Laminate flooring has a layered construction:
A) Wear layer: This easy-to-clean surface contains aluminum oxide which protects the floor from stains, fading and wear.
Look for an abrasion classification (A/C) rating of at least 3 for adequate residential use protection.
B) Image design layer: A photographic image of wood, stone, or virtually anything you can imagine.
C) Inner core layer: The core provides the floor's structural strength and stability. It is made from high-density fiberboard (HDF). The core is often impregnated with a plastic resin called melamine to increase the floor's strength, stability and resistance to moisture. Products that have high levels of melamine do not require acclimation before installation.
D) Backing layer: Found beneath the inner core, the backing is made with resin saturated paper. It creates a moisture barrier that protects the floor from warping.
All laminate floor layers are fused together using one of two processes. DPL, or direct pressure laminate, is the most common construction for residential use. HPL, or high-pressure laminate, is an extra-hard construction. The difference between the two relates to cost, performance and design realism. DPL is less expensive, has the same gouge resistance as HPL when objects are dropped at or below counter height, and is easier to emboss for more realistic texture. HPL is more expensive and less likely to gouge if items are dropped from above counter-top height, but is harder to emboss, so it doesn't look as realistic. |
