Help me identify this type of insulation
I have a house that has all exterior walls made from poured concrete,
no wood framing at all. The insulation on the interior is something I've never seen before and looks to be actually part of the form to pour the concrete into. It is black in color, very porous yet solid, lightweight, about 2" thick, and crushes very easily - even between two fingers. When it is crushed it turns to a sandy texture and emits a foul odor, kind of like rotten eggs. My first thought was pumice, but this comes in one foot wide by four foot long sheets. The house was built in 1953 so if anyone knows what construction methods were used back then and has any info please let me know. I'm just hoping its not some type of asbestos, or something else that is hazardous. Thanks, LW |

Where I live they use it sometimes between the concrete and the earth back fill. Concrete wall above grade? Do you live in a Edison house? Pictures please. |

I had a chunk of that stuff when I was a kid. Like pumice or a volcanic
black glass and it did stink. Now I know what it was for..Sorry I cant help but I know what you're talking about I have a house that has all exterior walls made from poured concrete, no wood framing at all.

wrote in message ... It may be the form they poured the walls in. There is a fairly new construction technique where they stack foam blocks with spacers built in them to form the wall, then they pour the center solid. ICF's, (Insulating concrete forms) are getting very popular. Makes a very energy efficient house also. www.integraspec.com www.standardicf.com |

So do you, or anyone else, know what this stuff is made of? I tried
asking all kinds of people what it is and about 95% of them didn't know what I was talking about. Those who did only saw it once, maybe twice, and didn't know what exactly it is made of either. I'm pretty confident it is the form the concrete was poured into and also doubles as insulation. I know it isn't asphalt board as mentioned earlier, and it definately isn't foam used in newer ICFs. |

We have it at the chemical plant that I work at as insulation on our pipes. I just spent the day ripping it off one pipe. It definitely smells like rotten eggs. This is due to the hydrgoen sulfide gas that is contained in the cells. The company that makes it provides a safety data sheet that will inform you of any hazards. It can be found online at the following address. http://www.industry.foamglas.com/en/...sds/us_origin/ Click on the 'FOAMGLAS Insulation (all grades)' link and that will tell you all you want to know. -- posted from http://www.homeownershub.com/mainten...ion-22104-.htm using HomeOwnersHub's Web, RSS and Social Media Interface to home and garden related groups |

That sounds like those 'glass sanding' blocks. As they crumble, smells like hydrogen sulfide, too. |

Most commonly known as "fart rock" it is non hazardous and still used today. -- |
