Carrying a name like NASA is bound to carry some weight when it comes to materials- however be mindful that this is NASA tech, and not provided by NASA themselves.

The finished product can look great and an R-value of 8. It doesn’t take up much room and it even comes with a reflective layer, that can help keep out moisture and heat- perfect for garages that get extremely hot in summer.
