Have you noticed how of all the wood flooring types there are, hardwood flooring in a room can truly turn it into something extraordinary like nothing else can? Just take your ordinary suburban drawing room and deck it out in hardwood, and it suddenly becomes elegant and cozy and dignified all at the same time. Exposed wood tends to be that way.
Look at the way regular hardwood flooring was originally done, and you notice that the way they laid it, they physically attached each strip to the underlay with glue, wood staples, nails and other such. The problem with this, as anyone who has lived in an old home with wooden floors knows, is each strip of wood reacts independently to the environment. When it gets humid or anything, each strip of wood warps, strains, bends and does other unspeakable things independently of what all the other strips around it does. You shouldn't be surprised with these wood flooring types to one day suddenly see them explode. The warping places some wood strips under so much stress that when something gives, those strips just bounce off.
