Overlay: Top layer protects laminate flooring from scratches.
Decor Paper: Decorative layer, which gives different alternative colours and designs to laminate flooring.
HDF: High density fiberboard.
Balance Paper: Bottom layer, which protects from humidity and distortion, provides stabilization.
The essential difference between the two grades(AC4 and AC3) is the density of the High-density Fibreboard (HDF) used and the number of abrasion cycles it can withstand. They have the same thickness of the Décor pittsburgh steelers Paper being 0.10mm; aluminium oxide coating bearing 90-100 microns supported by balancing paper at the bottom of thickness 0.10mm precisely.
|Average abrasion value||> 900||> 1800||> 2500||> 4000||> 6500|
