I recently heard that the 1/2" or 1" bubble wrap used for standard shipping materials has an R value around 2 (which I think is pretty good considering that a lot of the spray-in wall foams have R values around 3 and 4).

I know that some people use bubble wrap as a temporary insulation on their windows, but has anyone used it to supplement existing blow-in attic insulation? It's so inexpensive and it seems like it would be great to fold over a few times and put in some draftier areas of an attic. And I'm just curious if there are any negatives to using it.

I think that if it was really that good, more people would be using that.

But that's just my hunch.

I'm sure it's not rated for fire safety.

yeah, I was just wondering... because people would not have thought of using shredded jeans or treated newspaper or wool for insulation a number of years ago--and now these are becoming more popular. But bubble wrap is a lot less expensive than these materials and it could easily be laid on top of existing insulation or put in 'problem' areas of the attic. For example, where I live, the summers are so hot and the south side of the house is always the problem area. :-) And I think it would be much less expensive to put down this wrap (and fold it over a few times). Plus, it would keep the existing blow-in insulation more in place.

I've heard of old rubber tires being used. Sounds like a good idea.

The stuff burns too well to risk as insulation IMHO. I would not use it except as a temporary measure. Use fire rated insulation instead. Check if your home owner's insurance has limitations on insulation materials. This is not an area where cheap pays off.

I never considered the cost of real insulation to be so costly that I had to look for/think up substitutes.

Well there would be a HUGE one at my place if I used it.

I'd turn into a bubble popping freak and probably have compulsively ruined the lot in a matter of days.

And bubble-popping would definitely kill the R-value too!
