In general, 12mm laminate flooring is considered better than 8mm laminate flooring in Australia because it tends to be more durable and long-lasting.
The thickness of the laminate flooring is an important factor to consider when choosing a product. Thicker laminate flooring tends to be more stable and resistant to warping or bending over time. It can also provide better sound insulation and a more solid feel underfoot.
Additionally, thicker laminate flooring often has a more realistic look and feel, with deeper embossing and texture that mimics the look of real hardwood flooring.
That being said, the choice between 8mm and 12mm laminate flooring will depend on individual preferences and budget constraints. 8mm laminate flooring can still be a good option for some applications, especially in areas with less foot traffic or where cost is a primary concern. However, for high-traffic areas or for those who want the most durable and realistic flooring option, 12mm laminate flooring is generally the better choice.
