The thickness of a laminate plank, typically ranging from 7mm to 12mm, contributes to the overall stability and sound-dampening qualities of the flooring system. Thicker planks often feature more robust locking mechanisms, which can reduce the 'hollow' sound associated with thinner floors. While thicker boards are denser, the acoustic performance is significantly enhanced by installing a high-quality sound-reducing underlayment. Underlayments are specifically engineered to minimize impact noise and walking sounds, making them a more critical factor for sound control than plank thickness alone.
