EPS foam lsulation

EPS foam board has been tested and accepted as exsterior wall insulation. Can EPS foam in bead form be used as loose fill exsterior wall insulation? This product carries the same fire and smoke rating as the board product.Intention is to use this product in older homes with no lnsulation in exsterior walls. This product carries an R2.3 per inch rating. Along with celotex board which is rated at R9 you can achieve R17 exsterior walls.

Unless there has been recent technology advancement, loose EPS beads are very hard to control as they are lightweight (very low mass density) and subject to static charge when moving (i.e. air delivery for placing in walls) making them very difficult to place in narrow cavities. Check in with Steve Baer at Zomeworks in New Mexico, he has extensive knowledge of the issues and in the past marketed a passive solar system called beadwall or something similar.

Code requirements will be the same as for any plastic insulation.
Thanks for the repy, however i have not exsperienced overwhelming static that would prevent the cavity from being filled completly.The only time static becmes a challenge is during the loading of the installation machine. Clean up is easy and due to affordability of this product i am still researching the facts. Also the machine is custom made and i am begining to research patends
I installed the Zomeworks Beadwalls in my own house when I built it 30 years ago. Static is an issue with the windows but won't be in MMartin's application. There will be significant static build up in the hose/pipe used to deliver the beads to the wall.

Probably the largest negative is that the cavity would require complete closure. The gaps at electrical boxes are large enough for the beads to leak out, even the cable openings in the romex boxes. If there is a hole in the sill, the stuff will drain through it.
In concerns to what thom had to say about zomeworks, I looked it up and descriptions are very brief. I believe this is some sort of auto insulating window run buy vacs and blowers. I also found a similar proccess being used on greenhouses or at least was speculated as a possibility. thom I am wondering if you could describe the zomeworks product you purchased?
Two panes of glass spaced about 3" apart. Styrofoam beads are blown in to fill the gap at night and evacuated in the morning. This allows sunlight in during the day for heat but 3" of styrofoam for insulation at night.

There are separate compartments that store the beads and the beads move through pvc pipes with positive/negative pressure created by vacuum motors.

My house has beadwalls going down the south side. Most of the south wall has Trombe walls inside the beadwalls. The glazed wall has 8@ 4" X 12' windows and 2 @ 4' X 8'.

My son, currently doing his architecture internship, was in class a few years back when the professor described the beadwall system. He said he believed there were no working systems in existence. My son explained that our system works just fine.
