Laminate flooring comes in either planks or square
tiles. They are designed to replicate real flooring materials - such as wood, stone or ceramic tiles. These floors
are actually several different layers of various materials that are pressed
together to form each plank. A printed film gives the floor the look of a
real wood or tile and is protected by a tough, durable wearlayer that goes on top of the print layer. The resins used in the wearlayer are said to be almost as hard as diamonds and
provides unsurpassed wear and stain resistance.
The inner core is generally made from high-density
fiberboard and also forms the tongues and grooves for locking planks
together. The core is also the base that all the upper layers and the backing
material are fused too. Some manufacturers treat the inner core with melamine
resins or water-resistant sealers to help protect the inner core from
moisture.
The laminated planks are usually fused together in either
a one or two step process. In the two-step process several layers are first
glued together and then these layers are combined with the remaining
materials and than glued and fused into a plank. This method is called High Pressure Laminate (HPL). The
other method is where all materials are fused together in one step and this
is called Direct Pressure Laminate (DPL).
The planks have tongue and grooved edges on all 4 sides
to secure the planks together. Today, most laminate floors use some
sort of glueless locking system, often referred to
as "clic" floors. Glueless laminate floors can go almost anywhere in the
home and are ideal for do-it-yourself projects.
The two main glueless locking
systems either involve a tongue and groove that is reinforced from underneath
by an aluminum, mechanical locking system or a tongue and groove locking
system built right into the middle core that allows the planks
to snap or clic together.
Some other laminate floors have a
tongue that was pre-glued at the factory with a specially
formulated, water-resistant glue. Once the tongue is moistened
with a wet sponge it activates the glue and locks the planks
together. Laminate floors are also offered that require specially formulated
glue to be applied to the tongue and groove at the time of the installation
to secure the planks to one another.
For more realism several laminate manufacturers are now
offering a micro-beveled edging on certain styles. Others have added
texturing to their surface layer to give their floors more realism and
enhance the overall appearance of the laminate planks.

- Backing - is usually a
melamine plastic layer used to give additional structural stability and
added moisture protection to the planks.
- Core - generally made
from high-density fiber board (HDF), particle board, or plastic, the
core adds impact resistance, and forms the tongue and groove locking
system. Melamine plastic resins are also impregnated in the core by some
of the manufacturers to improve the moisture resistance of the core.
- Melamine - is a
plastic-type resin used throughout the construction process to add
durability, and stability to the laminated planks.
- Print Film - which is also
called the decorative layer gives the floor the appearance of a real
hardwood or tile. Some manufacturers, have been
able to replicate the old wood floors found only in some old historical
buildings.
- Wearlayer - is a tough clear
melamine layer with aluminum oxide particles. Using heat and pressure
the wearlayer becomes an incredibly hard and
durable finish. The resin-filled wearlayer is
so dense it becomes extremely difficult to stain, scratch, or burn.
- Underlayment - is a clear thin
plastic sheet that is installed over the substrate before the laminate
floor is floated. The plastic sheet helps the laminate floor to float
freely above the substrate.
