Has anyone used the NuWool product (Blown-in cellusoe insulation

Mark_46

but no.

I looked into their product as I got a solid recommendation from Brad White, a very knowledgeable poster on this site.

But Nuwool is supposed to be installed by certified installers. It is one way they control quality. With that said, you must work with the certified installer for your area. In my area, the installer was still a fairly new up-start and was mostly geared towards new construction/open wall installs. Like K-13.

Bottom line, the installer never submitted an estimate which always means to me they don't want the job. I was heading towards using Nuwool but the installer forced a change in plan.

On a similar note, I chose an installer who landed up being nothing less than excellent. And knowing that most cellulose insulation is the same I chose installer over product. Cellulose insulation is mostly ground up newspaper treated with fire and insect/rodent repellant. Not much more to it than that. The material he installed/I got is Greenfiber Cocoon2.

NuWool insulation

Has anyone used the NuWool (blown-in cellulose insulation)product. I'm considering using it on a 75 year old 2 story house with only 6" of fiberglass insulation in the attic.
I was interested in how it compared with standard cellulose blown-in insulation and with the foam injected insulation.

i have seen it fall out of a wall...

leave dead air spaces behind conduit and pipes...then there is some "issue" with another aspect, if you as an installer add moisture to the stuff to get it to hang together on a wall.....where do you figure it is going to live on the other side of your vapor barrier?....

my guess, to help you along with the thought is.....within the wall.

Sounds good to me

Homeowner here. It's what we're having installed, after much research. My understanding is that it's only mixed with water when used in new construction so it holds its shape before drywall is installed. In a retrofit situation, yo're simply filling a bounded void. As with any of this type of product, you need to be concerned about underfilling a space- plaster oozing between lathe can prevent proper installation. Insist on seeing an infrared image after the work is done to ensure that there are no cold spots (empty pockets).
This stuff in particular seemed attractive because of the relatively low cost compared with the spray foam (which has just gone up some more) and good packing and anti-mold properties. I'd go for it!
Good luck,

Poor installation

Weezbo

You must have seen a very poor installation. Done by someone not very good at installing cellulose.

When done properly, cellulose gets in all the little nooks and cranies. There are no voids or dead air spaces.

Wet spray is supposed to be done with very little moisture, mostly it is something like Elmer's white glue. And it is done on open walls with no drywall or plaster. You must wait a few days to close up the wall.

When blown into a closed wall no moisture is added at all.

No moisture added when blown into an attic.

not all certified dealer representative installers are =

Had foam injected in walls of my old house. I like it from the standpoint that it fills the void completely and does not pack down like cellulose supposedly does. By the way I also decided to take out the old rolls of fiberglass in the attic and put in a thick layer of icynene foam. Supposedly the greatest heat loss is from openings between the insulation rather than through the insulation. While they were here I also had them spray the areas around the joists in the basement. That is really a big heat loss area. Overall I am very happy with the results.
