Questions & Answers

how many square feet will this cover?

Asked by: goodyz
The previous answers are wrong (sorry guys!) Each bag covers ~30 sqft; there are 6 bats abt 4' long in each bag - it says so on the packaging. This individual page is for a pallet (12 bags of this stuff), or about 360 square feet.

I had to cut the sheets in half to fit in between the 24 inch joists. My husband installed the insulation. There was no insulation above the garage space, and now it's chock full. Easier to work with than fiberglass, but you still need a mask and gloves. Just a little itchy.

I installed this insulation in my attic. I have blown fiberglass insulation so I laid the Rockwool over the existing blown in fiber glass insulation across the studs so it creates a fire barrier and seals in the under performing fiberglass. i like the size of the insulation its easy to work with. Be sure to get the knife, use care when handling as it can tear. there is virtually no waste small pieces can be tucked into small holes so it seals in. The Left side has a flexible side when you install it you can adjust it easily. Be sure to face the side with ridges side out this is the face side the side with lettering. This product is more rigid than fiber glass, wear a dust mask when installing.

I converted a raised covered porch into a four seasons room, but even with hvac installed, the wood floor was way too cold in the winter. I watched a video in disbelief so I called Rockwool to confirm - product can be used under a covered deck and left exposed. I live in the humid south and they advised to not cover the underside it with anything else, like plywood, just leave it loose (I have trellis around the perimeter to keep out animals). The ComfortBatt has made a significant difference! Floor has not been cold again and room temp stays a warm 75. I am very impressed. The ComfortBatt also installs like a dream compared to fiberglass insulation. It cuts like bread, stays a firm consistency, and stays in place with little sagging. There were a few times I forgot my knife and just broke it apart to size it - it worked. Rips apart in chunks. I didn't use any wood or strapping material to keep it in place, so I will check in the summer to see if any has fallen out, but so far it stays were I put it. Worth the price!

Rated 5 out of 5 by from Does what it says. Had to redo an addition on my home, practically no insulation at all originally. Once this added, the room now doesn't lose cooling like it used to and it feels much better on the rare cold spell.

Rated 4 out of 5 by from Great Product Rockwool Comfortbatt is easy to install & retains it shape overtime. This product is more great for homeowner who live in a humid areas like Houston Texas since Rockwool Comfortbatt is resistant to mold & mildew which limits bacterial growth in your walls.
