Thicker laminates will last longer?
No There is a misconception that thicker laminates perform better. There are some laminates on the market, that are 12mm thick. Some of these laminates have poor joint mechanisms. (B&Q’s AquaLOC+ has a particularly flimsy joint mechanism). Its the thickness of the wear layer that’s important, not the thickness of the board itself. Of coarse thicker boards sometimes have bigger joint mechanisms, and can hold together better. Thicker boards are also stiffer, but since laminates must be fitted on a perfectly even surface, this is irrelevant.
