ISDN | Integrated Services Digital Network. |
Joists | horizontally placed parallel beams to which boards of a floor or laths of a ceiling are fastened. (See also header joist, rim joist, and tail joist) |
Lintel | a horizontal member which rests exclusively upon wall (or jack) studs. The wall studs must have full-length studs doubled with them extending from the bottom to top wall plates. |

RESNA | Rehabilitation Engineering and Assistive Technology Society of North America this organization promotes the adoption of Universal Design through a Special Interest Group (SIG: 19). |
Ribbon Boards | boards laid upon a foundation wall to keep the horizontal beams from making contact with the concrete. |
Rim Joist | a timber or other support for cross members in floors or ceilings. In stairs, the support on which the stair tread rests. (Also known as stringer joist) |
Rise | in a staircase, the vertical distance between the tops of successive treads. |
Riser | in a staircase, that piece rising vertically between treads of a step unit. |
