Here's a quick summary of what laminate flooring is and the pro's and con's of using it.
Laminate flooring has a particle board core and is filled with melamine resins to make it scratch and scuff proof
Laminate flooring is known as a 'floating' floor as it's not attached to the sub-floor with nails or glue. This allows the floor to contract and expand as designed, without affecting any other structures.
Sheets of flooring are snapped together or glued to ensure no cracks or gaps.
A good laminate floorer will arrange to leave the laminate flooring in the room it will be installed in, for at least 2-3 days before the installation actually happens. This ensures that the flooring acclimatises to the moisture/humidity levels in the room and expands before the installation is done.
Laminate flooring is sensitive to moisture and it's not a good idea to install it in bathrooms or laundries, and you should wipe up any spills immediately.
Pros and cons of laminate flooring
Pro: Laminate is easy to clean and is thinner than hardwood floors so can often be laid over existing floors
Pro: You can hammer it and no marks - durable and can withstand lots of traffic
Pro: Quick to install - have it done in a matter of hours
Con: Sensitive to liquids, especially around the edges - the wood will swell
