6mm is the thickest wear layer we have available. We recommend it in homes with high footfall, or medium to heavy footfall commercial environments. These floors tend to have the longest guarantee as the wear layer thickness ensures greater longevity, but with this also comes a higher price than out thinner wear layer options. Luckily however, quality is guaranteed at Luxury Flooring, and our prices are the low. Buy in bulk to make even further savings.
