It was pretty hairy putting this up and it included almost having the main beam dropping onto the solar panels. It will be a lot easier taking it down.
I spent Friday and today putting the insulation in for the floor. My first choice was wool from Oregon Shepard but they didn't reply to my inquiries. I ended up going with rock wool and here are my reasons:
- loose fill has a lower R-value per inch
- loose fill has to fluffed up
- fiberglass is itchy and has a slightly lower R-value
- rock wool is pretty dense and will probably resist settling and shifting
- rock wool is fairly water resistant
- rock wool was $220 vs fiberglass $130
My little spreadsheet to help my choice
|Cubic ft needed||92|
|ruxul loose||ruxal batt||FG loose||FG batt||Cellulose|
|Coverage/pkg in cubic feet||22.49||18.24||56.63||35.89||18.12|
|Weight/cu ft (lbs)||1.47||2.31||0.53||0.83||1.40|
|Weight total (lbs)||134.51||211.56||48.57||76.37||128.24|
Now the fun part, installing it. I wore long sleeves, leather gloves and a mask. Rock wool is nowhere near as itchy as fiberglass and it washes off much easier. I found it would give slivers without the gloves. I've finished installing 3 1/2 bags out of five.
