Asked by Bear January 6, 2021

Tammy, what is a quote center? Also 5 bags would be too much. The wall is only 16' in length and 8' in height to the top plate.

How many pieces are in it

Asked by Skeeter November 2, 2020

8 pieces.

Should this (R-13) insulation be used in the attic or should we use R30 to R60? My handyman wants...

Asked by MM October 30, 2020

If you are installing in a side wall, you should use the product designed for wall construction. 2X4 you may use R11, R13 or R15. 2X6 you may use R19 and R21. If you are installing in your attic as a floor application, you will want to achieve a higher R value as heat rises. You may use loose fill, batts or rolls for attic floor installation.

The label says 116.25 sq ft.

Are thier any safety precations one should know about this product?

Asked by VonBurke January 22, 2020

Please wear safety glasses, long sleeve shirt and gloves when installing. If you are installing in an attic, you may want a hard hat due to nails in the rafters.

What is difference between this & the Knauf R-15. Both have same thickness, width and length. I r...

Asked by Raeka January 17, 2020

The higher the density, the higher the R Value. R15 has a higher density of glass than an R13. The same with R21 verses R19.

My basement walls have 2x3 studs. Can I use this insulation if I compress it a little?

Asked by Bobby January 7, 2020

You'll want to peel off an inch of the insulation instead of compressing it. It will fit if compressed, but you will lose more R value than if you peel off a layer.

Should you install polyurethane vapor barrier over the paper insulation for bedroom and bathroom ...

Asked by Tk November 5, 2019

You should only use one vapor barrier. If you use sheeting you should remove the kraft paper from the insulation. Else, moisture can collect between the vapor barriers.

Hi r13 insulation that is good for a basement walls ?

Asked by Abel November 1, 2019

If you have 2 x 4 walls it is what you need provided your basement is reasonably dry. If you have a wet basement you would probably be better using polystyrene.

Would this be OK for a walkout basement? This would go in the exterior whole southside ...

Asked by Batman August 26, 2019

I would recommend using ridged polystyrene because of the potential of humidity causing mold. If you use fiberglass you would have to use a poly vaper barrier against the block.

So easy to install!
We are first time home owners, and one of our first big DIY projects was insulating the attic. The Knauf Insulation comes in 16”x48” batts, which made installation a breeze. We were able to insulate the whole attic in one afternoon. Our friends and family were so impressed!! We owe it all to this quality product! Highly recommend.

Congratulations on your first home! That is a great first project that can lower your energy costs and improve the comfort of the home. We are glad to hear that Knauf EcoBatt Insulation worked well in your attic and thank you so much for sharing. Excellent photo!
We order by the truckload
I’m an insulation contractor with a few crews and we install anywhere from 25-40 truckloads of Knauf insulation per year. For years it has been our preferred brand for a few reasons. It is a very consistent material throughout which makes it cut more cleanly and install more smoothly. Other brands we have tried have actually had chunks of unprocessed glass in them. Others fall apart as you try to handle the pieces. It is a smoother fiber which makes it less unpleasant to handle. Other brands feel rougher. We also love that it is greenguard certified as well as the high recycled content. Overall this all translates into a better installation experience, which enhances the job outcome and makes a Grade 1 install more consistently achievable, and that’s what is best for our customers’ comfort and energy performance. We are proud to install this material.

This doesn’t seem to itch you as bad as the pink or yellow stuff! Cuts easily with scissors or razor knife, does not fall apart once it is cut. Expands to height stated on package or slightly higher. Over the past year I have used this product for insulating my garage, some areas in my basement, and attic. Very happy with this product. Great sound deading ability!

First, I am a DIY kind of person. I have had limited experience with insulation, so I read up a bit before starting this project. I was told when we moved in the house by a home inspector that the attic space would be better if I changed the loose fill insulation that they crammed between the plywood flooring and the ceiling with batting. While I may get better results with a higher rated R value for this project, this is what was available to me. My attic space allows me to put two bats down between the floor and the plywood. I just make sure to take the vapor barrier off of the top layer to allow it to breathe. I am not seeing any current issues with moisture in the loose fill, so I do not expect any issues with this batting. It was a perfect fit for my needs as I am on 16" spacing. I am not cramming it in the floor as there was enough room to place one on top of the other without cramming it down. I have worn the necessary protection while installing, gloves, long sleeves, mask, etc... I can say there really has not been an issue of dust or insulation just sticking to me. I do think it is true that this is a dust free insulation based on my experience. I can tell that 8 ft pieces are perfect fit for a standard wall. While I am using it for the attic floor, it appears I may have enough left to go around the walls in the stairwell to the bonus room. Curious to see how improved that may make the fluctuation in the temperature of the hallway and bonus room. I liked the fact that this is ECO insulation as well. This is definitely well suited for standard walls, 8ft high on 16" spacing. Seems to be a good quality product.

I noticed first off is the dark brownish color. not the usual pink or tan. maybe that is the recycled content ? it does feel softer to the touch and i did notice somewhat less particles in the air. as to the performance it seems fuller than some i have used which i think would add to the insulation performance. im using it in a 22x16 garage with 2x4 walls. so i will defiantly be able to feel the difference it creates. Kraft facing is heavy along with staple flanges. perfect for full length 8' wall cavities and cuts easily with utility blade.

Thank you for asking about the brown product. Our product is naturally brown in color due to no artificial colors or dyes added. We also manufacture using recycled glass that would normally go into landfill. KnaufInsulation
