Greenest insulation (mineral wool?)

[Steve]

Interesting article on TreeHugger:

What is the greenest insulation? The case for mineral wool (http://www.treehugger.com/sustainable-product-design/what-greenest-insulation-case-mineral-wool.html)

It would be pretty easy to use that insulation in a B&P project, I think...

Actually, this is what I used behind my chinking. It is fantastic. Cuts easily, compresses without loosing much, if any R-Value, isn't itchy to work with and costs about the same as fiberglass

But probably the best feature is how it repels water.

As an example, I had an entire wall insulated and nailed, but not chinked when a driving rain storm blew in overnight. It was strong enough to blow water 4 feet into the house through the window cut outs on the second floor, despite the 8ft overhangs. Next morning, the insulation was completely dry, the water never soaked in at all.

Don't let this thread die a quick death.

how expensive was it, Jason?

how expensive was it, Jason?

A bag of batts is within a few dollars of the pink fiberglass stuff. I used a total of 5 bags of R22 (5 1/2" thick) 24" OC batts (I don't know why, but the bigger batts were easier to work with (I had a bat of 16" wide stuff left over from a project, and the cutting wasn't as efficent).

Each bag was about $40, so not a huge expense (note, this is for outside only)

To cut the bats, I did the following. Cut the batt in half crosswise (now have 2 pieces 24x24)
Cut the 1/2 batts into strips the width you need (I rarely had 1" strips, most of mine were in the 3-4" range, with 2" and 5-6" as well)
Turn each strip on it's side, and cut with the grain to split it in half.
Needless to say, a batt goes along way.

If you do use mineral wool, get one of these: http://www.homedepot.ca/product/mineral-wool-saw/974658

I have been thinking about finding some local sheep owners and trying to gather wool for a while before my next build, I like the idea of using straight up sheeps wool for insulation

[rreidnauer]

I believe there's quite a bit more to it than just stuffing sheared wool into the log openings. Isn't the wool stripped of oils or tannins or something, then borate treated? I could be wrong, but I'm thinking that there is some process needing to be done before it's ready for use.

[rckclmbr428]

I'm sure there are people in the wool business that may advocate that, but why not just go Au Natural? Maybe I need to get a couple sheep to keep my yard mowed and just start shearing them...

[rreidnauer]

Yea, perhaps. I would run some tests to be sure, but wonder if maybe there is an odor issue. Like if it was humid. I don't know, just guessing.

Nothing smells worse than a sweaty sheep.

Now if we could just find someone around here that raises mineral sheep. :cool: Shearing them must be...interesting.

Dare I ask how you know this ? :D

[loghousenut]

Ask Bo.... He knows the real truth.

[jrdavis]

Ask Bo.... He knows the real truth.

Or you could ask an Iraqi...............
sorry -- 41 months in Iraq, you find out some interesting things.
scratch that -- 'disturbing' would be the right word.

[BoFuller]

Ask Bo.... He knows the real truth.

Okay, I admit Bo knows, but I'm not telling the sheep story. No way.

[Longhare]

Oh come on, Peep. If you don't tell, LHN will find a way to get it out of you.

Hmm, there was something said about jousting Peeps last weekend...

[loghousenut]

Bo has reason to be quiet about this one.... But Cousin Tom doesn't.

[LogHomeFeverDan]

Would it be prudent ......er........nah...... I mean you couldn't actually use the sheep itself I mean they'd have to eat........ ok sorry my mind is disturbing.

[BoFuller]

There's a spam intrusion.

[rreidnauer]

There's a spam intrusion.Yea, but how do we get LHN to stop posting?


Oh. You mean that other post. :rolleyes:
