R-value (insulation) typical straw bale houses have very thick walls and thus are well insulated. Snow is roughly R-1 per inch. Brick has a very poor insulating ability at a mere R-0.2 per inch; however it does have a relatively good thermal mass. Note that the above examples all use the U.S. (non-SI) definition for R-value. When determining the overall thermal resistance of a building assembly such as a wall or roof, the insulating effect of the surface air film is added to the thermal resistance of the other materials. In practice the above surface values are used for floors, ceilings, and
The Measure of a Man: A Spiritual Autobiography his upbringing and the invaluable legacy of his parents. Just a few years after his introduction to indoor plumbing and the automobile, Poitier broke racial barrier after racial barrier to launch a pioneering acting career.
