How a laminate floor board is made
Laminate flooring is constructed of various
layers that are fused together. The surface is a plastic type of composition which is applied to the main core using heat
and pressure. The core is usually made of high density fiber or particle board, and the backing can be either a paper layer,
or another layer of laminate.
There are normally 4 layers in the make-up of laminate flooring and they can be assembled
in two different ways, which is either “direct pressure” or “high pressure”. Some manufactures also
add an “underpayment” which is attached to the underside of the laminate flooring. This is designed to
add sound insulation qualities
to the flooring and also helps cushion the floor. The material which is usually used is cork, felt, foam or other similar
material.
The direct pressure method
With the direct pressure method, all of the layers
are assembled at the same time and then heated and pressed together to form a bond. This is the most common type of laminate
flooring.
The High pressure method
This type of laminate flooring is
more often found in the expensive premium end of the laminate flooring market. It is a relatively new innovation which basically
treats the top and bottom layers of laminate flooring separately, and then fuses these onto the core layer under extremely
high pressure.
The 4 layers that makeup a typical type of laminate flooring are :
The wear layer
This is the surface that is walked on and is the
top-most layer. It’s typically made from cellulose paper that has been saturated with melamine plasic resins. This gives laminate flooring its excellent durability and scratch resistance.
The design layer
This is what gives the laminate flooring
its design, color and characteristics. It is the image that is seen through the wear layer and is usually
made from cellulose paper with a photograph or a pattered print copied onto it. As it is below the wear layer, and therefore
protected, it can not be marked, scuffed or fade.
The core layer
This is the main part of laminate
flooring and is usually made from a type of particle board. Various strengths
and thickness can be found, and a thicker core will be more stable. Some brands of laminate flooring have
the core layer treated with water repellant chemicals, and others have Paraffin wax impregnated joints to prevent water from
penetrating down into the core.
The stabilizing layer
This is the very bottom layer that is usually made
from cellulose paper that has been saturated with melamine plastic resins, just the same as the top layer. Its purpose is
to create equality on either side of the core layer so that one side isn't affected differently from the other, and thus have
unnecessary movement within the boards.
