Scotia wood is a type of trim piece that you can use to cover up the gap that is left after installing flooring around the outside of a room. This type of trim can come from many different species, including oak, walnut, pine and maple. It looks like an "L" shape except that the inside is rounded out. Scotia wood is generally easy to work with, and it is also very durable. It can stand up to a lot of wear and tear, which is why it is commonly used for flooring applications.
