Very Easy Installation

Would Recommend

Unskilled homeowner, yet installation of this product was easy. Batts cut easily with serrated blade knife and stayed snuggly in place without staples. I had no waste pieces during my install. I was able to use the trimmed pieces elsewhere. This was extremely nice as my rough cut stud wall cavities were between 17" - 22" wide, and every piece needed to be trimmed down from standard 23" wide batts. My wall temp went from 62 degrees to 71 degrees after install, now they are essentially room temp a...

I like to work with this product. I recommand it for sure

Would Recommend

I think this insulation is better than spray foam because its fireproof, waterproof and its also soundproof. Its a little bit expensive but it's worth it.

Very happy

We used this product for the walls and joist headers in our basement, which is a "split level" basement (ie. not true basement because it's only 3-4 feet below grade). Overall, we were impressed with the product, especially for two DIY hesitant people. We used both the R14, 2x4, on the 16" for wood and the R24, 2x6, on the 16" for wood. We purchased about 16 total. We used the denser batts for the joist headers and for two walls. They are much more stiff and not as easy to manipulate, but t...

Excellent product, easy install, way better performance

Would Recommend

Have used Roxul in bedroom walls, mudroom floor walls and cathedral ceiling, and basement walls. This is so easy to use, fits extremely well and reduces air movement in joist spaces. I have tested the way it repels moisture and held a propane torch to it. Just amazing and feel safer in my old home with it in the walls. The only negatives I have experience are that it is a bit tricky to install between old rough sawn studs and that the two pieces in the ends of the package take a while to "fluff...

The torch on a batt sold me years ago.

Would Recommend

The very first time I saw ROXUL at a show and there was a torch up against it and not burning at all. It has been nothing but ROXUL that I have used in any renovation.

I have used this product in my walls and ceiling

Would Recommend

I haven't found any thing bad, I like the comfort I get from knowing how well protected I am , from water and fire and mold protection. Plus the savings on my hydro bill.

I would definately buy this product again!

Would Recommend

I used this product to insulate my attic and was very impressed with this product. Being able to cut this insulation so easily to the required sizes was especially notable. The old insulation in my attic was extremely degraded. After removing the old insulation and installing the ROXUL, I could immediately tell a difference in heat retention and a decrease in drafts. I will continue to use ROXUL for any insulation project in the future.

I am very satisfied with this product.

My 17 year old son' re-insulated my attic for me this summer. I saw the product on a DIY video and could not believe how easy it was for them to do this project. They thought it was going to be difficult but when they discovered how easy it was, they finished the attic in no time at all.

This product was easy to install.

Would Recommend

My mom wanted to re-insulate the attic to prepare for the winter. I completed the project with my twin brother, Big Mike and it was so easy. We were 17 years old and completed the attic within less than 1/2 day. We would recommend this product for sure.
