What Are Engineered
Floors?
For lack of a better way
of describing engineered hardwood floors, they
are constructed similar to that of
basic plywood with the top surface being the
actual hardwood. Products come in two to ten ply
construction depending on the manufacturer. On
the right is a general overview of three strip
engineered hardwood, common with original
floating floors.
But They
All Look The Same!
Engineered
hardwoods have been given a bad rap over the
years because they all looked basically similar.
Earlier versions had one boring looking
appearance because all were rotary peeled.
Rotary peeled hardwoods offer a plywood
surface appearance. Some like it, others
don't.
Several high
quality manufacturers have been offering solid
sawn engineered hardwoods. Solid sawn exhibits
the appearance of traditional 3/4" solid
hardwoods many of us are accustomed to.
My Builder
Says It's Junk!
Ask any craftsman,
builder, or installer from the old school what
they think about engineered flooring and the
answers will likely be the same. Sure, there are
many low priced engineered floors out there sold
in places like Carpet One, Lowe's, and smaller
retail stores. They have their place and people
buy the stuff in droves.
Times Have Changed
With Quality
Times have
changed with engineered flooring.
Many manufacturers have increased the surface
(also known as veneer or wear layer) layer that
will result in some engineered floors lasting
just as long as more traditional solid 3/4 inch
flooring. One of the most important factors
contributing to the longevity of any hardwood
floor is the amount of refinish able material.
Solid 3/4"
hardwoods have approximately 1/4 of an inch
above the tongue and groove construction. Once
it
is sanded to that level, nails or staples begin
to appear and should be replaced. The better and
thicker engineered hardwoods have 1/8 to 3/16"
of an inch above the tongue and
groove. Illustration right.
More Stable Than
Traditional Hardwood
Engineered floors are the
ideal solution for hardwood flooring on
concrete, and there are other benefits. Most
recognized is the dimensional stability of the
way they are constructed. Each ply layer is
pressure glued and set in the opposite
direction. For those that are concerned with
high humidity, engineered hardwoods expand and
contract little if any, opposed to solid
hardwoods.
How Are They Installed?
Most engineered hardwoods
are installed by the glue down or floating floor
method. It's important to note; not all
engineered products have the same type of
installation specifications. In other words,
some may be floating, glue direct, or staple
only only. Manufacturers specify installation
applications for a reason, and we suggest
following them.
The Length Factor..Long
or Short?
Unfortunately many who
purchase engineered hardwoods don't know what
they're getting until the floor is being
installed. The majority of prefinished
engineered hardwoods have limits on lengths at
42 to 48 inches, opposed to most solid hardwoods
at 72 to 84 inches.
Longer lengths are
preferred as they offer a more appealing look on
completion.
Engineered Thickness
Choosing which thickness
of engineered flooring is often a confusing one
for consumers. Overall thickness of
engineered
floors will vary from 1/4" to 9/16" depending on
what brand or manufacturer. The most common
thickness seems to be 3/8" or 1/2" Which one to
choose? As we've already mentioned the wear
layer should be given priority in some
situations. Other factors that can come into
play would include adjoining types of floor
covering. Ceramic tile usually finishes at 3/8"
in vertical height after thin set is applied
under the tiles. For engineered hardwoods over
1/2" in thickness prefinished
moldings/thresholds can create problems in this
scenario.
How Many Plies?
In general the more ply
layers in construction the more stable the
product will be. However, this should not be a
determining factor in your selection unless
you're using the product over radiant in floor
heat. You'll find ply layers vary from two to
ten with manufacturers across the board. We find
the actual wear layer thickness should be given
priority if you plan on living in the home for
an extended period of time. On the other hand,
if you don't plan to live in the residence for
more than five or ten years others can be chosen
at lower costs. |
