Hey There: Vinyl is easy to lay and easy to replace when damaged. However, it will never give you that sophisticated wood feel as nice laminated wood (the more expensive ones). Good Luck

Coretec is different from most vinyl planked floors. Most vinyls are very flexible (bend like a rainbow) and require some interesting forms of installation. Coretec is a "water proof" core made out of limestone (some other stuff as well). It is a true click together floating floor that is quite rigid. The install = identical to laminate flooring.The installation istructions say they do NOT need expansion gaps but large scale commercial installations (1200sf+) have discovered the large expanses do need some form of expansion gaps at the wall. I would look to see if Coretec has corrected it's installation guide but it is easy to assume it will need 1/4" - 1/2" expansion at each wall.

The coretec is an expensive, high(er) level product for bathrooms, kitchens, entranceways,etc. The planks are water proof but the seams are not. Don't worry. It would take a gallon or two left on a floor for 24-48 hours for the water to make it to the subfloor. The seams are pretty tight.

My company is looking into bringing in a vinyl floor over this "core"...but we have yet to find a price point that fits with our business model. If you can afford it go for it. Remember: vinyl will warp in direct sunlight (it heats past 85 F = "melted floor" in a few years).
