UNIT 2: Installing Doors, Windows and Stairs


Introduction


Annotation:

People use doors, windows and stairs every day. These items must be installed in such a way that they will provide efficient and ergonomically responsive service to the building’s occupant.

With increasing awareness of energy consumption within a building, doors and windows should be constructed and installed in such a way to maximize their energy efficiency. The design of these items has changed and will continue to change as more demands are made for increased energy efficiency.

Each year thousands of people are injured upon stairs. The installation of such items, either on the inside or the outside of a structure, should not be the cause of any of these injuries.

Students with Disabilities:

For students with disabilities, the instructor should refer to the student's IEP to be sure that the accommodations specified are being provided. Instructors should also familiarize themselves with the provisions of Behavior Intervention Plans that may be part of a student's IEP. Frequent consultation with a student's special education instructor will be beneficial in providing appropriate differentiation.
