Laminate flooring is made of various layers that are fused together. The layers in most laminate flooring include:
Wear Layer - This is the top
layer, the one you walk on. It's usually made from cellulose paper
that's been saturated with melamine plastic resins that make laminate
flooring so incredibly scratch-resistant.
Design Layer - This is the
image you see, typically a photograph or patterned print that has been
copied onto cellulose paper. Because it is below the upper melamine
layer, it can't be marked, scuffed or even fade.
Core Layer - This is the
backbone of all laminate flooring. The core layer is usually some form
of processed particle board and comes in different strengths and
thicknesses.
Stabilizing Layer - This is the
bottom layer that holds everything in place. It's usually made from
resin-saturated paper, just like the top layer.
In addition, some brands of laminate flooring have an
underlayment attached to the bottom. The underlayment is designed to
absorb sound and cushion the floor. It is usually made of cork, felt,
foam or some similar material.
Laminate Flooring is put together in two different ways.
Direct-pressure laminate flooring is the most common variety. All the layers are assembled at once, then heated and pressed to form a bond.
High-pressure laminate flooring
is a more recent innovation and is often found in more expensive
premium brands. Both the top and bottom layers of high-pressure
laminate flooring are treated separately, then fused to core layer
under extreme pressure.
