood generally won't look as smooth or polished when painted, and is best used with a veneer finish rather than paint or stains.
Soft woods such as pine and birch are relatively inexpensive but are less durable than hard woods and, no matter how many coats of paint or varnish you apply, they can be quite easily dented and scored by your tools and materials.

| Particle Board Core Melamine and Domestic Hardwood Panels | 3.50 |
MDF is commonly used for shelving in closets and cabinets because it's inexpensive and smooth. But MDF isn't as stiff as plywood and will sag over time. The MDF edge will absorb a lot of glue, so spread on a light coat, give it a minute to soak in, and apply another bead before you add the wood nosing.
Plywood Holds the Moisture Advantage Over OSB
When plywood gets wet, it tends to swell. OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists. However, nail-holding ability controls performance in shear wall applications.
Plywood. While OSB (Oriented Strand Board) is generally cheaper than plywood, it is heavier and not as stiff as plywood and can result in soft squeaky floors under weight. The biggest complaint against OSB is that it doesn't handle moisture very well so it is more suited for indoor use.
Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists. However, nail-holding ability controls performance in shear wall applications.
OSB is cheaper than plywood by about $3 to $5 per panel. For a typical 2,400 sq. ft. home, OSB is about $700 less expensive compared with plywood if used as the subfloor, sheathing, and roof decking.
STABILITY: Plywood is engineered (because of the perpendicularly layered grain) to be more stable than solid wood. So, in the end (at least for construction grade projects), the creation of plywood's larger more stable surface is a reasonable argument for it's extra cost.
Polyethylene is a Class I vapor retarder. A kraft faced fiberglass batt is a Class II vapor retarder. Latex painted gypsum board (one coat of latex paint) is a Class III vapor retarder. Plywood sheathing and oriented strand board (OSB) have perm values of greater than 1 perm when using the wet cup test.
Plywood is a viable alternative to drywall for walls and ceilings. If you are planning on redoing your walls or ceilings, the typical materials you'll use include Sheetrock or finished plywood. Each has its benefits as a building material and in some cases, finished plywood is the better alternative.
