Although many people assume that solid wood flooring is the best you can buy, that may or may not be true, depending on a number of factors.

First of all, let’s explain what engineered wood flooring is. It’s made by sandwiching together several layers, usually a veneer, a core, and a base. The veneer or top layer is the one you see and it can vary in thickness. Generally speaking, the thicker, the better.

One of the advantages of engineered wood flooring is that it’s easier to install than solid wood flooring. It can be glued down – which is essential if you have concrete sub floors – stapled, or floated. And it’s easier to saw and nail than many solid woods. If you want to install your floors yourself, they’re your best bet.

It can even be installed over tile or vinyl, as long as it’s clean and level. Check to make sure the moisture level is less than 4% first.

Because the grain of the core is perpendicular to the grain of the veneer, it’s actually more stable than solid hardwood. It warps less and is better suited to homes in high-humidity zones or for summer homes that are unheated in winter.

The best thing about solid wood is that if it gets worn, it can be sanded down and refinished. But people forget that even though the wood is ¾” thick, it can only be sanded down to the bottom of the tongue on the side of the plank. In most cases, that’s only about 5/16” thick.

An engineered wood floor with a veneer of 3/16” can usually be sanded three or four times. It should have a lifespan of 60 to 80 years.

Most engineered flooring comes pre-finished, which eliminates all the hassle of sanding and finishing your floors after they’re installed. With 3 -10 layers of urethane already applied, they’ll look good for years with proper care.

These days, you can find engineered wood flooring in virtually every wood, color, and finish. Even hand-scraped and distressed styles are available.

As a rule, engineered wood floors are less expensive than solid wood floors. But if you sell your home, prospective buyers will pay the same price. This is not true for laminate floors which don’t look like real wood.

Another benefit is that they’re environmentally responsible. The wood required to produce one square foot of solid wood flooring will yield approximately four times as much engineered product.

Read about other kinds of wood flooring.

Because wood flooring is easy to care for and doesn’t show dirt or stain like carpeting, it’s a good choice for families with children and pets.

When you first start shopping for wood flooring, you may be overwhelmed by the choices.  But there are basically just three types of wood floors.  The type that’s best for you will depend on a number of factors, including where the floor will be installed and how much traffic it will get.

Solid wood flooring.

As the name implies, solid wood flooring is made from pieces of wood that are between 1/4″ and 1″ thick.  As a rule, the tongue-and-groove boards fit together and are installed by nailing them to a sub floor of 3/4″ plywood.  For this reason, solid wood floors can’t usually be used over concrete slabs.

Building a sub floor to use over concrete essentially doubles the cost of using solid wood.  So if you have a concrete floor, you’re better off with an engineered wood floor.

Because solid wood expands and contracts with variations in moisture and temperature, it’s also unsuitable for areas where those conditions fluctuate dramatically.

You can choose from a wide assortment of solid woods, stains, and finishes.  Or you can buy your flooring unfinished and having it finished after it’s installed.  This is ideal if you’re trying to match a pre-existing floor.  But it’s a messy process and not everyone will be want to put up with the noise and dust.

Because there is usually 1/4″ or more of wood above the tongue and groove, solid wood floors can be sanded down and refinished.  If you have lots of traffic or large dogs, solid wood flooring are a great choice.

Engineered wood flooring.

This kind of flooring is made of several layers — or plys — that are laminated together.  Usually a base, a core, and a veneer.  The top layer or veneer varies in thickness.  But for the best wear, it should be at least 3/16th of an inch thick.

Veneers of 1/8″ or less are usually rotary peeled.  Thicker veneers are sawed and look more like solid wood.  Veneers of 5/16th can usually be sanded.

The grain on the plys in engineered wood run in different directions, which makes the flooring more stable.  Engineered wood flooring won’t warp, and because it can be glued, stapled or floated, it can be used almost anywhere.

Most engineered floors come prefinished with 3 – 10 layers of urethane.  But a huge selection of finishes is available.  If your sub floor is a concrete slab, engineered wood will cost you about half as much as solid wood.

Acrylic-impregnated wood flooring.

Better known by the brand name Pergo, acrylic-impregnated wood floors are extremely durable.  In fact, they’re 300% harder than natural wood.  Liquid acrylic, stain, and fire retardants are injected into the wood and then it’s cured.

Because impregnated wood is water resistant, it’s often used in kitchens and bathrooms.  And because the color goes all the way through, it’s ideal in commercial setting like restaurants, where there’s lots of traffic and wear.  In fact, scratches are barely detectable.

Many people don’t like the look of acrylic-impregnated wood floors, but they are the best choice if you want the appearance of wood but need a more durable floor.
