When we bought this, it was on a *significant* sale, like 50% off or more--I think Home Depot was clearing some out. Really lucky timing.

Easy to cut and fit
This is an excellent insulation product. I was insulating my garage and the end walls where the rafters are located is angled. I was looking for a product that was rigid enough to stay in place by press fitting it in between the 2 X 4's. I decided to try the Comfortboard 80 and it worked very well, I found it very easy to cut and fit into tight spaces.

Warm and snug
The quality is bang on. Layered this up on the foundation wall in the basement. And then mounted in place was strapping. Very satisfied with the ease of installation.

Versatile material
I have a century home that’s double brick. Horizontal wood strips were embedded into the brick, with vertical slats attached for holding the lathe and plaster. I gutted all aspects of the old vertical slats, sealed any cracks/holes in the masonry, and added new 2X3s as vertical slats... 16” apart. I then had to determine what to stuff in between. At first I contemplated ridged foam, but I hate cutting it.Then I thought about slicing safensound bats like slicing a loaf of bread, but that seemed impractical. Finally, I found this product for basement walls, and decided to give it a try. Comffortboard 80 Cuts easy. Tight fitting. Conserves space. Will last a lifetime.

Easy to work with
I chose safe and sound to insulate our son’s room that we were building. He gets loud when he games online with his friends and we needed sound proofing that was inexpensive and easy to install. I love the product. Very easy to work with which was great because I’m a novice at home renovation.

Great Purchase and Easy Install!
Wow! I purchased 30 bags of the ROCKWOOL Safe 'n' Sound and was able to install it all by myself. I calculated that many bags on Rockwool's bag calculator on their website! Very accurate.. This product was very easy to install. Cutting around outlets, wires, and pipes was like cutting bread. Before the drywall went up, I could already tell a difference. I put the Safe 'n' Sound around all my laundry room, bathrooms, bedrooms, and in the basement ceiling. Not only does it provide sound proofing, it has other benefits as well. Such as fire resistant and no mildew can grow on it. I am so glad my builder let me install this product on my own. Would I recommend this product? Yes, 100%.

Exactly the product we wanted and needed!
We are renovating a 110-year-old stone carriage house. Rockwool has been our salvation for many reasons: exceptional thermal efficiency, super sound blocking, and mice hate it! Easy to install. We wrapped our new enameled steel tub with Rockwool for added insulation; my love of hot baths appreciates the extra 30 minutes I can spend reading in my tub before bed! And best of all, it has a low carbon footprint. Everything to gain when we opted for Rockwool instead of the irritating pink fluff.

This product saved our house!
We installed this in our basement ceiling 3 years ago. Our gas fireplace in the basement cought fire this weekend and the smoke and flames destroyed alot of it. The fire was so hot it had melted light fixtures and the fan off of the ceiling! We had double lined the ceiling with roxul when finishing the basement as our master bedroom is right over the gas fireplace and down stairs living room and we wanted maximum protection! Well unfortunately it was put to the test but it did exactly as it should! We had zero, that's right ZERO damage to the upstairs of our house above the fire! I can't say enough good things about this product! It saved our house and all who were in it! Thank you and I will never use any other insulation product in my home!

Best insulation out there.

Amazing Insulation for Home and Studio too
The first time I tried Roxul (now Rock Wool) was a few years ago to make some sound absorbing panels for my recording studio at home. They turned out better than professional panels at a fraction of the cost. The stone wool was easy to cut with a kitchen knife, and still holds it's shape perfectly after 5 years now. I liked it so much, I asked a contractor to use RockWool last spring when I was getting some work done in my home to help with insulating and sound proofing the walls and ceiling. I will soon be insulating my outdoor garage and I'm looking forward to using ComfortBatt for that project this summer. I probably sound like a commercial, but it does a terrific job and is worth every penny. I highly recommend it, you will not be disappointed.
