Radiant Barrier Insulation

Does anybody know if that radiant barrier I posted a link to is worth a **** or not?

Not for what you need it for....you would be better off covering the outside of your garage with it.

You need this type of insulation, fiberglass with a foil backing. Spray glue your metal and stick the fiberglass and tape up your seams with foil tape....and also it will be much brighter in the shop area...win..win,
