Gender Identity. A person's internal, deeply held sense of their gender. For transgender people, their own internal gender identity does not match the sex they were assigned at birth. Most people have a gender identity of man or woman (or boy or girl). For some people, their gender identity does not fit neatly into one of those two choices (see non-binary and/or genderqueer below.) Unlike gender expression (see below) gender identity is not visible to others.
Sleeper joists are wooden boards installed on top of an existing subfloor that are typically used as support for hardwood flooring. The sleeper joists follow the same arrangement and spacing as the main home joists located under the subfloor.
Joists can be metal, steel or wood (Most cases are wood) and can be used for floor joists which are used when a house is built on a Pier and Beam foundation and requires wood joists to span an area and provide something to fasten the sub-flooring to.
