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.

    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.

            great batting and blown in insulation
            I have used all kinds of batt insulation and this is the best. The batting is better quality than most other types. It is packaged nicely and comes out of the package as it should. It has been a struggle not being able to get 9ft material or R49 batts though.
