With high-quality vinyl, the wear layer is primarily important, meaning the thickness of the décor. Additionally, the surface treatment comes into play. But as a dog owner, you have to be aware that it does not mean that a high-quality floor will not get scratched; that is absolutely unavoidable. A thicker wear layer simply means that the floor will withstand wear and tear for a longer time. Vinyl floors in private areas usually have a wear layer of 0.3 mm, whereas in commercial areas, floors with a wear layer of 0.5 mm are more commonly used. So, if you have pets, I would rather choose a floor with a thicker wear layer, which is also more expensive. It depends — and please keep this in mind when purchasing — primarily not on the total thickness of the floor, but on the wear layer and surface treatment. The overall construction, whether click systems with a carrier plate or solid vinyl, floating installation or glued... all these factors add up and determine the price.
