What Customers Are Saying

Customers overwhelmingly praise this insulation for exceptional thermal and acoustic performance, noting warmer homes, reduced energy costs, and significantly dampened noise. Installation is remarkably easy—it cuts smoothly, requires no special tools, causes no skin irritation, and fits snugly into tight spaces, making it ideal for DIY projects and renovations. Most customers declare they will never return to fiberglass, citing superior R-value, better durability, and resistance to fire, mold, water, and insects. A few mention blade dulling during large installations, but this minor drawback is vastly outweighed by overwhelming positive feedback.

Never Easier

Would Recommend

My husband and I used this product because it was recommended to us. The product is very easy to use, it comes in manageable sizes. If it is needed it cuts much easier and with less mess than other insulation products. It doesn't require staples or fasteners to stay in place. We have used the safe'n'sound in our basement as a fire block and sound barrier. It makes an immediate difference. We just installed the comfortBatt in our garage addition, there was a noticeable temperature differenc...

Stop shopping and just buy Roxul now

Would Recommend

My wife and I gave ourselves the unenviable task of replacing the 30 yo pink insulation in our unfinished basement. The several thousand sq. foot project was onerous and the job stretched across several weekends. When my wife and I got rolling on the job, she found Roxul so easy and pain-free to work with that she keep right on charging through the job all alone during the week while I was at work. I can safely say she did 80% of the +2000 sq foot basement on her own. Top props to Roxul for m...

NEVER BUY ANY OTHER BRAND AGAIN!!

Would Recommend

We use Roxul on every renovation product we do. Insulated a Garage in 95 degree heat, when the garage maintained a 72 degree temperature. It cuts cost on heating and cooling a house bc of the far superior insulation properties is has over other brands. It won't sag over time either like other brands, making your house envelope not sealed. Ever since mike holmes introduced it on his show, i was waiting for it to come to the United states. I would like for Roxul to be an industry standard in the b...

Best product out there

Would Recommend

Love it!

Would Recommend

This stuff is great. Consistently my favorite and go to insulation product. Resistant to everything, easy to cut, easy to install, and not as itchy as fiberglass. Plus, basically fireproof, which is why I am now installing it in my garage. No worries about where stray grinder sparks land, now! Only negative is that for the same sq footage, the product to fill wider (24inch) stud spacing is more expensive, which is kinda bogus.

easy install and snug result

Would Recommend

I installed this in my basement because I want to use it for thermal heat as well as noise reduction. It was easy to cut and install. It fits nice and snug. It is easy to carry in my car and it is environmentally good for my house both in its manufacturing as well as saving money on heating costs. Overall very pleased with this product.
