Space Blankets as reflectors

I was just thinking about material to use as reflection to line my cabinet grow. Aluminum foil can cause hot spots on the plant leaves so I don't wanna use this. I don't know if I can get any mylar, I don't like odering stuff on the internet and all. Has anyone ever used Space Blankets as reflective lining? How well does that work? Any thoughts?

Actually a guy on OverGrow lined his cab with space blankets he stole from work. Seemed to do well as I recall.

If you have a lowes or menards go to the building supplies and look for a Styrofoam with a reflective surface. Its 4 feet by 24 and its folded up in panels costs about 13 bucks.

I heard of this from a friend that it works very well actually and that his friend had a successful large crop from using it. As for where its sold i dont know. Possibly in stores. You should reasearch it.
