The best way to assess the overall performance of the radiant barrier is usually to evaluate or determine the R-price of the whole assembly wherein it is included. Engineers and laboratory professionals do this constantly; R-worth checks are an proper way to check the effectiveness of the assembly
There will not be any conceivable instances, nor any conceivable way so that you can stack your foam, that enables your XPS to "dry in the vent gap." Nonetheless it doesn't should -- the XPS is just not damp.
One simple distortion is usually that "radiant barriers don't have any R-value". One of the most prevalent radiant barrier materials getting used today in development and renovation, like HVAC get the job done, is bubble foil. By Martin's individual admission, bubble foil has a measurable R-value, albeit minimal unless Element of an assembly (which is usually how the merchandise is tested and advertised).

The partitions of your house have been insulated with an item made by Reynolds Aluminum... Arriving in extensive flattened rolls of aluminum, they were being Lower to duration and after that popped open up by pulling together the flanges at the edges.
Q. " If I have been To place the XPS in the interior most part of the stack would not the foil block the XPS from drying to the vent gap?"
You can find is, needless to say, an air Area in the attic. Hence it appears that evidently this is the far better technique for heating climates, as it might protect against some warmth reduction from the home. Within an A/C predicament there must be an air Room over the foil to mirror the roof heat away from the residing Area.
The zeroth law of Thermodynamics states that two objects are in thermal equilibrium whenever they transfer no Power to or from each other.
