I'm pretty sure I've never seen this stuff before. It's installed in rafters as batts, held in place by cardboard sheets below. Papery consistency, now crumbling. The house is ~1923, but no idea when this was installed.

Anyone know what it might be? Thanks for any help here.

Hi Brian,

Thanks for sharing the brochures.   The middle link shows a lot of detail.  I found their heat loss savings calulations really interesting but way off if they are considering a house with no insulation to maybe an R-11.   I would love to know how they did the math.  For maybe a small two story home the pre insulation Btu numbers are pretty accurate for a home in the mid west with 6000 HHD's/

That IS an interesting link Brian!  I've seen a straw version of that material: 

Hey Rem, 2,000,000,000 BTU annual load?  What "small house" are you thinking?  

Most houses I've seen have 500-1800 total therm usage (insulated or not) until you get to great big houses.  If you factor in all the efficiencies of combustion and distribution before you even get to enclosure load, you cut the fuel BTU carrying the load by what, 25-75%?  

IDK, I think the layer of insulation vs none can have surprising results.  Those saving seem like good faith numbers, particularly when there is no accountability for saving being delivered.  They certainly could have projected a lot higher.  Think about 1990's window claims of cutting energy bills in half!  

We need tracking of results, that'll bring accountability to this field.  Promises of savings without tracking, how is that supposed to work?  How are you supposed to know if your promises come true?  

Imagine, Home Performance could actually be a rare industry that consumers could count on GETTING what they're PROMISED if results were tracked.  (The Solar industry has this figured out, we need to.) 

i agree with the others that's it's old rock or mineral wool bats
