The top transparent wear layers have different wear-resistance and thickness, i.e. AC3, AC4 and AC5. AC3 being Residential, AC4 being Medium Commercial and AC5 being Commercial. The wear layer can also feature texture to resemble and feel the genuine wood grain. The wear layer can also be impregnated with a metal compound known as aluminium oxide, which serves as the armour against scratches, impact and UV rays, ensuring a strong, unfading laminate floor. These will all impact on the price point.
