    Answer This Question

    Hello Risa, After installation if attic access is required you would simply shift the Attic Stairway Insulator to the side and then replace upon exiting the attic. http://whqv8501/PublishedProjects/Attic%20Stairway%20Insulator%20Product%20Data%20Sheet/10009809%20Attic%20Stairway%20Insulator%20Product%20Data%20Sheet.pdf Thank you for your inquiry.

              I had one of these, but the insulation at the bottom edges gets caught in the attic door and rips. You mentioncovering the bottom edge with Aluminum faced tape that meets Flame Spread/Smoke Developed of 25/50. Can you give a brand name for this tape?
              ByOct 11, 2024
              1 Answer | 
              Answer This Question

              Hello Mona, There are several aluminum faced tape options that meet the Flame Spread and Smoke Developed 25/50 rating. Some common available tape options would include: Fasson (Avery -Dennison), Ideal (American Biltrite) and Venture (3M). Please check the tape manufacture to confirm ratings and with Home Depot regarding their stock and availability. Thank you for your inquiry.

                  Insularion NOT sealed -- TERRIBLE
                  The insulation is NOT sealed on the edges. So insulation is everywhere on ALL of the edges and you must touch it. It's worthless. It's so bad I would like to return this for a full refund...I just got it today and opened the box. Why wasn't this disclosed with the product???

                    Worth the money because it takes less then a minute to set up. You need this if you install an attic stairs. Saves on heating bills in the New Hampshire winters.

                      Very easy to install right out of the box and blocked off cold air from the attic coming into our mater bedroom. Helped change the room temperature at least 20 degrees. Very helpful with this last cold front we had of several days of below freezing temperatures. Also very easy to move out of the way when needing to re-access the attic area.

                      Being new to single-family homeownership in a New England winter, as a 70+ female I was able to easily lift, unfold and tuck the insulator all around the stair opening - by myself. The change in temperature was evident before I finished retracting the attic stairs. I expect that my heating bills will drop noticeably in the future, in which case this item will have paid for itself in one or two months of fuel non-use. And I didn't even have to build it myself, it was ready to use out of the box. Well worth the money.
