How much additional energy is use to make the extra materials needed? The energy produced by a floor will vary by orders of magnitude depending on where it is installed, but I suspect there will typically be a net loss in energy over the lifetime of the floor if this is factored in. It may also make recycling of the timber more difficult if not impossible in practice, so the environmental impact is probably a negative one overall.
