Engineered bamboo flooring hast several methods of construction including horizontal and vertical construction methods. What separates Engineered from Solid bamboo flooring is the fact that it is not completely made of bamboo grass. It has several other elements including a laminated veneer top layer and mixed bamboo/wood plies.
The backing of engineered bamboo flooring is a thin sheet of wood that is chosen to be far less dense than the actual bamboo. This allows for heating and floating installations. While cheaper to produce and more durable than solid bamboo, Engineered bamboo flooring is not great with water resistance. But if you are looking for a budget friendly exotic hardwood for your home, this is a great choice for you.
