Hardwood | How It's Made
Knowing how hardwood floors are constructed can be very
advantageous. It enables you to understand the product’s
materials right from the beginning. Remember that these are
materials you will be living with, and on, should you choose to
have our hardwood flooring installed in your home.
Hardwood sizes, species and types
- solid wood floors means 3/4" thick plank that is 2 1/4"
wide
- classic strip wood floors mostly -random lengths from 12" –
84"
- most common species solid strip: red oak, white oak, maple,
cherry, white ash, hickory or pecan
- 3 common types of wood floors: Engineered, Solid, and
Longstrip Plank

Type 1: Engineered
- made with 2,3, or 5 thin sheets laminated to form 1 plank
- plies stacked in opposite directions- cross-ply
construction
- cross ply - dimensionally stable, less affected by moisture
than 3/4” solid
- with moisture, solid planks expand across width not down
length
- cross-ply advantage: plies counteract for plank growth,
shrinking with humidity changes
- versatile: installed over concrete slabs or other places
- installed by: nailed down, stapled down, glued down, or
floated
- over a wide variety of sub-floors, and some existing floors
- range: 1/4" to 9/16" thick
- width:2 1/4" to 7", mixed (3-5-7-inch planks installed side
by side)
- varying widths can change the appearance
- lengths random: 12" – 60" in length
- made of layers - top finish layer is different
species
- domestic or exotic species: Oak, Maple, Hickory or Cherry
Type 2: Solid
- one solid piece with tongue and groove sides
- unfinished and pre-finished 3/4” solid
- moisture factor: sensitive to moisture
- used in nail down installations
- not recommended for below ground level, or over a concrete
slab
- can be refinished, or recoated, several times
- natural product: expand and contract with season changes
(moisture)
- in winter heating months, moisture leaves the wood causing
contraction this creates gaps between planks
- in summer months, with high humidity, wood expands meaning gaps disappear
- too much moisture causes planks to cup, or buckle
- important to leave expansion around the perimeter
- important acclimate prior to installation
- Oak: used for solid unfinished floors - several qualities
to choose from
- clear-no visual blemishes or knots, expensive
- select and better- some small knots, little dark
graining
- #1 common, #2 common - more knots and dark graining
Type 3: Longstrip
- similar to engineered floors
- several wood plies glued together
- center core is softer, used to make the tongue and groove
with finish layer on top of the core
- top layer: any species made up of smaller individual pieces
laid in 3 rows
- 86" in length and 7 1/2" in width
- 17 and 35 pieces making up the top layer of each board
- each plank looks like a section already pre-assembled
- designed for the floating installation
- can be glued-down, or stapled down
- extremely versatile – can go over a variety of sub-floors
and grade level
- come in a wide variety of domestic and exotic species
- advantage: when damaged, they can be replaced easily
