AC4 laminate flooring refers to a specific type of laminate flooring that has been rated for abrasion resistance. AC4 is the second highest rating on the Abrasion Class (AC) scale, which ranges from AC1 to AC5. AC4 laminate flooring is designed to withstand heavy residential use and moderate commercial use, making it a durable and long-lasting flooring option.

The 12mm thickness refers to the overall thickness of the laminate flooring. A 12mm thickness is considered thicker than average and provides added stability and durability. The thicker the laminate, the more resistant it is to impacts, moisture, and wear.

When choosing 12mm AC4 laminate flooring, you can expect a high-quality product that can handle everyday wear and tear, making it suitable for high-traffic areas. It provides a stable and comfortable walking surface and can resist scratches, fading, and stains.

It's important to note that while the thickness and AC rating are essential factors to consider when selecting laminate flooring, other factors such as the quality of the laminate, installation method, and proper maintenance will also play a role in the overall durability and longevity of the flooring.

Laminate flooring typically consists of four layers:

1. Wear Layer: The top layer of laminate flooring is the wear layer, which is a clear, protective coating made of aluminum oxide or melamine resin. This layer helps to protect the floor from scratches, stains, and fading.

2. Decorative Layer: The decorative layer is a high-resolution photographic image that is printed onto a thin sheet of paper or film. It is designed to mimic the appearance of various materials, such as hardwood, stone, or tile. This layer gives the laminate its desired visual effect and can vary in design and style.

3. Core Layer: The core layer is the main body of the laminate flooring and provides its structural stability. It is typically made of high-density fiberboard (HDF) or medium-density fiberboard (MDF) that is treated with resin for added moisture resistance.

4. Backing Layer: The backing layer is located underneath the core layer and provides further support and stability. It is usually made of melamine resin or plastic to add moisture resistance and protect against warping.

These layers are bonded together using a lamination process, which involves heat and pressure, creating a solid, durable laminate flooring product. The specific composition and quality of each layer can vary depending on the brand and quality of the laminate flooring.
