The AC rating on a laminate flooring is used to inform buyers of the
durability and performance of a laminate floor. There are five ratings:

AC1 - laminate flooring is designed for residential areas with light traffic.
Great for bedrooms.

AC2 - laminate flooring can withstand more traffic than AC1. Suitable for
living rooms and dining rooms.

AC3 - laminate flooring can withstand any type of heavy residential traffic
and may also be used in a professional setting with light traffic.

AC4 - laminate flooring is designed for commercial applications with
moderately intense traffic. Ideal for small shops and offices.

AC5 - laminate flooring is designed for high-traffic commercial areas like
department stores, shopping centers, and office buildings. It has a rough
finish that can withstand the most abuse.
