Peaking Can Be Caused By Lack Of Space For Expansion

Laminate flooring is certainly no exception from one of the most basic laws of nature, that everything expands and contracts. This is why laminate floors that are installed correctly always have space between the edge and the molding. The planks have no choice but to push against each other if they don't have space to do anything else. They will then start to rise once enough pressure is there. Generally the effect is quite minor in the beginning, but you'll end up with a small mountain in your home if it's not taken care of.
