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.
A partially constructed floor built with I-joists. An engineered wood joist, more commonly known as an I-joist, is a product designed to eliminate problems that occur with conventional wood joists. Invented in 1969, the I-joist is an engineered wood product that has great strength in relation to its size and weight. The biggest notable difference from dimensional lumber is that the I-joist carries heavy loads with less lumber than a dimensional solid wood joist.
