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 The Measure of a Man: A Spiritual Autobiography The Measure of a Man: A Spiritual Autobiography is an autobiographical work by Sidney Poitier. On January 26, 2007, Oprah Winfrey chose it for her book club. In this memoir, Poitier, looks back on his celebrated life and career.
