It's about time someone addressed this issue. I has my home built with 2x6s just to inctease the r-value and I can still feel cold air blowing through. Where were you when I needed you?!

To say the way R-values are presented goes way beyond "misleading" I think its fraudulent and no different than a car dealer misrepresenting the gas milage of their cars

Terry thanks for the comment. I appreciate your frustration but keep in mind that the old method of rating walls was the only system available until the Effective R-value system was developed by The Dept of Energy. But now that a better system is available builders should be moving towards the new system when promoting the thermal performance of their walls.
