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.
