3. An in episode of Weeds I seen they had this type of insultation on the walls that not only seem to be used as a reflective but as from heat being seen from the outside, does anyone know what type that is? I didn't see that, but there are thermal blankets that reflect both light and heat. I know some people use these in their grow.
