Karndean's floors come in a number of thicknesses and wear layers which determine their suitability for application. For commercial installations you must use a product with at least a 0.5mm (20 mil) wear layer. The thicker the wear layer the more durable the product. The thicker wear layers allow us to add more design features in to the product including a heavy registered emboss and bevel. For the most demanding installations we recommend that you choose something from either our Art Select or Da Vinci range which come with a 0.7mm (30 mil) wear layer.
