caryseidner Posted August 26, 2008 Report Share Posted August 26, 2008 Can anyone tell me what this is? I found it at an exterior wall in a crawl space. I swiped my hand across it to try and figure out what it was, and it disintegrated in my hand. Insulation? Foam backing for retro waterproofing system? Sorry. I know the pics suck.

Bill Kibbel Posted August 26, 2008 Report Share Posted August 26, 2008 I don't know what the stuff is that looks like hair or fur. It looks disgusting considering I just checked in here while taking a break and eating my lunch. The foam is UFFI - urea-formaldehyde foam insulation. Since it hasn't been installed since 1980, it's out-gassed long ago and is no longer a concern. Quote Link to comment Share on other sites More sharing options...
caryseidner Posted August 26, 2008 Author Report Share Posted August 26, 2008 Thanks (again) Bill. It does look like fur or hair in the photo. There was a paper or moisture barrier on the backside of it. Looked like some old and deteriorated form of batt insulation. Quote Link to comment Share on other sites More sharing options...
Les Posted August 26, 2008 Report Share Posted August 26, 2008 UFFI and it has been that way since it was installed. After a while in the field you get to know the different types of foam(s) and their characteristics. Quote Link to comment Share on other sites More sharing options...
