Can this be used under new siding


I wouldn't use our bubble material. The product that you would want to use would be our radiant barrier (RB4812550) This product does not have any R value but it does block 96% of radiant heat from entering your home. It is also perforated so it breaths and it will not cause issues with moisture or mold.
