Answer: 
Dear Tom: Great question! First, radiant barriers require you to build / create a sealed air pocket on one side. This air gap provides almost all of the claimed R value. The shiny plastic bubble wrap has almost no R value. Second, reflective products are not effective in winter because cold cannot be 'reflected' and the warmer air inside your home is not radiant.

So unless you are trying to insulate

Dear Tom: Great question! First, radiant barriers require you to build / create a sealed air pocket on one side. This air gap provides almost all of the claimed R value. The shiny plastic bubble wrap has almost no R value. Second, reflective products are not effective in winter because cold cannot be 'reflected' and the warmer air inside your home is not radiant.

So unless you are trying to insulate a hot metal roof only in summer, standard insulation is more effective. Foam board provides the highest R value -- around 5 per inch for XPS and polyiso. Foam board is also very flammable, however, and must be covered by 1/2" wall board in any living space, basement, garage, storage space, etc. So if flammability is a concern, rock wool is a good alternative -- with R4 per inch. Rock wool is also much denser than fiberglass and is more effective at blocking air flow. Home Depot carries Roxul which is available in batts that you can use to fill stud, joist and rafter bays, plus a board version that installs just like foam board. Roxul is also great for firestopping, e.g. in a basement.

With foam or rock wool, make sure you also seal air leaks -- which are almost as important as R value. Recessed lights, gaps around interior chimneys, etc.

I hope this is helpful,

Mark
