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
Office of the Australian Building and Construction Commissioner of entitlements for those working in the building and construction industry. In 1997 the Australian Government put in place a National Code of Practice for the Australian building and construction industry. In order to be eligible to work on Australian Government building and construction projects businesses must be compliant with the National Code of Practice.
