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.

Liked it better than the pink stuff, better consistency. Wish it was more available. Had to buy it by the pallet which this time worked out.

Thank you for your purchase of Knauf Insulation and your review. If you store is currently carrying another brand, you would need to purchase on dotcom. We continue to strive to take on additional stocking stores.

Take the measurements of area requiring insulation. This product covers 135.13 sq ft per bag. Take the sq ft required and divide by sq ft per bag to get number of bags required. If you area is 10’ X 20’, you will need 200 sq ft and will need to purchase 2 bags of material.
200/135.13 = 1.48 bags to complete or 2 bags. Hope this helps with your project.
