The blown in fiberglass I see. What is with the gold flake in the picture though?

That is what I am more worried about. Could have been removed previously and still have some traces left over.

It's the flash reflecting off stuff. You can see it throughout the material, especially on the full size pics from the camera.

Probably certified to be asbestos free at this point.

That being said, asbestos is a great insulator...just not good for the lungs!!!

I was on hold for awhile today, so I rescaled each batch of images from yesterday (rim joist, attic) and added min/max points. Each group is scaled the same so you have a better reference to compare against for those areas.

I'm still on hold...

other side of the chimney.

I did foam all the romex/bx cable penetrations also, just no pics of them. Once it gets cold again I'll get back up there with the thermal camera to look for more spots. I found one spot where there is a good 1/2" gap between 2 boards all the way across. Great Stuff Pro works great for that...

Looking good.

Obviously all the K&T wiring is dead now?

Actually, no, as I found out. There are a couple of very short legs from junction boxes to light boxes, like a few feet in 2 different places. I'm planning on replacing them.

You got the fire-caulk right, though I wouldn't use EPS (or any other foam) right next to a chimney, if that is one.... tin works well, pp.23:http://apps1.eere.energy.gov/buildin...ing_report.pdf

Looks good other than that. If the chimney has a flue the distance to combustibles from the brick changes some...

PS. Keep the pictures coming!

None of the chimneys are active, all fireplaces are blocked permanently---they are well over 100 years old. They aren't used for gas appliance venting either, both the furnace and tankless water heater are high efficiency/condensing that vent horizontally out of the house.

Once it turns cold again I'm going up in the attic with the thermal camera again to look for more problems.

Keep them coming. Looks great.

Crazy that some of the K&T were still live.

So today since it's cold again, I rescanned some of the rim joist areas I've insulated just to verify my work. I'll get up in the attic later to look for more air leaks with the camera.

Here's a before:


And an after, different angle though because there is a shelf unit in the way now.
