Much nicer than fiberglass

I am a CIRS patient and needed to find a non toxic insulation to replace water damaged and moldy fiberglass insulation. I was able to install this insulation without protective equipment. There is research out on the benefits of sheep’s wool insulation related to moisture control which where I first learned about it. I was happy to find a product that doesn’t make me sick. Customer service was also excellent

A product you can be proud to put in your home.

We really like it. I think at first there is a slight wool smell if that makes sense . Nothing nasty or over powering. We are living in our house as we finish it out so we have had temporary walls, we put this stuff up and it's amazing. Our house is big and open and the kids and us, we're amazed at how well it insulates. I could not be happier and i love that i don't have to worry about us breathing in junk. Love that its easy to install, doesn't make me itch and we can leave it exposed while we work and we don't have to worry about it. Love your product, love that it's american made too!
