Owens-Corning seems to be having difficulty marketing and getting dealers to stock any decent quantity of Miraflex insulation.
When I inquire about the stuff I am met with “huh ?” and have to explain what it is.
Of all alternative insulation choices this seems most promising besides dense pack cellulose.
Anybody out there use the R-25 batts for the attic ?
(I have only foil bags and want to avoid using fiberglass and leery of blowing a foot deep layer of cellulose over all the electrical wiring and junction boxes in case I need to access them later.)
I realize Miraflex is a form of fiberglass but the samples I’ve handled shows promise in ease of handling and safety.
And I like the idea of being able to move them around with ease in case they need to be repositioned or moved out of the way if needed.

I don't know why this one is back at the top, but I'll offer a modest response. I bought a van load of this stuff cause pink and yellow itch me to death. One thing I did not like was that O-C seemed to have no quality control on it: that is, the density of the glass throughout the batt varied widely- very thick and then two feet down there was hardly any there. And it is too slick and limp for anything other than flat application, I got it on sale at the insulation supply because the insulation contractors don't seem to want it. I found I much prefer the wrapped Johns Manville yellow, but don't know what all thicknesses it comes in.
*Thanks, lonecat.Same story with Johns Mansville's encapsulated products - nowhere to be seen around this neck of the woods.The slick and limpness with the Miraflex would be ok for me because it would be used in the attic. But the quality control problem is disturbing. And they are charging a premium for the stuff.
*Fill er up with cellulose, you can find that stuff if you ever have to bad enough. I put about two feet in my attic- today it was 99 degrees out and 72 upstairs while I was sanding sheetrock.
*If you are worried about finding junction boxes or light fixtures, take a piece of that colored plastic marking tape and staple it next to the box and to a roof rafter. Then, when needed you have all these flags to point you in the right direction.Considering cels can be moved with a snoww shovel, rake, or shop-vac I didn't consider it inconvenient for future work.-Rob
*Thanks for the encouraging note on cels.I had basically narrowed it down to using the stuff but was intrigued by Miraflex and got sidetracked.Will have to start marking all fixtures and boxes in the attic in addition to sealing all openings and cracks.Seems it takes longer to prep the attic then the actual spewing of cellulose.
*as with most things, the preparation is 90% of the work.-Rob
