Questions & Answers

Q:Can I put faced r30 over top old blown in insulation without a vapor barrier in my attic on the floor?
by|Jun 11, 2024
1 Answer
Answer This Question

A:  You may install unfaced insulation over exiting insulation. Our recommendation would be to run it periductular to the existing insulation.

    Q:Can you staple face to studs to hold in place
    by|May 30, 2024
    1 Answer
    Answer This Question

    A:  You may face staple the insulation but the best practice is to check with your local building codes and also check with your drywall contractor. Drywall contractors generally request inset stapling.

          Emily and Julio acted fast on loading a big order
          I have a big order for a lot of insulation and the team came out and were lightning fast on helping me get it loaded up in both trucks. Thank you very much.

            I am very pleased with this. It was a first for me using this brand and won’t be the last. The cut ability of the insulation seems much greater than “the pink stuff”. It came to my relief that it was packaged very tightly in one bundle, palletized and wrapped in tyvek type plastic which kept it bone dry on the rainy drive home. 100% recommend buying this bundle from The Home Depot!

            Remains flat even after after a day wait. I wonder if I’m getting the proper R factor rating? Paper is offset to one side making it hard to install.

            Wrong price or label for this product.
            This product was supposed to be a R19 but in fact it was like a R13. The price was extremely high for the product density. Will not buy this product any more until it improves the quality and density or fix the issue of the wrong label for the product.

              Worked Great for the Shop!
              I used this for the walls in my 30’x40’ shop. This worked perfectly as my walls are framed with 2x6s running horizontally and spaced 24” on center. Two pallets (24 rolls) were sufficient to insulate all the walls which are 16ft tall.

              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.
