"The materials discussed on this blog post have been open cell.
To my knowledge, one customer in town did actually have a blown-out wall that occurred a few hours after installation (there are about 70-90 in my service territory…"

George M. Matthews replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Here is your fix.
Require infrared testing of each job wanting govt money as rebates.
What type of foam is this? All the foam pros in the Bay Area tell me they are scared to death of putting foam in walls as they want to avoid drywall…"
Ed Ballard replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."My experience w/ injected foam is even if it is installed well and fills all cavities, it still has the problem of shrinkage. I went through a training a year ago at a foam mfg. I took a form with a plexiglass cover w/ me and had it injected. The…"
tedkidd replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Great pictures, thanks!
Exactly what I would expect to see from an expanding foam inside an invisible cavity. This, blown out walls, or both.
AirKrete or dense pack cellulose are the only cavity solutions I've…"
Silas Hoeppner replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Ed - I agree with you on the interpretations of the IR photos. Please see my post from 5/27, specifically the comment to David & Curtis re verification and IR interpretations.
As far as verification - shy of pulling down the…"
Silas Hoeppner replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Andrew - First, I noticed you provided none of the following:
1. Do the manufacturers provide installer training
2. Procedure/s for the "checks that have to be adhered to when pumping foam in place"
3. The pudding, i.e.,…"
Ed Minch replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."I agree with your third-party verifier comment. However - who is that? There is an IR shot included in a comment posted on 3/1 about foam - see above. I can think of a couple of different interpretations of the hot spots that show…"
Andrew Biser replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."The sky does not fall because foam is used for insulation.
In the dynamic world foams hold their insulation value better than fibers. As humidity fluxuates so does the r-value of cellulose and fiberglass. ( I wonder if salesmen tell this story?)
All…"
Curtis Dean replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."This whole discussion brings up an important tool that many of us in the utility incentive world are missing: third-party verification. So often due to lack of time or knowledge, we accept a manufacturers claims as fact and move on. And it is…"
Erin Buchanan replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Silas,
The particular insulation I refer to in this discussion is a "dry urea-formaldehyde powder resin", which is a dry powder that is mixed on-site with water. So it's not exactly the same as the stuff from the 70's,…"
Andrew Biser replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Silas,
No, I do not agree. The applicator has complete controll over the manufacturing of the foam . If the mix is off, if the resin is old, If the ratios are off, the foam may appear good and ready for application. But is the…"
Erin Buchanan replied to Erin Buchanan's discussion Rebate programs for injection foam? Not sure."Silas,
We agree with your last sentence in this post above and have been looking into this. A couple of months ago, our utility has banned this product from our list of products eligible for utility incentives.

Erin Buchanan replied to Steve Burke's discussion Urea Formaldehyde Foam Insulation (UFFI)"Matt,
Sorry for the delay.
A point of my own clarification: Neither I nor my co-workers were actually using IR as a real-time guide - a local contractor claimed to use IR in a real-time capacity during their installations, but…"
