Rated 4.0 out of 5.0 by KeepTryin I prefer working with Roxul over fiberglass insulation. It's not quite as itchy as fiberglass, but it's not itch free either. I always wear a dust mask working with Roxul, because particles become airborne as you work it into place.
It fits snugly in wall captivities where standard stud spacing was used, so it appears to provide better protection against air infiltration than fiberglass. For areas where the insulation needs to be cut, it cuts very easily with a bread knife.
The only reason I gave it 4 stars instead of 5 is that cutting around electrical boxes and "grooving" for electrical wires is kind of a pain because the material is a bit "crumbly".
I especially like the fact that Roxul is fire resistant.
Also, I'm sure that people will tell me I'm misinformed, but I don't feel comfortable using foam insulation. I'd be concerned about foam's flammability and its potential for off-gassing. I don't have those concerns with Roxul.

Rated 5.0 out of 5.0 by skulld WHY?
Would anyone use fiberglass insulation again? Simply put, Roxul is AMAZING! R_15 value, fire resistant, water resistant, mold & mildew resistant, sound barrier, ZERO WASTE and cuts easily with a serrated knife! NO MASK! NO ITCHING! NO STAPLES! NO BRAINER! Insulated a 112 sq/ft wall in 20 minutes! Sure it is a few dollars more than the pink stuff, but if you ever insulated an area with the pink stuff, you know the prep, the aggravation and the clean up. I will never buy the pink stuff again.
**TIP** Use a framing square to make straight cuts with a serrated bread knife in a sawing motion. Stack cut pieces.

I WILL NEVER BUY FIBERGLASS INSULATION ANY MORE ! ! !
It may cost more but it has a higher R-value & the installation is SO EASY & FAST, no mask, no gloves, no long sleeves, no stapler, no scissors, no razor knife, just a bread knife & T-square. SO SIMPLE... cut slightly oversize & push in place.

Rated 5.0 out of 5.0 by Madmax26 Rock Wool Is So much Better!
Purchased a home on the Connecticut Coast built in 1930. Home has no insulation at all.
Roxul has a higher R value, better sound proofing and is a great Fire Stop!
It is very easy to work with. I found an old bread knife to cut it with and after a very short time got the hang of cutting it! Roxul doesn't have the flying particles and dust like Fiberglass. I find it not to be itchy at all!
Once the inside walls were opened up and the Roxul was installed, the sounds from outside greatly diminished. It fits so nice between the studs and stays put where it's placed! Take your time cutting for wires and outlet boxes and you end up with a tight insulation job! The video on their web site helped too!
After the Roxul I added 1" Polyiso foam board and then sheet rock to give me an R value of R21!

Rated 5.0 out of 5.0 by TileBuyer This stuff rocks..
I've used this product in several different applications. It works fine and is much easier to work with than fiberglass insulation. It tears easily to fit into unusual spaces as needed. My only complaint is that it is significantly more expensive than some of the other options. I'm not sure I would use it to do an entire house but for targeted applications, it's great.

Currently in the middle of finishing my basement framing. Ive been limited to working only an hour or two at a time on weekends as the noise is too much for after hours. We have a few ducts that run directly from basement to the 2nd floor that I figured were the noise pollution culprits. I put around 3 layers into the joist cavity completely sealing off the duct run. While it is not sound proof there is a noticable difference. After going through the 3 ducts leading to our room and the babys room, i now have wife approval to work after the kid is in bed. Well worth the money. Im going to be using this in the wall cavity and joists above the entertainment room as well as a few other places. I was really skeptical after doing plenty of research online, but this worked like a charm. Note that my local store didnt carry the safe and sound, but this certainly did the trick.

Easy to install and very efficient in terms of limited waste. You will be satisfied, I purchased in bulk and the square foot price beat the competition locally by $0.15 or about 23%

Rated 5.0 out of 5.0 by CSB Super easy installation, insulates great
Noticed an immediate benefit in the garage where I installed this insulation. It was extremely easy to install as it stays in place once you fit it in between the studs.
