A friend plans to put in laminate flooring in his new house. He has received conflicting advice about the durability of the various thicknesses available with some people saying that the thinner quality laminates (6/7mm) wear just as well as the thicker, more expensive, ones. Any advice/guidance on this would be welcome. Also is it a good idea to put "water-resistant" laminates in kitchens where there is a risk of flooding from dish-washers or washing machines?
