Engineered hardwood is different from solid hardwood in many respects, including
materials, structural composition and resistance. Below is a detailed analysis
of some selected differences.
SOLID WOOD
ENGINEERED HARDWOOD
Composition
Solid wood is milled from a real hardwood species, making it the
sole material used in the making of the flooring.
Engineered hardwood is actually produced with three or more
layers of HDF, MDF, with a real hardwood vaneer bonded together under heat and
pressure.
Strength
Noted for adding overall structural strength to the building in
which it is installed. The degree to which this is true depends upon the
species.
More suitable in high-moisture areas or in areas of frequent
temperature changes than solid hardwood due to its "multiple-ply plank"
manufacturing.
Uniformity
Uniformity varies depending on grade. Some grades allow for
multiple knots, for example.
Engineered hardwood is designed for optimal uniformity.
Dimensional stability
Prone to expansion, warping, cupping, to a significant degree when
exposed to temperature changes.
Constructed to be more dimensionally stable through multi-ply
design. This allows greater resistance to temperature changes.
Resistance to moisture and heat
Solid wood is unsuitable for applications at any location with
increased moisture or high temperatures. These could be areas which are not
environmentally controlled, damp areas such as below-grade installations and
over radiant heat.
Engineered hardwood is surely a suitable choice when solid wood
is not applicable due to increased moisture or heat. It is more resistant to
both if compared to solid wood.
Resistance to climatic changes
Solid wood generally expands and contracts a lot more than
engineered wood during climatic changes, especially extremes in heat and cold
and rainy season.
Engineered hardwood does not warp or cup during climatic
changes. It is more resistant to higher moisture levels than solid flooring. It
is a better choice for installation over radiant heat sources, damp basements,
and at locations in rainy climates.
