  3. 3. Types of Framing <ul><li>Platform </li></ul><ul><ul><li>Used in most residential construction. </li></ul></ul><ul><ul><li>Can be used on both one and two story structures. </li></ul></ul><ul><ul><li>Pg. 442 </li></ul></ul><ul><li>Balloon </li></ul><ul><ul><li>Was once used extensively, but in recent years has diminished in importance. </li></ul></ul><ul><ul><li>Wall studs rest directly on sill, pg.444(solid sill/T-sill) </li></ul></ul><ul><ul><li>More stability than platform framing. </li></ul></ul>

Sub floor-pg. 454 <ul><li>Plywood, tongue and grove boards are commonly used. </li></ul><ul><li>The sub floor serves three purposes: </li></ul><ul><ul><li>Adds structural stability to the structure. </li></ul></ul><ul><ul><li>Provides a base for finish flooring material. Carpet/tile </li></ul></ul><ul><ul><li>Provides a floor for the carpenter to layout and construct additional framing. </li></ul></ul><ul><ul><li>When laying down the sub floor, use some type of adhesive to glue down. After gluing the sub floor to floor joists attach with metal fastener, screws/nails </li></ul></ul><ul><ul><ul><ul><li>This will prevent future squeaking and add 25% additional structural stability. </li></ul></ul></ul></ul>
  9. 9. Wall Framing <ul><li>In modern framing, walls and ceiling joists form one structural system. </li></ul><ul><ul><li>Walls support the ceiling, and the ceiling add structural stability to the walls. </li></ul></ul>
