What Our Customers Say...

Our custom built home has Nu-Wool in the walls and attics. We choose Nu-Wool due to its high recycled content and for sound absorption. By also insulating our floors and interior walls, we do not hear sound from room to room. Our previous home had very little sound absorption, and we can definitely hear the difference.

What is really exciting for me is when I bring a homeowner back to the home after it has been insulated, and their response is "Wow, this is amazing, it's almost soundproof." For me, that is when I know I have entrusted in a high quality product and why I use Nu-Wool in my custom homes.

Having Nu-Wool installed in our home was an easy choice, because it is all natural and doesn’t contain any harmful ingredients. Plus, we tried to use as many eco-friendly products as we could during our build. We didn’t even realize that it would be so quiet, so that is any added bonus of using Nu-Wool. We would definitely use Nu-Wool for future homes.

The fire department said that, that wall of Nu-Wool insulation acted as a barrier to give us time to get out when our house was on fire… Nu-Wool is definitely what you should choose if you are thinking of the safety of your family. View Video Testimonial>>
