My concern is how the space blankets hold up at attic temperatures over time. My experience is that some of them lose their reflectivity with time.
The radiant barrier material I have in my attic is paper with a thin aluminum coating on one side. I also suspect the paper has a fire retardant in it. It has been up there for at least 20 years with no noticeable change in reflectivity.
Which brings up another potential problem with space blankets: No fire retardant.
