What does AC4 mean in laminate flooring?

Looking for a resistant, durable and economical flooring? AC4 laminate flooring offers excellent value for money with a matte or glossy wood finish.

AC4 laminate flooring is among the most flexible on the market, as it can be installed both in residential and commercial spaces with low to medium foot traffic. 

In this article, we will explain the main characteristics of AC4 laminate flooring.

What is AC4 laminate flooring?

As we have already explained in other articles of our blog, laminate floors are synthetic flooring formed by superimposed layers of different materials (usually plywood or fiberboard) that are arranged in a layered format.

This type of floor has 4 layers:

  • Protection layer or Overlay. This is the top layer, and its main function is to add strength and protection to the surface of the slat. 
  • Decorative layer. This is the layer where the design of the floor is printed and that will add a somewhat aesthetic finish (simulation of wood, simulation of natural stone or marble, creative designs, etc.). 
  • HDF core. Normally, the core of laminate flooring is a high-density wood board. This layer is the most important, as it determines its quality. 
  • Balancing layer. The balancing layer has two uses: on one hand, it serves as a barrier to stop the penetration of moisture from the subfloor; on the other hand, it helps to stabilize the floor.

From a functional point of view, laminate floors are classified from AC1 to AC6, although, commercially, it is common to find products from AC3 to AC6. 

The letters “AC” stand for Abrasion Class, and refers to the floor’s resistance to wear and abrasion, with AC3 floors being the least resistant and AC6 the most resistant.

Normally, the AC classification is accompanied by what is called the “ICE” Level, which refers to the floor’s ability to support impacts (i.e., objects falling on it).

Both parameters indicate the general resistance of the soil, being common to make this table of equivalences: 

  • ICE 31 /AC3 soils. Light resistance. They are recommended to be installed in residential areas.  
  • ICE 32 /AC4 floors. Moderate resistance. Recommended for houses and commercial spaces, but with low foot traffic. 
  • ICE 33/AC5 floors. Intense resistance. Recommended for both residential and commercial use.
  • ICE 42/AC6 floors. Maximum resistance to wear and impact. Recommended for commercial and industrial spaces.

In addition to the ICE and AC ratings, the quality of a laminate floor is also determined by

  • Its HDF.  Meaning, the density which the wood fibers which compose the laminated boards have been compacted. A higher density makes the floor harder and more resistant to humidity and temperature changes. 
  • The thickness of the core board. The thicker the laminate flooring core board, the better it will support twisting, cleaning products, footsteps, etc.
  • Whether surface treatment technologies have been applied.
  • The quality of the anchoring system between strips/boards.
