LAMINATE FLOORING CONSTRUCTION:
Laminate flooring is manufactured by using a tongue and groove glue or glueless method that creates a single unit that expands and contracts (invisible to the eye) with changes in humidity. As a result, it is resistant (but not foolproof) to normal household spills, tracked-in rain and/or snow.
The two types of laminate produced are high-pressure lamination and direct-pressure lamination:
HIGH-PRESSURE LAMINATION:
With this method the bottom and top layers are separately heated and consolidated into a laminate structure that is then permanently fused to the core. This produces laminate flooring that is more impact- and dent-resistant than the other method, direct-pressure lamination.
DIRECT-PRESSURE LAMINATION:
With this method layers are assembled all at once and permanently bonded to the core with hardening melamine resins. Because it is less impact- and dent-resistant, it is less expensive as well.
