Flooring
A solid hardwood flooring quite simply is a flooring made from many numbers of different types of tree or species of tree but is manufactured from one single piece of wood.
The alternative is an engineered board and the key difference to the engineered board will have a top layer of hardwood with a manmade back. The hardwood flooring will normally be tongued and grooved this will appear on all four sides of the board which means they will link together and you can install them without seeing any gaps.
