Facts About R value
will the critical value of r decrese as n increases Some quick facts about R value are:

  • One type of insulation maybe thicker or thinner, but if the R value is the same they should insulate equally.

  • R value performance testing is done in a 70 F environment with no air movement. Ironically enough, when you need insulation the most you're generally not in these ideal temperatures or conditions. This can result in the rated house insulation R value being higher than the actual effective R value.

  • The average recommended R value of insulating material for basement insulation in North America is R-12.

  • The R value in house insulation is substantially lowered when there's any air or water/moisture leaks.

  • The standard R value for house insulation varies based on climate and temperature

  • 1 inch of insulation is = to 30 inches of concrete.
