About 14 inches deep it looks like
It rained down all over me when I got up there to take pics
Around here they were doing it for free (adding more) because of the gas company incentives
Just about every house got more blown in
Some did not, like my old house, it already had as much as they could put in there apparently

 

Okay, you said "boards going every which way and no actual trusses".

These ARE trusses. That’s why the boards AREN’T going “every which way”, but all align. You can see the truss gang nail plates (Google for image) where different members butt together. I’m including a graphic that will help you understand what I’m saying as we go. Now, you’ll see why I said stick framing is better.

I'm not going to tell you to cut anything out as these are engineered to use the least amount of material already. Technically, that contractor may be ‘okay’ replacing the web member’s (see pic) in HIS own home, but I’d need an engineer’s plan to make those changes on any house I would work on. That being said, you can still rip OSB and fit it in the clear, flat areas (green parts of the bottom chord in the picture). This is where the 2’x4’ OSB pieces will come in handy. It will be a pain to fit them in.

Obviously, you'll have to remove most of the insulation in the bays, which will really drop the r-value. Or stack 2x4s edgewise on top of the bottom chord and sister together with 6-1/2” OSB rips screwed to the sides to tie them together, kept up ¼” above the ceiling drywall for shrinkage. Or replace with rigid Polyisocyanurate board insulation like R-Max (pricey, 3”x48”x96” sheets are about $110 plus shipping and you would probably want more storage area than a sheet of plywood’s worth).

No matter what, you’ll have to remove most of the insulation just to do the job. This is going to be a nightmare. Are you absolutely sure this is worth the trouble? Wouldn’t a nice shed be better? Or throw out some crap, instead of lugging it from house to house, never to be seen again.

 

 

Thank you
Good idea about the shed and I am building a pole barn at some point
I have a shed now but it's small
I have thrown out a ton of stuff and more on the way
Right, I think removing the insulation to do anything up there will be more trouble than it's worth
Thanks again

 

No problem.
And hey, if you build another shed, you can be like the modern classical composer, Arthur "Two Sheds" Jackson.
One of my favorite Monty Python skits.
Good luck, Brother.
