Flooring and Roofing Terms
- Joist: Parallel framing members installed horizontally to carry floor and ceiling loads.
- Floating Floor: A floor system that can be placed on top of an existing floor (and does not need to be nailed down.) Tiles or boards are glued together rather than directly to the sub floor or floor.
- Dormer Window: A window that rises vertically from a sloping roof.
- Hip: The angle formed by two intersecting, sloping roof planes that runs from the eaves to the ridge of a house.
- Parquet Flooring: Woodwork floors set in geometric forms for design purposes.

- Galvanized: Any metal coated with zinc to protect it from rusting.
