Abrasion class (ac) ratings are an industry-wide system of classifying laminate flooring by its durability. AC ratings are broken out into five different levels.
Laminate flooring is available in various styles, patterns, textures and colors, regardless of its AC rating. AC ratings are not meant to distinguish poor-quality flooring from high-quality flooring. Instead, they are an easy way to classify laminate flooring into different categories so you can make a sound investment for your space.
