Laminate is a great way to transform your floor with an expensive looking imitation wood floor
What you essentially have is highly compacted melamine resin and fiber board then a high-resolution image of the pattern under a protective layer. It’s not often suitable for places with moisture/water due to swelling, you can now have water resistant laminates, but these carry a higher price.
Engineered and Real wood. Engineered wood usually has between 3-6mm of the actual type of specified wood, this would be able to be sanded back and treated several times before getting to the engineered part of the click system. Extremely durable and can cost more than ‘real’ wood.
