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 in continuing deterioration of compliance with Conventions 87 and 98. The Government responded to the complaint by outlining the national conditions that led to the BCII Act, which included the Royal Commission’s finding of a culture of lawlessness in the building and construction industry.
